How Long Does Corn on the Cob Last? A Comprehensive Guide to Fresh and Cooked Storage

Corn on the cob is a summertime staple, but how long does it last? Whether you’re storing fresh or cooked corn, proper storage techniques are crucial to maintain its freshness and quality. This comprehensive guide will provide you with all the necessary information to ensure your corn on the cob remains at its best.

Fresh Corn on the Cob: Maximizing Shelf Life

Fresh corn on the cob has a relatively short shelf life, typically lasting between 1 to 3 days in the refrigerator. To extend its lifespan, follow these tips:

  • Keep the Husks On: The husks help protect the corn from moisture loss and spoilage. Leave the husks intact until you’re ready to cook or eat the corn.

  • Refrigerate Promptly: Refrigerate fresh corn on the cob as soon as possible after purchase. Store it in the refrigerator at a temperature of around 32-40°F (0-4°C).

  • Wrap Unhusked Corn: If you’ve already removed the husks, wrap the uncooked corn tightly in plastic wrap or aluminum foil before refrigerating. This will help prevent moisture loss and extend its shelf life.

Cooked Corn on the Cob: Refrigeration and Freezing

Cooked corn on the cob has a slightly longer shelf life than fresh corn, but it’s still important to store it properly to maintain its quality.

  • Refrigeration: Store cooked corn on the cob in an airtight container or wrap it tightly in plastic wrap or aluminum foil. Refrigerated cooked corn will last for 3 to 5 days.

  • Freezing: Cooked corn on the cob can also be frozen for longer storage. Cut the kernels off the cob and place them in an airtight freezer-safe container or bag. Frozen corn kernels will last for 10 to 12 months.
