- 1 medium yellow onion, thinly sliced
- 1 tablespoon Worcestershire sauce
- 1 tablespoon soy sauce (optional for extra flavor)

- ½ cup beef broth or water
- 1 tablespoon cornstarch (to thicken)

Step by Step Process – French Onion Beef Sloppy Joes
Making this dish is super simple. Follow these steps:
Step 1: Cook the Onions
- In a large skillet, heat the olive oil over medium heat.
- Add the sliced onions and cook them slowly. Stir often for about 10–12 minutes until they become golden brown and soft. This step gives the dish that special “French onion” flavor.
Step 2: Brown the Ground Beef
- Add the ground beef to the pan with the onions.
- Break it up using a wooden spoon and cook until it’s fully browned and no pink remains. This will take about 6–8 minutes.
Step 3: Season the Mixture
- Add garlic powder, salt, pepper, Worcestershire sauce, soy sauce (if using), and the crushed bouillon cube.
- Stir everything well so the flavors mix evenly.
Step 4: Make It Saucy
- In a small bowl, mix the beef broth and cornstarch. Stir until smooth.
- Pour this mix into the skillet with the beef.
- Add brown sugar if you’d like a touch of sweetness.
- Let the mixture simmer on low heat for 5 minutes, stirring often, until the sauce thickens.
Step 5: Toast the Buns (Optional)
- In a separate pan or toaster, lightly butter the buns and toast them for a minute or two. This keeps them from getting soggy when you add the filling.
Step 6: Assemble the Sloppy Joes
- Spoon the hot beef and onion mixture onto the bottom half of each bun.
- Sprinkle shredded cheese over the top while it’s still warm, so it melts.
- Add the top bun and press lightly.
And that’s it! You’re ready to serve your delicious French Onion Beef Sloppy Joes.
