Abstract: There is disclosed a multi-piece potable oven having a base plate, an oven body, a cover, and any of a skillet, "mess tray", steamer, or funnel lid. The base plate has a circular bottom portion and an upwardly extending frusto-conical opening at the center. The oven body has an upwardly extending cylindrical sidewall and a substantially flat bottom with an upwardly extending frusto-conical opening at the center thereof which is adapted to fit on the upwardly extending frusto-conical opening of the base plate. The skillet is placed over the oven body for frying or broiling. The "mess tray" is placed over the oven body when additional space is desired for baking, roasting, and general heating. The steamer is placed over the oven body when vegetables or seafood are to be steamed. The funnel lid covers the upwardly extending frusto-conical opening at the center of the oven body when the portable oven is used for steaming or popping corn.
