The perfect mashed potatoes for holidays—or any day!

Rich, Parmesan-topped, and peppered with fresh herbs, these luscious, creamy Instant Pot mashed potatoes are the stuff of legends.

What makes them such a favorite? Behold!

Keep Your Oven Free for Other Dishes. While I’m a huge fan of Cheesy Scalloped Potatoes and Oven Roasted Potatoes, sometimes your oven just isn’t an option (like when you’ve already got a Roast Turkey in it).
The Instant Pot Makes Them Easy. Now that I’ve discovered the beauty of cooking potatoes in the Instant Pot, I actually prefer the Instant Pot version. The prep is far more simple, the potatoes cook more quickly, and the resulting texture is superior.
Versatile Serving Options. Just like my classic Mashed Potatoes Recipe, these Instant Pot mashed potatoes can pair with any of your favorite proteins, from Honey Garlic Pork Chops to Stuffed Chicken Breast to Air Fryer Salmon.

Key Ingredients

You’ll find the full list of ingredients in the recipe card below, but here are some notes to keep in mind.

Yukon Gold Potatoes. There is a hot debate over which potato makes the best mashed potatoes. Starchy russets are the most common choice, but personally I prefer the slightly waxier Yukon golds in my mashed potatoes (as well as in my soups like Instant Pot Potato Soup). They are a little more dense, but their naturally buttery flavor and creamier texture more than makes up for it. Save your russets for Hasselback Potatoes and Air Fryer French Fries.
Herbs.A handful of fresh chives brings them to life, and fresh thyme gives them a savory taste. (Herbs are also key for Crockpot Scalloped Potatoes.)
Greek Yogurt.My swap for sour cream, cream cheese, or milk in mashed potatoes that adds creaminess (and a boost of protein) with less saturated fat and cholesterol. Its thickness and body make the mashed potatoes taste decadent, and the light tang gives the mashed potatoes a richer flavor.
Parmesan. I adore the salty sharpness that the final sprinkle of Parm on top of the mashed potatoes adds. I have a suggested amount, but feel free to be more liberal if you like.

Substitution Tip

Don’t enjoy Greek yogurt (or yogurt, in general)? Don’t worry, the potatoes do not taste like yogurt. If you’re still leery, you can swap the Greek yogurt for sour cream or cream cheese. Add gradually and adjust the amount to suit your preference to taste and consistency. Note the nutritional information will change if you make this adjustment.

How to Make Mashed Potatoes in an Instant Pot

Cut the Potatoes. This recipe was written for potato chunks that are 1 inch in size. It’s important that your potatoes are all cut this size so that they cook as intended. (For the smoothest texture, you should peel your potatoes for Instant Pot mashed potatoes, but if you want flecks of texture, you can leave the peels on.)

Pressure Cook the Potatoes. Pressure cook for 8 minutes on HIGH pressure to steam potatoes in the Instant Pot. Release the pressure.

Drain the Pot. Return the cooked potatoes to it.

Add the Remaining Ingredients. We’re almost there!

Mash the Potatoes. Don’t overwork them! The main reason mashed potatoes turn sticky and glue-like is from being overworked. As soon as you reach your desired consistency, stop mixing. ENJOY!

2 ½ teaspoons kosher salt divided
2 ½ pounds Yukon gold potatoes peeled and cut into 1-inch chunks
1 cup Greek yogurt at room temperature
2 tablespoons unsalted butter at room temperature
½ teaspoon ground black pepper
3 tablespoons fresh chives finely chopped
½ tablespoon fresh thyme chopped
¼ cup Parmesan cheese freshly grated (plus additional to taste)

Let your tap run until the water is very warm. Add 3/4 cup to the bottom of an Instant Pot or electric pressure cooker. Stir in 2 teaspoons kosher salt until it dissolves.
Insert the steamer basket and place the potatoes in the basket. Cover and cook on high pressure for 8 minutes. Quick release the pressure valve.
Drain the potatoes and remove the steamer basket and any excess liquid from the Instant Pot. Immediately place the potatoes back in the Instant Pot.
Add the Greek yogurt, butter, pepper, chives, thyme, and remaining 1/2 teaspoon salt.
With an electric hand mixer, beat the potatoes on medium speed until the ingredients are combined and your desired consistency is reached, being careful not to overmix. (You can also use a potato masher or the back of a wooden spoon). Taste and adjust seasoning as desired.
Transfer to a serving bowl and sprinkle with Parmesan. Serve warm.
TIP: If the potatoes are thicker than you would like at any point, stir in milk 1 tablespoon at a time until your desired consistency is reached.
TO KEEP WARM: To keep the potatoes warm before serving, place them in a heatproof bowl set over a pan of simmering water. Cover the top of the bowl with plastic wrap and stir the potatoes occasionally to ensure that they heat evenly.
TO STORE: Refrigerate leftovers in an airtight storage container for 3 to 4 days.
TO REHEAT: Reheat potatoes gently in the microwave or on the stove with a splash of milk to keep them from drying out.
TO FREEZE: I do not recommend freezing this mashed potato recipe since the texture of the potatoes can become mealy once thawed.
TO MAKE AHEAD: For best results, make the recipe up to 1 day in advance. Cover tightly with plastic wrap, reheat gently in a bowl set over simmering water, thinning with a bit of milk as needed and stirring every 5 to 10 minutes. Sprinkle with Parmesan just before serving.
TO MAKE ON THE STOVETOP: Peel and cut potatoes into 1 1/2-inch-thick round slices. Place in a medium saucepan and cover with cold water so that you have at least 1 inch above the potatoes. Stir in 2 teaspoons salt. Bring to a simmer to a low simmer and keep at a low simmer the whole time the potatoes cook, adjusting the heat as needed. At the 18-minute mark, start testing the potatoes for doneness. As soon as a paring knife slides into the middle of one of the potato slices easily, drain immediately. Proceed with the recipe as directed above.
