Top Tips & FAQ
How long do you cook frozen corn on the cob in the Instant Pot?
Cook frozen corn on the cob on high pressure for 4 minutes. Once the cooking time is up, do an immediate quick release for the best texture.
Can you cook corn on the cob without a trivet?
Yes, you can cook corn on the cob without a trivet if you have enough water in the pot. A trivet helps keep the corn elevated so it steams evenly and prevents burn warnings. If you don’t have one, you can place the corn directly in the water, use a silicone steamer basket with handles, or even use canning jar rings to lift the corn off the bottom.
Can you add butter when cooking corn in the Instant Pot?
Yes. Stand the corn on end and place a small pad of butter on top of each ear. As it cooks, the butter melts down the corn, coating it as it steams.
Can you cook corn on the cob with the husk on?
Yes, you can cook corn with the husk on. Add 1 to 2 minutes to the cook time and the silk will be easier to remove after cooking.
How much corn fits in a 6 qt Instant Pot?
A 6 quart Instant Pot will fit about 6 to 7 ears of corn. You can stack them or cut them in half to fit more.
Why use the Instant Pot instead of boiling corn?
It’s faster, doesn’t heat up the kitchen, and gives you a more consistent, tender texture.

Side Dish Recipes
A few of my favorite recipes that pair perfectly with corn at summer cookouts:
How to Freeze Corn on the Cob
If you have a large batch of fresh corn, freezing it is an easy way to enjoy it year-round. Blanching helps preserve the color, flavor, and texture by stopping the natural enzymes that cause corn to break down over time.
Bring a large pot of water (about 6 to 8 quarts) to a boil.
Remove the husks and silk, and cut large ears in half if needed.
Working in batches, submerge the corn in boiling water and blanch for 4 minutes.
Immediately transfer the corn to an ice bath and let it cool for 4 minutes.
Drain well, then place the corn into freezer-safe bags.
Vacuum seal if possible, label, and freeze.
For best quality, use within 8 to 12 months.
How to Store Fresh Corn on the Cob
If you plan to use your corn right away, you can leave it in the husk at room temperature for a short time.
For longer storage, keep unshucked corn in the refrigerator crisper drawer for up to 2 days.
If you need to store it longer, remove the husk and silk and place the corn in a large zip-top bag in the fridge until ready to use.
After a couple of days, the silk can start to brown and become slimy, which can affect the quality of the corn.
How to Store and Reheat Leftovers
Store leftover cooked corn on the cob in an airtight container in the refrigerator for up to 3 days.
To reheat, wrap the corn in a damp paper towel and microwave for 30 to 60 seconds, or until heated through.
You can also cut the corn off the cob and freeze it for later use in soups, casseroles, or quick side dishes.
