A multifunctional cookware is disclosed. A side of a chassis is provided with a vessel, so that a single cookware can fry foods with the chassis and cook soups with the vessel. The vessel is covered with a lid, further changing the vessel into a vacuum cooker to simmer the foods. Furthermore, a steaming pan is disposed between the vessel and the lid, so that steam produced by heating up liquid in the vessel can steam the foods on the steaming pan, turning the vessel into a steamer. In the present invention, a frying pan, a stockpot, a vacuum cooker and a steamer are combined into one unit, allowing a single cookware to have multiple purposes at a same time, which increases convenience in using the cookware and reduces the space required to accommodate plural cookware.
