If you like to buy corn on the cob in bulk, but dread the idea of eating every last morsel before it goes bad, then knowing the best method for storing corn on the cob is in order. But whether you go with the fridge or the freezer, the key to keeping this tasty vegetable fresh is to act quickly.


You can store corn on the cob in the refrigerator for two to three days or in the freezer for up to 10 months.

Storing Corn on the Cob

The difference between sweet corn and kernels that lack flavor is often attributed to the method used for storing corn on the cob. That's because an ear of corn will lose up to 50 percent of its sugar when left at room temperature, according to the Academy of Nutrition and Dietetics. So, unless you want bland-tasting corn, keep it in the fridge. For maximum flavor, get it in the fridge right away and eat within two days.

The corn on the cob storage method you choose depends on when you plan on eating your corn. If you want to serve it within a few days, then the fridge is the best option. To ensure freshness, follow these steps from the University of Missouri Extension.

  1. Leave the corn in the husks.
  2. Remove long shanks.
  3. Store in the refrigerator uncovered for two to three days.
  4. Remove, rinse off, cook and eat.

Freezing Corn on the Cob

If your meal plan for the week doesn't include corn on the cob, you may want to consider the freezer method.

To freeze corn on the cob, Utah State University Cooperative Extension recommends the following steps:

  1. Blanch the corn by placing several ears into a gallon of boiling water. Blanching time will vary depending on the size of the ear. Small ears blanch for seven minutes, medium ears for nine minutes and larger ears for 11 minutes.
  2. Chill the ears of corn in cold water until they are cool, anywhere from seven to 11 minutes.
  3. Drain the water.
  4. Wrap each ear in freezer foil or film.
  5. Place the ears of corn in a freezer bag and label with the date. You can also use this method for freezing sweet corn in the husk. Just wrap corn on the cob in a freezer-safe container.
  6. Get rid of excess air and seal.
  7. Store in freezer at zero degrees Fahrenheit or lower.

Safety Tips for Storing Corn

Preserving taste and freshness and following proper food safety guidelines are often equated with meat, poultry and dairy products. But the process you use to prep and store vegetables such as corn is just as important.

Your first order of business is to check the temperature of your fridge and freezer. The U.S. Food and Drug Administration (FDA) says one of the best ways to prevent bacteria from invading your food is to keep your appliances at the proper temperature. For the fridge, make sure the temp is set at or below 40 F. The freezer temperature should be zero F.

If you've had corn in the fridge longer than two or three days, the FDA says to be on alert for anything that looks or smells suspicious. This includes keeping an eye out for changes to the corn that may indicate that it's spoiled. When storing corn on the cob in the freezer, you can safely store it at zero F for 10 months.
