Notes

  • Store any leftover casserole in an airtight container in the refrigerator for up to 3 days or freeze it for up to 2 months. To reheat, microwave the portion in a microwave-safe bowl for 1 minute, then stir and heat again until warmed through. Alternatively, warm leftovers in a preheated oven until hot.
