These French Onion Beef Sloppy Joes are a rich, savory twist on a classic sandwich loaded with caramelized onions, juicy seasoned beef, melty cheese, and soft brioche buns.

Ingredients

Scale
  • 1 lb ground beef
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons butter
  • 2 cloves garlic, minced
  • 1/2 cup beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon balsamic vinegar
  • 1/2 teaspoon dried thyme (or 1 teaspoon fresh thyme)
  • Salt, to taste
  • Black pepper, to taste
  • 4 slices Gruyère or provolone cheese
  • 4 brioche buns
  • Fresh parsley, chopped (optional for garnish)

Instructions

  1. Melt butter in a skillet over medium heat. Add sliced onions and a pinch of salt. Cook for 25–30 minutes, stirring occasionally, until deeply caramelized.
  2. Push onions to one side of the skillet and add ground beef. Cook until browned, about 6–8 minutes. Combine with onions.
  3. Stir in garlic, Worcestershire sauce, balsamic vinegar, and thyme. Cook for 2 more minutes.
  4. Pour in beef broth, bring to a simmer, and reduce heat. Let the mixture cook for 5–10 minutes until thickened. Season with salt and pepper.
  5. Lightly butter brioche buns and toast them in a skillet or under the broiler until golden.
  6. Spoon beef mixture onto bottom buns, top with cheese, and broil for 1–2 minutes until the cheese is melted and bubbly.
  7. Add top buns, garnish with parsley if desired, and serve hot.
