1. Preheat Oven

Heat your oven to 375°F (190°C).

2. Cook Meat

In a large skillet over medium-high heat, add olive oil. Cook the ground beef until browned, breaking it apart as it cooks. Drain excess fat if needed.

3. Sauté Vegetables

Add onion, bell peppers, and mushrooms to the skillet. Sauté for 5–6 minutes until softened. Stir in garlic and cook for 1 more minute.

4. Season & Combine

Stir in salt, pepper, Worcestershire sauce, and beef broth. Let it simmer for 2–3 minutes to combine flavors.

5. Make It Creamy

Lower heat and stir in the cream cheese until smooth. Ensure it’s well combined with the meat and veggies.

6. Assemble Casserole

Transfer the mixture to a lightly greased 9×13-inch baking dish. Sprinkle evenly with mozzarella, provolone, and oregano over the top.

7. Bake

Bake uncovered for 15–20 minutes. Look for the cheese to be melted and bubbly.

8. Serve

Garnish with chopped parsley if desired. Serve hot with crusty bread, over rice, or with a side salad.
