The main lid 3 is opened to place food in the cooking area 20 of the inner pot 2. Then, the water supply pump 8 is started, the first steam control valve 71 is opened, the water in the water storage tank 8 enters the steam generation unit 61 to form steam, the steam enters the steam delivery pipeline 62 and is finally sprayed into the cooking area 20 through the cooking steam nozzle 63 to perform steam cooking on food. When the amount of steam in the cooking area 20 reaches a preset value, the water supply pump 8 and the first heating unit 4 stop working, the first steam control valve 71 is closed, and the second heating unit 5 is opened to bake and heat the food placed in the cooking area 20. And after the heating is carried out for a preset time or the preset temperature is reached, the second heating unit 5 stops working, and the first heating unit 4 starts heating. When the first heating unit 4 reaches a preset temperature, the water supply pump 8 is activated, the first steam control valve 71 is opened, and cooking steam is supplied to the food in the cooking area 20 again. And circulating the steps until the preset cooking time or the preset circulation times are met, stopping the work of the water supply pump 8 and the first heating unit 4, closing the first steam control valve 71, and opening the second heating unit 5 to bake the food for the last time so as to embrittle the skin of the food. The food cooked by steaming and baking not only has crisp surface, but also keeps fresh and tender inside without too dry and hard, and has good taste.
