  • Pressure Cooker


  • 5 pounds potatoes, washed

  • 2 teaspoons seasoning salt


  • Place the potatoes and water in the Instant Pot.
  • Secure the lid and set the valve to sealing. Select manual setting for 10 minutes.
  • When its done, you can do manual release right away, or just forget about it for hours. After the pressure has released, drain the little bit of water, add the butter and let it melt.
  • Stir in the milk and seasoning salt of your choice. (Its going to vary a bit in saltiness so make sure to taste them.)
  • Mash them well, taste for salt, put the lid back on and let the magical keep warm setting keep it warm for you!

  1. Hey Kate! Your recipe works perfectly — before this I’ve been disappointed with Ippy mashed potato recipes! If you want to make mashed potatoes with the Ippy and then freeze them, you can sub the butter and milk with 8 ounces cream cheese and an egg. Mash in the cream cheese first, and then the egg (the potatoes are still hot enough to avoid the risk of raw egg). Put them into freezer-to-oven safe casserole dish (full recipe fits into a 3 quart or 9×13), cover, and freeze. To reheat, thaw completely and then bake for 35-40 minutes at 375°F, until top is golden. They don’t have to be frozen, either, they can be made a day or two ahead, refrigerated, and then reheated as if from defrosted. Combining your Ippy method for the potatoes (including seasoning salt) with the make ahead method leaves the Ippy available if you want to use it to make a good beef stew or need it for other dishes.

  4. I usually hate making mashed potatoes but this is so hands off it’s great. I don’t have to watch a pot to constantly check if they are done!

  5. Love these! We make them regularly- but today on US thanksgiving, i had a whole extra burner free thanks to this recipe!

  6. This is the only way I make mashed potatoes now! I love that I can start them ahead of time and then mash right before serving!

  7. I make these with vegan butter and milk but the times and amounts are perfect. So easy because you can make it all in one pot and keep it warm. I love my IP!!

  8. Never misses! Perfect potatoes with less of the effort…EVERY TIME! Don’t shirk on the suggestion of the wild mushroom seasoning! I also like to add garlic and served with chopped onions on top.

  9. The only way we make mashed potatoes now. Love that you can make them ahead and they are ready to go for dinner time.
