Is there any better comfort food than classic mashed potatoes? Mashed potatoes are a perfect side to serve alongside hearty meals, like roasted turkey or fried chicken. Well, we’ve been making them in our favorite gadget lately on nights when we need a quick, comforting and delicious side-dish to serve with dinner–and at this point, we’re never going back to making them the traditional way.

These Instant Pot Mashed Potatoes are creamy and flavorful, yet so simple to make. Plus, we’re sharing a few different suggestions for how to customize them to your dietary needs.

Ingredients Needed

  • Potatoes (see below for suggestions)
  • Milk
  • Butter or Ghee
  • Salt and Pepper
  • Garlic Powder
  • Parsley or Chives

Substitution Ideas

Milk: You can use dairy milk here, or you can use another milk your family typically uses such as almond milk, oat milk or rice milk. I don’t recommend using coconut milk here, as it will impart too much of a coconut flavor. You could also use chicken or vegetable broth to avoid milk altogether, like we do in this Vegan Mashed Potato recipe.

Butter or Ghee: Butter is ideal for this recipe for the flavor it gives the mashed potatoes, but ghee works equally as well for Paleo and Whole30 diets. Alternatively, for fully dairy-free you could use olive oil or avocado oil.

Herbs: Use whatever herbs you like here, we recommend topping them with chives or parsley, but rosemary or thyme would work too.

Ideal Potato to Make Instant Pot Mashed Potatoes

You’ll often see recipes calling for the more traditional Russet potato to be used, because of its high starch and low moisture content. They work really well in this recipe.

But if we had to choose, we’d always choose yellow potatoes! Yellow potatoes, sometimes labeled as Yukon Gold or creamer potatoes, have creamy flesh with a medium starch level.

A third option would be a red-skinned potato. These potatoes can be a bit waxy, and low in starch, which can make them feel a bit denser. Some people enjoy mashed potatoes with red potatoes!

Different Ways of Mashing Potatoes

Everybody has their own favorite method of making mashed potatoes, and after they are cooked in the Instant Pot, you could use your favorite. We like to just grab out the trusty masher to easily and efficiently mash the potatoes right inside the Instant Pot. However, others find these other methods to be their favorite when it comes to actually mashing the cooked potatoes:

  • using a potato ricer
  • using a food mill
  • immersion blender
  • a fork
  • mixing them with an electric mixer

Please note, if you are using an immersion blender or an electric mixer you must be careful not to overmix potatoes. It is entirely possible to work the potatoes too much, which can turn the potatoes from creamy to gluey. So if you are using an electric machine, just work the potatoes until they just come together.
