A plancha griddle insert for a gas grill turns part or all of the cooking surface into a flat top for foods that can slip through grates. My best overall pick is the Weber Full-Size Carbon Steel Griddle Insert for buyers who want a grill-specific full-surface option; the Utheer 25 x 16-Inch Cast Iron Griddle stands out for broad coverage, while the Charbroil Performance Series 12-Inch Insert suits smaller cooking zones. The main tradeoffs are grill fit, cooking area, material weight, and coating care: a larger plate offers room but can be harder to handle, while compact inserts preserve access to open grates. I compare all 15 options by their listed dimensions, materials, and intended use. Read on for the full breakdown and a guide to choosing an insert that matches your grill and routine.

Key Takeaways
Full-size coverage and compact flexibility serve different cooks. The Weber Full-Size Carbon Steel Insert and large 23- to 25-inch plates aim to turn much of the grill into a flat top, while Charbroil’s 12-inch insert leaves more grate space available.
Material matters as much as footprint. Cast iron is the dominant choice across the list, while the Weber Full-Size and SHINESTAR options use carbon steel; each material brings different handling and care needs.
Coated surfaces make a distinct maintenance tradeoff. QuliMetal’s nano-ceramic and the ceramic-coated Arribueno emphasize a coated cooking surface, unlike the care routine generally associated with uncoated cast iron.
Many listings share the same 17 x 13-inch format. GORGERILA, BIQetrae, Hisencn, Uniflasy, and Unidanho are compact-format alternatives, so buyers should compare grill fit and surface construction rather than assume the dimensions make them interchangeable.
“Universal” is not a fit guarantee. Several large inserts advertise broad compatibility, but the grill’s usable grate area, lid clearance, and burner layout still determine whether a 23- or 25-inch plate will work well.

More Details on Our Top Picks
Charbroil Performance Series 12-Inch Griddle Insert
This insert makes the most sense for owners of a Charbroil Performance Series gas grill who want a ready-to-use flat top without replacing their grill grates. Its 270-square-inch cooking surface is smaller than the Utheer 25 x 16-inch griddle, so it suits side dishes or a few portions better than a full family spread. The porcelain coating avoids the seasoning step required by some bare cast-iron options, while the grease slot works with the grill’s grease management system to direct drippings away. A raised sidewall also helps contain food during flipping. The tradeoff is narrow compatibility: unlike the GORGERILA, which is described for gas, charcoal, and electric grills, this is built around one grill family. Its cast-iron body may also be awkward to lift.
Pros:- Adds a 270-square-inch flat-top surface to compatible grills
- Porcelain coating is ready to use without seasoning
- Grease slot directs drippings into the grill’s grease management system
- Sidewall helps keep food contained while cooking
Cons:- Designed specifically for Charbroil Performance Series gas grills
- Cast-iron construction may be heavy to handle
- Smaller cooking area than full-size inserts such as the Utheer
Best for: Charbroil Performance Series owners who want a compact, coated insert for pancakes, vegetables, or burgers without extra seasoning prep.
Not ideal for: Owners of other grill brands or shoppers who need a large surface for cooking a full meal at once.
- Brand:Charbroil
- Material:Cast iron
- Dimensions:16.61 × 12.28 × 2.39 inches
- Cooking surface:270 square inches
- Compatibility:Charbroil Performance Series gas grills
- Surface coating:Porcelain
- Grease management:Built-in grease slot
- Warranty:1-year limited
Our verdict“Choose this compact, ready-to-cook insert if you own a compatible Charbroil Performance Series grill and do not need a full-width griddle.”
GORGERILA 17 x 13-Inch Cast Iron Grill Griddle
The GORGERILA is a flexible choice for buyers who move between gas, charcoal, and electric grills, or take a griddle along for camping and tailgating. At 17 x 13 inches, it offers more cooking room than the Charbroil Performance Series insert, while remaining less imposing than the Utheer’s 25 x 16-inch plate. Its reinforced thick base is intended to resist warping, and the matte enamel finish may help reduce sticking; the integrated groove gives excess oil a place to collect. That broad use case comes with handling and care tradeoffs: at 13.9 pounds, it is a substantial piece to move, and the supplied product information does not clarify seasoning or cleaning needs. Buyers who want a grill-specific fit or removable handles may prefer another design.
Pros:- Works on gas, charcoal, and electric grills
- 17 x 13-inch surface offers more room than the Charbroil insert
- Reinforced base is designed to resist warping
- Matte enamel finish and grease groove support less messy cooking
Cons:- At 13.9 pounds, it may be cumbersome to move
- Care and seasoning requirements are not specified
- Less cooking area than large formats such as the Utheer
Best for: Grill owners who want one mid-size cast-iron griddle for gas, charcoal, or electric cooking at home and on camping trips.
Not ideal for: Shoppers who need a lightweight insert, removable handles, or clearly specified care instructions.
- Brand:GORGERILA
- Material:Cast iron
- Dimensions:17 × 13 × 3 inches
- Weight:13.9 pounds
- Compatible cooking surfaces:Gas, charcoal, and electric grills
- Surface finish:Matte enamel
- Grease collection:Integrated grease groove
- Model number:1713
Our verdict“Pick the GORGERILA if fuel flexibility matters more than low weight or a model-specific grill fit.”
Utheer 25 x 16-Inch Pre-Seasoned Cast Iron Griddle for Gas and Charcoal Grills
For cooks who want to prepare several portions at once, the Utheer’s 25 x 16-inch surface gives it a clear capacity advantage over the 17 x 13-inch GORGERILA and BIQetrae griddles. Its pre-seasoned surface means it arrives ready for cooking, and reinforced support ridges are designed to promote even heating across the broad plate. The built-in grease trough collects drippings, while detachable handles offer a way to lift or store the insert without leaving handles attached. The size is also its main limitation: it may not fit every gas grill, so measuring the cooking area before buying matters. Cast iron adds considerable handling weight, and this large format is less suited to cooks who only need a small griddle zone.
Pros:- Large 25 x 16-inch surface supports multiple portions at once
- Pre-seasoned surface is ready for cooking
- Reinforced ridges are designed to promote even heat distribution
- Detachable handles and grease trough aid handling and cleanup
Cons:- Large dimensions may not fit every grill
- Cast iron can be heavy to lift
- Takes more storage space than the GORGERILA or BIQetrae
Best for: Households that regularly cook large batches of burgers, pancakes, steak, or vegetables on a spacious gas or charcoal grill.
Not ideal for: Owners of smaller grills or anyone who wants a compact, easy-to-lift insert for occasional side dishes.
- Brand:Utheer
- Material:Cast iron
- Dimensions:25 × 16 inches
- Compatibility:Most gas and charcoal grills
- Surface:Pre-seasoned nonstick
- Support:Reinforced support ridges
- Handles:Detachable
- Grease management:Built-in grease trough
Our verdict“Choose the Utheer when your grill can accommodate its wide footprint and cooking capacity matters more than easy storage.”
BIQetrae 17 x 13-Inch Cast Iron Griddle for Gas Grills and Stoves
The BIQetrae’s raised sides make it a practical pick for cooks who want to keep chopped vegetables, eggs, or smaller foods from sliding off a flat plate. Its 17 x 13-inch footprint is more manageable than the Utheer’s 25 x 16-inch surface, while its removable handles help with lifting once cooking is done. A reinforced base and grease groove address two common concerns with grill inserts: uneven heating and excess drippings. Compared with the GORGERILA, the BIQetrae lists compatibility with many two- and three-burner gas grills, plus select named models, but that fit still depends on the exact grill dimensions. It also calls for oiling after cleaning and before storage, so it takes more ongoing care than the porcelain-coated Charbroil insert.
Pros:- Raised sides help contain food during cooking
- Grease groove helps manage drippings and reduce flare-up risk
- Removable handles make lifting easier
- Suitable for compatible grills and stoves
Cons:- Compatibility varies by grill model and cooking-area dimensions
- Requires oiling after cleaning and before storage
- Smaller cooking area than the Utheer
Best for: Owners of compatible two- or three-burner grills who cook small foods and value raised edges and removable handles.
Not ideal for: Buyers who want a maintenance-light coated insert or cannot verify that its 17 x 13-inch size fits their grill.
- Brand:BIQetrae
- Material:Cast iron
- Dimensions:17 × 13 inches
- Coating:Nonstick
- Compatible grills:Most 2- and 3-burner gas grills; select Weber, Char-Broil, and Nexgrill models
- Handles:Removable
- Sides:Raised
- Grease management:Grease groove
Our verdict“The BIQetrae suits buyers who want a mid-size, edged griddle and are willing to verify fit and maintain the surface.”
Weber Full-Size Carbon Steel Griddle Insert
This Weber insert is the strongest fit for buyers with one of the specified Weber grill models who want to convert the full cooking area, rather than place a smaller plate over part of the grates. Its pre-seasoned carbon steel surface is designed for even heat retention, and rimmed edges help contain food and reduce spills. Compared with the broad-compatibility GORGERILA, this is far less adaptable: it fits designated Spirit and Searwood models, with compatibility tied to grill type and, for some Spirit models, manufacturing year. Its full-size coverage also calls for storage space, and a storage bag is sold separately. For the right Weber owner, its matched fit and compatible grease management offer a more integrated setup than the Utheer or BIQetrae, but other grill owners should look elsewhere.
Pros:- Converts the full cooking surface of compatible grills
- Pre-seasoned carbon steel is ready to cook
- Designed for even heat retention
- Rimmed edges and compatible grease management help contain mess
Cons:- Fits only specified Weber Spirit and Searwood models
- Compatibility depends on grill type and, for some models, manufacturing year
- Storage bag is sold separately
Best for: Owners of compatible Weber Spirit or Searwood grills who want a full-surface insert with a model-specific fit.
Not ideal for: People with non-Weber grills, Weber models outside the listed fit range, or shoppers seeking a highly portable insert.
- Brand:Weber
- Material:Carbon steel
- Preparation:Pre-seasoned
- Compatible gas grills:Spirit 4-burner models manufactured since 2025; Spirit and Spirit II 3-burner models manufactured 2016–2024
- Other compatibility:Searwood pellet grills
- Model number:6787
- Warranty:2 years
- Included components:Weber Full Size Griddle
Our verdict“Choose this Weber insert if your exact grill is on the compatibility list and you want full-surface coverage rather than a universal plate.”
Universal Cast Iron Flat Top Griddle for Gas/Stove/Electric/Charcoal Grill, 23 x 16 in
This 23 x 16-inch cast-iron insert suits buyers who want one griddle for a gas grill, charcoal grill, oven, or stove. Its 5.8 mm cast iron is designed to hold heat and resist warping, a useful advantage for steady batches of burgers or breakfast food. The raised sides help keep smaller ingredients on the plate, while the handles make repositioning more practical than on a handle-free insert. Compared with the Hisencn 17 x 13-inch carbon-steel griddle, this model offers more cooking area and broader stated appliance compatibility, but it is also a larger, heavier piece to store and move. It requires seasoning before use and ongoing care to maintain its naturally nonstick surface. Check your grill grate dimensions and lid clearance before buying; “universal” does not guarantee a fit.
Pros:- Large 23 x 16-inch surface accommodates several foods at once.
- 5.8 mm cast iron is designed for heat retention and resistance to warping.
- Raised sides help contain food during cooking.
- Handles support lifting and repositioning.
Cons:- Requires seasoning and continuing cast-iron care.
- Large dimensions may not fit smaller grills or allow the lid to close.
- Cast-iron construction can be cumbersome to lift and store.
Best for: Grill owners who want a large cast-iron plate that can also be used on compatible stoves or in an oven.
Not ideal for: People with compact grills, limited storage, or a preference for a coated surface that does not need seasoning.
- Material:Cast iron
- Dimensions:23 x 16 x 2.6 inches
- Thickness:5.8 mm
- Shape:Rectangular
- Color:Black
- Stated compatibility:Gas, charcoal, electric, oven, and stove cooking surfaces
- Included components:One griddle plate
Our verdict“Choose this if you want a roomy, versatile cast-iron insert and have the grill space and storage to match.”
Hisencn 17 x 13 in Griddle for Gas Grill and Stove Top
The Hisencn’s 17 x 13-inch footprint makes it a more manageable choice than the larger 23- and 25-inch inserts in this group. That smaller surface can suit a three-burner grill or a buyer who wants to leave part of the grate open for direct-flame cooking, though the stated fit covers most 3–5 burner grills rather than every model. Its pre-seasoned carbon steel offers a ready-to-cook surface without relying on a synthetic nonstick coating, and the grease channel helps direct drippings away from the cooking area. Compared with the larger QuliMetal 25 x 16-inch griddle, this is easier to fit and store but provides less room for cooking a full meal in batches. Carbon steel still needs periodic reseasoning, and its weight can make handling less convenient.
Pros:- Compact 17 x 13-inch size is easier to fit and store than larger inserts.
- Pre-seasoned carbon steel provides a cooking surface without a synthetic coating.
- Raised sides and a grease channel help manage food and drippings.
- Stated compatibility covers many 3–5 burner grills and stovetops.
Cons:- The smaller surface limits how much food can cook at once.
- Fit may be unsuitable for smaller or unusually shaped grill grates.
- Requires periodic reseasoning and can be heavy to handle.
Best for: Owners of smaller or mid-size gas grills who want a compact flat top and are comfortable maintaining seasoned carbon steel.
Not ideal for: Cooks who need space for several servings at once, or anyone unwilling to check grate dimensions and maintain the seasoning.
- Brand:Hisencn
- Model number:CC172
- Material:Carbon steel
- Dimensions:17 x 13 inches
- Surface:Pre-seasoned
- Fit:Most 3–5 burner gas grills
- Other stated use:Stovetops
Our verdict“Pick the Hisencn if you want a relatively compact, pre-seasoned carbon-steel insert rather than the bigger cooking area of the QuliMetal.”
QuliMetal 25 x 16-Inch Nano-Ceramic Cast Iron Griddle for Gas Grills
QuliMetal pairs a large 25 x 16-inch surface with cast-iron construction, making it a candidate for cooks who want to prepare multiple items on one insert. Its nano-ceramic coating is described as PFOA- and PFAS-free and is intended to make food release and cleanup easier than on bare cast iron, which needs seasoning. A grease trough catches drippings, while a reinforced crossbar is intended to help resist warping. Compared with the Arribueno 23 x 16-inch ceramic-coated griddle, QuliMetal gives you more stated width but uses cast iron rather than carbon steel, so handling may be more demanding. The tradeoff is straightforward: a broad cooking zone takes up substantial grate and storage space, and a universal label cannot substitute for measuring your grill. Its listed maximum temperature is 550°F.
Pros:- Large 25 x 16-inch surface provides room for cooking multiple items.
- Nano-ceramic coating is designed to ease food release and cleanup.
- Grease trough helps collect drippings.
- Reinforced crossbar is intended to resist warping.
Cons:- Large footprint may not fit a grill or allow its lid to close.
- Cast iron can be cumbersome to lift and store.
- Listed maximum temperature is 550°F, which may limit use at higher temperatures.
Best for: Households that cook several foods at once and want a large coated cast-iron insert with a grease trough.
Not ideal for: Owners of compact grills or anyone who needs a light plate that is easy to lift and store.
- Brand:QuliMetal
- Material:Cast iron with nano-ceramic coating
- Dimensions:25 x 16 x 2.6 inches
- Maximum temperature:550°F
- Shape:Rectangular
- Color:Black
- Coating:PFOA/PFAS-free nano-ceramic
- Included components:Griddle
Our verdict“Choose QuliMetal for a large coated cast-iron cooking area, provided your grill can support its dimensions and weight.”
Arribueno 23 x 16 in Ceramic-Coated Griddle for Gas Grills
Arribueno’s practical distinction is its detachable handles: they can help with moving the plate and reduce the space handles occupy when storing it. The 23 x 16-inch carbon-steel body is smaller than the SHINESTAR 25.2 x 16.2-inch griddle, so it may be a better match for some three- or four-burner grills, though buyers still need to check the actual grate and lid clearance. Its ceramic nonstick surface, raised edges, and grease trough are aimed at easier cooking and better control of drippings. Unlike the Hisencn, it avoids the listed routine of maintaining a pre-seasoned steel surface, but the product details do not specify a maximum temperature or coating-care limits. The main tradeoff is fit uncertainty: compatibility is described broadly, not by exact grill models.
Pros:- Detachable handles aid transport and take up less space when removed.
- Ceramic nonstick coating is designed to simplify cooking and cleanup.
- Grease trough and raised edges help contain drippings and food.
- Carbon-steel construction gives it a smaller footprint than the 25-inch SHINESTAR.
Cons:- Fit needs to be checked against the grill or stovetop dimensions.
- No maximum cooking temperature is provided in the supplied specifications.
- At 23 x 16 inches, it may still be too large for compact grills.
Best for: Owners of compatible 3- or 4-burner grills who value detachable handles and a coated surface for simpler cleanup.
Not ideal for: Buyers seeking confirmed compatibility with a specific grill model or a stated high-temperature limit.
- Brand:Arribueno
- Model number:ABG-252316
- Material:Carbon steel
- Coating:Ceramic nonstick
- Dimensions:23 x 16 x 2.63 inches
- Shape:Rectangular
- Compatibility:Many 3- and 4-burner gas grills, some charcoal grills, and indoor gas stoves
- Included component:Detachable handle
Our verdict“Choose Arribueno if detachable handles and a coated 23-inch plate matter more to you than the larger surface of SHINESTAR.”
SHINESTAR 25 x 16 in Grill Griddle for Gas & Charcoal Grills, Carbon Steel
SHINESTAR offers the largest stated cooking surface here, at 25.2 x 16.2 inches, for buyers who want room to cook burgers, vegetables, and breakfast foods at the same time. Its reinforced carbon-steel body and ceramic coating aim to combine even heating with easier food release, while high sidewalls and a grease trough help contain food and drippings. Foldable handles make storage more practical than fixed handles, though the plate still weighs 17 pounds. Compared with the Arribueno 23 x 16-inch griddle, SHINESTAR provides more room and explicitly lists gas and charcoal compatibility, but it also requires a larger support area: at least 27.5 x 16.5 inches for proper support and lid closure. That fit requirement and weight make this a poor match for smaller grills or frequent lifting.
Pros:- 25.2 x 16.2-inch surface provides substantial cooking capacity.
- Ceramic nonstick coating is designed for easier food release and cleanup.
- High sidewalls and a grease trough help contain food and drippings.
- Foldable handles make storage and transport more manageable.
Cons:- Requires a cooking area of at least 27.5 x 16.5 inches for support and lid closure.
- At 17 pounds, it may be difficult to lift or move often.
- The large footprint can leave limited room for other grill cooking zones.
Best for: Cooks with a large gas or charcoal grill who want to prepare multiple foods at once and have room to store a 17-pound insert.
Not ideal for: Owners of compact grills, buyers who need a light or frequently moved plate, or anyone whose lid clearance is limited.
- Brand:SHINESTAR
- Material:Carbon steel with ceramic coating
- Cooking surface size:25.2 x 16.2 inches
- Item dimensions:25.2 x 16.22 x 2.76 inches
- Item weight:17 lb
- Color:Black
- Shape:Rectangular
- Compatible grills:Gas and charcoal
- Features:Foldable handles, grease trough, and high sidewalls
Our verdict“Pick SHINESTAR for maximum flat-top capacity if your grill meets its clearance requirements and you can manage its weight.”
Universal Cast Iron Griddle for Gas Grill 23″ X 16″
The 23 x 16-inch cooking area makes this a better fit for family meals than compact inserts such as the Unidanho 17 x 13-inch griddle: there is more room to cook several foods at once. Its cast-iron construction is designed to retain heat, while the reinforced base aims to resist warping under high temperatures. A grease groove helps channel drippings away from the cooking surface, and the matte-enamel finish is intended to reduce sticking. The tradeoff is its substantial 10.6 kg weight, which makes lifting and storage less convenient than with a smaller plate. “Universal” does not confirm a fit for every grill, so I would measure the grill surface before buying. This makes the most sense when capacity matters more than easy handling.
Pros:- Large 23 x 16-inch surface supports cooking several foods at once
- Cast iron is designed to retain heat
- Reinforced base is intended to resist warping
- Grease groove and matte-enamel surface address drippings and food sticking
Cons:- At 10.6 kg, it is cumbersome to lift and store
- Large dimensions may not fit smaller grills; compatibility should be checked
- Care instructions for the matte-enamel finish are not specified
Best for: Households cooking full outdoor meals or several ingredients at once on a grill with enough room for a 23 x 16-inch insert
Not ideal for: Owners of compact grills or anyone who needs a light, frequently moved griddle; its large footprint and 10.6 kg weight are less convenient
- Material:Cast iron
- Dimensions:23 x 16 x 3 inches
- Weight:10.6 kg
- Shape:Rectangular
- Color:Black
- Surface:Matte enamel
- Grease management:Grease groove
- Compatibility described:Most gas grills, charcoal grills, and gas stoves
Our verdict“Choose this large cast-iron insert for batch cooking if your grill can accommodate its footprint and you can manage its weight.”
Uniflasy Pre-Seasoned Nonstick Griddle for Gas Grills, 17 x 13 Inches
The nano-ceramic nonstick coating is the main reason to choose this 17 x 13-inch insert: it aims to make delicate foods and cleanup less troublesome than with the untreated cast iron of the BBQ Future 23 x 16-inch griddle, which calls for seasoning before first use. Raised sides help keep small ingredients on the plate, while the built-in grease trough gives drippings a route off the cooking area. Ventilation holes and side handles add practical details, but the smaller surface leaves less room for a full grill-load meal than the larger BBQ Future. There is also a product-data inconsistency: its material is described as both metal and cast iron. I would verify the material and measure the grill before buying, since compatibility is limited to suitable dimensions rather than a guaranteed universal fit.
Pros:- Nano-ceramic coating is designed to ease cooking and cleanup
- Raised sides help contain smaller foods
- Built-in grease trough channels drippings
- Side handles and ventilation holes add functional details
Cons:- Material description conflicts between metal and cast iron
- 17 x 13-inch surface is smaller than the 23 x 16-inch BBQ Future
- Fit depends on grill dimensions and model
Best for: Grill owners who cook vegetables, seafood, or other foods that benefit from a nonstick surface and want a more contained 17 x 13-inch insert
Not ideal for: Buyers who need a clearly specified material, a large batch-cooking surface, or a confirmed fit without measuring their grill
- Brand:Uniflasy
- Model:CC172
- Dimensions:17 x 13 x 2.6 inches
- Material:Listed as metal; product description also refers to cast iron
- Coating:Nano-ceramic nonstick
- Compatibility:Gas and charcoal grills; select Weber, Nexgrill, Char-Broil, Kenmore, and Camp Chef models
- Features:Raised sides, ventilation holes, built-in grease trough, side handles
- Included components:One griddle
Our verdict“Pick this when coating-led convenience matters more than a large cooking area, after confirming both the material and your grill’s dimensions.”
BBQ Future Universal Cast Iron Grill Griddle, 23 x 16 Inches, with Spatula Set
The BBQ Future pairs a 23 x 16-inch cast-iron surface with a three-piece spatula set, making it a convenient package for buyers setting up a grill-top cooking station. Like the Universal Cast Iron Griddle in this roundup, it offers room for multiple foods; its high walls and grease trough add containment around that broad surface. The included tools give it an edge over the Unidanho 17 x 13-inch griddle, which has a smaller footprint and no utensil set listed. That bundle does not remove the upkeep cast iron needs: the surface should be seasoned before first use and cared for to help prevent rust. The product is also a large, heavy-style insert without a listed weight, so I would check the grill dimensions and storage space before choosing it.
Pros:- 23 x 16-inch surface accommodates multiple foods
- Three-piece spatula set is included
- High walls and grease trough help contain food and drippings
- Listed for gas and electric grills, gas stoves, and outdoor burners
Cons:- Requires seasoning before first use

Weber Genesis II Porcelain-Enameled Cast Iron Griddle Insert
Unlike the universal plates in this group, the Weber 7599 is made to replace one grate on compatible Genesis II and Genesis II LX grills, giving owners of those models a more integrated fit. Its double-sided design switches between a flat cooking surface and grates, so it can handle griddle foods without giving up a grilling option. Porcelain-enameled cast iron retains and distributes heat, while the angled surface directs grease into a reservoir. That focused compatibility is also its main limitation: it does not fit 2022 or newer Genesis gas grills, and it is less adaptable than the BBQ Future insert for use across different grill types. Hand washing is recommended, so cleanup is not as hands-off as a coated plate may be. Check the exact grill generation before choosing it.
Pros:- Designed to replace one grate on specified Genesis II models
- Double-sided flat and grate surfaces offer two cooking styles
- Porcelain-enameled cast iron retains and distributes heat
- Angled surface directs grease into a reservoir
Cons:- Does not fit 2022 or newer Genesis gas grills
- Compatibility is limited to specified Genesis II and Genesis II LX grills
- Hand washing is recommended
Best for: Owners of compatible Genesis II or Genesis II LX 3-, 4-, or 6-burner grills who want a grate-replacing insert with both flat and gridded cooking surfaces
Not ideal for: Owners of 2022 or newer Genesis grills, other grill brands, or anyone who wants a portable universal insert or dishwasher-friendly care
- Brand:Weber
- Model:7599
- Material:Porcelain-enameled cast iron
- Dimensions:22 x 16 x 3 inches
- Weight:15 lb
- Maximum temperature:260 °C
- Compatibility:Genesis II and Genesis II LX 3-, 4-, and 6-burner grills
- Care:Hand wash
- Warranty:2 years
Our verdict“For a compatible Genesis II grill, this is the most integrated choice; owners of other or newer models should choose a universal insert instead.”
Unidanho Cast Iron Grill Griddle, 17 x 13 Inches
At 17 x 13 inches, the Unidanho is easier to size for smaller grills than the 23 x 16-inch Universal Cast Iron Griddle or BBQ Future, while still offering a cast-iron surface for grill-top meals. Its X-brace reinforced base is intended to resist warping, and the grease channel helps manage drippings; side handles support moving the plate. The tradeoff is the weight: at 6.47 kg, it is still a substantial piece of cookware despite its smaller footprint. Unlike the Uniflasy, it has no listed nonstick coating, so it should not be chosen on the promise of coating-led cleanup. The stated maximum temperature of 500 °C is unusually high relative to the Weber’s listed limit, so I would treat that figure as a product specification to verify rather than a reason alone to buy.
Pros:- More compact 17 x 13-inch footprint than the 23 x 16-inch plates
- Cast iron is designed to retain heat
- X-brace reinforced base is intended to resist warping
- Grease channel and side handles aid cooking and handling
Cons:- Weighs 6.47 kg, making frequent lifting less convenient
- No nonstick coating is listed
- Listed maximum temperature of 500 °C should be verified
Best for: Owners of smaller gas grills who prefer cast iron and want a reinforced insert with a grease channel and handles
Not ideal for: Anyone seeking a very light plate, a nonstick-coated surface, or a large area for cooking several meal components at once
- Brand:Unidanho
- Material:Cast iron
- Dimensions:13 x 17 x 3 inches
- Weight:6.47 kg
- Maximum temperature:500 °C, as listed
- Shape:Rectangular
- Color:Black
- Features:X-brace reinforced base, grease channel, side handles
Our verdict“Choose this compact cast-iron insert for a smaller grill if you accept the weight and prefer a reinforced, uncoated cooking surface.”
How We Picked
I ranked these inserts around the decision a gas-grill owner actually faces: will it fit, how much flat-top space does it provide, and how much care will it need? I compared listed dimensions, stated materials, coatings, and intended grill compatibility. A product-specific fit or design is more useful than a broad universal claim when it gives buyers clearer guidance, while larger formats earn attention for cooks who want more griddle area.
The order also reflects tradeoffs, not a claim that one material suits everyone. Surface area, handling, upkeep, and versatility all affect whether an insert will get regular use. Since the supplied product details do not establish head-to-head cooking results or grill-by-grill fit, I do not treat performance claims as verified; buyers should confirm dimensions and manufacturer guidance before ordering.

Factors to Consider When Choosing Plancha Griddle Insert For Gas Grill
Choosing a flat-top insert is less about finding the biggest plate and more about matching the plate to your grill, menu, and tolerance for upkeep. These factors can help narrow the options before you compare individual models.
Measure the Grill, Not Just the Insert
Measure the usable cooking grate from edge to edge and check whether the grill has a raised rim or unusual shape. Compare those measurements with the insert’s actual dimensions, leaving room for the plate to sit securely rather than balancing on the edges. A plate that covers the burner area too broadly may limit access to direct flame or interfere with the grill’s design. Check lid clearance as well, especially if you expect to close the lid while cooking. Universal compatibility describes a broad intended use, not a guarantee of fit for every grill model. When the maker provides model-specific fit guidance, use it as a stronger reference than the product title alone.
Choose Coverage Around Your Cooking Style
A full-width plate gives you room to cook several foods together, but it also removes more access to the original grates. A smaller insert can handle eggs, vegetables, or a side dish while leaving another zone open for food that benefits from direct grilling. Think about your usual group size and whether you cook an entire meal on the griddle or only a few items. More surface area is useful only when you have enough burner control to use it; a large plate over an uneven heat pattern may leave hot and cool areas. If you often switch between griddle cooking and open-grate grilling, a compact format can be the more practical choice.
Weigh Material Against Handling and Care
Cast iron and carbon steel are common choices in this lineup, but their weight and maintenance can affect everyday use. A heavy plate may sit steadily on the grill, yet lifting and storing it can be awkward, particularly when it spans most of the cooking area. Uncoated metal surfaces typically call for attentive drying and care to limit rust, while a coated surface has its own cleaning and utensil considerations. Check care instructions before buying rather than assuming every flat top can be treated like a grate. Consider where the insert will cool and be stored, too, since a large, heavy plate needs more room than a small one.
Understand What a Coating Changes
Ceramic or other nonstick-style coatings may appeal to cooks who want food release and a different cleanup routine, but the coating becomes part of the product’s long-term care equation. Follow the manufacturer’s guidance on utensils, cleaning tools, temperature limits, and seasoning rather than applying cast-iron habits by default. A coating can also make damage more consequential: scratches or surface wear may affect how the insert cooks and cleans. Uncoated cast iron and carbon steel avoid a factory coating but ask for more deliberate upkeep. Choose based on the care routine you will actually follow, not on a coating label alone.
Check Burner Layout and Heat Control
A flat plate changes how heat reaches food: the burners heat the metal first, and the metal spreads that heat across the cooking surface. The grill’s burner arrangement and control range can matter as much as the insert itself, especially with a broad plate. If your grill has distinct heat zones, a large insert may let you keep one side warmer than another, but results depend on the grill and plate combination. Avoid assuming that a wider insert automatically cooks more evenly. Match plate size to the area your grill can heat usefully, and plan to learn the plate’s hot spots before cooking a full meal on it.
Factor in Storage and What Comes in the Box
Before choosing a large format, decide where it will live between cookouts and how you will move it while cool. A 23- or 25-inch plate can provide useful cooking room but may be inconvenient if storage space is limited. Accessories can add convenience, as with the BBQ Future listing that includes a spatula set, though included tools should not outweigh fit and material in the decision. Confirm exactly what is included and how the insert is meant to rest on the grill. A manageable plate that is easy to store is often a better regular-use choice than a larger one that stays on a shelf.
Frequently Asked Questions
How do I know whether a universal griddle insert will fit my gas grill?
Measure the grill’s usable cooking surface and compare it with the insert’s listed dimensions, then check the manufacturer’s fit notes for your grill model. Confirm that the plate can rest securely without covering areas that must remain open or obstructing the lid. Also check the grill’s burner layout and any raised edges that could prevent the insert from sitting flat. “Universal” is not the same as model-specific fit. If the listing does not clarify a detail, ask the manufacturer before buying.
Should I get a compact insert or a full-size griddle plate?
Choose a compact insert if you want to griddle a few foods while keeping part of the grill available for direct cooking. A full-size plate makes more sense when you plan to cook most of a meal on a flat surface or need room for multiple servings at once. Large plates can be heavier to lift and take up more storage space, so account for handling as well as cooking area. The best size is the one your grill can heat and you can store comfortably. For mixed cooking, a smaller insert can be more flexible.
Is cast iron or carbon steel the better choice for a gas grill insert?
Neither material is automatically better for every grill owner; fit, weight, and care habits matter. Cast iron is common among the compact and large inserts in this roundup, while the Weber Full-Size and SHINESTAR options are carbon steel. Compare the maker’s instructions for handling, cleaning, and storage, since product construction can shape care needs. Pay particular attention to weight if you will remove the plate often. Choose the material and size you can maintain and move safely.
Do I need a coated griddle insert, or should I choose an uncoated one?
A coated option may appeal if you prefer a surface marketed for easier food release, but it requires care that protects the coating. Follow the product’s guidance on utensils, cleaning, and heat rather than treating it like bare metal. Uncoated cast iron or carbon steel avoids a factory coating, but usually calls for attention to drying and surface care. Decide based on the upkeep you are willing to do, not just the coating claim. The QuliMetal and Arribueno listings are the coated alternatives in this group.
Can I use a griddle insert and the grill’s regular grates at the same time?
That depends on the insert’s footprint and how it sits on your grill. A compact option such as the Charbroil 12-inch insert is more likely to leave grate area available than a full-width plate, but the exact fit still depends on your grill. Check whether the insert blocks burners or prevents the lid from closing before planning a split-surface setup. Do not assume a partial-width insert leaves a usable direct-grill zone without checking your grate dimensions. Follow the grill and insert makers’ instructions for safe placement.
Conclusion
For most buyers seeking a broad, grill-specific flat-top setup, I would start with the Weber Full-Size Carbon Steel Griddle Insert as the best overall choice, subject to checking compatibility with the grill model. The best value direction is a 17 x 13-inch cast-iron option such as GORGERILA or Hisencn when compact coverage matters more than full-grill cooking. For a premium-style full-width option, compare the Weber Full-Size Carbon Steel Insert with the Weber Genesis II Porcelain-Enameled Cast Iron Insert based on grill fit and care preferences. Beginners who want to keep some grates open may prefer the Charbroil 12-inch insert for its smaller footprint. For coated-surface buyers, look at QuliMetal or Arribueno; for broad coverage, compare the 23- and 25-inch plates only after measuring the grill. My final rule is simple: confirm fit first, then choose the largest surface you will comfortably handle and maintain.
