Ingredients
  

Pasta and Chicken
  • 1 lb rotini pasta (or penne, rigatoni)
  • 2-3 cups cooked chicken, diced or shredded Use rotisserie chicken to save time.
Sauces
  • 1 jar Alfredo sauce (about 15 oz)
  • 1 jar garlic Parmesan sauce (about 15 oz)
Cheeses
  • 2 cups shredded mozzarella cheese
  • 1 cup grated Parmesan cheese
Seasoning and Garnish
  • Salt and pepper, to taste
  • Fresh parsley, chopped (optional) Garnish before serving.

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C).
  2. Boil the rotini to al dente. Salt the water and cook until the pasta gives a little bite. Reserve 1 cup of the hot pasta water, then drain.
Mixing
  1. In a large bowl, combine the hot pasta, shredded chicken, Alfredo, and garlic Parmesan sauce.
  2. Add half the mozzarella and half the Parmesan. Stir until everything looks creamy. If it feels thick, add the reserved pasta water a little at a time.
Baking
  1. Season with salt and pepper. Adjust to taste. Transfer the mixture into a lightly greased 9x13-inch baking dish and spread it evenly.
  2. Sprinkle the remaining mozzarella and Parmesan across the top.
  3. Cover with foil and bake for 20–25 minutes until the filling bubbles at the edges and the cheese melts.
  4. For a golden top, broil uncovered for 2–3 minutes—watch closely so it doesn’t burn.
Serving
  1. Let it rest for 5 minutes. Garnish with chopped parsley, slice, and serve warm.
