Ingredients for Instant Pot Mashed Potatoes

Potatoes, milk, butter, garlic powder, salt and pepper.
  • Potatoes: Starchy russet or buttery Yukon gold potatoes work best.

How to Make Mashed Potatoes in Instant Pot

Here is a quick overview how to make Instant Pot mashed potatoes. You can find full recipe card down below.

Step by step process how to make mashed potatoes in Instant Pot.
  • Combine ingredients: In any size Instant Pot, add potatoes, cold water and salt. Water doesn’t have to cover the potatoes. Adding salt before cooking helps to flavor the spuds.
  • Cook the potatoes: Pressure cook potatoes on high pressure for 10 minutes Instant Pot Duo comes with low and high pressure, so pay attention. Instant Pot Lux cooks only on high pressure, so just press Manual button.
  • Release the pressure: Release the pressure right away by turning valve to Venting, Quick Release. No need to drain the 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, pepper and mash potatoes with a potato masher until creamy and fluffy.

What Are the Best Potatoes for Mashed Potatoes?

The golden standard for mashed potatoes are starchy potatoes like russet potatoes.

However, I can’t say that you cannot use red potatoes, yellow potatoes or Yukon gold potatoes. Yes, they are more waxy but, in my experience, they still yield delicious mashed potatoes in Instant Pot. It comes down to personal preference.

Tips for Best Results

  • Peel or don’t peel the potatoes: You can leave the skin on or peel it on any thin skin potatoes like red potatoes, yellow potatoes or Yukon gold potatoes. I recommend to always peel russet potatoes because their skin is quite thick.
  • Do not use blender or food processor: To mash the potatoes. They will turn out sticky like glue. I have not tried an electric hand mixer but I know it is often used.
  • To prevent lumpy potatoes: Mash right after cooking, while potatoes are still hot and the most starchy.
  • To double the recipe: Perfect for serving a crowd. Double all ingredients, except water, in 5, 6, 8 or 10 quart Instant Pot but keep same cook time.
  • Salt potatoes during cooking: Potatoes absorb salt and become more flavorful during cooking. If you salt potatoes after, there is a risk of overworking the potatoes, making them gooey.

Variations

  • Milk: You can replace milk with buttermilk or plain yogurt. Both have more tang, especially yogurt. You can also use unsweetened non-dairy milk but keep in mind that taste will be different.
  • Butter: You can use olive oil or vegan butter to make this Instant Pot mashed potatoes recipe dairy-free. Remember to use plant-based milk then as well.
  • Sour cream or cream cheese: Add a small amount for loaded mashed potatoes. And might as well add freshly grated cheese and bacon bits at this point!
  • Fresh chives: As a garnish to add fresh onion taste.
  • Fresh herbs: Finely chopped parsley, dill, sage, thyme or rosemary add a special touch for a holiday dinner.

What to Serve with Instant Pot Mashed Potatoes?

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

Making mashed potatoes in Instant Pot is 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 Instant Pot mashed potatoes leftovers 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 heat with a splash of milk.

Freezing: Unlike potato cubes, mashed potatoes freeze well because they are mashed with dairy products. Freeze the mash in portions with future use in mind, in an airtight 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.

FAQs

Do I have peel the potatoes?

It is up to you to peel your potatoes or leave the skin on when it comes to red potatoes, yellow potatoes or Yukon gold potatoes. I highly recommend to peel russet potatoes because their skin is quite thick and mashed potatoes will not turn out appetizing.

Why are my Instant Pot mashed potatoes gluey?

Some potatoes are low starch varieties, they don’t break down or absorb dairy well resulting in gluey or gummy texture once mashed. Be sure to use russet potatoes or Yukon golds, and don’t use blender or food processor to mash them.

Can I keep mashed potatoes warm in an Instant Pot?

Yes, you can keep mashed potatoes warm in Instant Pot by using Keep Warm function. Close the lid with vent on Sealing or Venting, doesn’t matter, and stir every so often and add a splash of milk to prevent burning and sticking. It is a great option for making them ahead especially during the Holidays.

Can you reheat mashed potatoes in Instant Pot?

Yes, you can reheat mashed potatoes right in your Instant Pot. To do so, press Saute, add a splash of milk or chicken broth, and cook for 4-5 minutes, stirring a few times.

    These potatoes are a picky-family favorite and are actually smooth enough and creamy enough without milk at all. We use Earth Balance Vegan Margarine and they are excellent. Thanks for changing my potato game for the better.

    1. I never used a ricer but I don’t think it will. It’s very fast movement of a blender that makes it gooey. So, I think you should be fine!

    I usually do whole potatoes on a trivet in the IP, this method was better and i won’t go back πŸ™‚ I was always too impatient to cut potatoes in equal-sized chunks but slices are straightforward and quick. Thx!
