This mushroom Swiss burger recipe is a delicious and flavorful twist on the classic cheeseburger. Saute sliced mushrooms in butter until tender, then set aside. Season ground beef with salt and pepper, form into patties, and cook on a grill or stovetop. Top with Swiss cheese and the sauteed mushrooms. Serve on a toasted bun with lettuce, tomato, onion, and your favorite condiments for a tasty and satisfying meal.
