Super durable, lighter than cast iron and oh, that gorgeous unexpected slate blue. Used separately or together, our slate blue baking sheet and cooling rack are part of our exclusive bakeware collection that takes its cue from professional kitchens. Made of carbon steel—an alloy of 99% iron and 1% carbon that's nearly indestructible—the baking sheet and rack feature a double layer of silicone-based non-stick coating that ensures easy release and quick cleanup. The baking sheet's superior heat conductivity promotes even cooking and consistent results, while the cooling rack elevates food for better air circulation. Used together, the pan and rack are ideal for fat-reduced bacon, dry-roasted tomatoes and crispy-crust flatbreads as well as for catching drips from drizzled frosting on cakes and cookies.
