HOW TO MAKE MASHED POTATOES IN AN INSTANT POT

Making mashed potatoes in the instant pot is so easy! First, peeled quartered potatoes are placed in your instant pot and covered with water. The potatoes are pressure cooked on high pressure for 12 minutes with a quick release. The potatoes are then drained and mashed with butter, milk, salt, and sour cream. See below for a detailed ingredients list and instructions.

WHAT KIND OF POTATOES SHOULD I USE FOR MASHED POTATOES?

The best kind of potatoes to use for this classic instant pot mashed potatoes recipe is russet potatoes. Russet potatoes are high in starch and give the potatoes a creamy, fluffy texture. Other popular choices are red potatoes or Yukon gold potatoes, but I prefer russet!

CAN I MAKE MY INSTANT POT MASHED POTATOES WITH THE SKIN?

Yes! If you would like to prepare your mashed potatoes in the instant pot with the skin on, simply skip the peeling of the potatoes and prepare the recipe as directed.

HOW TO REHEAT MASHED POTATOES

Mashed potatoes can be reheated in a covered casserole dish in the oven at 350 degrees F, or in the microwave, stirring occasionally, until heated through.
