These French onion sloppy joes taste like the classic French onion soup but in a sandwich! Sweet caramelized onions and seasoned ground beef topped with melted Swiss cheese make these way better than regular sloppy joes. They’re perfect for quick weeknight dinners when you want something special but easy.
What You Need (Ingredients)
- 1 pound ground beef
- 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 (for garnish)
How to Make French Onion Sloppy Joes (Step by Step)
Step 1: Cook the Onions Until Golden
Heat the olive oil in a large pan over medium heat. Add your sliced onions and cook them slowly for 10-12 minutes. Stir them every few minutes. They’re ready when they turn golden brown and smell sweet. This is called “caramelizing” – it makes the onions super flavorful!
Step 2: Add the Garlic
Add the chopped garlic to your golden onions and cook for 1-2 more minutes until you can smell it. Don’t let it burn!
Step 3: Cook the Ground Beef
Add the ground beef to the same pan with the onions and garlic. Use a spatula to break it up into small pieces. Cook for 5-7 minutes until all the pink is gone and the meat is browned. If there’s a lot of grease in the pan, carefully drain it off.
Step 4: Add the Seasonings
Stir in the Worcestershire sauce, soy sauce, dried thyme, salt, and pepper. Let everything simmer together for 5 minutes. This helps all the flavors mix together and taste amazing.
Step 5: Toast the Buns
While your beef mixture is simmering, turn on your oven’s broiler. Put the hamburger buns on a baking sheet and toast them under the broiler for 1-2 minutes until they’re lightly golden. Watch them carefully so they don’t burn!
Step 6: Build Your Sloppy Joes
Spoon the beef and onion mixture onto the bottom half of each toasted bun. Make sure you get plenty of those sweet onions! Sprinkle the Swiss cheese on top of each sandwich.
Step 7: Melt the Cheese
Put the open sandwiches back under the broiler for 1-2 minutes until the cheese is melted and bubbly. Keep an eye on them so the cheese doesn’t burn.
Step 8: Finish and Serve
Take the sandwiches out of the oven and sprinkle chopped parsley on top. Put the top bun on each sandwich and serve right away while they’re hot and the cheese is still melty!
Pro Tips for Perfect Sloppy Joes
- Take time with the onions: Don’t rush the caramelizing step. Sweet, golden onions make these sandwiches special.
- Drain the grease: Too much grease makes soggy sandwiches. Drain it off after cooking the beef.
- Toast those buns: Toasted buns hold up better and don’t get soggy from the beef mixture.
- Watch the broiler: Broilers work fast! Stay close so nothing burns.
Easy Ways to Change It Up
- Different cheese: Try provolone or mozzarella instead of Swiss
- Add mushrooms: Cook sliced mushrooms with the onions for extra flavor
- Make it spicy: Add a pinch of red pepper flakes with the seasonings
- Use turkey: Ground turkey works great instead of beef
- Add herbs: Fresh thyme tastes even better than dried if you have it
What to Serve With French Onion Sloppy Joes
These fancy sloppy joes go great with:
- Crispy french fries or sweet potato fries
- Simple green salad
- Pickle spears
- Onion rings (for extra onion flavor!)

Storage and Leftovers
Store leftover beef mixture in your fridge for up to 3 days. To reheat, warm it in a pan over medium heat until hot. You can also microwave it, but add the mixture to fresh buns and melt new cheese for the best taste.
Make It Ahead
You can make the beef and onion mixture ahead of time and store it in the fridge. When you’re ready to eat, just reheat the mixture, toast fresh buns, and add cheese.
