Ingredients

1 cup cold water
1 cup butter plus more for serving
1 cup whole milk or half-and-half
1 cup sour cream or plain Greek yogurt
Salt to taste
Black pepper to taste

US Customary - Metric

Instructions

Place the metal trivet or silicone basket inside the stainless steel cooking pot of your Instant Pot. Add 1 cup of cold water.
Peel the potatoes, then chop them into 1 to 2-inch chunks of equal size. Place the potatoes on top of the metal trivet or inside the silicone steamer basket.
Cover and switch the pressure valve to the sealing position. Cook on high pressure for 8 minutes. Note: The Instant Pot will take about 15 minutes to reach pressure before the countdown begins.
Switch the steam release valve to the venting position for a quick release. Remove the lid once the valve pops.
Drain the potatoes in a large colander and set aside. Meanwhile, remove the inner pot from the Instant Pot, wash and dry well, then transfer the potatoes back to the Instant Pot.
Gently heat the butter, milk, and sour cream in a small saucepot set over medium heat until warm. Set the Instant Pot to “warm” and add the dairy mixture to the potatoes.
Use a potato masher to mash the potatoes until the desired consistency is reached. Add additional milk or cream, as needed, and season with salt and black pepper to taste.

Notes

You may use salted or unsalted butter.
The best potatoes for mashed potatoes: starchy potatoes including russet potatoes or Yukon gold potatoes, or some combination of the two.
