Cook pasta shells according to package instructions; drain and set aside.
In a large skillet, cook ground beef (or steak) over medium heat until browned. Drain excess grease.
Add onion, bell pepper, mushrooms, and garlic to the skillet. Cook until softened.
Stir in Worcestershire sauce, Italian seasoning, salt, and pepper.
Pour in beef broth and heavy cream. Simmer for 3-5 minutes.
Add cooked pasta shells and mix well.
Transfer mixture to a greased baking dish. Sprinkle with cheese.
Bake at 375°F for 15-20 minutes until cheese is melted and bubbly.
Let sit for a few minutes before serving.
Note: For an extra cheesy and flavorful casserole, try mixing provolone and mozzarella cheese. You can also substitute ground beef with thinly sliced ribeye or roast beef for a more authentic Philly cheesesteak taste. Serve with garlic bread or a side salad for a complete meal! 🧀🥩🍽️
Enjoy this creamy, cheesy twist on a Philly cheesesteak! 🧀🥩
