Instant Pot Mashed Potatoes are rich and creamy and so easy to make! Making mashed potatoes has never been quicker or tasted better than these Instant Pot mashed potatoes ready in 20 minutes!
I am completely obsessed with how creamy and delicious these mashed potatoes turned out in my instant pot. I have been wanting to try mashed potatoes in my pressure cooker for a while now. Because, mashed potatoes are obviously one of the most delicious side dishes on the planet, but, I don’t always feel like cooking them on a weeknight when we are busy. Now, I can have mashed potatoes ready in about 20 minutes and everyone absolutely loved them!
Instant Pot Mashed Potatoes:
Making mashed potatoes in the instant pot starts out just a simple and easy as if you were making mashed potatoes on the stove like my reader favorite Cream Cheese Mashed Potatoes.
You’ll start out with three pounds of potatoes. This is about 6 medium potatoes total. Go ahead and peel them. I haven’t tried this recipe leaving the skin on the potatoes because we prefer ours without skin.
Next, simply slice the potatoes into large rounds. For me, this came out to about 4-5 round slices per potato. There is no reason to spend time cutting them into cubes. You’ll then cover them completely in water which will be about 4-5 cups depending on what size of instant pot you’re using. The picture below shows the potato rounds in my 8 quart instant pot.
After the potatoes are covered in the water you will add 1/2 teaspoon of salt. This is just enough salt to flavor the potatoes while they cook without being overwhelming.
Then, that’s it for now! Go ahead and place the lid on your instant pot. Set the valve to sealed and cook on manual for 8 minutes. Keep in mind that it will take about 8-10 minutes for the pot to come to pressure.
Once the timer goes off you can quick release the pressure from your pot. You will need to drain the potatoes and then return them to the instant pot with the power off.
Then, simply add in the remaining salt, pepper, garlic powder, butter, milk, and sour cream. The garlic powder is, of course, optional, but, we really love that extra bit of flavor in our mashed potatoes!
You can mash these up with a standard potato masher if you wish. Or, you can mash then whip them with a hand-held mixer which is what I love to do!
After your potatoes are mashed you are set to go and eat! Make sure to taste and double check the seasoning. I have listed the amounts to our preference, but, you may prefer to add more. Always season to your own taste.
Enjoy!

These were spot on delicious! I only deviated to add more salt and some minced garlic. I’ll be adding this one to my recipe box.
Can the recipe be doubled?
You can make this with any volume. Just make sure you have water to just about cover the potatoes. Don’t go past the max of your instant pot. I made them this way and it is much better than the steaming method which I’ve also tried. I added 3 garlic cloves to the instant pot for the 3 lbs of potatoes. At the end I used sour cream instead of butter. They were great. This is a keeper
Still an 8 minute cook time if you double or triple the recipe?
Very good and simple. I need a recipe that would free up my stove and I had everything on hand for these so this is the recipe I picked. Very happy overall! My mom who is very critical of most things, picky eater, loved them even!! Huge win!
This recipe was delicious! Super quick, easy and tasty. I ended up using chicken broth instead of water and added a couple garlic cloves to pressure cook with the potatoes. Most definitely my new go to recipe for mashed potatoes!
While hubby drained the potatoes, I grabbed the sour cream from the fridge only to find my kids had made onion dip with the sour cream and lipton onion soup mix.. hesitated for half a second, tossed in a quarter cup and left the rest of the salt out. I’m pretty sure I’ll never use plain sour cream again 🙂
Thanks for the recipe!
I’ve said it before and I’ll say it again. This is the best mashed potatoes recipe on the internet. Everyone was begging for seconds….Thanks again.
They were perfect! I subbed heavy milk for the sour cream. I’ll make these again. Thanks for sharing.
Made these for Thanksgiving using 5 pounds of potatoes and 9 minutes. Except for needing more salt they were excellent. I just fork mashed them and they were lumpy but so yummy! Thanks for the recipe.
I’ve never made mashed potatoes in the instant pot, life changing. I live in Tahoe, so added 1/4 cup more milk, between an 1/8 to 1/4 cup more sour cream, and more salt and pepper.
Thank you for a great recipe! I hope you had a peace filled Thanksgiving.
We love these potatoes. Someone said the gravy ruins the potatoes. They are excellent by themselves. I like not having to watch the pot on the stovetop. Turn it on and forget It- well sort of. And they are all cooked, no hard pieces.
