Step by step preparation 


  • 1 lb ground beef
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 4 large yellow onions, sliced
  • 4 slices Swiss cheese
  • 4 hamburger buns
  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon balsamic vinegar
  • 1/4 cup mayonnaise
  • 1 tablespoon dijon mustard


  1. In a bowl, mix together the ground beef, salt, pepper, garlic powder, and onion powder. Divide into 4 equal portions and shape into patties.
  2. Heat a large skillet over medium heat and add the butter and olive oil. Add the sliced onions and cook, stirring frequently, until caramelized and soft, about 20-25 minutes.
  3. In a separate pan, cook the hamburger patties until desired doneness. Top each patty with a slice of Swiss cheese and let it melt.
  4. In a small bowl, mix together the Worcestershire sauce, balsamic vinegar, mayonnaise, and dijon mustard to create the tangy sauce.
  5. Toast the hamburger buns and spread the tangy sauce on the top and bottom buns.
  6. Assemble the burgers by placing the patty on the bottom bun, topped with caramelized onions and the top bun.
  7. Serve and enjoy!

Note: You can also grill the burgers for a smoky flavor, or add additional toppings of your choice, such as lettuce, tomato, and pickles.
