Instant Pot Mashed Potatoes

The Easiest Way to Make Creamy and Delicious Real Mashed Potatoes

These no-fuss, peel or no-peel homemade mashed red potatoes are super easy to make and so, so good! Peel for a smooth and creamy texture or leave the skins on for a more hearty, rustic texture and some added nutrients. This is a wonderful side dish for those busy weeknights when you need something fast that the family will devour.

We eat a lot of mashed potatoes! We love having it as a side with so many meals. I must confess though, I had never made real mashed potatoes until a few months ago. Yes, I used the packets of flakes. They’re fast and easy to make and they taste good enough. I mean, at the beginning I missed the taste of the mashed potatoes I grew up on, but after so many years, I got used to it.

These Mashed Potatoes Really Are Amazing

Well, I made mashed potatoes in my Instant Pot a few months ago and oh my gosh! I feel bad I’ve been depriving my kids of this amazingness all these years. It’s one of those things that took way too much time for me to even consider making them from scratch. Until the Instant Pot that is.

Kitchen Prep Tools, Utensils & Appliances

Here is a list of the kitchen prep tools, utensils, and appliances I used to make this recipe.

Prep Tools & Utensils

These are the items I used to prep and make this recipe:

  • For cleaning the potatoes, I always use my vegetable brush to get all the dirt out of the nooks and crannies.
  • I recently got this amazing vegetable peeler. I had always heard people rave about it but didn’t realize how great it was until I tried it. It sure makes quick work of peeling potatoes.
  • My beloved aqua knives helped me quarter these potatoes with ease.
  • There is no reason why kitchen utensils can’t be both beautiful and functional. That’s why I love my measuring cup and measuring spoons so much. They are both so pretty and practical all at the same time.
  • To keep my hands protected and keep the pot from slipping as I mashed the potatoes, I used my mini mitts to grip the pot and keep it steady. They’re great because they are easy to slip on and have ridges on the palm side so that I can keep a good grip on things so I don’t have to worry about them slipping out of my hands.
  • I have just about every piece of this aqua utensil set and that includes the wire masher I used to mash these potatoes. The set is so beautiful and fits my decor perfectly. I have most of it in a cute utensil holder on the counter because they are that pretty. Not only do they look great but they are also high quality utensils.

Making Mashed Potatoes in the Instant Pot

Here are the simple steps I followed to make perfect no drain Instant Pot mashed potatoes.

Wash, Peel and Cut the Potatoes

First, make sure you wash and peel your potatoes. I usually make mine with red potatoes. I’ve made them with and without the peel depending on what mood I’m in. If you leave the peel on, make sure to wash them well.

Once washed and peeled, quarter your potatoes.

Continue Mixing Until Smooth and Creamy

  • Amy says:

    If I only want half that amount of potatoes, should I half the water amount?

  • Shirley says:

    If I needed to double the quantity to 10 lbs of potatoes, would I need to increase the cook time?

  • Chris says:

    Did you drain the potatoes or is the water absorbed/ steam?

    Thanks in advance.
