Ingredients

  • 2 tablespoons butter (or a mixture of butter and olive oil)
  • 2 large yellow onions, thinly sliced
  • 2 cloves garlic, minced
  • 1 lb (≈ 450 g) ground beef (80/20 preferred)
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon all-purpose flour
  • 1/2 cup beef broth
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 4 buns (hamburger, brioche, or preferred type)
  • 4 slices Swiss, Gruyère, or provolone cheese

Instructions

  1. Melt the butter (or butter and olive oil) in a large skillet over medium-low heat.
  2. Add the sliced onions and cook slowly, stirring occasionally, until deeply golden and caramelized, about 15–20 minutes.
  3. Stir in the minced garlic and thyme and cook for 1–2 minutes until fragrant.
  4. Push the onions to one side of the skillet and add the ground beef. Cook until no pink remains, breaking up the meat as it browns.
  5. Sprinkle flour over the beef and onions, stirring well, and cook for 1 minute to eliminate the raw flour taste.
  6. Pour in the beef broth and Worcestershire sauce, stirring to combine and scraping up browned bits from the pan.
  7. Simmer for 4–6 minutes until the mixture thickens into a saucy consistency. Season with salt and pepper to taste.
  8. Toast the buns under a broiler or in a buttered skillet until lightly crisp.
  9. Spoon the beef-onion mixture onto the bottom half of each bun, top with a slice of cheese to melt, then cover with the top bun.
  10. Serve immediately while warm.

Notes

  • For extra richness, deglaze the pan with a splash of white wine or sherry before adding broth.
  • Add sautéed mushrooms for more depth of flavor.
  • Use provolone, Swiss, or Gruyère cheese for different flavor profiles.
  • To avoid soggy buns, always toast them before assembling.
  • The filling can be refrigerated up to 3 days or frozen up to 2 months.
