Step 1: Brown the Ground Beef
Heat a large cast iron skillet over medium-high heat. Add the ground beef and allow it to brown without stirring initially to form a deep crust.
Break the beef apart and continue to cook until about 50% of it has developed a deep crust.
Step 2: Sauté the Vegetables
Remove the beef from the skillet, leaving behind any fat. Add butter to the skillet.
Sauté the diced onion, bell pepper, and minced mushrooms until browned and tender.
Step 3: Combine Ingredients
Return the beef to the skillet with the sautéed vegetables.
In a small bowl, dissolve the cornstarch in the beef broth and then pour into the skillet. Add ketchup, Worcestershire sauce, salt, and pepper.
Stir everything together and let simmer until the mixture thickens, ensuring most of the beef is above the liquid level.
Step 4: Add the Cheese
Turn off the heat. Stir in the chopped Provolone cheese until it’s melted and the mixture is creamy.
Step 5: Toast the Buns
Toast the brioche buns under a broiler or in a separate skillet until they are golden brown.
Step 6: Assemble and Serve
Spoon the beef and cheese mixture onto the toasted buns.
Serve hot, ensuring each sandwich is loaded with the savory filling.
