How to Freeze Corn on the Cob

Updated: Mar. 07, 2024

This is how to freeze corn so your harvest (or purchase from the farmers market) will last long after peak season.

There’s nothing like enjoying fresh corn on the cob in summer. However, fresh corn stored in the fridge will only last for one to two days—so if you know you won’t put it to use within that timeframe, knowing how to freeze corn guarantees that none of those precious kernels go to waste. Plus, freezing corn means you can indulge in your favorite ways to eat corn on the cob and fresh corn recipes even after corn season has come and gone.

Read on for the best methods to save fresh corn!

How do you prepare fresh corn for freezing?

No matter which method you choose, you’ll need to shuck your corn before freezing—unlike storing fresh corn, which requires leaving the husks on.

You’ll also want to grab some freezer bags and a permanent marker (to write the date on the bag).

How to Freeze Corn

How to freeze fresh corn on the cob

If you want to freeze corn on the cob, you can either freeze it fresh or freeze after blanching the corn. Blanching is a traditional cooking method used to keep fresh produce for longer periods of time. Blanching vegetables also helps remove dirt and keeps them vibrant. In the case of corn, the kernels will stay bright, yellow and juicy as can be.

Follow all the steps through if you plan to blanch the corn before freezing, or skip steps 2 and 3 if you would rather freeze the corn fresh.

Step 1: Shuck the corn

Start by shucking the corn and removing its silk.

Step 2: Blanch the corn

Bring a large pot of water to a boil. Place the shucked corn cobs into the boiling water to blanch them. It should take 7 minutes for small cobs, 9 minutes for medium cobs and 11 minutes for large cobs.

Step 3: Place the corn cobs in an ice bath

After boiling them, remove the cobs from the pot and immediately place them into ice water for the same length of time. Remove the corn from the ice water and pat dry with paper towels.

Step 4: Store the corn cobs

Whether you’ve blanched the corn or not, place the corn cobs into freezer bags and push any air out. You’ll want to date the airtight freezer bags using a permanent marker before placing the bags into the freezer.

If you prefer corn off the cob, you can cut the kernels off and pour them into freezer bags instead.

After shucking and removing the silk from the corn, cut the kernels off of the corn cob and dump them into a bowl or container. Then, pour the corn kernels into as many freezer bags as needed and push any remaining air out. Date the airtight freezer bags with a permanent marker, then place the bags into the freezer.

Editor’s Tip: When freezing corn kernels, make sure you allow enough space for the kernels to breathe. We recommend freezing kernels in a single layer.

How long does corn last in the freezer?

Whether in cob or kernel form, corn should last about six months stored in an airtight freezer bag.  If you have leftovers after employing your favorite method for how to cook corn on the cob, you can pop those in the freezer as well. Simply tuck the cooled, cooked corn into freezer bags. Just know that cooked corn may be a little mushier when you reheat it than corn that was blanched or frozen fresh.

When it’s time to enjoy the corn after storing in the freezer, there are plenty of methods for reheating corn on the cob. Depending on how much time you have, try your microwave, oven, stovetop, air fryer or even the grill.
