Best Philly Cheese Steak Casserole

Instructions:

1. Preheat the Oven:

Preheat your oven to 350°F (175°C).
2. Cook the Beef (or Steak):
In a large skillet, heat the olive oil over medium heat. Add the ground beef (or sliced steak) and cook until browned. Drain any excess fat.

3. Sauté the Vegetables:

In the same skillet, add the diced onion, bell peppers, and mushrooms. Cook for about 5-7 minutes, stirring occasionally, until the vegetables are soft. Add the minced garlic and cook for another minute.

4. Season the Mixture:

Stir the Worcestershire sauce, salt, pepper, and Italian seasoning into the vegetable mixture. Combine this with the cooked beef or steak.

5. Make the Creamy Mixture:

In a medium bowl, mix the softened cream cheese and sour cream until smooth. Add the shredded provolone or mozzarella and stir until combined.

6. Assemble the Casserole:

In a greased 9×13-inch casserole dish, spread the beef and vegetable mixture evenly across the bottom. Top with the cream cheese mixture, spreading it evenly over the top.

7. Bake:

Sprinkle the shredded cheddar cheese on top of the casserole. Bake in the preheated oven for 20-25 minutes, until the cheese is melted and bubbly.

8. Serve:

Let the casserole cool slightly before serving. You can serve it as is, or spoon it into hoagie rolls for a more traditional Philly cheesesteak experience.
