Abstract
An apparatus and a method of controlling a microwave oven includes performing a first heating until detection values of a humidity sensor reach a reference value, wherein the humidity sensor senses humidity of water vapor discharged from a cooking chamber. A second heating is performed, lower than the first heating, after the detection values reach the reference value using an output power from a magnetron. A surrounding humidity condition of the microwave oven is determined. The reference value of the first heating is reset so as to cook food appropriately according to the determined humidity condition.
