  • Step 5: In a large bowl, mix the cooked pasta, sautéed chicken, and Alfredo sauce until well coated. Transfer to a greased 9x13 inch baking dish.
  • Step 6: Sprinkle the remaining 1 cup of mozzarella cheese over the top of the casserole.
  • Step 7: Preheat the oven to 350°F (175°C) and bake for about 25-30 minutes or until the cheese is bubbly and golden brown.
  • Step 8: Remove from the oven, let cool for a few minutes, and garnish with freshly chopped parsley before serving.
