Store in an airtight container and keep in the refrigerator for up to 4 days. They also freeze well! Once they have cooled, transfer the lima beans to a sealed freezer-safe zipper bag or container, and keep them in the freezer for up to 6 months. Let them defrost overnight before reheating on the stovetop or in the microwave. You might need to add a splash of water or stock to get them back to the right saucy consistency.
