Storage & ReheatingStore in the fridge for up to 4 days. Allow to cool completely before sealing containers. Freezing isn't recommended — the potatoes and cream sauce can turn watery and grainy once thawed. Reheat in the microwave for 2-3 minutes until piping hot throughout, stirring halfway. For a crispier top, reheat in the oven at 180°C (350°F) for 10-12 minutes uncovered.
