How to Make French Onion Beef Sloppy Joes
Step 1: Cook the Ground Beef
Start by browning the ground beef in a large skillet over medium heat. Use a spoon to break it up as it cooks. This step is crucial because it adds depth of flavor while ensuring your filling has that classic sloppy joe texture. Once cooked through, drain any excess fat.
Step 2: Caramelize the Onions
In the same skillet, melt butter and olive oil over medium-low heat. Add your thinly sliced onions and cook them slowly for about 15 minutes. Stir occasionally until they turn golden brown and caramelized. This process brings out their natural sweetness, which is vital for creating that delicious French onion flavor!
Step 3: Add Flavor
Now it’s time to elevate those onions! Stir in Worcestershire sauce and French onion soup mix, ensuring each slice of onion gets coated with that savory seasoning. This step packs your filling with wonderful flavor that everyone will love.
Step 4: Make the Sauce
Pour in the beef broth and let everything simmer together for about 5 minutes. This allows all those beautiful flavors to meld into one delicious sauce. Keep an eye on it—it should be warm and fragrant!
Step 5: Combine Beef and Onions
Return your browned beef back into the skillet with the onions. Stir everything together until well combined. Season with salt and pepper to taste; this is where you can adjust flavors based on your preference!
Step 6: Assemble the Sloppy Joes
Spoon that hearty mixture onto the bottom half of each bun. Don’t be shy—load them up! Top generously with shredded mozzarella cheese (or Swiss cheese) for that gooey finish.
Step 7: Melt the Cheese
To achieve melty perfection, place your assembled sandwiches under a broiler for about 1-2 minutes until the cheese is bubbly and golden brown. Just keep an eye on them so they don’t burn!
Step 8: Serve
Finally, add the top bun on each sandwich and serve immediately. These delightful French Onion Beef Sloppy Joes are ready to impress! Enjoy every cheesy bite!
