Ingredients

• 1½ pounds ground beef or thinly sliced steak

• 1 tablespoon olive oil

• 1 green bell pepper, sliced

• 1 red bell pepper, sliced

• 1 medium onion, sliced

• 1 cup mushrooms, sliced (optional)

• 2 cloves garlic, minced

• 1 teaspoon Worcestershire sauce

• Salt and black pepper to taste

• 4 slices provolone cheese (or 1½ cups shredded provolone/mozzarella)

• 4 ounces cream cheese, softened

• ½ cup heavy cream (optional, for extra creaminess)

Tip: Ribeye steak gives the most authentic flavor, but ground beef works great for convenience.

Instructions

1. Preheat the Oven

Preheat your oven to 190°C (375°F) and lightly grease a casserole dish.

2. Cook the Beef

Heat a large skillet over medium-high heat. Add the ground beef or sliced steak and cook until browned. If using ground beef, break it apart as it cooks. Drain excess fat if necessary.

3. Sauté the Vegetables

In the same skillet, add olive oil. Cook the sliced onions, bell peppers, and mushrooms (if using) for about 5–7 minutes until softened. Add minced garlic and cook for another 30 seconds.

4. Combine Ingredients

Return the cooked beef to the skillet with the vegetables. Stir in Worcestershire sauce, salt, and pepper. Mix well to combine all the flavors.

5. Add Creaminess

Lower the heat and stir in the cream cheese until melted and evenly distributed. If you prefer a creamier casserole, add heavy cream and stir until smooth.

6. Assemble the Casserole

Transfer the mixture into the prepared casserole dish. Spread it evenly. Layer the provolone cheese slices on top or sprinkle shredded cheese evenly over the surface.

7. Bake

Place the casserole in the oven and bake for 15–20 minutes, or until the cheese is melted, bubbly, and slightly golden.

8. Serve

Remove from the oven and let it rest for 5 minutes before serving. This helps the casserole set and makes it easier to portion.
