Half Sheet is a kitchen must-have. Designed around professional grade specifications but made for home use, and exceeds expectations in the home. The durable, natural aluminum construction bakes evenly and browns uniformly, while the light color prevents overbrowning. The generous edge also makes getting these pans in and out of the oven a cinch. The Half Sheet is an essential tool in the kitchen you will use in a variety of ways from sheet pan dinners, to baked goods to food prep. Set includes two half sheets!
