Instant Pot Mashed Potatoes with Sour Cream are the most delicious mashed potatoes you will ever have. They’re light, creamy, buttery & quick to make with the help of your pressure cooker.
I love making potatoes in the Instant Pot – it makes things so much easier and frees up your stove. That’s why these Instant Pot Sweet Potatoes and Instant Pot Baked Potatoes are on constant rotation in our house.
Thanksgiving is quickly approaching and I’m already putting together menu possibilities in my head – should I serve glazed ham this year? Or stick to turkey?
We all know that come Thanksgiving, stove and oven space is always limited. That’s when the Instant Pot comes to the rescue. Just plug it in, pop it in the corner, and you can basically set these potatoes to cook and forget about them until that timer beeps.
In less than 30 minutes, you’ll have the most perfect bowl of golden, creamy, delicious mashed potatoes. Perfection.
This recipe for Instant Pot Mashed Potatoes is a variation of my Easy Mashed Potatoes with Sour Cream. I pile on the flavor starting right from the beginning by pressure cooking the potatoes in salted chicken broth.
You know how you salt your pasta water? This is kind of the same idea.
The broth will impart a flavor to the potatoes from the outset and give you that extra flavor that mashed potatoes can sometimes lack. Then, when the potatoes are cooked, they get a good dose of butter & sour cream (for a bit of tang). It’s totally worth splurging for these beauties.
🥔 What Potatoes are Best for Mashed Potatoes?
- I prefer to use Yukon Gold potatoes for my mashed potatoes. I find them buttery and delicious. However, Russet potatoes are another great variety that produces fluffy mashed potatoes.
I prefer smooth mashed potatoes, so I peel them. However, if you like your potatoes with a bit more texture, you can definitely leave on the potato skins.
🕕 Cook Time
- Instant Pot potatoes take just 8 minutes to cook. However, it will take about 15 minutes for the pressure to build in the Instant Pot, so just be sure to take that into account.
📋 How to Make
- Peel & slice potatoes into thick rounds and add them to the Instant Pot.
- Add chicken broth and salt.
- Place lid on Instant Pot and set valve to seal.
- Cook 8 minutes.
- Heat milk & butter.
- Release pressure & remove lid.
- Drain potatoes, then combine with milk-butter mixture and sour cream.
- Mash & season.
Want to add even more flavor? Try adding in some roasted garlic before mashing the potatoes.
Can I Make these on the Stove?
- Yes! If you don’t have an Instant Pot and/or want to make this recipe on the stove, be sure to check out my recipe for Easy Mashed Potatoes with Sour Cream.
🥄 How to Mash Potatoes
- After the potatoes are cooked, I like to use my stand mixer to get them really smooth. Starting first with the paddle mixer attachment and then moving to the whip.
- You can also use a handheld electric mixer or an immersion blender.
- Or, you can go old fashioned, and use a good old potato masher if you don’t have an electronic one.
- A potato ricer also works well.
👩🍳 Variations
- Cream Cheese: Try swapping in cream cheese for the sour cream to make the potatoes less tangy, and more rich + creamy.
- Fresh Herbs: Add in your favorite fresh herbs like parsley, basil or fresh chives.
ℹ️ How to Store + Reheat
Mashed potatoes will keep in the refrigerator for up to 5 days. Store them tightly wrapped in a serving dish. To reheat, pop in the microwave for about 3 minutes, stirring every minute, until warmed through.

- Salt and pepper (to taste)
- Chives for topping
Instructions
- Place peeled and sliced potatoes in Instant Pot.

I will be making these for Thanksgiving (if not before). So delicious!! Thanks, Erin.
So easy and delicious! I love your recipes!!!
Thanks Amy!!! I appreciate it!
The potatoes were tender, totally mash ready, but too much milk. I halved the milk the second time I tried and still too much. Someone cooking a meal and expecting this to come out just so would end up disappointed. Perhaps start with a very low amount in instructions and add more to taste and consistency
