Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Ground beef
Yellow onions, thinly sliced
Garlic, minced
Beef broth
Worcestershire sauce
Tomato paste
Brown sugar
Salt and pepper
Olive oil
Provolone or mozzarella cheese slices
Hamburger buns

Directions

I start by heating a little olive oil in a large skillet over medium heat. I add the sliced onions and cook them slowly until they’re golden brown and caramelized—this step builds that deep, French onion flavor.
I stir in the minced garlic and let it cook for about a minute until fragrant.
Then I add the ground beef, breaking it apart with a spoon, and cook it until it’s browned and fully cooked through.
I stir in the tomato paste, Worcestershire sauce, brown sugar, salt, and pepper. Then I pour in the beef broth and let the mixture simmer until the liquid reduces and thickens into a saucy consistency.
Once it’s nice and thick, I toast the hamburger buns and spoon the beef mixture onto the bottoms.
I lay a slice of provolone or mozzarella cheese over the meat and place the top bun on.
Sometimes, I pop the assembled sloppy joes under the broiler for a minute to get the cheese nice and melty.

Servings and timing

This recipe makes 4 to 6 servings and takes about 35 minutes total—20 minutes for prep and 15 minutes for cooking. It’s perfect for a quick weeknight dinner or a weekend comfort meal.

Variations

If I want to switch things up, I use ground turkey or chicken instead of beef for a lighter version. For an extra flavor boost, I sometimes add a splash of red wine while the onions are caramelizing. If I’m in the mood for spice, I toss in a pinch of crushed red pepper or a few dashes of hot sauce. And for a richer finish, I like topping the sandwiches with a bit of gruyère cheese instead of provolone.

Storage/Reheating

Leftovers keep well in an airtight container in the fridge for up to 4 days. When I reheat them, I do it on the stovetop over medium heat until warmed through, or in the microwave in 30-second bursts. I store the beef mixture and buns separately to avoid sogginess.

FAQs

How do I make this recipe vegetarian?

I swap the ground beef with lentils or a plant-based ground meat alternative and use vegetable broth instead of beef broth.

Can I make this ahead of time?

Yes, I often make the beef mixture in advance and store it in the fridge. Then I just reheat and assemble the sandwiches when ready to serve.

What’s the best cheese to use?

I love using provolone or mozzarella, but gruyère gives it an authentic French onion soup flavor if I want something more gourmet.

Can I freeze the meat mixture?

Absolutely. I let it cool completely, then freeze it in a sealed container. It keeps well for up to 2 months. Thaw in the fridge overnight and reheat before serving.

What kind of buns work best?

I usually go with soft brioche buns, but any hamburger buns or even hoagie rolls work great. I always toast them lightly to hold up to the juicy filling.
