Nordic Ware Naturals® sheet pans are made of pure, uncoated aluminum, which conducts heat quickly and evenly for beautifully browned foods, no matter what you bake, sweet or savory. These pans are free of all coatings to bake natural, healthy foods, and they're great for baking XL portions of sheet pan meals, dessert bars, cookies, and roasted meat and vegetables. These pans maximize the size of a standard oven so you can fit more on one pan, and this set includes a convenient lid for storing your baked goods or prepped foods, which makes for easy storing and transportation and helps keep foods fresh longer. Pans clean up fast, and once you use them, you'll understand why uncoated aluminum sheet pans are an indispensable classic in both professional and home kitchens alike. Proudly made by Nordic Ware, a family-owned company.
