Place the water inside a 6-quart Instant Pot, add the steam rack and then gently place up to 12 eggs on the rack spread out.
Place the lid on and move the valve to sealing. Press manual pressure and set the timer to 4 minutes high pressure. You’ll notice the Instant Pot will start to come to pressure first and then the timer will begin. It can take 8-10 minutes to come to pressure.
When the cook time is up, let the pressure release naturally for 4 minutes, then do a quick release for any remaining pressure. Carefully open and remove the lid.
Remove the eggs from the Instant Pot and place them in an ice water bath for 4 minutes.
Remove the eggs from the water bath and store in the fridge.
Note: You do not need to change the cooking time based on the number of eggs in the pot. If you have an 8qt IP and can fit 18 eggs, you'll still use the 4-4-4 method.
