How to Make Instant Pot Potato Soup

Stir in potatoes, broth, salt, and pepper and close the lid. Turn the pressure valve to Sealing. Pressure cook on high for 5 minutes.

Once the cooking time is over, it will beep. Do a 3-minute natural release, meaning do nothing for 3 minutes. And then release the remaining pressure using the quick release method.

Open the lid and add the milk. Mash potatoes with a masher until desired consistency. The pressure cooker will have made the potatoes so tender that it won’t be difficult to mash.

Use an immersion blender for a few quick pulses. Careful not to over mix.

Serve hot garnished with your favorite toppings! My family loves classic loaded potato toppings like bacon, green onion, and grated cheese.

Tips and Notes

  • Evenly sized cubed potatoes: Chop potatoes into same size for even cooking.
  • Do not over blend your soup: Whether you use a masher or immersion blender, over blending will cause potatoes to release too much starch and they become gluey.
  • Use freshly grated cheddar cheese for the toppings: It not only tastes better but melts better and is just generally healthier. Using pre-shredded cheese comes with additives that you don’t need in a healthy soup!
  • Bacon: Bacon grease is your friend! Whether you’ve cooked the bacon in the oven or on the stovetop ahead of time, use the grease in place of the butter for the initial saute. It will add so much flavor!

What Potatoes are Best for Potato Soup?

Russets are always a go-to for making a creamy potato soup recipe.

They’re readily available in most grocery stores, they’re higher in starch and they break down easily. Which is why they make great healthy mashed potatoes, too.

I love to use them for this recipe for Instant Pot baked potatoes too!

I don’t recommend using red potatoes or Yukon gold potatoes in this type of potato soup because of their low starch level.

They are waxier potatoes so they do well in soups or stews that have potato as an added ingredient as they hold their shape better.

How Can I Make This Without An Instant Pot?

You can make this soup on the stovetop as well as the slow cooker!

For the slow cooker, toss all ingredients into the cooker, close the lid and set it for 7-8 hours on low or 3-4 hours on high. After cooking time, proceed with mashing and topping as desired.

On the stovetop, saute your onion, garlic and thyme in butter until translucent. Add all other ingredients except milk and topping.

Bring to a boil, then lower heat and simmer until potatoes are fork tender about 20-30 minutes. Proceed with mashing into desired consistency and then add desired topping.

How to Store

Store: This soup makes great leftovers when kept refrigerated in an airtight container for up to 3 days. You can also keep it in the lining of the Instant Pot if you’ve got a lid for it.

Freezing: Freeze in a glass container or resealable silicone bags. Leave extra room for expansion. Can be kept frozen for up to 3 months.

Reheating: If frozen, thaw overnight or on the counter for 6 hours. Reheat the amount you need by simmering on low in a pot on the stove top. This should take about 5-7 minutes.

You can add more broth or milk to thin it out as necessary.

FAQs

How do I thicken potato soup?

This ‘baked’ potato soup is quite thick on its own and it does continue to thicken as it cools. However, you can use a bit of cornstarch.

Grab a small bowl and whisk together cold milk (or cold water or broth) and cornstarch. Add to the pot and it will thicken it up nicely.

How to serve potato soup?

Cooked chopped bacon, freshly grated cheddar cheese, green onions or even a dollop of sour cream or Greek yogurt make loaded potato soup.

A little hot sauce or everything bagel seasoning are delicious!

Serve this soup with whole grain bread and lettuce salad, savoy cabbage salad or healthy broccoli salad.

Do you peel the potatoes for soup?

While I love the nutrients in the potato peel, for this pressure cooker potato soup peeling your potatoes gives it a silkier texture. That being said, if you don’t mind the peels in soup, feel free to leave them on.

How can I make this soup vegetarian or vegan?

For a vegetarian potato soup, use vegetable broth vs. chicken broth and skip the bacon topping.

To make Instant pot potato soup vegan, saute your onion mixture in olive oil, use vegetable broth and swap whole milk for an unsweetened non dairy milk, like almond milk, rice, soy, hemp, oat etc.

Taste may change slightly and your soup may be more thin in texture. Skip adding bacon topping.

How can I make this lower in carbs?

Try making soup with half cauliflower, half potatoes for a lower carb version.

Notes

  • Store: Refrigerate in an airtight container or right in the pot for up to 3 days.

    I love that you offer substitution options. Brilliant. Did half potatoes and added cauliflower. Delicious. Like always!

      Thank you for another great quick and easy healthy recipe! We loved it. Since we didn’t have green onion we used chives.

    I’m looking to prepare this soup in a slow cooker. I have a non-dairy family member…can I use coconut milk in place of whole milk? Merry Christmas!
    Thanks.

    Wow!!! Excellent recipe! Thanks for all the tips. This is a very forgiving recipe so you should taste and adjust to your liking. Potato size may alter how much liquid you need. Also, using low sodium broth, I had to add more salt (or Vegeta for more flavor). But it’s better to add than to have too salty. I also used whipping cream instead of regular whole milk. So creamy. I like a little heat so I added Franks Redhot original seasoning (your favorite hot seasoning will work). Now, my little secret, I add a bit (to taste) sweet Hungarian Paparika! The cheddar cheese and fresh bacon bits topped it off!
    I’m looking forward to more of your recipes!!

  4. 5 stars
    Absolutely scrumptious, Olena! Total success. I substituted half of potatoes for cauliflower, as you suggested, and also added some chopped leeks – great flavor, thanks for suggesting that too. While frying onions and garlic, I added a little bit of fresh ginger – love the kick! And last but not least, I used non-dairy milk (coconut – from a carton) and it worked well too! 🙂 This is going to be a staple in our house – thanks!

    1. So happy to hear this! And that ginger kick- what an innovative addition that sounds amazing! Thanks for the review. 🙂

    1. You don’t have to, but it will create a smoother soup without strips of potato skin in there…if you are okay with that! 🙂
