French Onion Beef Sloppy Joes (Printable)

Rich beef and caramelized onions with melted cheese on brioche buns for a comforting meal.

# What You'll Need:

→ Meats

01 - 1 lb ground beef, 80/20 blend preferred

→ Vegetables & Aromatics

02 - 2 large yellow onions, thinly sliced
03 - 2 cloves garlic, minced

→ Dairy

04 - 4 slices provolone cheese (Swiss or Gruyère also suitable)

→ Breads

05 - 4 brioche buns or hamburger rolls

→ Liquids

06 - 1/2 cup low sodium beef broth
07 - 1 tablespoon Worcestershire sauce

→ Pantry & Spices

08 - 2 tablespoons unsalted butter
09 - 1 tablespoon olive oil
10 - 1 tablespoon all-purpose flour
11 - 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried
12 - 1/2 teaspoon kosher salt, plus additional to taste
13 - 1/4 teaspoon black pepper, plus additional to taste

# Directions:

01 - Heat olive oil and butter in a large skillet over medium heat. Add onions and a pinch of salt. Cook, stirring occasionally, until caramelized and golden brown, approximately 12-15 minutes.
02 - Stir in minced garlic and thyme. Cook for 1 minute until fragrant.
03 - Push onions to the side of the pan. Add ground beef and break up with a spatula. Cook until browned and cooked through, about 5-6 minutes. Drain excess fat if necessary.
04 - Sprinkle flour over the beef and onions, stirring to coat evenly. Cook for 1 minute to remove raw flour taste.
05 - Pour in beef broth and Worcestershire sauce. Simmer for 3-4 minutes until the mixture thickens slightly. Season with salt and pepper to taste.
06 - Toast brioche buns under the broiler or in a skillet until golden and crisp.
07 - Spoon the beef and onion mixture onto the bottom half of each bun. Top with a slice of cheese. Place under the broiler for 1-2 minutes until cheese is melted and bubbly.
08 - Add the top bun and serve immediately while hot.

# Expert Advice:

01 -
  • The caramelized onions create this incredible depth that regular sloppy joes just dont have, making each bite feel like something youd order at a restaurant
  • Everything happens in one skillet, which means maximum flavor with minimum cleanup, exactly how weeknight cooking should work
02 -
  • Caramelizing onions properly takes patience, and rushing them over high heat makes them bitter instead of sweet, so keep the heat medium and let them do their thing
  • Draining the excess fat after browning the beef prevents the sandwiches from becoming too greasy, but leave about a tablespoon because that fat carries flavor
03 -
  • Adding a splash of dry sherry or white wine to the onions during the last five minutes of caramelizing gives them an incredible depth
  • Thinly slicing the onions against the grain helps them break down and caramelize more evenly than thick chunks
