Instant Pot mashed potatoes come out creamy, fluffy and so easy to make. Born and raised in Ukraine, my grandma always made the most simple healthy mashed potatoes with butter and milk, and I do the same.

The Instant Pot has turned my cooking style upside down; you don’t have to cut potatoes super small, drain water or heat up milk.

It’s made in one pot, just like Instant Pot potato salad and Instant Pot potato soup.

Ingredients for Instapot Mashed Potatoes

  • Potatoes: Starchy russet or buttery Yukon gold potatoes work best for both mashed potatoes in the Instant Pot.
  • Water: Used for cooking potatoes in the pressure cooker.

The starchy, salty water from the Instant Pot is used after cooking to mash your potatoes! This means no draining, no cream cheese or sour cream is needed to create light and creamy mashed potatoes.

  • Whole milk: Will produce the creamiest mashed potatoes results-without using sour cream or cream cheese.
  • Butter: Adds that buttery mashed potato taste, use unsalted or salted and adjust accordingly when adding additional salt.
  • Garlic powder: For savory instapot mashed potatoes.
  • Salt and pepper: To season and taste.

What Are the Best Potatoes for Mashed Potatoes?

  • Starchy potatoes like russet or yukon gold make the best mashed potatoes.
  • However, I can’t say that you cannot use red potatoes. Yes, they are more waxy but if you buy quality potatoes (hint: organic or local) then you should end up with delicious mashed potatoes.

How to Make Mashed Potatoes in the Instant Pot

  • Add potatoes, water and salt to any size Instant Pot: Water doesn’t have to cover potatoes and adding salt before cooking helps to flavor the potatoes.

To peel or not to peel potatoes? Depends on your personal preference and mood. Sometimes I feel like skin and chunks in my mashed potatoes. And sometimes I want the creamiest mash ever.

  • Cook on high pressure for 10 minutes: Instant Pot Duo comes with low and high pressure, so pay attention. Lux model cooks only on high pressure, so just press Manual.
  • Quick Release the pressure by turning valve to Venting. No need to drain water as most of it should be absorbed by potatoes. But you can, if you wish.
  • Season and mash: Add butter, milk, garlic powder, salt and pepper and mash with a potato masher until creamy and fluffy.

Do not use blender or food processor to mash potatoes. They will turn out sticky like glue!

Optional Add-In’s and Variations

  • Doubling: Double the recipe ingredients (except water) in 6 or 8 quart Instant Pot and use same cooking time.
  • Milk substitutes: You can replace milk with buttermilk or plain yogurt. Both have more tang, especially yogurt. Unsweetened non dairy milk could be used (resulting end taste will be different).
  • Butter substitute: You can use olive oil or vegan butter to keep this recipe non dairy.
  • Add grated fresh garlic to taste. A clove should do it. I add garlic powder only for a bit of a kick.
  • Sour cream/cream cheese: Add a small amount for loaded mashed potatoes, and might as well add freshly grated cheese and bacon bits at this point!
  • Chives: As a garnish to add a fresh onion taste!
  • Fresh herbs: Finely chopped parsley, sage, thyme or rosemary add a special touch for a holiday dinner. 

Tips for Best Results

  • Mashing: Do not use blender or food processor to mash potatoes. They will turn out sticky like glue. I have not tried mixer either. I love my Ikea masher – super long handle!
  • Prevent lumpy potatoes: Mash right after cooking.
  • Watch sodium: If using salted butter, add less salt.
  • If you opt to drain your potatoes: Reserve cooking water to add back in during mashing. 
  • Salt potatoes during cooking: This helps cook the potatoes starch which results in more flavorful and creamy potatoes! 

FAQs

Can you keep mashed potatoes warm in the Instant Pot?

Yes and this is a great option for making them ahead especially during holiday cooking. I recommend stirring every so often and adding a splash of milk to prevent burning and sticking.

Can I make Instant Pot mashed sweet potatoes with this method?

I don’t see why not! You may also love this stovetop healthy mashed sweet potatoes.

What should I use to mash my pressure cooker potatoes?

I love my Ikea masher as it has a super long handle! Any potato masher will work though. If you are okay with more ‘lumps’ you could even use a wooden spoon.

Can I leave skins on for smashed potatoes in Instant Pot?

Yes! It is your preference to leave on the skins or to peel your potatoes. Texture wise, russet potato are not quite as appetizing as thinner skinned Yukon gold potatoes. Your preference, though!

Why are my instant pot mashed potatoes ‘gluey’?

Potatoes release starch when they are mashed- if you have ‘over-mashed’ them by using a mixer, blender or food processor the end result will be ‘gluey’ potatoes. I recommend using a potato masher.

How to Serve Instapot Mashed Potatoes?

There are a million ways to serve your instapot mashed potatoes. They go just about with any protein, especially meat dishes with juice or sauce.

Instant Pot mashed potatoes are super convenient for Holidays because they free up room on the stove. You can keep potatoes warm in your pressure cooker, right after cooking, until everyone is ready to sit down for a meal.

How to Store and Reheat

Storing: Refrigerate for up to 3 days.

Reheating: You should try my favorite way to reheat mashed potatoes – on a skillet with oil or butter. They get a bit of an irresistible crust. Or warm up on the stove on low with a splash of milk.

Freezing: Unlike potato cubes, mashed potatoes freeze well because they are mashed with dairy. Freeze in portions with future use in mind in an airtight container container for up to 3 months. Thaw on a counter for 4-5 hours or in the fridge overnight.

Make ahead by refrigerating peeled and cubed potatoes in a bowl covered with cold water for up to 2 days. Cook as per recipe.
