A baking steel is a flat slab of steel that sits on an oven rack and holds a lot of heat. Bakers use it under pizza, flatbread and loaves because steel moves heat into dough quickly. The main choices are thickness, footprint and weight, since these slabs are heavy.
The six steels below range from a 1/4 inch slab to a 3/8 inch slab that weighs more than 30 pounds. Sizes, weights and finish come from each product’s listing page. We have not used these steels ourselves. Conductivity and bake-time claims are the makers’ own.
