onlyfire 23" x 16" Stainless Steel Flat Top Griddle Insert — Universal Grill Insert, Even-Heat, Removable Handles

The onlyfire 23" x 16" stainless steel flat top griddle insert turns most larger gas grills into a flat-top cooking surface for evenly cooked breakfasts, seared sandwiches, and grill-top vegetables.

This heavy-duty griddle is engineered as a universal insert for grills with ample cooking area, offering a corrosion-resistant stainless-steel surface, integrated grease management, and a ventilation-backed design for consistent heat across the plate. Designed for both backyard cooks and mobile chefs, it combines a quick clean finish with detachable handles for compact storage.

How does the griddle achieve even heating across the cooking surface?

The underside features a wavy hollow pattern that channels heat and airflow to reduce hot spots and produce a more uniform surface temperature. This structural ventilation helps with steady cooking from edge to edge, so pancakes, burgers, and vegetables finish at the same rate.

• Wavy hollow underside promotes airflow and balanced heat distribution.
• Full stainless-steel plate conducts heat efficiently without warping.
• Raised sidewalls help retain heat and keep food on the surface.

Will this griddle fit my grill and how easy is it to store?

The 23" x 16" footprint is sized to work as a universal insert for most grills with a larger cooking area, while still being compact enough for transport. Detachable handles let you remove the sides for stacked storage or to slip the griddle into tighter spaces.

• 23 inches wide by 16 inches deep fits many full-size gas grills and open-fire setups.
• Removable side handles reduce overall width for easier storage and stacking.
• Flat, low-profile design slides into cabinets or grill storage racks.

How does the design simplify cooking and cleanup?

A sloped grease trough channels drippings away from the cooking surface to reduce flare-ups and speed cleanup. The stainless-steel finish wipes clean, resists staining, and stands up to repeated outdoor use without bending.

• Integrated grease trough collects oils for safer, cleaner grilling.
• Raised sidewalls make flipping and turning foods easier and neater.
• 100% food-grade stainless steel is corrosion-resistant and easy to maintain.

What kinds of foods and recipes benefit most from this flat top insert?

The flat top is ideal for foods that need an even contact surface — think breakfast items, smashed burgers, fajitas, stir-fried vegetables, and grilled sandwiches. Because the surface spreads heat uniformly, delicate foods like eggs and fish can be cooked gently while thicker items get reliable sear marks.

• Pancakes, eggs, and breakfast hashes that need broad, flat heat.
• Smashed burgers and seared sandwiches that require even contact.
• Vegetables and stir-fries that benefit from quick, even cooking.

Who is this for: The onlyfire 23" x 16" stainless-steel flat top griddle insert is aimed at backyard grillers, food-truck operators, and anyone who wants to expand a gas grill's versatility without buying a dedicated griddle. If you need a durable, easy-to-clean surface that fits into larger grills, provides consistent heat, and stores compactly thanks to removable handles, this insert is a practical upgrade for casual cooks and pros alike.
