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
- Step 1: Heat the olive oil in a skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for 10-12 minutes until they are caramelized and golden brown.
- Step 2: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
- Step 3: Add the ground beef to the skillet. Cook it fully until browned, breaking it apart as it cooks to ensure even browning.
- Step 4: Drain any excess fat from the skillet. Then mix in Worcestershire sauce, soy sauce, dried thyme, salt, and pepper. Let the mixture simmer gently for 5 minutes to blend the flavors.
- Step 5: Toast the chicken hamburger buns until they are golden brown and slightly crisp.
- Step 6: Assemble the sandwiches by spooning the beef mixture onto the bottom half of each bun. Generously top with shredded Swiss cheese, then place the top bun on.
Tips & Variations
- For extra depth, add a splash of beef broth during simmering to make the mixture juicy.
- Swap Swiss cheese for Gruyère for a more authentic French onion flavor.
- Caramelizing the onions slowly over low heat will create a sweeter, richer taste.
- Serve with crispy pickles or a side salad to balance the richness.
Storage
Store any leftover beef mixture in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave before assembling fresh sandwiches. The buns are best toasted right before serving to maintain crispness.
