A portable baking oven for a pizza or other food item includes a food item heating plate, a base having a heating chamber, and a top cover having a moisture vent and a heat reflector structure extending across the inside of said top cover. When placed on said base, the top cover forms a baking chamber above the heating plate. Heat produced in the base's heating chamber circulates up through air passageways in the base into the baking chamber above the food item heating plate. This circulated heat is reflected back down toward the food item heating plate by the top cover's heat reflecting structure to accelerate baking of the top of a food item placed on the heating plate. The top cover's moisture vent can be located above the heat reflector structure in the top cover, and openings can be provided in the heat reflector structure which allow moisture emitted by a food item being baked in the oven to pass through the reflector structure and out through the top cover moisture vent.
