Ingredients
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
- Caramelize Onions: In a skillet, heat olive oil over medium heat. Add the sliced onions and cook for 10-12 minutes until they are golden brown and caramelized, stirring occasionally to prevent burning.
- Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes to release its aroma and flavor into the onions.
- Brown the Beef: Add the ground beef to the skillet. Cook over medium heat until fully browned, breaking it apart with a spatula as it cooks to ensure even cooking and no large chunks remain.
- Season and Simmer: Drain any excess fat from the skillet. Mix in Worcestershire sauce, soy sauce, dried thyme, and season with salt and pepper. Stir well and let it simmer for 5 minutes so the flavors blend together.
- Toast Buns: Toast the chicken hamburger buns until they are golden brown and slightly crisp, enhancing their flavor and texture.
- Assemble Sloppy Joes: Place the beef and onion mixture generously on the bottom halves of the toasted buns, top with shredded Swiss cheese while the mixture is still warm so it slightly melts, then cover with the top halves of the buns to serve.
Notes
- You can substitute Swiss cheese with Gruyere or mozzarella for a different flavor profile.
- For a spicier version, add a pinch of cayenne pepper or hot sauce to the beef mixture.
- Use beef buns or any favorite sandwich rolls if chicken hamburger buns are not available.
- To make it gluten-free, swap the buns for gluten-free bread or lettuce wraps.
- Leftover beef mixture can be stored in an airtight container in the refrigerator for up to 3 days.
