The invention provides a cooking device which comprises a box body forming a shell outside the cooking device, an inner container arranged in the box body, a frying
barrel arranged in the box body and located on one side of the inner container, a
vacuum pumping module used for pumping air and an oil box arranged at the bottom of the frying
barrel, and the frying
barrel comprises a barrel body and a first oil outlet formed in the bottom of the barrel body; the first oil outlet is communicated with the oil box, and is provided with an oil
control switch for controlling the communication of the frying cavity and the oil box, a pressure relief channel for communicating the frying cavity and air, and a pressure relief switch arranged in the pressure relief channel. In the
cooking process, the vacuumizing module is controlled to exhaust air in the frying cavity; after cooking is finished, firstly, an oil
control switch is controlled to be turned on, so that oil in the frying cavity flows into an oil box through a first oil outlet; and then the pressure relief switch is controlled to be turned on to relieve the pressure of the frying cavity, so that the influence on the taste of the food materials due to re-
oil absorption of the food materials after pressure relief is avoided.
