Something went wrong. Our team is working on it. Original recipe (1X) yields 6 servings 6 hamburger buns, split 1/4 cup butter 8 ounces sliced mushrooms 2 onions, thinly sliced salt and freshly ground black pepper 2 pounds ground beef 1 (1 ounce) packet dry onion soup mix 12 slices havarti cheese 6 tablespoons mayonnaise Directions Preheat a large skillet over medium heat. Place hamburger bun halves, cut-sides down, in the hot skillet until lightly toasted, 2 to 3 minutes. Remove toasted buns to a plate. Preheat an outdoor grill for medium heat. Heat butter in a large saucepan over medium heat on the grill. Add mushrooms and onions; season with salt and black pepper and cook and stir until mushrooms are lightly browned, about 20 minutes. Meanwhile, mix ground beef and onion soup mix in a bowl using your hands. Form mixture into 6 hamburger patties. Lightly oil grill grates. Grill burgers for about 5 minutes, then flip and grill to your desired doneness. A meat thermometer inserted near the center of patties should read 180 degrees F (82 degrees C). Remove burgers from heat to rest for 5 minutes. Spread each bun with 1 tablespoon mayonnaise, and add burgers; divide mushrooms and onions between burgers to serve.
