  • 1 cup water (for the pressure cooker)
  • 2 lbs Russet Potatoes (about 5 medium potatoes)
  • 4 Tbsp Butter
  • 1 1/4 tsp Kosher Salt (or 1 tsp table salt)
  • 2/3 cup Half and Half (or whole milk)


  1. Put the water into the inner liner of the Instant Pot.

  2. Scrub the potatoes, or peel them, if you prefer. Cut each potato into fourths.

  3. Put the potatoes in a steamer basket or steamer rack. Set the basket or rack into the pot.

  4. Close the lid and lock it into position. Set the Steam Release Knob to the Sealing position.

  5. Set to Pressure Cook (Manual), and use the +/- button or dial to choose 8 minutes.

  6. When the cook cycle ends, do a Quick Release of the pressure by turning the steam release knob to Venting (on the Ultra, just press the steam release button).

  7. When all of the steam is out and the pin in the lid drops, open the lid and remove the basket or rack of potatoes (very carefully) and transfer potatoes to a bowl.

  8. Add the butter and use a potato masher to incorporate the butter as well as mash the potatoes. Try not to over mash them.

  9. Add the salt and cream, then use a spoon to continue mixing to the desired consistency. Add more cream or milk as desired.

  10. Taste and adjust salt, if necessary.

  11. Serve hot.
