Abstract

A method of controlling a microwave oven, in which the microwave oven includes a cooking chamber for containing food therein, a cooling fan which circulates air, a magnetron which generates microwaves and a humidity sensor which senses humidity of the cooking chamber. Cooking instruction(s) may be preset or set manually by a user. A first cooking operation is performed while preventing water from boiling off/to overflow by controlling an output power of the magnetron according to the set cooking instruction(s). A time required to perform a second cooking operation is set based on a time required to perform the first cooking operation. The second cooking operation is performed for the second cooking time while steam boiling the food.
