Abstract: An oven for heating food and associated components and methods. The oven includes a food heating compartment bounding a food holding space for holding food to be heated. The food holding space has an open top. A bottom wall of the food heating compartment supports food in the food holding space and has gas flow inlets. A gas supply plenum is disposed below the food holding space and is in fluid communication with the food holding space via the gas flow inlets. A gas supply duct defines a gas supply passageway disposed below and fluidly coupled to the gas supply plenum. A heater heats the gas as the gas flows through the gas supply passageway. A blower blows the gas through the gas supply passageway, into the gas supply plenum and through the gas flow inlets into the food holding space for heating the food.
