Freezer

For freezer storage, use plastic containers or glass jars designed for freezing. Make sure mashed potatoes are completely cooled before freezing, and leave headspace to allow for expansion. Divide leftover potatoes into portion sizes for easier reheating. Label containers with date and contents before freezing. Mashed potatoes will maintain best quality frozen for 2-3 months but are safe to consume within one year.
