A casserole is a kind of large, deep pan or bowl used for cooking a variety of dishes in the oven; it is also a category of foods cooked in such a vessel. To distinguish the two uses, the pan can be called a "casserole dish" or "casserole pan", whereas the food is simply "a casserole". The same pan is often used both for cooking and for serving.

Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware.
