Old Fashioned Mashed Potatoes Made Easy!

Everyone remembers the old-fashioned mashed potatoes that used to grace dinner tables. Thick and luscious mashed potatoes, creamy with butter and milk (or CREAM!) and seasoned to perfection, they’re the best. Make them again but faster with my Instant Pot Mashed Potatoes recipe. You’ll love them!

Why make Instant Pot Mashed Potatoes?

Sometimes you run out of room on the stove. Or sometimes you need to make them and take them somewhere. And sometimes it’s too darn hot to heat up the stove. In all of those cases, it makes sense to make Instant Pot Mashed Potatoes!

One of the NICE things about cooking in the Instant Pot? No boilovers, and no stirring down boilovers. Things JUST cook in the IP on pressure cooking without stirring. I like that!

I love making Mashed Potatoes in the Instant Pot is that when I’m making a feast I just don’t have space on the stovetop for all the things I need to do. When I use a pressure cooker, I can make the potatoes ahead of time, and leave them in the pot even once it’s off and they’ll stay toasty warm for a bare minimum of 30 minutes.

OR I can turn the pot to Slow Cooker Low and keep them warm until I need them on the table. Using a pressure cooker is just a game-changer in so many ways!

If you really want to kick up your feast try these Popeyes Mashed Potatoes!

FAQs About Easy Mashed Potatoes

Do I need water for the instant pot to cook potatoes?

Yes, you need to cover the potatoes with water before cooking.

Can I mash these potatoes IN the Instant Pot?

You can in the Inner Pot yes. I would move the inner pot to a heat-proof pad and mash there, you don’t want to damage the interior of the pot while mashing.

Can I leave the skin on my mashed potatoes?

Absolutely yes! It saves time in prepping them. We call them rustic mashed potatoes when they have the skins on.

Do I need a potato masher to make mashed potatoes?

You need something to mash the potatoes. You can use a potato ricer OR a food mill if you have one of those instead of a potato masher.

What are the best potatoes for mashing?

I think it’s a personal preference. We like Yukon Golds. Some people like reds. The best potato for mashing is the one you have in your kitchen!

How to make Thanksgiving Day Easier on the Range

  • Just making these mashed potatoes on the range gives you more room to work and less stuff to worry about.
  • I also make all the pies ahead of time I think they taste better the next day
  • Make the stuffing ahead of time too but never stuff the bird with it UNTIL you’re ready to cook it
  • And I’ve just fallen in love with my Air Fryer so I might just be doing Air Fryer Turkey Breast, then my WHOLE oven is open for whatever I want to bake
