Bake, roast and fry to perfection with Viking Nonstick Baking Sheet.

This unique construction provides the strength and durability of baking with steel with the added conductivity of aluminum for exceptional heat distribution. Each sheet is reinforced with a solid steel frame around the entire outer edge of the pan. The steel frame gives each baking sheet stability, making it easy to take in and out of the oven while preventing warping.
