Store Crockpot Ham and Bean Soup in airtight containers within 2 hours of cooking. Refrigerate for up to 4 days. Freeze for up to 3 months in freezer-safe containers, leaving about 1 inch of space for expansion. Label each container with the date so you can rotate older batches first. Reheat refrigerated soup over medium-low heat until it reaches 165°F, stirring every 2 to 3 minutes. Add 2 to 4 tablespoons of chicken broth or water if it has thickened too much. Discard the soup if it develops a sour smell, bubbles while cold or any visible mold.
