This NutriChef reversible griddle gives shoppers comparing cast iron griddles for gas grills two cooking surfaces in one 18 x 10-inch plate. Use the flat side for pancakes and other griddle foods, or flip to the ridged side for grill marks and a design that helps keep excess oil away from food.

How We Picked These Cast Iron Griddles for Gas Grills

We focused on griddles designed to sit on or replace part of a gas grill’s cooking surface, then compared the factors that matter most outdoors: dimensions, cooking area, material, surface design, seasoning or coating, reversibility, portability, and compatibility with common grill setups. The selection includes large flat tops for entertaining, compact options for smaller grills, and reversible plates for cooks who want both searing ridges and a smooth surface.

Because product specifications and grill dimensions can vary, always verify measurements, weight capacity, and burner clearance before ordering. A griddle should sit steadily without blocking necessary ventilation or creating unsafe contact with the grill lid.

Quick Comparison

• Large cooking areas: The 23-by-16-inch and 25-by-16-inch models are suited to family meals and batch cooking.
• Compact versatility: Smaller 14-by-16-inch, 17-by-13-inch, and 18-by-10-inch griddles are easier to handle and fit more grills.
• Two cooking surfaces: Reversible designs offer a smooth griddle side and a ridged grill side.
• Low-fuss setup: Pre-seasoned surfaces are ready for initial use but still benefit from regular oiling and proper drying.
• Alternative coatings: Ceramic or other nontraditional finishes may simplify release and cleanup, but follow the manufacturer’s utensil and temperature guidance.

Key Buying Factors for Cast Iron Griddles for Gas Grills

Size and Grill Fit

Measure the grill grate area, not just the exterior lid. Leave room for heat circulation and confirm that the plate will rest flat on the grates. Large griddles maximize output but are heavier and harder to store.

Flat, Ridged, or Reversible Surface

A fully flat surface is best for eggs, pancakes, chopped vegetables, and smash burgers. Ridges create sear marks and allow some fat to drain. Reversible models provide both functions but may require more careful handling when flipping or cleaning.

Heat Distribution and Grease Management

Cast iron retains heat well, which helps maintain temperatures when cold food is added. Preheat gradually rather than using maximum flame immediately. Grease channels, raised edges, and a drip area can help reduce spills, but a griddle still needs monitoring during high-fat cooking.

Seasoning, Coatings, and Care

Traditional cast iron develops a durable seasoning layer with repeated oiling and cooking. Avoid soaking it for long periods, dry it immediately, and apply a thin coat of oil after cleaning. Coated surfaces may need gentler tools and different care instructions, so follow the included manual.

Who Should Buy Which Cast Iron Griddles for Gas Grills?

Choose a large 23-by-16-inch or 25-by-16-inch griddle if you regularly cook for several people or want to prepare a complete breakfast or burger batch at once. Choose a medium 17-by-13-inch or 18-by-10-inch model for smaller grills, couples, weeknight meals, or easier lifting and storage. Choose a reversible griddle if you want one accessory for both flat-top cooking and grill-marked foods. Choose a pre-seasoned traditional cast iron model if heat retention and long-term durability matter most. Consider a ceramic-coated option if easier food release is a priority and you are willing to follow more specific care requirements.
