While mashed potatoes is a traditional holiday and wintertime dish, I actually make it all year round. Potatoes are abundant and budget-friendly, and this recipe is just so easy peasy. See my other tips for how to eat clean on a budget.

Why You Need This Recipe

  • This is a one-pot healthy side dish that requires hardly any effort. The potatoes cook completely in the Instant Pot, so mashing the potatoes is super easy.
  • The potatoes absorb most of the liquid, so there’s no need to drain the potatoes after cooking. This saves time and is safer too, since you don’t have to deal with hot liquid.
  • Adapt this recipe to your dietary needs. Don’t have almond milk? You can use regular milk instead. Don’t want to use any dairy? Substitute vegan butter for the ghee or butter.
  • Easily make a double batch of this recipe for holidays or gatherings. Or, make a double batch for your family today, and then freeze the leftovers for the future. Cooked mashed potatoes keep in the freezer for up to 2 months.

Key Ingredients

White potatoes like Russet potatoes or Yukon Gold potatoes are perfect for these creamy mashed potatoes. You don’t need to bother removing the skins. The skins literally just melt into the cooked potatoes and add a little bit of nutrition and fiber.

Broth adds the liquid necessary to get the Instant Pot up to pressure. I like to use a reduced-sodium vegetable broth for this recipe.

Unsweetened almond milk helps add creaminess with no dairy.

Butter, ghee, or vegan butter adds some fat and richness to the dish.

Salt and black pepper add some more flavor.

Recipe Steps

Step One 

The first step for this Instant Pot Mashed Potatoes recipe is to gather up your potatoes. You can use white potatoes, red potatoes, or gold potatoes. You can even mix the types of potatoes you use.

You will need about two pounds, or about 8-12 medium sized potatoes. 

Step Two

Scrub the potatoes and cut them in half. Add them to the base of your 6-quart or 8-quart Instant Pot. New to using the Instant Pot electric pressure cooker? See my guide for how to use the Instant Pot Duo.

You don’t need the trivet for this recipe.

Step Three

Add one cup of water or broth. Lock on the lid and push the button for pressure cooking. Set the cook time to 8 minutes at high pressure.

Step Four

Once the cooking time is complete, let the pressure come down naturally for about 5 minutes. Then, use the quick release to get rid of any remaining pressure. Use a potato masher, whisk, hand mixer or a big spatula to mash the potatoes. Add the ghee or butter and stir until combined. Pour in the almond milk and give the potatoes one final stir.

Serve hot.

I hope your family loves this potato recipe for weeknight dinners as much as mine does!

FAQs

How long do you cook mashed potatoes in the Instant Pot?

I recommend 8 minutes for medium-sized potatoes cut in half.

What kind of potatoes can I use for mashed potatoes?

You can use whatever you like! I have made mashed potatoes with white, red, gold, and even sweet potatoes! (See my recipe for Instant Pot Mashed Sweet Potatoes).

Do I need to drain the liquid after cooking the potatoes?

I find that you don’t! The liquid gets absorbed into the potatoes to help make them mashed. The only way that you would need to drain off the cooking liquid is if you cut this recipe in half. 

Can I freeze cooked mashed potatoes?

Yes, absolutely! I usually end up freezing half of the batch for later.
