  1. Place potatoes in Instant Pot. Add enough water to cover them by about 1".
  2. Close the lid. Set the valve to "sealing".
  3. Press MANUAL button. Press the +/- button to set to 7 minutes. The IP will start cooking.
  4. When the pressure cooker beeps, carefully turn the valve to vent ( this is called quick pressure release).
  5. Drain the potatoes and return to the IP insert or place in a mixing bowl. Add half and half, salt and pepper and if desired, dill or chives and sour cream. Mash with a potato mashed to desired texture.

Recipe Notes

I used russet potatoes as I like the texture the best. You can use Yukon gold or red potatoes too but the texture will be slightly different, thicker and not as fluffy.

The cooking time includes the time the IP needs to come to pressure. For me that was about 5 minutes.
