Ingredients

1 lb ground beef
2 large onions, thinly sliced
2 tablespoons olive oil
1 tablespoon butter
1 packet French onion soup mix
1 cup beef broth
4 hamburger buns
Salt and pepper to taste
Optional: shredded cheese for topping

Step by Step Instructions

Heat olive oil and butter in a skillet over medium heat. Add onions and cook until caramelized, about 15-20 minutes.
Add ground beef to the skillet, breaking it up, and cook until browned.
Stir in the French onion soup mix and beef broth, simmering for 5-10 minutes.
Season with salt and pepper.
Serve the mixture on toasted hamburger buns, topped with cheese if desired.

Tips for Best Results

Cook the onions slowly and patiently so they develop a deep, golden brown color without burning. Use medium heat and stir occasionally; adding a pinch of salt early helps draw out moisture and speed caramelization. If the mixture seems thin after adding broth, simmer a bit longer to reduce and concentrate flavors. For extra richness, finish with a small knob of butter or a splash of extra broth if it gets too dry. Toasting the buns in the same pan for a minute helps them soak up the savory juices without falling apart.

Storage and Make Ahead

This filling stores well in an airtight container in the refrigerator for up to three days. Reheat gently in a skillet or microwave, adding a splash of broth if the mixture has thickened too much. You can also make the caramelized onions ahead and refrigerate them separately to speed assembly on a busy night. For freezer storage, cool completely and freeze in a sealable container for up to two months; thaw overnight in the fridge before reheating.

Final Thought

These French onion beef sloppy joes are a comforting twist on a classic, turning simple pantry items into a cozy, flavorful meal. They’re versatile, quick to prepare, and ideal for feeding a hungry crowd or saving as tasty leftovers. Try pairing them with a crisp salad or roasted potatoes for a complete, satisfying dinner.
