How to Make French Onion Beef Sloppy Joes

  1. Caramelize onions: In a large skillet, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add the thinly sliced onions, stirring occasionally, and cook until they turn golden brown, about 15-20 minutes.

  2. Brown the beef: Push the onions to the side of the skillet and add 1 lb of ground beef. Brown it thoroughly, breaking up the meat as it cooks. Drain any excess fat before continuing.

  3. Add flavors: Stir in 2 cloves of minced garlic, 1 teaspoon of thyme, 1 tablespoon of Worcestershire sauce, and 1 cup of beef broth. Mix well, and bring the mixture to a simmer.

  4. Thicken the mixture: Allow the filling to simmer for about 5-10 minutes, or until it slightly thickens. You want a hearty consistency without too much liquid.

  5. Stir in onions: Gently fold the caramelized onions into the beef mixture, ensuring they’re well distributed for maximum flavor.

  6. Melt the cheese: Top the mixture with 6 slices of provolone or Gruyere cheese. Cover the skillet with a lid and let it cook for a few minutes, allowing the cheese to melt beautifully.

  7. Assemble and serve: Spoon the cheesy beef mixture onto toasted sandwich buns, making sure to capture plenty of gooey goodness. Serve hot and enjoy your delicious creation!

French Onion Beef Sloppy Joes Recipe FAQs

What kind of onions are best for caramelizing?
Absolutely! For the richest flavor, I recommend using yellow or sweet onions. These varieties caramelize beautifully, providing that sweet, savory taste that elevates your French Onion Beef Sloppy Joes. Avoid red onions for this recipe, as they can become too sharp when cooked.

How should I store leftovers?
You can store any leftover French Onion Beef Sloppy Joes in an airtight container in the fridge for up to 3 days. When reheating, simply microwave the filling or warm it in a skillet on low heat until heated through, ensuring that it stays juicy and flavorful.

Can I freeze the filling?
Very! To freeze the beef mixture, transfer it to an airtight freezer bag after it has cooled completely. Press out any excess air and seal tightly. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy it, thaw the bag in the refrigerator overnight, then reheat it on the stove, adding a splash of beef broth if needed.

What should I do if the filling is too runny?
If your filling turns out too liquidy, don’t worry! Simply simmer it on low heat for an additional 5-10 minutes without the lid, allowing some liquid to evaporate and the mixture to thicken. Stir occasionally to avoid sticking to the bottom of the pan. If you find that it’s still not thickening, you can also mix a teaspoon of cornstarch with a tablespoon of cold water, then stir it into the mixture until it reaches your desired consistency.

Are there any dietary considerations for this recipe?
Absolutely! If you’re catering to dietary restrictions, consider using ground turkey or chicken for a leaner option or gluten-free buns for those who are gluten-sensitive. Always check your Worcestershire sauce for allergens, as some brands may contain gluten or anchovy paste. For those avoiding dairy, you can simply omit cheese or use a dairy-free alternative that melts well.

Can I make this recipe vegetarian?
Yes, you can! For a vegetarian version, substitute the ground beef with lentils or a plant-based meat substitute. Use vegetable broth instead of beef broth and opt for a vegan cheese that melts nicely. The caramelized onions and seasonings will still provide that comforting flavor without the meat. Enjoy your French Onion Beef Sloppy Joes, even in a veggie twist!
