→ Vegetables & Aromatics

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

→ Dairy

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

13 - 1/4 teaspoon black pepper, plus more to taste

# How to Make It:

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, about 12–15 minutes.
02 - Add minced garlic and thyme; cook for 1 minute until fragrant.
03 - Push onions to the side of the pan. Add the ground beef to the skillet and break it up with a spatula. Cook until browned and cooked through, about 5–6 minutes. Drain excess fat if needed.
04 - Sprinkle flour over the beef and onions, stirring well to coat. Cook for 1 minute.
05 - Stir 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.
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 the cheese is melted and bubbly.
08 - Add the top bun and serve hot.

# Expert Advice:

  • The slow-cooked onions add a sweetness that balances perfectly with the savory beef
  • It takes the nostalgic Sloppy Joe you grew up on and makes it feel fancy enough for company
  • Everything cooks in one skillet, making cleanup almost as easy as the eating
02 -
  • Caramelizing onions properly takes patience, so don't try to rush it by cranking the heat or they will burn instead of sweeten
  • Letting the flour cook for a full minute prevents your sauce from tasting like raw paste
  • The mixture thickens quickly as it cools, so season when it is hot and remember it will be even thicker by serving time
03 -
  • Use a box grater to shred your cheese instead of slicing it for faster, more even melting
  • Grated fresh nutmeg in the onion mixture adds a subtle warmth that makes people ask what your secret ingredient is
