Swiss Diamond is changing the way home chefs cook every day. The Nonstick Square Casserole with Lid is no exception. Its square shape allows for a larger 5.3-qt cooking capacity, as well as easily fitting next to other pans in the oven. This pan is perfect for that big Thanksgiving meal where you already have enough to wash: take this casserole dish from the stovetop to the oven (safe up to 500 F) to the dinner table for serving. Once dinner is done, Swiss Diamond's patented diamond-reinforced nonstick coating helps with the cleanup too. Simply use warm water and soap and the pan comes clean with ease. Use the included heat-tempered lid to control the moisture level in and out of the oven. Heavy-duty cast aluminum construction guarantees heat will be distributed evenly and efficiently in all corners of this pan.
