Instant Pot Mashed Potatoes
Description
This recipe employs an Instant Pot to steam quartered peeled potatoes set on a steamer rack with 1 cup of cold water beneath. Pressure cooking at high pressure for 8 minutes softens the potatoes evenly while retaining moisture. Milk is warmed separately, and room temperature unsalted butter is cut into cubes in preparation.
After cooking, the potatoes are transferred out of the pot and mashed with butter and hot milk, resulting in a creamy texture. Salt to taste is added to complete the seasoning. The use of a steamer rack prevents potatoes from becoming waterlogged, preserving their structure for ideal mashing.
The flavor and texture can be adjusted based on the type of potato used, with Russet potatoes providing fluffy results and Yukon Gold potatoes imparting a silkier finish. The potatoes can be mashed with a food mill or potato masher depending on the desired texture—creamier or chunkier. The mashed potatoes can be kept warm in the Instant Pot for about an hour, with careful stirring to reincorporate separated butter.
The recipe can be doubled without adjusting cooking time, and various milk types can be substituted for different creaminess levels. The dish is a convenient and reliable way to make mashed potatoes with minimal active cooking time and consistent results.
