Effortless Instant Pot Mashed Potatoes

It really doesn’t get easier than these pressure cooker mashed potatoes where you simply add water and potatoes to an instant pot, push a button and walk away. They’re so quick and easy (and just as delicious as our traditional mashed potatoes recipe). You can even make this a meal by cooking a meatloaf right on top of the potatoes! Check out my instant pot meatloaf recipe or browse all of my favorite Instant Pot recipes.

How to make Instant Pot Mashed Potatoes:

Cook Potatoes: Peel potatoes or keep the skins on if you prefer. Cut into quarters and add to instant pot. Pour water and salt on top of potatoes and secure lid. Pressure cook on manual/high pressure for 10 minutes then natural release for 3-5 minutes. Quick release the rest.

Mash: Drain any remaining water from the pot. Add milk, sour cream, bouillon paste, butter, salt and pepper. Mash the potatoes until all ingredients are incorporated and fluffy, just don’t over mash them or they get gummy. Taste and add more seasonings if needed.

Make Ahead and Storage Instructions:

To Make Ahead: Follow the recipe then keep mashed potatoes in the instant pot on the warm setting for an hour or two before serving. Stir and add a few splashes of milk if needed when it’s time to serve. Taste and adjust seasonings if needed.

Store leftover mashed potatoes in an airtight container in the fridge for up to five days. Rewarm on the stove or in the microwave, adding a splash of milk to make them creamy again, and season with additional seasonings, as needed.

Recipe Variations:

  • Stove Top Mashed Potatoes
  • Dairy Free Mashed Potatoes: Swap butter out for dairy-free butter and use chicken broth instead of milk and sour cream.

Ingredients
 
 

Instructions
 

  • Prep Potatoes: Wash potatoes, peel them (optional) and cut into quarters. 
  • Add to instant pot: water, potatoes and salt.
  • Cook: Secure the instant pot lid and close the pressure release valve. Select manual/High pressure and cook at high pressure for 10 minutes. When the timer beeps, allow the pressure to naturally release for 3-5 minutes, and then quick release the remaining pressure.
  • Season: Carefully open the lid and drain any extra water. Add the milk, sour cream, butter, bouillon paste, and salt and pepper. Gently Mash everything until combined, but be careful not to over mash the potatoes, which can make them "gummy" instead of fluffy. Taste and add more seasonings, as needed. 
  • Store leftover mashed potatoes in an airtight container in the fridge for up to five days. Rewarm on the stove or in the microwave, adding a splash of milk to make them creamy again, and season with additional seasonings, as needed.

Notes

Yield: Makes about 6 cups mashed potatoes. Serving size is about ¾ cup (8 servings). 
Instant Pot Size: You can double or triple this recipe for a 6 or 8 quart instant pot. The water amount and cooking time will stay the same. Just be sure you don’t go above the “fill” line”.
Potatoes: Use potatoes with a higher starch content, like russet or Yukon gold. I don’t recommend Red potatoes because they are waxier and can yield gummy tasting mashed potatoes.
Water: you need one inch of water in the bottom of the pressure cooker. Add more than 1 cup if needed. 
Make Ahead Instructions: Follow the recipe then keep mashed potatoes in the instant pot on the warm setting for an hour or two before serving. Stir and add a few splashes of milk if needed when it’s time to serve. Taste and adjust seasonings if needed.
Dairy Free Mashed Potatoes: replace butter with dairy-free butter substitute, and add chicken broth instead of milk and sour cream.

I discovered your account a few years ago via a search around Thanksgiving for IP mashed potatoes! Yours is the most accurate and very appreciated that you have options for doubling the recipe. I tried a different IP mashed potato recipe the year prior and even though I filled it to a T, it came out underdone. Thank you Lauren, for your recipes and oh btw your Asian ones are pretty legit! (I’m Chinese!) Happy (coming) holidays!

Instead of adding chicken bullion paste can you substitute chicken broth for the water?

Mashed potatoes in the insta pot? Game changer! I was in charge of bringing 15 lbs of mashed potatoes for a family gathering and this recipe literally saved me precious time. I loved how easy this recipe was and the potatoes turned out great!

Did you do all 15 pounds at once? I am also making that much for Thanksgiving and wondering if I should do it all at once or in batches.
