Creating your Low Carb Philly Cheesesteak Casserole is a straightforward process that anyone can follow. Here’s how to make it step-by-step:

1. Preheat Oven: Set your oven to 350°F (175°C) to preheat while you prepare the other ingredients.

2. Cook the Beef: In a large skillet, heat olive oil over medium heat. Add the sliced beef and cook until browned, about 3-4 minutes.

3. Add Vegetables: Stir in the sliced onions, bell peppers, and mushrooms (if using). Cook for an additional 4-5 minutes, until vegetables are softened.

4. Season: Add the minced garlic, salt, pepper, and Italian seasoning to the skillet. Mix everything well and allow to sauté for another 1-2 minutes.

5. Incorporate Cream Cheese: Remove the skillet from heat. Stir in the softened cream cheese until fully incorporated, creating a creamy mixture.

6. Transfer to Baking Dish: Pour the beef and vegetable mixture into a greased 9×13-inch baking dish. Spread it out evenly.

7. Add Cheese: Sprinkle the shredded provolone and mozzarella cheese over the top of the beef and vegetables.

8. Bake: Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.

9. Garnish: Once done, remove the dish from the oven and let it cool for a few minutes. Garnish with fresh, chopped parsley for added flavor.

10. Serve: Cut into portions and serve warm.
