A rich and indulgent pasta bake featuring tender steak, creamy blue cheese sauce, and a golden mozzarella topping—perfect comfort food.
1. Bring a large pot of salted water to a boil and cook rigatoni until al dente, then drain and set aside.
2. Heat olive oil in a large skillet over medium-high heat and sear steak pieces for 3–4 minutes until browned but not fully cooked. Remove and set aside.
3. In the same skillet, cook diced onion and bell pepper until softened, about 5 minutes. Add garlic and cook for 1 minute.
4. Reduce heat to medium and pour in heavy cream, stirring to deglaze the pan.
5. Stir in blue cheese, oregano, salt, and black pepper, cooking until the cheese melts and sauce thickens.
6. Return steak to the skillet and add cooked rigatoni, tossing to coat evenly.
7. Transfer mixture to a greased baking dish and top with shredded mozzarella.
8. Bake at 375°F (190°C) for 15–20 minutes until cheese is melted and golden.
9. Remove from oven, sprinkle with fresh parsley, and serve hot.
Use well-marbled steak for best flavor and tenderness.
Let steak rest briefly after searing to retain juices.
Substitute half-and-half or milk with Greek yogurt for a lighter sauce.
Store leftovers in the refrigerator for up to 3 days and reheat covered.
