Ingredients of Instant Pot Mashed Potatoes
When it comes to making mashed potatoes, the key is all about choosing the right ingredients. For this Instant Pot Mashed Potatoes recipe, you’ll want to gather some simple yet essential items that will elevate your spud game.
Trust me, these ingredients work together to create creamy, dreamy mashed potatoes that will have everyone asking for seconds (or thirds).
Here’s what you’ll need:
- 2 lbs potatoes (any variety you like, but russets or Yukon Golds are my go-to)
- 2 tablespoons butter (because butter makes everything better, right?)
- Up to 3/4 cup buttermilk (this is where the creaminess comes from)
- Salt and pepper (for seasoning, of course)
- 1 cup water (to help cook those potatoes in the Instant Pot)
Now, while these ingredients are the basics, you can totally personalize your mashed potatoes.
For instance, if you’re feeling adventurous, you might throw in some roasted garlic or even a sprinkle of cheese for an extra layer of flavor.
And if you’re dairy-free, you can substitute the butter and buttermilk with plant-based alternatives.
The beauty of mashed potatoes is that they can be as simple or as fancy as you want them to be.
How to Make Instant Pot Mashed Potatoes

Let’s plunge into the wonderful world of Instant Pot mashed potatoes. First things first, you’ll want to grab your 2 lbs of potatoes. I recommend using russets or Yukon Golds because they’re creamy and delicious.
Now, chop those bad boys into big chunks. No need to stress about being perfect here; we’re not trying to impress anyone with our knife skills—just get them into manageable pieces. Place those potato chunks on your Instant Pot trivet, and then pour in 1 cup of water. This is going to create the steam needed to cook those potatoes perfectly.
Now, it’s time to seal the deal. Close the lid, making sure the vent is set to sealing, and select the manual setting for 13 minutes. Yes, I know, it seems like forever when you’re hungry, but trust me, it’s worth the wait.
While the potatoes are cooking, you can take a moment to ponder life’s greatest questions—like why you didn’t double the recipe for more leftovers. Once the timer goes off, you’ll want to do a quick release (QR) of the steam. Just be careful of that hot steam; it can be a bit sassy.
Drain the potatoes and transfer them to a separate bowl. Now comes the magical part—mashing. Using a potato masher, or if you’re feeling fancy, an electric mixer, beat those potatoes until they’re nice and smooth.
Add in the 2 tablespoons of butter and up to 3/4 cup of buttermilk. This is where the creaminess comes into play, so feel free to adjust the buttermilk to your taste. Don’t forget to sprinkle in a good pinch of salt and pepper for flavor.
Give everything a good mix until it’s combined, and voilà! You’ve got yourself a bowl of Instant Pot mashed potatoes that are sure to impress. Serve them up, and watch everyone come back for seconds—because who could resist that creamy goodness?

Additional Tips & Notes
To achieve the creamiest Instant Pot mashed potatoes, I recommend using starchy potatoes like Russets or Yukon Golds, as they yield the best texture.
Don’t skip the buttermilk; it adds a wonderful tang and creaminess that regular milk can’t match. If you prefer a richer flavor, try adding garlic or cream cheese.
For an extra touch, a sprinkle of fresh herbs like chives or parsley just before serving elevates the dish.
Finally, remember to taste and adjust the seasoning with salt and pepper. These little tweaks make all the difference, ensuring your mashed potatoes are a hit every time!
