Abstract: A non-recirculating convection oven includes an upper housing portion defining a food heating chamber. The upper housing portion includes a removable lid, to access the food heating chamber. At least one exhaust air outlet allows air to exhaust to an exterior of the upper housing portion. A food supporting tray is positioned in the food heating chamber, with the tray including a solid food supporting portion. A lower housing portion below the upper housing portion includes an intake air inlet for intake air, and a blower assembly for heating the intake air and delivering it to the food heating chamber wherein the intake air enters the lower housing portion at the intake air inlet, and the intake air is then heated to a temperature of at least 250° F. The heated air exits the food heating chamber at the at least one exhaust air outlet, wherein none of the heated air is recirculated within the oven to the blower assembly.
