1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish and set aside.
2. In a large skillet over medium heat, add the olive oil. Sauté the onions and bell peppers until they are soft and fragrant, about 5-7 minutes.
3. Add the minced garlic to the skillet and cook for an additional minute. Remove the vegetables from the skillet and set aside.
4. In the same skillet, brown the ground beef, breaking it apart with a wooden spoon until fully cooked. Drain any excess fat.
5. Return the sautéed vegetables to the skillet with the cooked beef. Stir in the Worcestershire sauce, salt, and pepper. Cook for another 2 minutes to combine the flavors.
6. Reduce the heat to low and add the cream cheese to the skillet, stirring until melted and smooth. Gradually add the beef broth, stirring until the mixture is well combined.
7. In a large bowl, combine the cooked pasta with the beef and vegetable mixture. Transfer this mixture into the prepared casserole dish.
8. Top the casserole with shredded provolone and mozzarella cheese, spreading evenly over the top.
9. Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden brown. Let it cool slightly before serving.
