Caramelized Onion-Bacon Burgers Recipe

Place 1/3 cup barbecue sauce in a small bowl. Crumble beef over barbecue sauce and mix well. Shape into four patties. In a small skillet, cook bacon over medium heat until crisp. Remove to paper towels; drain. In another skillet, saute onion in 2 tablespoons butter until softened. Reduce heat to medium-low; cook, stirring occasionally, for 20-25 minutes or until golden brown. Spread buns with remaining butter; set aside. Grill burgers, covered, over medium heat or broil 4 in. from the heat for 5-7 minutes on each side or until a thermometer reads 160 ° and juices run clear. Top with cheese. Grill 1 minute longer or until cheese is melted. Place buns, cut side down, on grill for 1-2 minutes or until toasted. Spread buns with barbecue sauce; serve burgers on buns with onion and bacon.
