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.

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.
