🍳 Instructions
1. Preheat the Oven
Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. This keeps the casserole from sticking.
2. Cook the Beef
Heat a large skillet over medium-high heat. Add the ground beef or shaved steak and cook until browned.
Break it up as it cooks. Drain any excess fat to keep the casserole from becoming greasy.
3. Sauté the Vegetables
Add the diced onion, green pepper, red pepper, mushrooms, and garlic to the same skillet.
Cook for about 5–7 minutes until the vegetables soften and release their flavors.
Season with:
- Salt
- Black pepper
- Smoked paprika (optional)
- Worcestershire sauce
4. Make the Creamy Binder
In a mixing bowl, whisk together:
- 8 oz softened cream cheese
- ½ cup mayonnaise
- 2 large eggs
This creates a rich, silky mixture that holds the casserole together and gives it a creamy, irresistible texture.
5. Combine Everything
Add the cooked meat and vegetable mixture to the cream mixture. Stir until everything is fully combined.
6. Assemble the Casserole
Spread the mixture evenly into your prepared baking dish. Sprinkle the top generously with:
- 1 cup shredded provolone
- 1 cup shredded mozzarella
7. Bake
Bake for 25–30 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
8. Rest & Serve
Let the casserole rest for 5 minutes before slicing. This helps it firm up for cleaner servings.
