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. As it cooks, break it up with a spoon until it’s evenly browned. Drain any excess fat—this keeps your sloppy joes from becoming greasy.
Step 2: Caramelize the Onions
In the same skillet, melt butter and olive oil over medium-low heat. Add those sliced onions and let them cook for about 15 minutes. Stir occasionally until they turn golden brown and caramelized. This step is key because caramelizing brings out their natural sweetness, adding depth to your dish.
Step 3: Add Flavor
Once your onions are beautifully caramelized, stir in Worcestershire sauce and the French onion soup mix. This will coat the onions with flavor. It’s an easy way to infuse that delicious French onion taste right into your sloppy joes.
Step 4: Make the Sauce
Pour in the beef broth and let everything simmer for about 5 minutes. This allows all those wonderful flavors to meld together nicely. The mixture should thicken up slightly during this time.
Step 5: Combine Beef and Onions
Return the cooked ground beef to the skillet, mixing it well with the caramelized onions. Season with salt and pepper according to your taste preferences—this step finishes off your filling perfectly!
Step 6: Assemble the Sloppy Joes
Spoon generous amounts of the mixture onto the bottom half of each bun. Be sure not to skimp on that delicious filling! Top each one with heaps of shredded cheese.
Step 7: Melt the Cheese
Pop them under a broiler for just 1-2 minutes until that cheese is gloriously melted and bubbly. Keep an eye on them so they don’t burn—cheesy perfection is just moments away!
Step 8: Serve
Finally, add the top bun on each sandwich and serve immediately while they’re warm and cheesy. Your family will thank you for this delightful meal!
Now you’re ready to delight everyone at your table with these comforting French Onion Beef Sloppy Joes! Enjoy every bite!
