The invention discloses an electric cooking pot and a control method thereof. The electric cooking pot comprises an inner pot, an upper cover, a main heating module, an auxiliary heating module, a power supply module and a control module. The main heating module is used for conducting resonance heating on the inner pot. The auxiliary heating module is arranged on the upper cover and is used for heating the upper cover. The power supply module is used for converting alternating currents provided by an alternating current power source into direct currents so as to supply power to the main heating module and the auxiliary heating module. The control module is connected with the main heating module and the auxiliary heating module and controls the main heating module and the auxiliary heating module to conduct heating in turns after the electric cooking pot enters the heat preservation stage. Thus, the main heating module and the auxiliary heating module are controlled to conduct heating in turns, the heat preservation effect can be achieved, the phenomenon that the water content of rice is reduced or even charring happens is avoided, the taste of rice is improved, condensate water of the upper cover can be vaporized and is prevented from flowing into the rice, and the taste of the rice is ensured.
