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 essential because it helps develop flavor and ensures even cooking. Don’t forget to drain any excess fat afterward!
Step 2: Caramelize the Onions
In the same skillet, melt butter and 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 enhances their natural sweetness and adds depth to your dish.
Step 3: Add Flavor
Next, stir in Worcestershire sauce and the packet of French onion soup mix. Mix everything well so that the onions are coated with seasoning. This step brings all those flavors together beautifully!
Step 4: Make the Sauce
Pour in the beef broth and let everything simmer for about 5 minutes. This allows all the flavors to meld together into a comforting sauce that will soak into your buns later.
Step 5: Combine Beef and Onions
Return the browned beef to the skillet with the onions. Stir well to combine everything thoroughly, then season with salt and pepper according to your taste. It should smell absolutely heavenly at this point!
Step 6: Assemble the Sloppy Joes
Spoon generous amounts of the mixture onto the bottom half of each bun. Be sure to load them up nice and high — no one likes a skimpy sloppy joe! Top each one with shredded cheese.
Step 7: Melt the Cheese
To get gooey cheese perfection, place your assembled sandwiches under a broiler for about 1-2 minutes. Keep an eye on them; you want them melted but not burnt!
Step 8: Serve
Finally, add on top buns and serve immediately while they’re warm and cheesy! These sandwiches are sure to become a favorite at your table!
