How to Make Philly Cheesesteak Casserole
Step 1: Prepare the Pasta
Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish.
Cook the pasta according to package instructions, drain, and add it to the prepared baking dish.
Step 2: Cook the Beef and Vegetables
Heat 1 tablespoon of olive oil in a large skillet over medium heat.
Add ground beef and cook for about 4 minutes.
Add sliced peppers and onions, cooking until the beef is fully browned and vegetables are tender, about 8 minutes.
Step 3: Season and Thicken
Stir in garlic, oregano, salt, and crushed red pepper. Cook for 1 minute until fragrant.
Sprinkle flour over the mixture and cook, stirring, for 1 minute.
Gradually add the beef broth, stirring until the mixture thickens and becomes bubbly.
Step 4: Add the Cheese
Add cream cheese and stir until fully melted and smooth.
Mix in 1 cup of shredded provolone cheese until melted and creamy.
Step 5: Assemble the Casserole
Pour the beef mixture over the pasta and stir gently to combine.
Top with the remaining ½ cup provolone cheese.
Step 6: Add the Crumb Topping
In a small bowl, toss bread crumbs with the remaining 2 tablespoons olive oil.
Sprinkle evenly over the casserole.
Step 7: Bake
Bake uncovered for 20 minutes, or until the top is golden brown and the casserole is bubbly.

Helpful Tips
