Nordic Ware Nonstick pans are made of pure aluminum, which conducts heat quickly and evenly for beautifully browned foods, no matter what you bake, sweet or savory. The brilliant nonstick coating is made without PFAS and is great for easy release and cleanup. The dual-color pans have a light gray interior so they don't over-brown your foods and a colorful blue exterior to complement any kitchen! The 4-piece Natural Aluminum pan set includes a variety of pans to fit your baking and cooking needs: a half sheet, a baking pan, a muffin pan, and a round. Bake sheet pan meals, dessert bars, cookies, savory egg bakes, enchiladas, roasted meats and vegetables, cakes, cupcakes, or muffins! Once you use them, you'll understand why aluminum sheet pans are an indispensable classic in both professional and home kitchens alike. Proudly made by Nordic Ware, a family-owned company.
