Abstract: A device (22) for heating a food product (P). The device (22) including an oven enclosure (52) at lest one magnetron for emitting microwave energy and a microwave energy focusing device (68, 70, 72) associated with at least one magnetron (56, 58, 60, 62, 64 and 66) and adapted to focus microwave energy towards the food product. The magnetron(s) is/are disposed external the enclosure (52) and the microwave energy focusing device(s) is/are disposed internal the enclosure (52). Also disclosed is a food product support device (116) of a substantially truncated conical external shape with a first larger base surface (118) adapted to be positioned adjacent the base of the oven enclosure and a second smaller supporting surface (120) adapted to support a food product (P) in a position vertically displaced from the base of the oven enclosure for heating and a sloping side surface (122) extending between the base and support surfaces.
