A stainless steel griddle plate can give your gas grill a flat cooking surface for foods that might fall through the grates, from eggs and pancakes to chopped vegetables and burgers. The right choice depends on your grill’s usable space, how much cooking area you need, and whether you want a simple plate or a more specialized setup. Our top pick is the onlyfire, while the other options include a smaller stainless steel plate, a coated model, a cast-iron alternative, and a complete grill with an integrated griddle.

Our Picks: Best Stainless Steel Griddle Plate For Gas Grill reviews
1. onlyfire Universal Stainless Steel Griddle: Best Overall
The onlyfire is a large rectangular stainless steel insert designed for gas and charcoal grills. Its 25-by-16-inch surface gives you space to cook several kinds of food at once, while raised sides help contain ingredients when you flip or stir them. That makes it a practical pick for breakfasts, burgers, sandwiches, and chopped vegetables.
The plate has handles on both sides, a grease groove around the edges, and a wavy underside intended to support airflow beneath the cooking surface. The listing also highlights removable handles, which can help with moving or storing the plate. At this size, check your grill’s cooking area and lid clearance before buying; a universal label does not guarantee a fit on every grill.
Its main trade-off is the broad, substantial format. It offers more cooking space than the WHISTLER plate, but will take up more room and may be less convenient to store. The grease groove helps manage drippings, though you will still need to handle and clean a hot, greasy cooking surface with care.
Pros:
- Large 25-by-16-inch cooking surface
- Raised sides help keep food from sliding off
- Grease groove helps channel excess oil
- Side handles make the plate easier to move
Cons:
- May be too large for smaller grills or limited storage space
- Check grill clearance and dimensions before ordering
Verdict: Choose the onlyfire if you want a roomy stainless steel griddle insert with useful containment and grease-management features.
2. WHISTLER Stainless Steel Universal Griddle: Compact Alternative
The WHISTLER is a straightforward stainless steel flat-top plate for outdoor cooking. It is intended for gas and charcoal grills and can handle foods such as eggs, potatoes, quesadillas, grilled cheese, and steak. Its listed cooking area is around 250 square inches, making it a smaller option than the 25-by-16-inch onlyfire.
There is an important sizing detail to check: the product description gives dimensions of 18.9 by 13.25 inches, while the specifications list 18.9 by 15.82 inches. Because those figures do not match, confirm the plate’s actual dimensions with the seller and measure your grill before purchasing. The listed height is 0.78 inches.
This model may suit you if you want a simpler plate without the larger onlyfire’s raised-side and grease-groove features. Its compact footprint could be easier to accommodate on some grills, but the conflicting width information makes fit-checking especially important.
Pros:
- Stainless steel cooking surface
- Designed for outdoor gas and charcoal grills
- Useful for a range of breakfast and cookout foods
Cons:
- Listed width is inconsistent across the product information
- Does not list raised sides or a grease groove
Verdict: Consider the WHISTLER for a basic stainless steel plate, but verify its dimensions before deciding whether it will fit your grill.
3. Uniflasy Nonstick Stainless Steel Griddle: Coated Surface Option
The Uniflasy is another large-format option, measuring 25 by 16 inches. Its product description says it is made from stainless steel and has a nano-ceramic nonstick coating. It also describes raised sides, a grease trough, detachable handles, and ventilation openings beneath the plate.
The coating sets it apart from the plain stainless steel options. A coated surface may appeal if easy food release is high on your list, but the supplied product information does not explain specific care limits or how the coating should be maintained. Read the seller’s care instructions before use, and avoid assuming that every utensil or cleaning method is suitable for a coated surface.
The claimed size and accessory features look similar to the onlyfire’s, so fit should be checked in the same way: measure the grill’s usable area and confirm lid clearance. This is a reasonable option if you specifically want a coated surface, while the onlyfire is the simpler choice if you prefer an uncoated stainless steel cooking face.
Pros:
- Large 25-by-16-inch surface
- Product description claims a nano-ceramic nonstick coating
- Raised sides and a grease trough help contain food and drippings
- Detachable handles are listed for moving and storage
Cons:
- Care and coating limitations are not detailed in the supplied information
- Large footprint may not suit every grill
Verdict: Pick the Uniflasy if you want a large griddle with a claimed nonstick coating, and confirm care guidance and grill fit before buying.
4. NutriChef Reversible Cast Iron Griddle: Flat and Ridged Sides
The NutriChef is not stainless steel, but it is a useful alternative if you want one surface for griddle cooking and another for grill marks. This 18-by-10-inch cast-iron plate has a flat side for foods such as pancakes and a ridged side for meats and vegetables. It can also fit over two burners on suitable stovetops.
Cast iron is heavier than the stainless steel inserts in this guide, so consider your grill’s size and how you plan to lift and store the plate. The product is pre-seasoned, and its instructions describe seasoning to build a natural cooking surface. A silicone oven mitt is included for handling, but you should still use appropriate heat protection when moving hot cookware.
Some users find the weight reassuring, while others may find it difficult to manage on a small grill. Unlike the larger stainless steel plates, this one has a smaller cooking area and a ridged side, so it is best for shoppers who value versatility over a broad, all-flat surface.
Pros:
- Reversible flat and ridged cooking surfaces
- Can be used on a grill or over two suitable stovetop burners
- Pre-seasoned cast iron construction
- Includes a silicone oven mitt
Cons:
- Heavier than the stainless steel plate options
- Smaller cooking surface than the 25-by-16-inch inserts
Verdict: Choose the NutriChef if you want reversible cast iron and do not mind a heavier, smaller plate; skip it if stainless steel is a must.
5. La Bolata Four-Burner Grill: Complete Grill with Integrated Griddle
This La Bolata product is a complete propane gas grill, not a standalone stainless steel griddle plate. It includes cast-iron grill grates and a dedicated cast-iron griddle plate, along with four main burners, a side burner, side shelves, a thermometer, and a removable grease tray. It is relevant if you are shopping for a full grilling station rather than an insert for an existing grill.
The product information describes separate cooking zones for grilling and griddle cooking, which could be useful when preparing different foods at once. Its grease tray and removable cup are intended to simplify cleanup. Some users find a full grill setup dependable for family meals, though assembly time and the space required are worth considering.
Because this is a larger purchase with a built-in cooking setup, it is not a direct alternative to the portable plates above. It also does not meet a strict requirement for a stainless steel griddle surface: the included griddle is described as cast iron.
Pros:
- Includes a dedicated cast-iron griddle plate and grill grates
- Four main burners plus a side burner
- Removable grease tray and cup
- Side shelves and built-in thermometer are included
Cons:
- Not a standalone griddle insert
- Griddle plate is cast iron, not stainless steel
Verdict: Consider this grill only if you want a complete propane grill with an integrated cast-iron griddle, rather than a stainless steel plate for your current grill.
How to Choose a Stainless Steel Griddle Plate for a Gas Grill
Measure the usable cooking area
Measure the grill surface where the plate will sit, not just the outside width of the grill. Compare those measurements with the plate’s length and width, and leave room for the grill’s edges and any parts that must stay uncovered. Also check whether the lid closes with the plate in place. A large plate can offer more cooking space, but it may not work well on a compact grill.
Check the listed dimensions carefully
Product dimensions can be easy to misread, especially when a listing gives different figures in separate sections. The WHISTLER listing, for example, provides conflicting width measurements. Confirm the seller’s current specifications before ordering, and contact the seller if the size is still unclear.
Choose the surface style that fits your cooking
A flat plate is useful for foods that need a continuous surface, such as eggs, pancakes, chopped vegetables, and sandwiches. Raised sides can help keep ingredients on the plate while you turn or stir them. A ridged, reversible model offers grill marks as well as a flat side, but cast iron is a different material from stainless steel and needs different care.
Consider grease handling and cleanup
A groove or trough can guide excess grease toward the edges rather than letting it spread across the cooking surface. It does not eliminate the need to manage drippings, so plan how you will empty or wipe the channel safely. If you choose a coated plate, check its care instructions before using metal tools or abrasive cleaners.
Think about handles, weight, and storage
Handles can make a plate easier to place, remove, and store, but they do not make it safe to handle while hot without suitable heat protection. Consider the plate’s overall size and weight alongside your storage space and how often you plan to move it. A large plate may offer more room for cooking but can be more awkward to store than a smaller one.
Look for clear material and care information
If stainless steel is important to you, make sure the cooking surface is actually described as stainless steel. Some products combine stainless steel with a coating, while others use cast iron or include a cast-iron plate as part of a larger grill. Check the seller’s instructions for heating, cleaning, and storing the specific product you choose.
Frequently Asked Questions
Will a universal griddle plate fit any gas grill?
No. “Universal” does not guarantee a fit on every grill. Measure the usable cooking area, compare it with the plate’s dimensions, and check that the grill lid and other parts have enough clearance.
What can you cook on a stainless steel griddle plate?
A flat griddle surface can be used for foods such as pancakes, eggs, bacon, burgers, sandwiches, seafood, and vegetables. The exact foods you can cook depend on the plate’s size and the cooking space available on your grill.
Is stainless steel the same as cast iron?
No. Stainless steel and cast iron are different materials with different weight and care needs. The onlyfire, WHISTLER, and Uniflasy are described as stainless steel options; the NutriChef and the La Bolata grill’s included griddle plate are cast iron.
Do raised sides matter on a grill griddle?
Raised sides can help keep small or chopped foods from sliding off while you stir or flip them. They may be useful for mixed ingredients, though the height and design vary by product.
Does a grease groove mean cleanup is automatic?
No. A grease groove can help channel excess oil, but you will still need to clean the plate and safely manage any collected grease. Follow the product’s care instructions and allow the surface to cool as directed before cleaning.
Which option is best if I want a stainless steel griddle?
The onlyfire is the strongest all-around choice in this group if you want a large, uncoated stainless steel plate with raised sides and a grease groove. The WHISTLER is a simpler alternative, but confirm its dimensions because the listing provides conflicting width figures.
Is the La Bolata grill a griddle plate?
No. It is a complete propane gas grill that includes a cast-iron griddle plate. Choose it if you want a full grill setup, not if you only need a stainless steel insert for a grill you already own.
Final Recommendation
For most shoppers looking for a stainless steel griddle plate for a gas grill, the onlyfire is the best place to start. Its 25-by-16-inch surface, raised sides, handles, and grease groove make it a versatile choice, provided it fits your grill. Choose the WHISTLER for a simpler plate after confirming its measurements, or consider the Uniflasy if you specifically want a coated surface. The NutriChef and La Bolata are alternatives for shoppers open to cast iron, not stainless steel.
