Easy Instant Pot recipe mashed potatoes

For Valentine’s Day, I wanted to make an easy dinner but still something “nice.” Prep ahead is my motto in general, so I dipped strawberries in chocolate in the morning. In the afternoon, I prepped my molten chocolate cakes and popped them in the fridge.

Since we live in the midwest, I went for a simple steak and potatoes dinner. As much as I adore scalloped potatoes, I decided to go with mashed instead. To keep with my easy dinner idea, I decided to do Instant Pot mashed potatoes.

Why didn’t I do this before?

The potatoes cooked so quickly, and I can hold them in the Instant Pot until it’s time to do the last few minutes of prep before dinner. There’s nothing worse than cold mashed potatoes, and this method meant I didn’t have to perfect my timing so dinner all arrived on the table at once.

In fact, my son loved these Instant Pot mashed potatoes so much that he begged me to make another batch today. He’s been home sick all week so hasn’t eaten much.

Poor kid still hasn’t tried the steak. He may or may not have had half the latest batch because they’re that good.

Want to fancy these up even more? Add a clove of garlic to the water in the bottom of the Instant pot and put that through the ricer, too, once it cooks. Garlic mashed potatoes? Even better!

Aside from the Instant Pot, you don’t need much in the way of equipment. As much as I cook, I tend to only have gadgets that truly provide value. Garlic peeler? Nope. Corn butterer? Uh uh. Potato ricer? Absolutely.

The potato ricer is my secret to fluffy mashed potatoes with no lumps every time. This is one of the few single use tools I own because it does such a good job.

If you love mashed potatoes, get one, whether you plan to make Instant Pot mashed potatoes or a traditional version. Me? I love this Instant Pot version – and so does my family.

Needless to say, you won’t see me standing over a stove boiling potatoes again.

How to Make Instant Pot Mashed Potatoes

Wash potatoes and peel them. If you use large russet potatoes, cut them in half lengthwise then in thirds again horizontally to make good size chunks.

Place your trivet in the Instant Pot and add potato chunks atop it as you cut them. Once you cut them all, add a cup of water to the bottom of your Instant Pot.

Close the top and ensure the vent is set to seal. Set to cook for nine minutes. Once complete, do a quick release being careful to avoid the steam.

If you prep these in advance, feel free to leave the in the warm function until you want to finish them.

Use a potato ricer to “chop” them into a bowl. Halfway through the process, add butter to the bowl so the hot potatoes cover it and allow it to melt.

Once you rice all potatoes, use a spatula to stir and ensure the butter melted. Add milk and salt and stir until creamy and distributed. Serve immediately.
