onlyfire 18" x 12.5" Stainless Steel Flat Top Griddle Insert — Universal Grill Insert, 200+ sq in Nonstick Surface

The onlyfire 18"×12.5" stainless steel flat top griddle insert converts most gas grills into a smooth, easy-to-clean cooktop for pancakes, burgers, and seared vegetables.

This compact griddle gives you more usable surface area and more consistent searing than direct grate cooking while fitting into a wide range of gas grills. Built from stainless steel with welded cross bracing, it resists warping and moves heat more evenly across its 200+ square inches of cooking space. Removable handles, a grease trough, and a non-stick finish make day-to-day use and cleanup straightforward so you spend more time enjoying food and less time fussing with equipment.

How will this griddle change my grilling routine?

Swapping the standard grill grate for this flat-top insert expands the types of foods you can prepare and reduces flare-ups from dripping fat. The flat surface is ideal for breakfast foods and delicate items that would otherwise fall through grates.

• Over 200 square inches of continuous cooking area for multiple items at once.
• Sidewalls keep ingredients on the griddle while flipping and turning.
• Grease trough diverts drippings to reduce flare-ups and messy pans.

How durable and heat-stable is the stainless steel design?

The plate uses stainless steel construction with welded cross bracing to minimize flex and promote even heat distribution. This structure stands up to high grill temperatures and repeated use without significant warping.

• Welded cross bracing for structural stability and flatter cooking surface.
• Stainless steel resists corrosion and holds its appearance over time.
• Designed to sit directly on standard grill supports for reliable contact with heat sources.

What features make cooking and cleanup easier?

The griddle arrives with a non-stick finish that cuts down on food adhesion and simplifies washing. Removable handles and a wrench are included so you can install, remove, or tighten the unit quickly and store it when not in use.

• Non-stick surface reduces residue and speeds cleanup with a quick wipe.
• Two removable handles and one wrench for secure installation and easy transport.
• Grease trough channels drippings into a single collection area for disposal.

Will this insert fit my grill and how big is the cooking surface?

The griddle measures 18" wide by 12.5" deep with a 2.7" high sidewall, providing just over 200 square inches of usable space. Its universal sizing is intended to fit most gas grills that can accept a flat insert of similar dimensions, but checking your grill's internal measurements is recommended before purchasing.

• Exterior dimensions: 18" W x 12.5" D x 2.7" H.
• Offers 200+ square inches of continuous cooking surface.
• Compatible with many standard gas grills—verify interior width and depth first.

Who is this for: Home cooks and grill enthusiasts who want the flexibility to cook breakfast, delicate seafood, stir-fry, or multiple small items at once without changing pans constantly. It's particularly useful for people who want a durable, easy-to-clean surface that improves heat distribution and reduces flare-ups when using a gas grill.
