The invention relates to a method for preparing food, particularly in an aircraft, comprising of placing the food in a preparation space of an oven and heating the preparation space, wherein the outer side of the oven is cooled during the preparation. Cooling air can be forced for this purpose along the outer surface of the oven. This cooling air can also be forced through the oven, along the electronics present therein.The invention further relates to an oven, in particular for use in an aircraft, comprising a preparation space and means for heating the preparation space, and means for cooling the outer side of the oven. These cooling means can be adapted to force cooling air along the outer surface of the oven, and can in addition be adapted to force the cooling air through or along an electronics compartment in the oven.
