Whether you’re making mashed potatoes for a weeknight dinner or a big Thanksgiving spread, this is my favorite method for a perfect bowl of spuds.

What Kind of Potatoes to Use
Russets make for great mashed potatoes because they are starchy, but you can also use Yukon gold potatoes —the potatoes will look slightly more yellow once they’re cooked and have a smoother, denser texture.
How to Prep Potatoes for Cooking in the Instant Pot
To ensure that the potatoes cook evenly, I peel and cut them into 1-inch slices. Cut this way, I’ve found that they always take exactly four minutes to cook under pressure, and they always steam perfectly. (Heads up that the pot will take 15 minutes or so to heat up before the actual cooking begins, but the total cook time is still less than 20 minutes from start to finish.)
Add-Ins for Mashed Potatoes
I’ve included a few cloves of garlic in my mashed potatoes — they soften up and you can mash them right in. Four cloves might sound like a lot, but potatoes are such a blank slate, so this gives the whole dish a nice garlicky flavor. You can skip it if you want, though. You can definitely tweak the amounts of milk, butter, and salt to make these mashed potatoes as creamy as you like. The proportions I use here make the potatoes taste buttery, but they’re not overly rich—my favorite. Feel free to fold in your favorite cheese, sour cream, or fresh herbs after mashing.
Make-Ahead and Reheating Instructions for Mashed Potatoes
You can make mashed potatoes in the Instant Pot and leave the pot on the “Warm” setting while you go about prepping the other dishes. You can also make mashed potatoes ahead of time. You can even make ahead and freeze mashed potatoes. Just don’t skimp on the butter or cream because the fat helps the potatoes reheat well. We like to reheat mashed potatoes by putting them in the microwave (covered) for a couple of minutes, and then stirring them well before serving. You can also put them in a slow cooker for a couple hours on low, or reheat in the oven, covered, or on the stovetop. Just stir occasionally, and add more butter and seasoning if needed to serve.
Leftover mashed potatoes will keep for 3 to 4 days, covered and refrigerated.
What to Serve With Mashed Potatoes
Serve your mashed potatoes with a holiday turkey or roast, or a weeknight dinner of Salisbury steak or meatloaf. I bet you will up making them more often with this easy method!

Secure the lid on your pressure cooker and make sure the pressure release valve is set to its “sealing” position. Select the “Steam” or “Manual” setting and set the cooking time to 4 minutes at high pressure. (The pot will take about 15 minutes to come up to pressure and then the actual cooking will begin). When the cooking program ends, perform a quick release by moving the pressure release valve to its “venting” position.
