A shelf assembly (16) is mounted in a rotatable manner within the main oven body enclosure (12) between lateral side walls thereof, whereby the shelf assembly (16) will hold various foods to be cooked. A driver mechanism (18) is mounted on the main oven body enclosure (12) for rotating the shelf assembly (16). A gas burner system (20) is within the main oven body enclosure (12) below the shelf assembly (16). A cooking access system (22) is on the main oven body enclosure (12) in front of the shelf assembly (16), so that a person can open the cooking access system (22) to safely reach the food on the shelf assembly (16). A forced air circulation system (24) is on the main oven body enclosure (12).
