Abstract: An improved food oven and method of preparing food is disclosed characterized by a double-oven compartment structure with each compartment having multiple infrared heating rod arrays and a smoker unit adapted to prepare food disposed within the compartment. Operation of the heating rod arrays and smoker units are monitored by a novel electronic control system which permits independent baking, broiling, barbecuing, smoking and hold-warming of foods disposed within each compartment. The compartments further incorporate a unique vent system which automatically generates a convectional airflow through each of the compartments to reduce isolated temperature gradients within the compartments and effectuate a generally uniform preparation of food.
