This recipe for easy Instant Pot mashed potatoes is the best for those nights when you don’t have enough time or energy to make them on your stovetop.
They’re perfectly creamy and boast delicious garlic flavor. I like to garnish mine with some fresh chives and extra garlic butter when I want a super filling and decadent side dish.
If you’ve been looking for an easy way to make homemade creamy mashed potatoes, all you need to do is break out your Instant Pot and follow this classic recipe.
Creamy and delicious electric pressure cooker mashed potatoes are about to become your new weeknight go-to. Consider making a double batch…who doesn’t love leftover mashed potatoes?!

I made this recipe using my Instant Pot 6-Quart Duo Nova. It’s the perfect size for my family of four and makes releasing the steam so much easier than the standard Instant Pot.
How to Cook Garlic Mashed Potatoes in the Instant Pot
A full printable version of this recipe with ingredient measurements is available at the bottom of this post.
STEP ONE: Rinse, peel, and cube your potatoes. Add potatoes, water, and salt to the inner pot of your IP and seal the lid and valve.
STEP TWO: Cook the cubed potatoes on High for 10 minutes, then perform a quick release when the timer goes off. Carefully remove the lid.
STEP THREE: Add the sour cream, garlic (don’t use whole cloves, mince first), butter, and pepper to your Instant Pot. Use a potato masher or hand mixer to mash the potatoes until it takes on a creamy texture. You could also use a wooden spoon, but the easiest way is to use a masher or mixer.
STEP FOUR: Transfer the potatoes to a serving bowl and garnish with extra butter, chives, sour cream, or other fresh herbs. You can store your pressure cooker mashed potatoes in an airtight container if you have leftovers.
Tips to Make the Best Instant Pot Garlic Mashed Potatoes
- Use the potatoes of your choice. I’m using Russet potatoes to make mashed potatoes in the pressure cooker, but you could also use Yukon Gold potatoes, red potatoes, or baby potatoes.
- If you find that your Instant Pot garlic mashed potatoes aren’t loose enough, add a bit of whole milk or chicken broth.
- Use more herbs to add more delicious flavor. Fresh thyme and fresh rosemary are great choices. And, if you’re a total garlic lover, why not use even more garlic cloves?
- No drain, no problem. This is a no-drain garlic mashed potato recipe, thanks to the Instant Pot. They’ll cook up perfectly without having to worry about excess liquid.
- Peel your potatoes for the smoothest results.

Variations for Instant Pot Mashed Potatoes

- Roast the garlic first if you’re looking for a more complex flavor. Roasted garlic mashed potatoes for the win!
- Top with bacon bits for more crunch and savory flavor.
- Incorporate other ingredients for a more unique flavor. Pesto, mustard, and onion come to mind!
Can I Prep the Potatoes Ahead of Time?
Absolutely! This can be especially helpful if you plan on making mashed potatoes in the pressure cooker for a holiday meal. The most time-consuming part of this recipe is peeling and cutting the potatoes.
Prepare the potatoes up to 12 hours before you plan on making mashed potatoes in your IP. Simply store them in a large bowl or pot filled with water, being sure to completely submerge them.
Store them in the fridge, then pull them out and drain when you’re ready to make your dish.

- Using a potato masher is also a great option.

Love the fact that you can use a small amount of water and not have to drain the potatoes after cooking.
I’d like to make a larger batch (5 lbs), what would I have to adjust?
Hi Jean, the amounts get a little odd when you do 5lbs, but to cook 4lbs of potatoes, just double the ingredients in the recipe and keep the cooking time the same!
Thanks, do you double the amount of water used also?
Yes, since it’s no drain, the recipe will need twice as much water. 🙂
Thanks! This is one of the most useful “down to earth” recipes I’ve made in the Instant Pot.
I hear you. I try to make the kind of recipes most people would love to make and enjoy that are easy to make. Not the fancy recipes that I, as a busy mom, have no time for.
Can you use milk instead of water?
No, milk cannot be pressure cooked, so I only recommend using water and adding any milk after it’s done.
These were amazing! Thank you!
Can this recipe be cut in half? It’s just me and my husband.
Hi Janet, you would need the smaller Instant Pot in order to half the recipe due to the liquid needed to pressure cook.
How would you reheat this mash?
I would reheat the mashed potatoes in the microwave for about 1-2 minutes, stirring it up halfway through.
