Ingredients for Instant Pot Mashed Potatoes
- Russet Potatoes: Russet potatoes are the best type of potato for this recipe because of their classic taste and starchy texture. They are also very cost effective. If you don’t have them on hand, you can substitute Yukon gold potatoes, though they will have a slightly different consistency, or red potatoes.
- Water: A liquid is always needed when you use the instapot. I recommend using filtered cold water (I use my Berkey for things like this). If you want to add even more flavor, you can use chicken stock instead!
- Salt: Salt is key in this dish to balance and enhance the flavors!
- Cream Cheese: Cream cheese adds an extra level of creaminess to this dish. To make this dairy free and/or vegan, replace it with your favorite plant-based brand.
- Butter: What goes better with potatoes than butter? I recommend using salted regular butter.
- Sour Cream: Sour cream adds an extra level of richness to this dish. For a dairy-free option, replace with your favorite plant-based brand.
- Milk: Milk is an essential liquid to give your mashed potatoes the right texture. For a dairy-free option, use your favorite plant-based milk instead. If I have whole milk or heavy cream on hand I love to use those!
- Black pepper: optional and to taste of course

How to Make Instant Pot Mashed Potatoes
- Start off by washing and peeling your potatoes.
- Next, cut the potatoes into roughly 2-inch chunks. There’s no need to be very precise, just make sure they are around the same size so they cook evenly.
- Take the cut potatoes and place them into your 6-quart Instant Pot. Pour your cups of water (or you can use chicken broth for a richer flavor) over the potatoes and sprinkle evenly with salt.
- Put the Instant Pot lid on and seal, making sure that the pressure valve is completely closed.
- Set the Instant Pot to manual mode for 11 minutes.
- At the 11 minute mark, use the pressure release. Just be sure not to open the top of the Instant Pot until all of the pressure has released out of the top. You’ll know when it’s done when the hissing stops.
- Open the lid carefully. Do not drain the excess water from the potatoes.
- Add the remaining dairy ingredients (the sour cream, butter, cream cheese, and milk) to the cooked potatoes while they are still in the Instant Pot.
- Mix with a hand mixer or electric mixer until they are smooth and creamy. You can also use an immersion blender
- Enjoy this classic comfort food!

Frequently Asked Questions
Cut the potatoes into 2 inch chunks and place them into the Instant Pot for 11 minutes. Once you quick-release the pressure and all the pressure has released, they will be ready for the next step!
After you add the chopped potatoes, you will need to add ½ cup of water (or chicken broth) to cook them!
You can definitely use a little oil instead of butter (I’d recommend olive or avocado), but butter will be the best option to help create the rich, creaminess that you are looking for. You might also consider using a plant-based butter instead, since that will give you a result that is a little closer to butter.
The potatoes cook in the Instant Pot for 11 minutes, and then take a few additional minutes to fully vent the pressure.
You can take the potato skins off or leave them! It’s up to you! I always tend to think the skin has the good stuff in them, but for the creamy texture, I usually peel mine!
