We all love the traditional dishes served during the holidays, but it is nice to tweak it just a bit! These Instant Pot garlic mashed potatoes do just that. Packed with flavor they’re a great easy Instant Pot recipe added to our list of more than 100+. (affiliate links present, originally published 10/21)

Best Instant Pot Mashed Potatoes

You can make this with any brand of electric cooker you have at home. I mean I have them all including a Crockpot Express, Mealthy and of course my Ninja Foodi multi cooker. Use the same directions for all of them listed below.

We made “plain” Ninja Foodi mashed potatoes years ago and used this same method, except with LOT more garlic and goodness. I don’t only make these when family comes over though. It is so easy to throw together, and cheap as heck that they’re served a few times a month too.

If you are new to pressure cooking we have a lot of easy one pot meal recipes for you here. To begin with let’s start with a few basic tips:

For reference, this is the pressure cooker I have (a 6 quart) and use for all recipe creations.

Instant Pot Garlic Mashed Potatoes NO Drain

That is right!! There is no colander needed to drain the water out before you prep these. That is super handy and makes it a lot safer too. No scalding liquid that can potentially burn you. Instead you just cook them with broth to soften and then add all the other ingredients at the end when you mash it all together.

We do enjoy Instant Pot cauliflower mash here and there too if I am trying to cut down carbs a bit. Surprisingly they taste very close to these if you use the same ingredients to add lots of flavor.

I recommend using fresh garlic for this. Air fryer garlic is the all time best. I’ll admit that I do have a jar of minced in my fridge in case I run out but that is my standby. Diced onions are optional but add more taste and a bit of texture as well to every bite.

Ninja Foodi Garlic Mashed Potatoes

You can make this as an easy Ninja Foodi recipe, in your Mealthy or Crockpot Express. All you are using is the high pressure function and they all have this. Timing would remain the same for all electric pressure cooker brands so just follow it exactly as directed below in the printable recipe card.

  1. Washed and sliced Russet or Yukon Gold potatoes with the skin on or taken off like these. The only real difference is the texture and nutritional value is better when left on. Red take a bit longer because they are firmer.
  2. Chicken broth or water
  3. Minced jarred garlic or fresh garlic cloves and onions with olive oil in order to soften on saute
  4. Sour cream
  5. Heavy cream
  6. Garlic salt
  7. Potato masher

Add salt and pepper to taste at the very end. You can always season more when they are done and ready to serve, you can’t unsalt it once it’s in there.

Homemade Garlic Mashed Potatoes

Keep in mind that the thicker you slice your pieces the chunkier they will be. If you want them really smooth cut them into chunks like you see here.

What is the best potato for mashed potatoes and why?

Yukon Gold are said to be the smoothest and best to use. They have more starch than others but second to those would be Russets. Remove skins to make them very smooth, for more texture leave them on.

When it comes to the add ins at the very end you can add more or less than listed below. If you want them really thick you might only add a bit of the cream. Some like it real smooth and choose some cream cheese as well. For a healthier choice you could use broth instead to thin them out.

Start to finish this takes under 30 minutes which means you can pressure cook Instant Pot frozen roast first, and then when that is resting you can throw in potatoes to cook.

Potatoes in the Instant Pot

You can make other versions like our cheesy bacon ranch potatoes in your pot too. Feel free to add a bit of sour cream to those too for a creamier version. Want to leave petite baby taters whole and serve them just like that? We show you how to make those pressure cooker baked potatoes this way.

There are SO many ways to make these whether they are left whole, diced, or mashed as you see here. Adding in different herbs, butter, ranch seasoning, bacon bits and other add ins will make it taste different every time.

I will tell you this is my kids favorite side dish of all times. I mean even when they first starting eating solids they would want more and more. Mushrooms are probably my second favoritest.

Instant Pot Mashed Potatoes with Garlic

Want to really amp this up?? Dice up some air fryer garlic and sprinkle a little of that on the top when you serve up this baby. OH Yeah.

If this is for the holiday season you could combine these two favorites to make green bean mashed potato casserole too.

What do you do with these if you have any leftovers. Wait until they are room temperature to do anything first off. Then spoon what is left into airtight containers. Add as much as you’d want to reheat in one sitting the next day. The least amount of air left in the container or bag the better to keep them moist.

Reheating them is easy. Either make them into air fryer mashed potato balls or transfer to a microwave safe bowl and heat for 30 seconds and then stir. Continue to do this until they are as hot as you’d like them to be. For added yum sprinkle shredded cheese on top for the last warming.
