But, this summer, in my very hot Texas kitchen, I fell in LOVE with using the Instant Pot to make potatoes. It all started with steaming potatoes for potato salad, then I started par-cooking potatoes before frying or roasting them, and finally, I figured out I could make perfect mashed potatoes in my Instant Pot. I loved that I could keep making my favorite potato dishes without heating up the kitchen, and get perfectly-cooked potatoes every time.

That's exactly why I love these Instant Pot mashed potatoes. You don't have to stand by the stove keeping watch over the potatoes and checking their doneness. And you can set the timer and move on to other things without worrying about overcooking. This method also produces consistently creamy, fluffy mashed potatoes that are to-die-for. They're easy enough to serve for dinner on a weeknight, but also special enough to add to your Thanksgiving spread!

Speaking of, making mashed potatoes in the Instant Pot is a great hack for when you're hosting a large dinner. It allows you to make the potatoes in advance and keep them warm until they're ready to serve, without taking up any extra space on the stove.

Which potatoes are best for making mashed potatoes?

There are a lot of varying opinions out there about which type of potatoes make the best mashed potatoes, below are our personal favorites!

  1. Yukon Gold – these potatoes are our top choice for mashing potatoes. They absorb less water than other varieties of potatoes, meaning your mashed potatoes will taste richer. They also naturally have a lovely, buttery texture that you won't find in other potatoes.
  2. Russet Potatoes – Russet potatoes are a close second to Yukon gold potatoes. They still produce a nice, fluffy mash, but have less flavor and absorb a bit more water.
  3. Red Potatoes – red potatoes are less starchy than Yukon gold and russet potatoes, meaning that the resulting mashed potatoes won't be quite as creamy and fluffy.

What's the best way to mash potatoes?

There's also a lot of debate about the best way to mash potatoes! If you want the smoothest, creamiest consistency possible, we recommend using a potato ricer. This takes a little bit more work, but will effectively get rid of all of the lumps in your mashed potatoes. Personally, I prefer a more home-style mashed potato, and use a masher with multiple holes in it like this one. This gives the result of a mostly smooth mash with just a few lumps.

You can also whip your potatoes with an electric mixer for a fluffier texture, just be sure not to overbeat! Also, never put potatoes in a food processor or blender – your result will be gluey, stuck together potatoes.

Tips For Making the Best Instant Pot Mashed Potatoes

Here are a few of our best tips for making mashed potatoes:

  1. Salt the water. Have you ever had the experience of making mashed potatoes and feeling like you can't get enough salt into them? The trick here is to salt the water first. This flavors the potatoes while they're cooking so you won't have to add much salt after the fact.
  2. Cut the potatoes evenly. We call for dicing the potatoes into 1-inch pieces, by making sure they are uniformly cut, you'll ensure that all of the potato pieces cook evenly.
  3. Quick-release the pressure on the Instant Pot. For this recipe, you want to make sure you perform a quick-release on the Instant Pot. If you let the pressure release naturally, the potatoes will overcook and absorb too much water.
  4. Get a strainer insert. This one isn't a must-have, but using a silicon strainer insert like this one makes this recipe even easier!

How to Make Mashed Potatoes in the Instant Pot

Instant Pot mashed potatoes require just a few easy steps:

  1. Dice the potatoes into 1-inch cubes.
  2. Add the potatoes to your Instant Pot and cover with 1 inch of water.
  3. Set the Instant Pot to cook for 9 minutes.
  4. When the timer goes off, release the pressure, then drain the water from the potatoes and add them back to the Instant Pot.
  5. Mash the potatoes, then stir in the butter, cream, salt, and pepper.

See? It couldn't be simpler!

Variations

We've given you a classic (but oh-so-good) mashed potato recipe here, but you can easily jazz them up with some of the ideas below:

  • For Dairy-Free Mashed Potatoes: Substitute full-fat coconut milk for the heavy cream, and ghee or your favorite dairy-free butter substitute for the butter.
  • For Roasted Garlic Mashed Potatoes: Slice a bulb of garlic in half, rub it with 1 teaspoon extra-virgin olive oil, then wrap it in foil and bake at 400 F for 30-40 minutes, until the cloves are soft. Squeeze the roasted garlic out of its papery skins, then mash and stir into the potatoes for a rich, garlicky mash.
  • For Cheater Garlic Mashed Potatoes: Add 1 teaspoon garlic powder to your mashed potatoes – this will give you great garlic flavor without the work of roasting!
  • For Loaded Mashed Potatoes: Replace the cream in the recipe with sour cream, then stir in 2-3 slices crumbled bacon, 3/4 cup shredded cheese, and 1 tablespoon of sliced chives for truly decadent potatoes.
  • For Lightened Up Mashed Potatoes: Replace the cream with a flavorful stock or bone broth – this will add a ton of flavor to your potatoes!

Do I need to increase the Instant Pot's cook time if I double the recipe?

Nope! One of the best things about the Instant Pot is that you don't have to adjust the cook time even if you are cooking more potatoes. Just note that the pot will take a bit longer to come to pressure the more you add to it.
