How to Make French Onion Beef Sloppy Joes
Step 1: Cook the Ground Beef
Start by browning 1 pound of ground beef in a large skillet over medium heat. As it cooks, use a spoon to break it up into smaller pieces. This step is crucial as it creates that beautiful texture we all love in sloppy joes. Once browned, drain any excess fat.
Step 2: Caramelize the Onions
In the same skillet, melt 2 tablespoons of butter along with 1 tablespoon of olive oil over medium-low heat. Add your thinly sliced onions and let them cook for about 15 minutes, stirring occasionally until they turn golden brown and caramelized. This process brings out their natural sweetness and adds depth to our dish.
Step 3: Add Flavor
Next, stir in 2 teaspoons of Worcestershire sauce and your packet of French onion soup mix into the caramelized onions. Mix well so that every onion slice is coated with those delicious seasonings. This step ensures every bite is packed with flavor!
Step 4: Make the Sauce
Now pour in 1 cup of beef broth and let everything simmer for about 5 minutes. This allows all those wonderful flavors to meld together beautifully.
Step 5: Combine Beef and Onions
Return your cooked ground beef back into the skillet and give everything a good stir to combine it with those tasty onions. Season with salt and pepper to taste—this final touch really elevates your sloppy joes!
Step 6: Assemble the Sloppy Joes
Spoon generous portions of the mixture onto the bottom half of each hamburger bun, then top each one with shredded mozzarella cheese (or Swiss cheese).
Step 7: Melt the Cheese
Place your assembled sandwiches under a broiler for just 1-2 minutes until the cheese is melted and bubbly. Keep an eye on them so they don’t burn—nobody likes burnt cheese!
Step 8: Serve
Finally, add the top bun and serve immediately while everything is warm and gooey. Enjoy each bite of these comforting French Onion Beef Sloppy Joes!
Pro Tips for Making French Onion Beef Sloppy Joes
Making the perfect French Onion Beef Sloppy Joes is all about attention to detail, and these pro tips will help you create a mouthwatering meal that your family will adore.
-
Choose the Right Cheese: Opting for mozzarella or Swiss cheese not only adds creaminess but also melts beautifully, making your sandwiches ooze with cheesy goodness.

Don’t Rush the Onions: Caramelizing the onions slowly allows their natural sugars to develop, enhancing their sweetness and flavor. Aim for that golden-brown hue for the best results.
