FAQs
Can I use ground turkey instead of beef?
Yes, ground turkey works well as a leaner alternative. Cook it the same way, but keep an eye on moisture since turkey can dry out faster.
How do I keep the buns from getting soggy?
To prevent sogginess, toast the buns well and add the beef mixture just before serving. You can also spread a thin layer of butter or mayonnaise on the buns to create a moisture barrier.

Ingredients
Main Ingredients
- 1 pound ground beef (85% lean)
- 1 large onion, thinly 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 hamburger buns
- 1 cup shredded Swiss cheese
- Fresh parsley, chopped (optional for garnish)
Instructions
- Heat the Oil and Caramelize Onions: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the thinly sliced onion and cook for 10-12 minutes, stirring often, until they become golden and caramelized, developing a rich and sweet flavor base.
- Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes to release its aroma without burning.
- Cook the Ground Beef: Add 1 pound of ground beef to the skillet. Cook it thoroughly until fully browned, breaking it apart with a spatula to ensure even cooking and no large clumps remain.
- Season the Meat Mixture: Drain any excess fat from the skillet. Then, stir in 1 teaspoon each of Worcestershire sauce and soy sauce, 1 teaspoon dried thyme, along with salt and pepper to taste. These ingredients add depth and a savory umami kick to the sloppy joe mixture.
- Simmer the Mixture: Let the combined mixture simmer for another 5 minutes. This allows the flavors to meld beautifully, making the filling juicy and flavorful.
- Toast the Buns: While the meat simmers, toast the 4 hamburger buns until golden and slightly crisp to provide a sturdy base and contrast in texture to the juicy beef.
- Assemble the Sloppy Joes: Spoon the French onion beef mixture onto the bottom half of each toasted bun. Top generously with 1 cup of shredded Swiss cheese so that it slightly melts from the residual heat. Optionally, sprinkle chopped fresh parsley on top for color and freshness.
- Serve: Place the top bun over the cheese and serve immediately while warm and delicious.
Notes
- For extra richness, use a mix of Swiss and Gruyère cheese.
- Caramelizing onions slowly is key to developing the deep flavor—don’t rush this step.
- You can add a splash of red wine during the simmer for a more complex sauce.
- Serve with pickles or a side salad for a balanced meal.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
