Ingredients
Beef Mixture
- 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
Assembly
- 4 chicken hamburger buns
- 1 cup shredded Swiss cheese
Instructions
- Caramelize Onions: In a skillet, heat olive oil over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for 10-12 minutes until they become golden brown and caramelized, developing sweetness and depth of flavor.
- Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes to release its aroma, taking care not to burn it.
- Brown Ground Beef: Add the ground beef to the skillet with the onions and garlic. Cook thoroughly, breaking the meat apart with a spatula until it is fully browned and no longer pink.
- Season and Simmer: Drain any excess fat from the skillet. Then add Worcestershire sauce, soy sauce, dried thyme, salt, and pepper to the beef mixture. Stir well and let it simmer gently for 5 minutes to allow the flavors to meld.
- Toast Buns: While the beef simmers, toast the chicken hamburger buns until they are golden brown to add a crisp texture and enhance flavor.
- Assemble Sloppy Joes: Spoon the beef mixture generously onto the bottom halves of the toasted buns. Top each with shredded Swiss cheese so it begins to melt from the warmth of the meat. Cover with the top halves of the buns and serve immediately.
Notes
- Use low-fat ground beef or turkey for a leaner version.
- Caramelizing onions slowly is key for the best flavor—don’t rush this step.
- Swiss cheese can be substituted with Gruyère or mozzarella for different flavor profiles.
- Consider serving with a side of pickles or coleslaw for added crunch and acidity.
- Leftover beef mixture can be stored in the refrigerator for up to 3 days.
