The invention provides a temperature control method for a cooking device, and the cooking device. The cooking device comprises an induction cooker, a pan, and a pan cover state detection device. The bottom of a panel of the induction cooker is provided with a first temperature measurement device, and the cover of the pan is provided with a second temperature measurement device. The method comprises the steps: judging whether the cover of the pane is moved away or not: controlling the heating power of the induction cooker according to a first temperature signal collected from the first temperature measurement device if the cover of the pan is moved away, or else controlling the heating power of the induction cooker according to a second temperature signal collected from the second temperature measurement device. According to the technical scheme of the invention, the first temperature control signal or the second temperature control signal is selected for temperature control through combining with the state of the cover of the pan, and the temperature control precision of the induction cooker can be improved.
