Wash and scrub the russet potatoes. Pierce each potato a few times using the tines of a fork.
Place a metal trivet at the bottom of the Instant Pot. Pour in the cup of water. Then place the russet potatoes on the trivet. Close the lid placing the valve to"sealing".
Select "manual" on high pressure for 13 minutes (for small), 15 minutes (for medium) and 18-20 minutes (for large). Once the timer is done let the Instant Pot come down to pressure for 15 minutes. Then, carefully force pressure.
Using tongs, remove the potatoes out of the Instant Pot. Using a fork, prick open the potato, fluff with the fork tines, top, and enjoy.
Notes
Try to cook the same size potatoes. This will ensure that all potatoes are cooked through.
Small Potatoes take about 12 minutes in the Instant Pot, Medium take 14 minutes, and large take about 16-18 minutes.
Stack the potatoes on top of one another–it will not mess with the cooking time.
Use a trivet on the bottom of the Instant Pot so they don’t burn/get soggy and/or stick to the bottom.
No need to wrap the potatoes in foil!
Save your flavored broth–no difference in flavor for steaming.
