A smoker oven that includes a housing having an internal cavity having a top portion, a mid-portion, and a lower portion. The internal cavity houses a support frame that has at least one generally horizontal support surface for supporting and rotating a jerky rack. The jerky rack holds food items in sheet form, such as strips of jerky, at an angle to the horizontal support surface, so that upon rotation of the jerky rack the food items in sheet form cause an agitation and motion of the air within the cavity to produce even heating of the food items and cause fluids released by the food item to flow off of the food item.
