Fluffy Instant Pot Mashed Potatoes

Fluffy Instant Pot Mashed Potatoes are creamy, with just the right amount of butter and fluffiness.  This is the best and only recipe you will ever need for mashed potatoes!

Mashed Potatoes in the Instant Pot

Fluffy Instant Pot Mashed Potatoes are my latest obsession. Making the mashed potatoes in the instant pot allows me to load the pot and walk away until they’re ready. No need to watch the pot from boiling over, or checking the potatoes 15 times if they’re done. Just load them into the Instant Pot, set the timer for 11 minutes and when it beeps, you know for sure that they’re perfect!

The proportions of milk and butter to potatoes will give you the creamiest mashed potatoes, while whipping them with the mixer makes them light and fluffy!

There are two ways to make Instant Pot Mashed Potatoes and this is one of them. The other one is steaming the potatoes with one cup of water and then using that water to mash in with the potatoes. I’m not much of  fan of that kind, because the potatoes come out more “watery” and less creamy, after all, you are adding water instead of milk tothe potatoes.

So while this method is not faster than using a regular pot, it does allow you to walk away from the pot and come back when it “beeps” letting you know that the potatoes are done.

Tips for Fluffy Instant Pot Mashed Potatoes:

  • Cutting the potatoes to the same size ensures even cooking. If your pieces are smaller than 2 inches, cooking time will decrease and you might need to cook them only for 10 minutes.
  • If you want more luscious potatoes replace some of the milk with butter. The more butter the creamier the potatoes will be.
  • You can mash the potatoes using a potato masher or potato ricer instead of a mixer if you wish.
  • You can add 1 tsp of black ground pepper, or 1 tsp of garlic powder at the same time you add the milk to flavor the potatoes. Or mix in 3-4 Tbsp of chopped chives or parsley after whipping the potatoes.

Ingredients

Ingredients for Instant Pot Mashed Potatoes

  • 5 lb russet potatoes peeled (you will be left with about 4 lbs of peeled potatoes), about 14-15 medium sized potatoes
  • 1.5 cups whole milk hot
  • 4 oz butter 1/2 cup, unsalted, room temperature or melted
  • 2 Tbsp salt
  • 6 cups water

Also for garnish:

  • 2 Tbsp parsley or chives, chopped

Instructions

How to make Fluffy Instant Pot Mashed Potatoes

  1. Peel 5 lbs potatoes (I love using this vegetable peeler) and rinse them under running water.

  2. Cut the potatoes in two or three pieces horizontally, about 2 inches in size, making sure that all pieces are about the same size.
  3. Place the potatoes into the Instant Pot insert and cover with about 6 cups of warm tap water. Add 2 Tbsp of salt. Stir. Cover with the lid, rotate it to close and turn the steam release valve to “sealing”.

  4. Next, press the button “Pressure Cook” or Manual and set the timer to 12 minutes. When the timer gets to 0 and beeps, press “cancel” and turn the vent to “venting” for quick pressure release and wait until the float valve goes down. You can throw a small towel on top of the vent to prevent the splatter.
  5. When the pressure has gone down, open the lid and check the potatoes for doneness with a knife, the knife should go into the potato with no resistance. Drain the potatoes.
  6. Using a handheld mixer roughly break down the potatoes. Now, add 4 oz of unsalted butter and half the hot milk mixture. Whip for about one minute or until the potatoes are well combined with the liquid and no lumps appear. Continue adding the hot milk and whipping until the potatoes are desired consistency. You might not add all the liquid if you like the potatoes on the firmer side.

  7. Cover the pot and keep the potatoes warm until ready to serve. Serve the potatoes with your choice of meat or vegetables.
