You can keep leftover pozole for up to 3 days in an airtight container in the refrigerator. To reheat on the stove transfer pozole to a saucepan and heat over medium-low heat, stirring occasionally for about 10 minutes. To reheat in the microwave transfer to a microwave-safe dish, cover with a microwave-safe lid or paper towel, and heat for about 2 minutes stirring every 30-seconds.
