Notes

Slightly undercook the pasta to prevent it from becoming soft after freezing and reheating.
Freshly grated parmesan provides the best flavor and melting quality.
Chicken thighs can be substituted for chicken breasts for a richer casserole.
Add steamed broccoli, spinach, or peas for extra vegetables.
For a crispier topping, broil for 2–3 minutes before serving.
Store leftovers in the refrigerator for up to 4 days.
Freeze individual portions for convenient postpartum meals and quick lunches.
This casserole can be assembled up to 48 hours in advance and refrigerated before baking.
