Ingredients
Scale
- 1 pound lean ground beef
- 2 tablespoons butter
- 1 small yellow onion, diced
- 1 small green bell pepper, diced
- 8 ounces brown mushrooms, minced
- 2 tablespoons ketchup
- 1 tablespoon Worcestershire sauce
- 1/2 teaspoon kosher salt
- 1/2 teaspoon fresh ground black pepper
- 1 tablespoon cornstarch
- 1 cup beef broth
- 8 ounces provolone cheese slices, chopped
- 6 brioche hamburger buns
Instructions
- Heat a large cast iron skillet over medium-high heat. Add the ground beef and cook until it develops a deep brown crust before breaking it apart. Continue cooking until about half of the beef has browned.
- Remove the beef from the skillet, leaving the rendered fat. Add butter, diced onion, bell pepper, and minced mushrooms to the skillet.
- Allow the vegetables to brown for 1–2 minutes without stirring, then stir and cook another 1–2 minutes until lightly caramelized.
- Return the cooked beef to the skillet with the vegetables.
- In a small cup, whisk together the beef broth and cornstarch until smooth. Pour into the skillet along with ketchup, Worcestershire sauce, salt, and pepper.
- Cook the mixture for 3–5 minutes until the sauce thickens and coats the beef and vegetables.
- Turn off the heat and stir in the chopped provolone cheese until melted and creamy.
- Serve the mixture piled onto toasted brioche buns.
Notes
- For a lighter version, substitute ground turkey or chicken for the beef.
- Add jalapeños or red pepper flakes for extra heat.
- Serve with fries, potato chips, or a fresh salad for a complete meal.
