I am completely marveled at how rich and delicious my instant pot mashed potatoes are turning out after some practice and years of making potatoes on the stovetop.

For a while, I’ve been wanting to try making potatoes in a pressure cooker and or instant pot but didn’t necessarily feel like it would really expedite things. If you’e anything like me, cooking or waiting for a long time on a weeknight to eat dinner is a drag. Though, I’m glad I took a leap and decided to try and make potatoes in the instant pot because they really came cooked to perfection.

Now, I can have these ready in about 20 minutes total. You’re going to love making these potatoes for you and your family just as much as I do.

Products to use for this recipe:

  1. Instant Pot
  2. Potato Masher
  3. Hand Mixer



When it comes to mashed potatoes – I don’t know of anyone who doesn’t enjoy eating them. They’re creamy, dreamy, and oh-so-delicious. And making them in the Instant Pot is just as simple and easy as making them on the stovetop.

In fact, this is probably the easiest way! Whether you’re incorporating a recipe like cream cheese mashed potatoes or making mashed potatoes from a hand-down family recipe, the process is essentially the same. So, let’s get started!


What’s an Instant Pot?

The Instant Pot will be your new best friend if you’ve  been trying to find life hacks and methods to make delicious home-cooked meals look effortless!

This innovative type of pressure cooker has taken the cooking world by storm, and it’s perfect for busy home cooks.

Whether you’re looking for a quick weeknight meal or something more elaborate for a weekend feast, the Instant Pot is a fresh take on a classic cooking appliance that will help you in a major way.



  • 6 medium size potatoes
  • Milk
  • Sour Cream
  • Butter
  • Garlic Powder
  • Garlic Salt
  • Salt and Pepper to taste

You’ll need about three pounds of medium-size potatoes, or 6 potatoes total. Peel and slice them into large rounds.

Something I’d like to note is that: I haven’t tried leaving the skin of the potatoes on for this recipe.



I personally like potatoes that are skinless but I’m sure leaving some skin on these mashed potatoes can’t hurt if that’s your preference. Who knows, you could be on to something even that much more delicious with skin-on instant pot potatoes?!

Upon slicing the potatoes, I find that this usually yields 4-5 round slices per potato.

By cutting the potatoes into slices it speeds up the cooking process. Cutting them into cubes can take a long time, so slicing them into rounds is a much better option.


Next, you’ll need to immerse potato rounds in water of your instant pot or pressure cooker. You’re looking at 4-5 cups of water, depending on the size of your pot. My pot is about 6-8 quartz which works great for cooking these potatoes!

Now on to cooking time! I find that covering the instant pot with a sealed lid top makes the best mashed potatoes in 8-10 minutes.

The pressure within the pot depends on if you choose to use an instant pot or a pressure cooker. The latter, has a higher pressure amount. Though, an instant pot is the standard here and cooks relatively quickly compared to the stovetop method. 

Add in about 1/2 teaspoon of salt to the pototoes in the water. This will lightly season the bare potatoes a little so they taste better. After you’ve timed 8-10 minutes on the manual timer and checked the density of your potatoes, they should be fully cooked through!

Next, drain the potatoes, and add them back into the pot. Add in salt, pepper, garlic powder, garlic salt, butter, milk, and sour cream. (The garlic powder and garlic salt is optional here).

By adding all these ingredients to the pot, it will make the mashed potatoes more velvety and easily mixable.


If you want an extra bit of flavor, add in some chives or green onions. Mashing the potatoes with all these ingredients will ensure that your mashed potatoes are full of flavor in every nook and cranny. 

You can mash the potatoes with either an electric hand blender or potato masher. I personally always use my electric hand blender because its easier and faster. Though, mashing potatoes can be fun if you make dinner as a family or have the time to enjoy cooking.

Once you are done mashing the potatoes, they should be ready to serve and devour! Be sure to test a spoonful of mashed potatoes to make sure the seasonings are up to par. You can always add in a certain seasoning or ingredients if you wish.

Otherwise, that about sums this recipe up!


Many of you may be wondering what’s the difference between The Instant Pot and a pressure cooker as well as the classic, crock pot. If you do not have an instant pot and want to use one of these other options then be sure to read some facts about these cooking appliances below before you start cooking.

Instant pot vs pressure cooker:

Some of the key differences that instant pots have compared to traditional pressure cookers is their advanced safety features and their user friendly design for beginner cooks.

With an Instant Pot, you don’t have to worry about the risk of an explosion, making it a much safer option to use. Though, you do have to be careful of scalding with an instant pot.

Instant pot vs crock pot:

Traditional crock pots are slow cookers.The Crock-Pot has been around for decades, and its most notable for its heat-insulating stoneware that keeps a steady temperature inside.

This means people can cook food low and slow and use a lower heat over a longer period of time which is the opposite usage of instant pots.

Many people utilize crock-pots as a set-it and forget it type meal who aren’t necessarily in any type of rush. Though, all instant pots these days are multi-cookers. So, they can essentially slow cook as well.

Even though, thats not what they are widely known for. Another thing to note is that Crock Pot has been improving its technology and has come out with an ‘instant cooker’ type of crock pot which is the Express Crock Multi-cooker.
