Ingredients: What You’ll Need
Here’s everything you need to make these irresistible French Onion Beef Sloppy Joes:
- 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)
Pro Tip: Use yellow or Vidalia onions for a sweeter, more mellow flavor when caramelized.
Step-by-Step Instructions: How to Make French Onion Sloppy Joes
Step 1: Caramelize the Onions
Start by heating 1 tablespoon of olive oil in a large skillet over medium heat. Add your thinly sliced onion and cook, stirring occasionally, for 10–12 minutes. The goal here is to draw out the natural sugars and let the onions turn a beautiful golden-brown color.
When the onions are soft and caramelized, stir in the minced garlic and cook for 1–2 more minutes until fragrant.
Caramelization Tip: Don’t rush this step! Low and slow is the secret to deep flavor.
Step 2: Brown the Ground Beef
Push the onions to the side of the skillet and add 1 pound of ground beef. Break it apart with your spatula and cook until fully browned—about 5–7 minutes. Once cooked, drain any excess fat to keep your sandwich from getting soggy.
Step 3: Add Seasoning and Simmer
Stir the onions and beef together, then add:
- 1 teaspoon Worcestershire sauce
- 1 teaspoon soy sauce
- 1 teaspoon dried thyme
- Salt and pepper to taste
Let the mixture simmer for about 5 minutes, allowing the flavors to meld together and the sauce to slightly thicken.
Step 4: Toast the Buns
While your beef mixture simmers, preheat your oven’s broiler. Slice the hamburger buns in half and place them cut-side up on a baking sheet. Lightly toast them under the broiler until golden brown—this helps keep them from getting soggy once you add the filling.
Optional: Brush the buns with a bit of melted butter for extra flavor and crispness.
Step 5: Assemble and Broil with Cheese
Spoon a generous portion of the beef mixture onto the bottom half of each bun. Top with shredded Swiss cheese (about ¼ cup per sandwich), then place them under the broiler again for 1–2 minutes, just until the cheese is melted and bubbly.
Step 6: Garnish and Serve
Remove from the oven, sprinkle with fresh chopped parsley, and top with the other half of the bun. Serve immediately while warm and cheesy.
Serve with: A simple green salad, oven-baked fries, or a dill pickle spear for a balanced plate.
