When storing leftovers, place them in an airtight container in the fridge for up to 3 days. For freezing, allow the mashed potatoes to cool completely before transferring them to a freezer-safe container, where they can last for up to 2 months. Reheat gently on the stovetop or microwave, adding a splash of buttermilk to restore creaminess.
