How to Make Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside.
Step 2: Cook the Beef
Heat the olive oil in a large skillet over medium-high heat. Add the ground beef or shaved steak and cook until browned. Drain any excess grease if necessary.
Step 3: Sauté the Vegetables
Add the sliced onions, bell peppers, mushrooms, and garlic to the skillet. Cook for 6–8 minutes until the vegetables become tender and lightly caramelized.
Step 4: Add the Creamy Mixture
Stir in the Worcestershire sauce, Italian seasoning, salt, black pepper, softened cream cheese, and beef broth. Continue stirring until the cream cheese melts into a smooth, creamy sauce that coats the beef and vegetables.
Step 5: Assemble the Casserole
Transfer the beef mixture to the prepared baking dish and spread it evenly.
Step 6: Add the Cheese
Arrange the provolone cheese slices across the top, then sprinkle the shredded mozzarella evenly over everything.
Step 7: Bake and Serve
Bake for 18–20 minutes, or until the cheese is melted, bubbly, and lightly golden. Garnish with chopped parsley and serve hot.
