  2. Step 2: Stir in minced garlic and cook for an additional 1-2 minutes.
  3. Step 3: Add ground beef to the skillet, cooking until fully browned while breaking it apart as it cooks.
  4. Step 4: Drain excess fat and mix in Worcestershire sauce, soy sauce, thyme, salt, and pepper. Simmer for 5 minutes.

Tips & Variations

  • Use caramelized yellow or sweet onions for deeper flavor and natural sweetness.
  • Swap ground beef for ground turkey or plant-based meat for a lighter or vegetarian option.
  • Add a splash of dry white wine while caramelizing onions for an extra layer of flavor.
  • Top with crispy fried onions for added crunch and texture.

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 the sandwiches. Buns are best fresh but can be stored separately in a sealed bag for 1-2 days.

How to Serve

The image shows a silver pan filled with cooked ground beef mixed with small pieces of green bell pepper, creating a textured base layer with mixed brown and green colors. On top of this beef and pepper mixture, there are uneven circles of melted white cheese that have some slight bubbles and golden brown spots, adding a smooth creamy layer with a bit of shine. A wooden spatula is partially inside the pan, stirring the mixture on the right side, showing some meat and cheese stuck lightly to it. The pan rests on a white marbled surface with a blue cloth in the background and some green herbs peeking from the top left corner. photo taken with an iphone --ar 4:5 --v 7

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

  1. 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.
  2. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes to release its aroma and flavor into the onions.
  3. 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.
  4. 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.
  5. Toast Buns: Toast the chicken hamburger buns until they are golden brown and slightly crisp, enhancing their flavor and texture.
  6. 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.
