In a rice cooking method using a microwave oven, when a rice cooking start signal is inputted, a weight of a mixture of rice and water within a heating chamber is sensed. According to the sensed weight of the mixture, a heating time period T1, T2 of a moisture absorbing process for soaking the rice is computed, and during this heating time period, a preset microwave heating signal P1, P2 is supplied to the heating chamber to avoid premature boiling. Successively, when a heating process for boiling the rice and the water is executed, a preset microwave heating signal P3, P4 is supplied to the heating chamber, and the supply of this heating signal is continued only up to a time T3, T4 that the sensed humidity within the heating chamber reaches a preset humidity limit value G1, G2. A heating time period T5, T6 of a thorough cooking process is calculated in dependence on the heating time periods of the moisture absorbing process and the heating process, and during this heating time period, a preset microwave heating signal P5, P6 is supplied to the heating chamber. According to this method, good rice cooking is automatically executed even if the mixing ratio of the rice and water is not optimum, and a separate weight signal need not be inputted from a keyboard. <IMAGE> |
