Do I need to cook the pasta first?
No. The uncooked penne cooks directly in the sauce and broth in the oven, which is what makes this a true dump-and-bake recipe.
Can I use fresh chicken instead of rotisserie?
Yes, but increase baking time by 15–20 minutes to ensure the fresh chicken reaches 165°F internal temperature.
How do I store leftovers?
Cover and refrigerate up to 3 days. Reheat in a 350°F oven for 15–20 minutes until heated through, or microwave individual portions.
Can I make this ahead?
Yes. Assemble in the baking dish, cover tightly, and refrigerate up to 24 hours. Bake from cold, adding 10–15 minutes to the baking time.
What if my sauce is too thick after baking?
Stir in a splash of chicken broth or pasta water. The pasta continues to absorb liquid as it sits, so slight looseness when first baked is normal.
