Ingredients You’ll Need

  • 2 cloves garlic, minced

  • 1 tablespoon olive oil

  • 1 teaspoon Worcestershire sauce

How to Make French Onion Sloppy Joes

Step 1 – In a large skillet, heat the olive oil over medium heat. Add the sliced onions and cook for 10–12 minutes, stirring occasionally, until soft and golden brown.

Step 2 – Add the minced garlic and cook for 1–2 minutes more, just until fragrant.

Step 3 – Stir in the ground beef. Cook for 5–7 minutes, breaking it up as it browns. Drain any excess fat.

Step 4 – Add Worcestershire sauce, soy sauce, thyme, salt, and pepper. Let the mixture simmer for about 5 minutes so all the flavors come together.

Step 5 – While the beef simmers, toast the buns lightly under the broiler until golden.

Step 6 – Spoon the beef mixture onto the bottom halves of the buns. Top with shredded Swiss cheese and return under the broiler for 1–2 minutes, just until the cheese is bubbling and melted.

Step 7 – Sprinkle with chopped parsley, add the top buns, and serve immediately.
