Ingredients

Scale

Main Ingredients

  • 1 pound ground beef (85% lean)
  • 1 large onion, thinly sliced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon soy sauce
  • 4 hamburger buns
  • 1 cup shredded Swiss cheese
  • Fresh parsley (optional for garnish)

Instructions

  1. Heat oil: Heat olive oil in a large skillet over medium heat until shimmering to prepare for cooking the onions.
  2. Caramelize onions: Add the thinly sliced onions and cook for 10-12 minutes, stirring occasionally, until they become golden and caramelized, building the dish’s rich flavor base.
  3. Add garlic: Stir in minced garlic and cook for an additional 1-2 minutes until fragrant to enhance the aroma of the mixture.
  4. Cook beef: Add ground beef to the skillet and cook until fully browned, breaking it apart with a spatula to ensure even cooking.
  5. Season mixture: Drain excess fat from the beef, then stir in Worcestershire sauce and soy sauce along with thyme, salt, and pepper to taste, combining all flavors well.
  6. Simmer: Let the beef mixture simmer gently for 5 minutes allowing the flavors to meld beautifully.
  7. Toast buns: While simmering, lightly toast the hamburger buns until golden brown to add a crispy texture.
  8. Assemble sandwiches: Scoop the beef and onion mixture onto the bottom half of each toasted bun, top with shredded Swiss cheese, and place the top bun over to crown the sandwich.
  9. Garnish and serve: Garnish with chopped fresh parsley if desired and serve immediately for best taste and texture.

Notes

  • Caramelizing onions slowly is key to developing the deep, rich flavor in this recipe.
  • Use lean ground beef (85% lean) to balance flavor and reduce excess fat.
  • To melt the Swiss cheese better, you can place assembled sandwiches under a broiler for 1-2 minutes if desired.
  • Fresh parsley adds a nice touch of color and freshness but can be omitted if unavailable.
  • Toast buns just before assembling for optimal texture and to prevent sogginess.
