Keeping Corn on the Cob: Three Methods

One of the best parts of summer is eating fresh corn right off the cob, so it's only natural that you'd want to know how to keep it fresh once you've bought it.

  1. 1

    Don't remove the husks. The corn remains fresh and moist inside the husks. Corn can dry out if the husks are removed prior to storage. You shouldn't even bother peeling back the husks, if possible. [1]

    • Husked corn should be used within two days.
    • Look for ears of corn with green husks and silk that is still moist to purchase without having to peel back the husks. Every part of the cob, from the tip to the base, should be firmly attached to the ground. Verify that there are no pinprick-sized holes in the corn, as these are signs of worm infestation. Only peel the husk at the very top to check if the kernels extend to the very tip. [2]

    Put them in a plastic bag and seal it. Keep the corn unwashed. They should be stored in a large zip-top bag with as little air as possible between the contents. Place the bag in the crisper bin of your fridge for the vegetables. [3]

    Prepare food within a week. If you leave your corn out for more than 5 to 7 days, it will begin to spoil. Corn loses flavor and moisture over time, so it's best to cook it as soon as possible for the best taste and texture. [4] Try to get it cooked in 3 days. [5]

    Verify the expiration date and ensure the product is still fresh. Mold will first appear on the tips of ears of corn. If you find a moldy or discolored tip, you can discard that section plus an additional inch (2 cm). 5 cm) If the entire cob, however, appears moldy, you should toss it. [6]

    • Moldy corn usually darkens in color and loses their shape when eaten. Fuzzy, white or blue corn growth is also possible.

    It's time to separate the kernels from the hulls. The husks must be removed before corn can be frozen. This is because, prior to being frozen, you typically either blanch it or remove the husk. It's also tricky to remove the husk from frozen corn. [7]

    • You can keep frozen corn for up to a year.

    Corn on the cob can be preserved by blanching and freezing whole ears. Whole ears can be blanched by placing them in a pot of boiling water for 7-11 minutes, depending on their size. Immediately after you take them out of the water, you should submerge them in ice water for 30 seconds. Eliminate any surplus liquid. [8]

    • The corn should be frozen in airtight containers or freezer bags. It's important to remove as much air from a bag as possible before closing the zipper.
    • If you prefer, you can reduce the cooking time. If you cook the corn for a shorter period of time before freezing it, it will be crunchier when you thaw it.

    It's recommended to blanch and freeze kernels before storing them in the freezer. Submerge the ears in boiling water for a moment to blanch them. Cook them in boiling water for 2 1/2 minutes. It's up to you if you want to cook them for a shorter or longer amount of time. Grab them and submerge them in a tub of ice water. Excess water should be drained. [9]

    • Get out your knife and separate the kernels. To freeze the kernels, store them in airtight containers or freezer bags. When using bags, make sure all the air is sucked out.

    For quicker freezer preparation, freeze the kernels unblanched. The kernels themselves can be frozen separately. Cut the corn off the cob. First, store the kernels in freezer-safe containers such as zip-top bags or airtight containers. When using freezer bags, squeeze out as much air as possible. [10]

  5. 5

    If the corn is frozen, defrost it before warming it or cook it in the microwave. Blanched corn can be frozen and eaten after defrosting in the fridge overnight. Both raw and blanched corn can be easily heated in the microwave.

    • Put it in the microwave and use the defrost function. Put in your corn's weight in pounds. Check the corn's weight again after 2 minutes if you are unsure.

    Store the ears as a whole in a sealed bag. The best way to preserve any leftover corn is in an airtight container. If you prefer, you can also place it in a plastic bag with a zipper. Squeezing as much air out of the zip-top bag will help keep the corn fresher for longer. [11]

    If you like, you can remove the corn from the cob. Cut the kernels off the cob and use them in another recipe. Once they've been cut, store them in the fridge in an airtight container. A zip-top bag, with the air squeezed out, can also be used. [12]

  3. 3

    Take a bite out of that in three to five days. As soon as you cook corn on the cob, its shelf life increases by a few days. After being cooked, the food can be consumed up to five days after its original sell-by date has passed. However, once refrigerated, it should be consumed within 5 days. [13]

    • Corn that has developed a musty odor or mold should be thrown away.
    • Corn is a good example of a food that can be reheated in the microwave. Give it a minute to start, and then see if more is required.

  • Question

    Can I freeze sweet corn straight from the garden without blanching it first?

    Community Answer

    It's possible, yes. We pick them fresh from the garden, clean, husk, and freeze them. We cook them in a pot of boiling water whenever we want to eat them. And they won't go dry, so that's a bonus. Freezer burn can be avoided by using vacuum-seal bags.

  • Question

    What's the best way to keep shucked corn fresh?

    Community Answer

    Freezing is the best way to preserve ears of corn after they have been shucked. Corn blanching is optional but recommended. Taking the kernels off the cob and freezing them is a great alternative to blanching. Either way, you can store corn in the freezer by placing it in a Ziploc bag, pressing out as much air as you can with a straw, and then placing the bag in the freezer. Put the corn on a sheet pan lined with parchment paper and freeze it for later use. Layer the corn and freeze until solid; then store in the freezer. Take out only as much corn as you need when you're ready to use it, and the rest can stay in the freezer for later.
