Instant Pot Mashed Potatoes

 

LIFE-CHANGING INSTANT POT MASHED POTATOES

yield: 6 SERVINGS

 

prep time: 32MINUTES MINS

cook time: 8MINUTES MINS

total time: 40MINUTES MINS

INGREDIENTS

• 4 pounds potatoes, peeled and cut into 1-inch cubes (see note about type of potatoes)
• 2 teaspoons coarse, kosher salt
• 1 cup milk, preferably not skim
• 4 tablespoons butter, cut into tablespoon-size pieces
• ½ teaspoon garlic powder
• ½ cup sour cream

INSTRUCTIONS 

• Add the potatoes and salt to the Instant Pot insert (6-quart). Add at least 1 1/2 cups water or enough to cover the potatoes (either way is fine). Don't exceed the max fill line.
• Secure the lid on the Instant Pot, making sure the valve is set to "seal" and not "vent."
• Select Manual and then dial up or down to 8 minutes. The IP will start on its own.
• While the potatoes cook, warm the milk, butter and garlic powder in a saucepan or microwave-safe container until the butter is melted and the mixture is warm.
• When the potatoes are done cooking, quick release the pressure. If liquid bubbles and spurts from the valve, cover loosely with a damp dishcloth while the pressure releases.
• Drain the potatoes in a colander over the sink, discarding the cooking liquid.
• Return the potatoes to the insert of the Instant Pot and coarsely mash.
• Add the 2/3 of the butter/milk mixture along with the sour cream, and mash until the potatoes are the desired texture, as smooth or as chunky as you like, adding more of the remaining milk/butter mixture if you want creamier, less stiff mashed potatoes (I usually add it all).
• Add salt and pepper to taste.
• Serve immediately OR return the insert to the Instant Pot, secure the lid, and select Keep Warm. The potatoes can stay on this setting for up to three hours.
• When ready to serve, give the potatoes a good stir and a drizzle of warm milk, if needed.

NOTES

Potatoes: my favorite type(s) of potatoes to use for mashing are a combination of red potatoes and Yukon gold potatoes. But you can definitely vary the type of potato used in this recipe without altering cooking time. 

Instant Pot: I buy potatoes in bulk (I do live in Idaho after all), so I always weigh out the 4 pounds (or 8 pounds if using my 8-quart Instant Pot) for this recipe, but you should be able to fit in a commonly sold 5-pound bag of potatoes into the 6-quart Instant Pot, as long as the max fill line isn't exceeded after water is added. Just increase the milk/butter/sour cream/garlic powder a smudge to account for the extra pound.
