Abstract
A device for microwave heating with inversion has a base and a cover defining a heating chamber. Both the base and the cover include a susceptor heatable by microwave energy and the cover includes an aperture to vent steam. With a food product in the heating chamber, the device is placed in a microwave oven resting on the base. During an initial heating period, the lower surface of the food product is browned or crisped due to conduction and steam escapes from the heating chamber via the aperture. After the initial heating period, the device in inverted and the food product comes into contact with the cover. The device is placed in the microwave oven resting on the cover during a secondary heating period in which the food product is heated further, and the upper surface of the food product is browned or crisped due to conduction.
