Put the trivet in the Instant Pot liner. Pour in the water.
Set the eggs on the trivet in a single layer. Overlapping or stacking can lead to cracked eggs.
Lock the lid and set the vent to sealing. Press the pressure cook button and set the time to 9 minutes. When the time is up, manually release the pressure right away.
Set the eggs in a bowl of cold water to cool for 5 minutes. Transfer to the refrigerator if not using right away, or peel and eat.
Notes
You can cook as many or as few eggs as you like. I've even cooked only 1 egg.
For a soft, slightly runny yolk, cook for only 3 minutes.
Stack the eggs might cause them to crack, but it usually doesn't negatively affect the outcome.
You can put the eggs in an ice bath to cool them quicker, but I find that leads to a very difficult to peel egg. Let it cool naturally or in cold water.
