Mashed Potatoes Instant Pot Method

I have been looking forward to sharing this method for making mashed potatoes for awhile now. My family lives off of potatoes and mashed potatoes are one of our very favorite side dishes. Too often, our busy schedules get in the way and I find myself making a sub-standard side dish for dinner instead of the mashed potatoes we are all craving.

Then I discovered the instant pot. There are many recipes that I find to be too time consuming with the instant pot but let me tell you, it is MADE for mashed potatoes.

In under 20 minutes, you can have creamy, rich, buttery mashed potatoes on the dinner table and my friends, there is just nothing better than that.

With this recipe, you just toss all the ingredients into the pot, set it, and let it do the work for you! Sure, you still have to actually mash the potatoes but let’s face it – that’s the fun part! Ready in mere minutes, you can have put your focus on other dishes and let your instant pot get to work.

What You’ll Need

All the classic ingredients for your favorite comfort food! As always, you can find the full printable recipe with complete instructions in the recipe card at the end of this post. Let’s take a look at what you’ll need:

  • russet potatoes or Yukon Gold – Russet potatoes produce a lighter, softer and fluffier mashed potato than other potatoes. You can also use Yukon or red potatoes, which will produce denser, creamy mashed potatoes.
  • low sodium chicken stock or broth – I like to use half broth and half water but all water can certainly be used in this recipe.
  • kosher salt – Kosher salt enhances the flavor profile of foods rather than making them taste salty. You may use sea or table salt if that is what you have on hand. If you do, reduce salt measurement to 1 teaspoon, divided.
  • unsalted butter – it’s simply not mashed potatoes without butter! Adds richness to the dish and gives these potatoes that buttery flavor. If you only have salted butter, reduce the salt by a bit.
  • half and half or whole milk – this adds creaminess and richness to the mashed potatoes.
  • sour cream – Sour cream brings an incredible creaminess to these mashed potatoes and adds a pleasant tang. Cream cheese is a great substitute if needed.
  • ground black pepper – this recipe uses black pepper as a flavor enhancer.

Substitute heavy cream for even richer mashed potatoes or swap in whole milk or 2% milk for a less decadent version.

  5. Cook on ‘MANUAL HIGH’ for 12 minutes.

  7. Drain the water from the Instant Pot.
  8. Use a potato masher to mash the potatoes until they are smooth.
  9. In a small saucepan or in the microwave, heat unsalted butter and half and half (or whole milk if using) until the butter melts.
  10. Pour the mixture over the potatoes and stir to combine.
  11. Add sour cream, one teaspoon kosher salt and freshly ground black pepper. Stir until the ingredients are blended.

  • Add additional half and half or whole milk to your mashed potatoes to thin them out if needed.
