| Onion (diced) | 1 medium |
| Green bell pepper (diced) | 1 |
| Red bell pepper (diced) | 1 |
| Mushrooms (sliced) | 8 oz |
| Garlic (minced) | 2 cloves |
| Salt | 1 tsp |
| Black pepper | ½ tsp |
| Smoked paprika (optional) | ½ tsp |
| Worcestershire sauce | 1 tbsp |

Instructions
Step 1: Preheat and Prepare: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Step 2: Cook the Beef: In a large skillet over medium-high heat, cook the ground beef until it’s browned and fully cooked. Drain off any excess grease to keep your casserole rich but not oily.
Step 3: Sauté the Vegetables: Add the diced onion, green and red bell peppers, mushrooms, and minced garlic to the skillet. Cook for about 5–6 minutes, stirring often, until the vegetables are tender and aromatic. Season with salt, pepper, smoked paprika (if using), and Worcestershire sauce for that signature Philly flavor.
Step 4: Layer the Mixture: Transfer the cooked beef and veggie blend into your prepared baking dish, spreading it evenly to create the base layer.
Step 5: Make the Creamy Base: In a medium bowl, whisk together the softened cream cheese, mayonnaise, and eggs until smooth and creamy. This will give the casserole its rich, custard-like texture.
Step 6: Assemble the Casserole: Pour the creamy mixture over the beef and vegetables, ensuring it covers everything evenly. Then sprinkle the shredded provolone and mozzarella cheese generously on top.
Step 7: Bake: Place the dish in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and bubbling.
Step 8: Rest and Serve: Let the casserole sit for about 5 minutes before serving so it sets nicely. Enjoy it as is, or pair it with a side salad, crusty bread, or even toasted hoagie rolls for the ultimate Philly-inspired meal.
