Disclosed herein is a cooking appliance including a communicator configured to perform communication with a terminal, an input unit configured to receive information from a user, and a controller configured to, when information on time until which remote control using the terminal is available is received via at least one of the communicator and the input unit, control the communication with the terminal. According to the present disclosure, by allowing a user to set a time at which a remote control mode is automatically cancelled after cooking is finished, the remote control is available during a time set by the user even after cooking is finished, and thus the usability of the remote control mode can be improved. According to the present disclosure, by limiting performance time of the remote control mode to be within a preset amount of time and limiting an infinite input of a remote control command into a terminal while the remote control mode is activated, a network error can be prevented, and erroneous operation of a cooking appliance due to hacking can be prevented.
