Making Cheesy Low Carb Philly Cheesesteak Casserole is surprisingly simple. Just follow these easy steps:

1. Preheat your oven to 350°F (175°C). Prepare a 9×13 inch baking dish by greasing it lightly.
2. Brown the beef: In a large skillet over medium heat, cook the ground beef (or steak slices) until browned. Drain excess grease.
3. Add vegetables: Stir in the onions, bell peppers, and mushrooms. Cook until softened, about 5-7 minutes, stirring occasionally.
4. Season properly: Add Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix well and cook for an additional 2-3 minutes.
5. Prepare the cheesy mixture: In a bowl, combine the softened cream cheese, heavy cream, and eggs. Whisk until smooth and creamy.
6. Combine ingredients: Stir in half the shredded cheese into the beef and vegetable mixture. Pour this mixture into the prepared baking dish.
7. Pour cheese mixture: Drizzle the cream cheese mixture over the top of the casserole, spreading it evenly.
8. Top with remaining cheese: Sprinkle the rest of the shredded cheese on top of the casserole.
9. Bake: Place in the preheated oven and bake for 15-20 minutes, or until the cheese is golden and bubbly.
10. Garnish: Remove from the oven and let it cool slightly. Garnish with freshly chopped parsley before serving.
