The Swiss Diamond nonstick roaster is a versatile piece of bakeware that cleans up in a snap. The patented Swiss Diamond nonstick coating browns food for a savory exterior, creating the rich pan drippings needed for flavorful sauces. Thick, cast-aluminum construction prevents burning on the bottom and transfers heat evenly around the entire piece of meat. To braise, use the included heat-tempered glass lid with adjustable steam vent.
