A barbecue oven having an internal firewall separating a cooking chamber and a fire chamber. The firewall has a generally arcuate shape that forms an upwardly tapered duct connecting the fire chamber to the cooking chamber along an interior wall. As configured, the cooking chamber has a generally elliptical shape that promotes the recirculating of the heat and smoke within the cooking chamber. The constricted throat of the aperture creates an accelerated current of heat and smoke directed into the cooking chamber. The heat and smoke is directed up the rear wall, then passes across the top of the cooking chamber, down the front, and is then entrained in the current from the fire chamber. Thereafter, the heat and smoke exit the cooking chamber through portals opening into exhaust ducts contained within the sidewalls. Electric heating elements are placed adjacent to an elevated, elongated vessel containing the solid fuel such as wood or charcoal. The heating elements heat the solid fuel until the fuel begins to smolder. Once the fuel begins to smolder, a blower forces air through the solid fuel to create ignition of the fuel.
