Instant Pot Classic Mashed Potatoes

How to make mashed potatoes in your Instant Pot. Perfect side dish that can be made in your 3 quart, 6 quart or 8 quart pressure cooker.

Mashed potatoes in the Instant Pot or pressure cooker that I dont make them any other way. It just takes 10 minutes once it comes to pressure. Mashed potatoes are the perfect side dish for Sunday dinner or any of the holidays. Everyone like their potatoes a bit different but I am a traditionalist. My mom always made them with milk and butter. Unless she made her cheesy potatoes. I will have to make those for you guys soon.

Instant Pot Steamer Basket

Unlike making mashed potatoes on the stove I dont like my potatoes to sit in water. I use my steamer basket to keep the potatoes above the water line. If you dont have a steamer basket you are missing out I use it all the time for eggs and vegetables, especially broccoli. I have the 3 quart steamer basket and use it both in my 3 quart and 6 quart. Want a bigger basket? Heres a 6 quart steamer basket.

No more having to pour scalding hot water out of a pot. Just use a pot holder and lift your steamer out of the Instant Pot by the silicone handle.

Have a larger family? You can easily double this recipe in your 6 or 8 quart Instant Pot. Just add more milk and butter. For a creamier potato add a 1/4 of a cup of sour cream.

Mashed or Whipped?

Do you like your potatoes mashed or whipped? It always seems to be the question. In my family we like them mashed with a chunk of potato here or there. We always use a potato masher. If you like them whipped did you know you can just put them in your mixer for a perfect whip. Have an immersion stick blender? That works too.
