A method for controlling a cooking apparatus, comprising:

• determining whether a cooking starting signal is input;
• determining whether an automatic keep warm function is selected;
• if it is determined that the automatic keep warm function is selected, cooking food at a normal cooking temperature for a first cooking time;
• if the first cooking time passes, cooking the food in a residual heat cooking mode for a second cooking time and setting a temperature of a cooking chamber to be a keep warm temperature when the cooking of the food is completed at expiration of the second cooking time;
• and
• keeping the cooking chamber at the keep warm temperature.

A cooking apparatus having an automatic keep warm function, comprising:

• a heating source to heat a cooking chamber;
• a temperature sensor to measure a temperature of the cooking chamber;
• an automatic keep warm setting unit to selectively set an automatic keep warm function by receiving input from a user by way of an input unit;
• and
• a control unit, which is coupled to the heating source, the temperature sensor, and the automatic keep warm setting unit,
• wherein the control unit controls the heating source to cook food at a normal cooking temperature for a first cooking time,
• wherein the control unit controls the heating source to cook the food in a residual heat cooking mode, in which the food is cooked by residual heat of the heating source and at a residual heat cooking temperature which is lower than the normal cooking temperature, for a second cooking time, and
• wherein the control unit controls the heating source to set the temperature of the cooking chamber to a keep warm temperature after the second cooking time is completed to keep the food warm.
