Directions

  1. Preheat oven to 375°F. Lightly grease a 9×13-inch casserole dish. 
  2. Bring a large pot of salted water to a boil. Cook rigatoni 2 minutes less than package directions for al dente. Drain and set aside. 
  3. Meanwhile, melt butter in a large skillet or Dutch oven over medium heat. Add sliced TX1015 Sweet Onion and season lightly with salt and pepper. Reduce heat to medium-low and cook for 15–20 minutes, stirring frequently, until onions are soft and caramelized. 
  4. Stir in thyme and Worcestershire sauce. Pour in beef broth and simmer for 3–4 minutes to combine flavors. 
  5. Reduce heat to low and stir in heavy cream along with ½ cup Parmesan cheese. Stir until smooth and creamy. 
  6. Add cooked rigatoni to the skillet and toss until evenly coated. 
  7. Transfer pasta mixture to prepared casserole dish. Top with remaining ½ cup Parmesan cheese and mozzarella cheese. 
  8. Bake uncovered for 15–20 minutes, or until hot and bubbly with a lightly golden top. 
  9. Garnish with fresh parsley before serving.
