1. Preheat & Prepare:
Set the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Cook the Beef:
In a large skillet over medium-high heat, cook the beef until browned and no longer pink. Drain excess grease.
3. Sauté the Vegetables:
Add the onion, green and red peppers, mushrooms, and garlic to the same skillet. Cook for 5–6 minutes, until softened. Season with salt, pepper, smoked paprika, and Worcestershire sauce.
4. Layer the Filling:
Spread the cooked beef and vegetable mixture evenly in the prepared baking dish.
5. Make the Creamy Mixture:
In a bowl, whisk together the softened cream cheese, mayonnaise, and eggs until smooth and well combined.
6. Assemble the Casserole:
Pour the creamy mixture evenly over the beef and vegetables. Sprinkle shredded provolone and mozzarella on top.
7. Bake to Perfection:
Bake for 25–30 minutes, until the cheese is melted, golden, and bubbly.
8. Rest & Serve:
Allow the casserole to rest for about 5 minutes before serving. Enjoy it as is, or pair with a crisp salad, crusty bread, or toasted hoagie rolls for a true Philly experience.
