Step-by-Step Instructions

Start by preheating your oven to 375°F (190°C). Grease a casserole dish lightly and set aside.

Heat olive oil in a large skillet over medium heat. Add sliced onions and bell peppers, then sauté for about 5–7 minutes until softened and slightly caramelized.

Add garlic and cook for another 30 seconds until fragrant.

Add the ground beef or thinly sliced steak to the skillet. Cook until browned and fully cooked, breaking apart the meat if using ground beef.

Season with Worcestershire sauce, Italian seasoning, salt, and black pepper. Stir well to combine all the flavors.

Reduce heat slightly and add cream cheese along with heavy cream or milk. Stir until the mixture becomes creamy and smooth.

Transfer the beef mixture into the prepared casserole dish and spread evenly.

Top generously with shredded provolone or mozzarella cheese.

Bake uncovered for about 15–20 minutes until the cheese is melted, bubbly, and slightly golden on top.

Remove from the oven and let it rest for a few minutes before serving.

Serve hot on its own or with toasted bread, pasta, or rice.
