Ingredients:
For the beef mixture:
1 lb (450g) ground beef
1 tbsp olive oil or butter
1 large yellow onion, thinly sliced
1 garlic clove, minced
1/2 cup beef broth
1 tbsp Worcestershire sauce
1 tbsp tomato paste
1/2 tsp thyme (fresh or dried)
Salt & black pepper to taste
1 tsp cornstarch (optional, for thickening)
For assembly:
4 hamburger buns
4 slices provolone, mozzarella, or Swiss cheese
1 tbsp butter (for toasting buns, optional)
Instructions:
Caramelize the Onions
Heat olive oil or butter in a skillet over medium heat.
Add sliced onions and cook, stirring occasionally, for about 15 minutes, until golden and soft.
Add minced garlic and cook for 1 more minute.
Cook the Ground Beef
Add ground beef to the skillet with onions. Cook until browned and cooked through (about 6–8 minutes).
Drain excess fat.
Stir in tomato paste, Worcestershire sauce, thyme, and beef broth. Simmer for 5–7 minutes.
If the mixture is too liquidy, dissolve 1 tsp cornstarch in 1 tbsp water and stir in to thicken. Season with salt and pepper to taste.
Preheat Air Fryer
Preheat your air fryer to 360°F (182°C) for 3–5 minutes.
Assemble the Sloppy Joes
Spoon the French onion beef mixture onto the bottom halves of buns.
Top each with a slice of cheese.
Place the top buns over the cheese and press gently.
Air Fry to Toast & Melt
Place assembled sandwiches in the air fryer basket (line with foil or parchment for easier cleanup).
Air fry at 360°F (182°C) for 4–6 minutes, until the cheese is melty and buns are slightly crisp.
If desired, butter the tops of the buns before air frying for extra golden color.
Tips & Variations:
Add a splash of balsamic vinegar for a deeper onion flavor.
Use Hawaiian rolls or slider buns for party-sized mini sloppy joes.
Mix in a bit of Gruyère cheese for authentic French onion flavor.
Want a spicy twist? Add a pinch of crushed red pepper or a dash of hot sauce.
