How to Make High Protein Philly Cheesesteak Casserole
This High Protein Philly Cheesesteak Casserole is a triumph of flavor and convenience, delivering all the beloved elements of a classic cheesesteak in an effortless, baked format. It’s incredibly simple to assemble, boasts a rich, creamy texture from the cheese sauce, and offers a deeply satisfying, savory taste that will have you coming back for more.

Step-by-Step Instructions:
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Brown the Meat: In a large skillet over medium-high heat, add the olive oil. Add the ground beef or turkey and cook, breaking it up with a spoon, until browned and no pink remains. Drain off any excess grease.
- Sauté Vegetables: Add the sliced green bell peppers, yellow onion, and mushrooms to the same skillet with the browned meat. Cook, stirring occasionally, until the vegetables are softened, about 8-10 minutes.
- Season the Mixture: Stir in the garlic powder, Italian seasoning, salt, and pepper. Cook for another minute until fragrant.
- Create the Creamy Sauce: In a medium bowl, whisk together the softened cream cheese, almond milk, beef broth, and Worcestershire sauce until smooth and well combined.
- Combine and Layer: Pour the creamy sauce over the meat and vegetable mixture in the skillet. Stir until everything is evenly coated.
- Assemble the Casserole: Transfer the meat and vegetable mixture from the skillet into the prepared baking dish, spreading it evenly.
- Add the Cheese: Sprinkle 1 cup of the shredded provolone cheese and the shredded mozzarella cheese evenly over the top of the casserole.
- Final Topping: Reserve the remaining 1/2 cup of provolone cheese and sprinkle it over the top of the casserole. This will melt and become wonderfully golden.
- Bake to Perfection: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the casserole is bubbling and the cheese is melted and golden brown.
- Rest and Serve: Let the casserole rest for 5-10 minutes before serving. Garnish with fresh chopped parsley, if desired.

- Reheating: For best results, reheat individual portions in the microwave at 30-second intervals, stirring in between, until heated through. Alternatively, reheat the entire casserole in a preheated oven at 350°F (175°C) until warmed through, about 15-20 minutes. You may want to cover it with foil to prevent the cheese from over-browning.
- Freezing: This casserole freezes well, although the texture of the vegetables might soften slightly upon thawing. To freeze, let the casserole cool completely. Portion it into freezer-safe containers or wrap individual servings tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator and reheat as directed above.
