A pellet barbecue configured to recirculate exhaust gas, allowing for the reduction of oxygen in the cooking chamber. The pellet barbecue is configured with an exhaust gas recirculation system, and an angled bottom fire pot. The electric gas recirculation fan pulls gases from a gas recirculation channel, and blows it onto the angled bottom fire pot. The gas recirculation channel is equipped with a movable mixer flap to control how much of the gas pulled by the gas recirculation fan is exhaust gas or outside air. The pellet barbecue controller monitors the conditions in the cooking chamber, and controls the gas recirculation fan speed and positioning of the mixer flap to maintain a desired temperature, while optimizing the concentration of wood taste compounds from the pellets in the cooking chamber.
