A combination convection/microwave oven in which a food product is cooked by microwave energy and by a heated airflow provided by a thermal energy source and a blower. The oven is capable of cooking food in a microwave reflective pan. Microwave energy enters the oven below the pan and is guided to a spacing between the pan and oven sides and then reflected by the sides and top of the oven to the food product in the pan. The heated airflow is laminar with an upper layer and a lower layer. The pan is positioned at about the interface of the two layers so that the upper layer is incident on the food product and the lower layer is incident on the bottom of the pan.

1. A combination oven for cooking a food product with microwave energy and hot air comprising:a cooking chamber and a plenum disposed in a side wall of said cooking chamber such that said plenum is in fluid communication with said cooking chamber via an air egress port area and an air ingress port area disposed in a side wall thereof; a source of energy, which is capable of introducing said microwave energy into said cooking chamber; a food rack capable of holding said food product within said cooking chamber; and means for heating and circulating an airflow through said cooking chamber and said plenum to develop a laminar airflow pattern in said cooking chamber, wherein said laminar airflow pattern has a first laminar air stream that is above said food rack and a second laminar air stream that is below said food rack, wherein at least one of said first and second laminar air streams has first and second loops that share a common path toward said air egress port area, and wherein said ingress port area comprises an upper port area and a lower port area that are separated from one another such that said first and second laminar air streams circulate substantially through said upper and lower port areas, respectively.
