DESC: Preparing your favorite soups and casseroles is a breeze with All-Clad's Cop-R-Chef covered casserole pan. Designed with a classic shape, the casserole is unsurpassed in aesthetics and in quality. Each piece from the Cop-R-Chef line is constructed form three layers of metal; a finely polished copper exterior, pure aluminum core and 18/10 stainless steel interior. The heavy gauge copper outer layer is an excellent conductor of heat, and combined with the aluminum core, disperses heat evenly across the base to heat the stainless steel interior that creates the ideal cooking surface that is easy to clean. The two looped, stay-cool side handles are riveted to the side of the pot for extra strength and durability, and helps prevent burns.
