Can I use chicken breasts instead of thighs?
Yes, but thighs stay moister and more flavorful. If using breasts, reduce baking time by 5–10 minutes to prevent drying out.
How do I prevent the casserole from drying out?
Don't overbake. The cheese sauce keeps the dish moist; cover with foil if the top browns too quickly.
Can I make this ahead?
Yes. Assemble the casserole, cover, and refrigerate up to 24 hours. Add 10–15 minutes to baking time if baking from cold.
What type of cheese works best?
Sharp cheddar melts smoothly and adds flavor. A blend of cheddar and mozzarella creates creaminess and stretch.
Can I freeze leftovers?
Yes. Store in an airtight container for up to 3 months. Thaw overnight and reheat covered at 350°F until warmed through, about 20–30 minutes.
