Put the trivet or steaming basket inside the Instant Pot and place the shucked ears of corn on top.
Pour in the water and secure lid. Switch the valve to the sealing position.
Cook on high pressure/manual for 2 minutes.
Allow the pressure to release naturally for 5 minutes. Then switch the valve to the venting position for the remaining pressure.
Transfer the corn to a serving platter and enjoy!
Notes
It takes 5 to 10 minutes for the Instant Pot to come to pressure. After that, you will see the cooking time counting down from 2 minutes. Store leftover corn in an airtight container in the refrigerator for 2-3 days.
