How does the design improve cooking performance?

Grillflame redesigned the plate to increase the actual usable surface by removing oversized outer tabs that can reduce cooking area on some originals. The plate has a sunken cooking well that keeps vegetables and smaller items from sliding off, plus a built-in oil drain that channels grease away from food for easier cleanup. The thick cast iron construction provides even heat distribution and strong heat retention for better searing and steady temperature control.

• Sunken center prevents food from falling off
• Oil drain outlet channels grease away from the cooking surface
• Thick cast iron for steady heat and improved searing
• Edge profile maximizes usable cooking area

How do I care for and maintain this cast iron griddle?

Cast iron performs best when pre-seasoned and kept dry between uses. After cooking, wipe the surface clean, use hot water and a brush for stuck-on bits, dry thoroughly, then apply a thin coating of cooking oil to prevent rust. Routine re-seasoning and avoiding soaking will prolong the griddle's life and preserve a natural nonstick surface.

• Clean with hot water and a stiff brush; avoid soap when possible
• Dry immediately and heat briefly to remove moisture
• Apply a light coat of oil after each use to maintain seasoning
• Store in a dry place or indoors to prevent corrosion

What can I cook on this griddle and when is it most useful?

The flat cast iron surface makes this insert versatile for foods that would otherwise slip through grill grates. It’s ideal for small items, delicate proteins and large-batch breakfasts — anything from chopped vegetables and shrimp to pancakes, thin-sliced meats and burgers. The solid top also helps create even browning and convenient one-surface meals for families or gatherings.

• Great for vegetables, seafood, pork belly, and thin cuts
• Perfect for breakfast items: eggs, bacon, pancakes
• Useful for sauté-style dishes and stir-fry on the grill
• Helps when cooking many small pieces that fall through grates
