Can I make this dish ahead of time?
Yes. Assemble the chicken on a baking sheet, cover, and refrigerate up to 8 hours before baking. Add 2–3 minutes to bake time if starting cold. The cooked pasta is best served fresh, but leftovers store well.
How do I know when the chicken is done?
Bake until the Parmesan topping is golden and an instant-read thermometer inserted in the thickest piece reads 165°F (74°C).
What can I substitute for mayonnaise?
Use sour cream or Greek yogurt mixed with a little olive oil for a tangier crust, though texture and richness will differ slightly.
Can I use a different pasta shape?
Yes. Fettuccine, penne, or linguine work well with the garlic butter cream sauce. Cooking time may vary slightly.
How do I reheat leftovers?
Warm chicken in a 350°F oven for 8–10 minutes covered. Reheat pasta gently on the stovetop with a splash of milk or water to restore creaminess.
