To Bake Later: Assemble the baked rigatoni up to one day in advance, cover, and refrigerate. Before baking, let it sit at room temperature for about 20 minutes to reduce the chill, then add 15-20 minutes to the covered baking time.
To Freeze: You can freeze the unbaked rigatoni for up to 3 months. Wrap it tightly with plastic wrap and freeze in an oven-safe dish. Thaw in the refrigerator for 24 hours before baking, then follow the baking instructions for a chilled casserole.
Leftovers can be stored in an airtight container in the fridge for up to 3-4 days. Reheat in the microwave or in a covered dish in the oven until warmed through.
