Shuck the corn (more tips on this in the blog post).
Add one cup of water to the bottom of your pressure cooker and insert the metal steam rack (trivet). I usually use cold water for ease. If you use hot water, the Instant Pot will come to full pressure in only a few minutes.
Place the ears of corn on the stand and seal the lid, ensuring the venting knob is in the sealing position. Place them in alternating directions if you're cooking enough corn to have them in layers. This helps the air circulate around the corn and ensures they cook evenly.
Select "Pressure Cook" (if there are different options) on MANUAL (high pressure) mode and cook for 2-3 minutes.
Once cooked, use a kitchen towel to carefully use the quick release (turn the venting knob to the venting position) to release the remaining steam in the pressure cooker. Once the floating valve drops, carefully open the lid, use tongs to retrieve the pressure cooked corn, and enjoy!
Instant Pot Frozen Corn on the Cob
If the corn has been husked and blanched, I recommend cooking it for 4 minutes and waiting a few minutes before releasing the quick release. If it hasn't been blanched, then it may need 5 minutes.
Make ahead/Store: Once prepared, you can store the cooled Instant Pot corn on the cob in an airtight container for 3-5 days. Freeze: Flash freeze the cooked cobs, not touching, until solid, then transfer to a Ziplock and store for 6 months. You can also remove the corn kernels and freeze just them in a Ziplock bag, with excess air removed. Reheat: Reheat the corn either in hot water (with a lid) for 2-3 minutes or wrapped in a damp paper towel and microwaved in 15-20 second intervals.
Use fresh corn: The fresher the corn, the sweeter and juicier it will be. Use organic where possible, too, for the most flavor.
Times may vary: Based on the size of your ears of corn and how tender you like your corn. For example, for tender-crisp results, 2 minutes may be enough for you. I recommend starting with the lower time as it's fairly easy (and quick) to bring the pot back up to pressure if you need to add an extra minute.
Use hot water to save time: If you use hot water in your Instant Pot, it will take less time to reach full pressure.
If the corn is too long: If it's only slightly too long, you can just trim the stem end. Otherwise, chop the cobs in half.
If you don't have a trivet: Use a steamer basket or rolled-up balls of foil.
