A cooker includes: a main body; a container inside the main body; a stirring body having a blade for stirring an object to be cooked in the container and a magnet at a position facing an inner bottom part of the container; a magnetic field generator inside the main body and configured to generate a rotating magnetic field so that a rotational force of the rotating magnetic field acts on the magnet; and a controller inside the main body and configured to control the magnetic field generator so that: (i) a direction of rotation of the rotating magnetic field is switched between a forward rotation direction and a reverse rotation direction that is reverse to the forward rotation direction; and (ii) a number M of rotations in the reverse rotation direction is less than a number N of rotations in the forward rotation direction.
