🍳 Instructions

1. Heat the Oven: Preheat to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Brown the Meat: Cook the beef in a large skillet over medium-high heat until fully browned. Drain off excess fat.
3. Cook the Vegetables: Add onion, peppers, mushrooms, and garlic to the skillet. Sauté for 5–6 minutes until softened. Season with salt, pepper, smoked paprika, and Worcestershire sauce.
4. Transfer to Dish: Spread the beef and vegetable mixture evenly in the prepared baking dish.
5. Prepare the Creamy Mixture: In a bowl, whisk together the cream cheese, mayonnaise, and eggs until smooth.
6. Assemble the Casserole: Pour the creamy mixture over the beef and vegetables. Sprinkle provolone and mozzarella evenly over the top.
7. Bake: Place in the oven and bake for 25–30 minutes, until the cheese is melted, golden, and bubbling.
8. Rest & Serve: Let the casserole sit for 5 minutes before serving. Enjoy it on its own or alongside a fresh salad, crusty bread, or toasted hoagie rolls.
