Ingredients

Scale

Beef Mixture

  • 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
  • 1 teaspoon dried thyme
  • Salt and pepper to taste

Assembly

  • 4 hamburger buns
  • 1 cup shredded Swiss cheese
  • Fresh parsley, chopped (optional for garnish)

Instructions

  1. Caramelize the Onions: Heat the olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook for 10-12 minutes, stirring frequently until they are golden and caramelized, bringing out their natural sweetness.
  2. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes, allowing the garlic to become fragrant but not brown.
  3. Cook the Beef: Add the ground beef to the skillet and cook until fully browned, breaking it apart with a spatula to ensure it cooks evenly.
  4. Season the Mixture: Drain any excess fat from the skillet. Then stir in Worcestershire sauce, soy sauce, dried thyme, salt, and pepper. Mix well to combine all the flavors.
  5. Simmer: Reduce the heat and let the mixture simmer for about 5 minutes so the flavors meld together beautifully.
  6. Toast the Buns: While the beef mixture is simmering, toast the hamburger buns until lightly golden and crisp to provide a sturdy base for the filling.
  7. Assemble the Sloppy Joes: Spoon the beef and onion mixture generously onto the bottom half of each toasted bun. Top each with a portion of shredded Swiss cheese, then place the top bun over the filling.
  8. Garnish and Serve: Optionally sprinkle freshly chopped parsley on top for a fresh, colorful finish before serving immediately for the best taste and texture.

Notes

  • Use 85% lean ground beef for the best balance of flavor and fat.
  • Caramelizing onions takes time but adds deep flavor; don’t rush this step.
  • Substitute Swiss cheese with Gruyère or mozzarella for a different flavor profile.
  • For a gluten-free option, use gluten-free hamburger buns.
  • Leftover filling can be refrigerated for up to 3 days and reheated before serving.
