Method
- Butter the cut sides of the brioche buns and toast them face-down in a large skillet over medium heat until golden brown. Set aside.
- In the same skillet over medium-high heat, add the ground beef. Cook until deeply browned and no pink remains. Drain excess grease, leaving about 1 tablespoon in the pan.
- Add the diced onion, green bell pepper, and mushrooms to the beef. Sauté for 5-7 minutes until the vegetables are softened.
- Stir in the minced garlic, salt, black pepper, Worcestershire sauce, and ketchup. Cook for 1 minute until fragrant.
- Pour in the beef broth and scrape up any browned bits from the bottom of the pan. Bring to a gentle simmer for 3 minutes.
- Whisk the cornstarch and cold water together to create a slurry. Stir the slurry into the skillet. Simmer for 1-2 minutes until the sauce becomes thick and glossy. Remove from heat.
- Place slices of provolone cheese directly over the hot meat mixture. Cover with a lid for 2 minutes until melted.
- Scoop the cheesy beef mixture onto the toasted brioche buns and serve immediately.
Notes
Leftover meat mixture can be stored in an airtight container in the fridge for up to 4 days or frozen for up to 3 months. Perfect served over french fries as loaded fries!
