  • 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.
  • 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.

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. 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 time to 8 minutes.

Step Four

Once the cooking time is complete, use the natural-release or quick-release to unlock the lid. Use a potato masher to carefully 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.

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.
