Instant Pot Mashed Potatoes

Instant Pot Mashed Potatoes

Every Thanksgiving we head to my wife’s family for a big dinner. I love it because I don’t have to do all the cooking and only need to come up with a side dish. So after getting an Instant Pot not too long ago, I figured why not try the mashed potatoes in the Instant pot? So off to work I went.

I used five pounds of potatoes for this Thanksgiving feast but you can cut the recipe in half. Also, for Thanksgiving I really like to butter up my potatoes and use whole cream. You can cut the amount of butter and use milk instead. Just adjust to your tastes and/or any dietary restrictions you may have.

Instant Pot Mashed Potatoes


  • 5 lbs Russet Potatoes peeled and cubed
  • 4 tbsp butter
  • 1/2 cup heavy cream
  • 1 tsp salt
  • 1 tsp pepper
  • 3 cups water just enough to cover the potatoes


  1. Add the cubed potatoes to your instant pot, season with salt and add water to cover. I needed 3 cups. You may need more or less.

  2. Cover and cook on high pressure for 10 minutes. 

  3. After 10 minutes, quick release the instant pot. Check potatoes for doneness. A fork should easily be inserted into the potatoes.

  4. Drain the potatoes and save about 1/4 cup of the potatoes water

  5. Add cream, butter, potato water, and salt and pepper. Mash all ingredients with a potato masher.

  6. Adjust salt to taste and enjoy. If not eating right away you may need to add some milk to keep the potatoes from getting dry.

That is all there is to it. The Instant Pot made quick work of these mashed potatoes. Once I finished mashing I replaced the lid and off we went to grandma’s house. Once there I put the pot on heat and they did not need any milk added because the potatoes were still moist. I really love my instant pot and will be coming up with many more recipes using it soon.
