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 ½ 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.

This worked out beautifully and I did not need to put another pan on my stove. Thank you for a great recipe
This will be my go to recipe from now on. My Son in law used the left overs the next morning flattened in a buttered skillet with a little cheese on both sides to make the most incredible potato pancakes (a spoonful of apple sauce to top it off) yummy!
This recipe is amazing!!! I'm gonna use this for Thanksgiving. It's sooooo good!!!
Can these be made a day ahead of time?
Yes, you can make them up to one day before serving. Reheat genlty on the stove or slow cooker and add a little more milk or butter if needed
YUM! perfect and creamy.
Hi, I have a 6-quart Instant Pot. Could I double this recipe?
You will have to slice your potatoes and see if you can just cover them with water and have the water level below the Max fill line on your pot. Ideally, you would want the water level to be far below the max fill line, because starchy potatoes will bubble up quite a bit while cooking, and they might spit starch out of the pressure valve when you release the pressure.
If the potatoes/water level is too high up inside of your 6 quart pot, it's probably best to cook two batches back to back and combine them in a large casserole dish.

That is my question! I will try this tomorrow! God bless you, thanks so much for sharing recipe!!
Yum!! Had to replace a few things but this overall worked great! Makes a cooking novice like myself very happy!
(Used 3 cloves of garlic since I didn’t have powdered, oat milk since I ran out of 1%, and mayo since I didn’t have sour cream). All in all delicious!
So good. I'll never make on stove again
Will never make mashed potatoes any other way.!
I’ll never make mashed potatoes on the stovetop again. I’ve tried several IP Mashed Potato recipes but this is the keeper. Tastes just like good ole mashed potatoes. I added one more minute to cook time, since I like Whipped Mashed Potatoes, turned out perfect❤️. After draining, I didn’t have to use a masher, just added the last of the ingredients and stirred to perfection

Wow… DELICIOUS OMG never going back after this one! 5stars
What type of potatoes did you use for this recipe? 😊
I made this recipe last night. It’s only my second time using my instant pot. I doubled the recipe. I peeled and chopped ip the potatoes and put enough water to just cover them. I followed the directions but when they were done cooking they seemed water logged, like they took on too much water? Please help 🙂
Try only adding 3/4-1 cup water & steaming the potatoes
You have to keep potatoes in fairly large chunks or they absorb too much water while cooking.
Can I double this recipe?

Easy enough for first time mashed potato chefs. Works doubled in a 10qt instapot. Great recipe. Everyone likes….even the picky eaters!

This is a top class mashed potato recipe, my wife loved it. was able to use oat milk and non dairy sour cream due to her being lactose intolerant. I added a few smashed garlic cloves to the pressure cooker and mashed them into the final product. This is a new addition to my arsenal of sides for my dinner cooking.
My go to for making the perfect mashed potatoes! Perfect amount for a family of 5!!
This is so quick and easy. I appreciate that my trusty IP keeps the potatoes warm without them scalding or gumming up. I use half unsalted butter and half Kerrygold garlic herb butter, less sour cream. The flavor is amazing.
Perfect way to make mashed potatoes. Unless I need to make them on the stove to make a larger amount, I will always make them this way. Timing is perfect. No hovering over the stove waiting for water to boil. Thanks!!
Is the cook time the same for 5 lbs potatoes?
So easy!! They turned out amazing!
