SIRLOIN CHEESEBURGER RECIPES

Steps:

• Combine all sauce ingredients in small bowl; set aside. 
• Gently combine ground beef. (Do not overmix.) Divide into 4 equal portions. Gently shape into 4 1/2-inch patties, each about 3/4 inch thick. Place onto parchment-lined platter. Create indent in top of each patty by pressing 3 fingers into center. (The indent should be about 1/4 inch deep and 3 inches wide.) Season both sides of each patty with salt and pepper. Refrigerate until grill is ready. 
• Heat one side of gas grill on medium or charcoal grill until coals are ash white. Place coals to one side in charcoal grill.
• Place burgers onto grill away from heat, indent-side up. Close grill; cook 15-16 minutes or until internal temperature of center of burger reaches 145°F.
• Meanwhile, cook bacon in 10-inch skillet over medium heat until sizzling and almost cooked. Add mushrooms and soy sauce. Cook, stirring often, until mushrooms are golden brown. Set aside; keep warm.
• Transfer burgers to heated side of grill. Cook 1-2 minutes or until bottom side is charred. Flip burgers; top each burger with 2 slices cheese. Continue cooking until cheese is melted and thermometer inserted into center reaches 160°F or until desired doneness. 
• Spread bottom of each bun with about 1/2 tablespoon of sauce, place burger on bun, top with about 1 tablespoon sauce, mushrooms, bacon and 2 onion rings.

Steps:

• Heat grill or grill pan to medium-high heat. Heat oven to 400°. Wrap hamburger buns in foil and place in lower part of oven. Bake 10 minutes.
• Meanwhile, in a large bowl mix together the ground beef, Worcestershire, garlic powder, salt, Italian seasoning and pepper. Shape into 6 patties and grill 3 minutes. Flip burgers over and grill another 2 minutes. Top with cheese slices and cook 1 minute more for medium.
