Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave with a splash of chicken broth or milk to restore creaminess. This casserole can be assembled the night before, covered tightly, and refrigerated unbaked. Add 10 extra minutes to the covered baking time if going straight from the fridge to the oven. For a crispier topping, broil for the final 2 to 3 minutes after removing the foil.
