Ingredients

Scale

Main Ingredients

  • 1 pound ground beef
  • 1 large onion, sliced
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon soy sauce
  • 1 teaspoon dried thyme
  • Salt and pepper to taste
  • 4 chicken hamburger buns
  • 1 cup shredded Swiss cheese

Instructions

  1. Caramelize Onions: In a skillet, heat the olive oil over medium heat. Add the sliced onions and cook them slowly for 10-12 minutes until they turn golden brown and caramelized, stirring occasionally to prevent burning.
  2. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant, making sure not to burn the garlic.
  3. Cook Ground Beef: Add the ground beef to the skillet with the onions and garlic. Break up the meat with a spoon or spatula, cooking until fully browned and no pink remains.
  4. Season and Simmer: Drain any excess fat from the skillet. Then mix in Worcestershire sauce, soy sauce, dried thyme, and season with salt and pepper to taste. Simmer the mixture for 5 minutes to let the flavors meld.
  5. Toast Buns: While the beef mixture simmers, toast the chicken hamburger buns until they are golden brown and slightly crisp.
  6. Assemble Sandwiches: Spoon the French onion beef mixture onto the bottom half of each toasted bun. Generously top with shredded Swiss cheese, then cover with the top bun. Serve immediately while warm.

Notes

  • Caramelizing onions slowly over medium heat is key to developing deep, sweet flavor without burning.
  • Use lean ground beef to reduce excess fat and grease in the dish.
  • Swiss cheese adds a nutty richness that complements the savory beef and onions perfectly.
  • For a twist, you can substitute the chicken buns with whole wheat or brioche buns.
  • Add a handful of fresh thyme leaves for a brighter herb flavor if desired.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days; reheat gently before serving.
