How to Season Granite Grill Cooking Slabs

A granite grill cooking slab, which is similar to cast iron, distributes heat more evenly over the surface of your food as it cooks on the grill. Unlike cast iron, a granite cooking slab never rusts, and you can use it on the grill, in the oven and in the microwave. Each time you use your stone, you need to season it by coating it with oil and preheating it on the grill. Once you use your granite cooking slab, you might never grill without it again.

Wash the granite grill cooking slab with soap and hot water before use. Brush the cooking surface of the granite cooking slab with an even coating of olive oil, and place it on a cold grill or oven.

Preheat the grill to warm the granite stone. Heat the stone for at least 15 minutes.

Lay the food directly on top of the granite cooking slab once the grill or oven completely heats.

Let the stone cool completely before washing with hot, soapy water.
