Instant Pot Mashed Potatoes – Love and Lemons

These Instant Pot mashed potatoes are rich, buttery, smooth, and creamy. Made with just 5 ingredients, they’re such an easy, delicious side dish.

When I made these Instant Pot mashed potatoes for the first time, my goal was to earn Jack’s stamp of approval. He’s a devout mashed potato lover, so if these Instant pot mashed potatoes weren’t fluffy or flavorful enough, I knew I could count on him to let me know.

After a few tastes and a tweak or two, he began happily scooping himself a bowl. “They’re great!” he said. And I had to agree. I don’t usually consider myself much of a mashed potato person, but at that moment, Jack wasn’t the only one loading up a bowl. I was too! The Instant Pot mashed potatoes were smooth, creamy, and full of rich, buttery flavor. After I finished my bowl, I started stealing tastes straight from the pot!

Instant Pot Mashed Potatoes Recipe Ingredients

Here’s what you’ll need to make this Instant Pot mashed potatoes recipe:

• Potatoes, of course! I recommend using Yukon Gold potatoes, or a similar variety of yellow potatoes, for this recipe. They give the mash a pretty golden color, a rich buttery flavor, and a delicious creamy texture.
• Water – You’ll use it to cook the potatoes in the Instant Pot. Then, in lieu of sour cream or cream cheese, you’ll mix some of that starchy, salty cooking water into the mashed potatoes to create their light, smooth texture.
• Garlic – It adds a subtle savory bite.
• Extra-virgin olive oil and butter – They make the potatoes flavorful, buttery, and rich. Find a vegan option in the recipe below!
• Chives – For a fresh, oniony garnish.
• And sea salt and freshly ground black pepper – To make all the flavors pop!

How to Make Mashed Potatoes in the Instant Pot

This recipe is so easy to make! Here’s how it goes:

First, prep the potatoes. Scrub them, peel them, and cut them into large chunks. Aim to cut the potatoes to roughly the same size so that they cook evenly in the Instant Pot.

Pile the chopped potatoes into the Instant Pot…

…pour in water to cover, and stir in 2 teaspoons of salt.

Then, cook! Secure the lid on the Instant Pot and set the steam release handle or switch to the sealing position. Pressure cook on High Pressure for 12 minutes. Quick release the pressure and remove the lid.

Important: Make sure to reserve 3/4 cup of the cooking water before you drain the potatoes!

Drain the potatoes…

…return them to the pot, and mash! Add the garlic, olive oil, butter, and remaining salt and continue mashing to fully incorporate them with the potatoes.

Finally, add the cooking water. Fold in 1/4 cup at a time until the mash is smooth and creamy. Season to taste with salt and pepper, and serve!

Instant Pot Mashed Potatoes Serving Suggestions

These Instant Pot mashed potatoes would be a great side dish for any fall or winter meal, but I think they’re especially perfect for Thanksgiving. Cooking them in the Instant Pot clears up some space on the stove for your sautéed Brussels sprouts, cranberry sauce, or whatever other Thanksgiving side dishes you might be making. And if you can’t get to the potatoes right away, they can hang out on the Instant Pot’s Keep Warm setting until you can. How handy is that?!

When you’re ready to serve, top them off with fresh chives, black pepper, and a big pat of butter (or vegan butter). They’d also be fantastic with a ladle of my mushroom gravy.

If you have leftovers, store them in the fridge for up to 3 days. They reheat surprisingly well in the microwave. Enjoy!
