ABSTRACT OF THE DISCLOSURE An automatic cooking apparatus and method for a microwave oven for discriminating the kind of food, to be cooked, on the basis of calculation of specific dielectric constant and dielectric power factor of the food by one-touch of the user and performing automatic cooking of the food according to the discriminated kind thereof. The apparatus comprises a microwave energy sensor for sensing the remaining microwave energy other than microwave energy absorbed into the food in a heating chamber. An electrical signal corresponding to the sensed microwave energy is generated in a microwave energy detection circuit, which then supplies its output signal to a control section. Also included therein is a weight sensor for sensing the weight of the food. An electrical signal corresponding to the sensed weight is generated in a weight detection circuit, which then supplies the weight signal to the control section. The control section calculates the specific dielectric constant and dielectric power factor of the food in response to a plurality of key signals outputted from a keyboard, the weight sense signal and the microwave energy sense signal, determines a heating time period of the food in accordance with the calculated results and controls the automatic cooking of the food in accordance with the determined heating time period of the food. 31
