For all of our bickering, in grade school my two younger sisters and I united around one, critical point of view: when Mom let us pick what to order for lunch, the correct answer was Panera’s baked potato soup (in a bread bowl, obviously). Years later, I still have a serious soft spot for potato soup, although these days, my first choice is this healthy, easy Instant Pot Potato Soup.

Velvety rich, creamy, and cheesy just like the Panera soup I loved (and OK, I still do), this Instant Pot potato soup is made without without heavy cream, yet it tastes absolutely indulgent.

It combines fresh ingredients like potatoes and onion with pantry staples, so it’s both wholesome and convenient.

Like my go-to classic Crockpot Potato Soup and this surprisingly zippy Potato Leek Soup, this delish Instant Pot cheesy potato soup recipe derives its creaminess from the potatoes themselves, along with cauliflower and Greek yogurt.

The end result? I like this recipe better than Panera’s potato soup!

It’s equally comforting, better for you, and at less than $2.50 per serving, it’s a serious money saver compared to eating out too.

How to Make The Best Instant Pot Potato Soup

The base recipe for this soup is simple. Start here, then top it off to your heart’s content!


The Ingredients

  • Yukon Gold Potatoes. Yukon golds have a naturally rich, buttery quality and creamy consistency that makes them the best potatoes for potato soup, though they are not the only option.

Swapping Potatoes

While Yukon golds my favorite, if you prefer Instant Pot potato soup with red potatoes, you could use them in this recipe. Russet potatoes are also classic for potato soup and work well also.

  • Cauliflower. SURPRISE! Or is it? At this point, adding raw cauliflower to vegetable soups to make them thick and creamy without changing their taste or adding unnecessary fat has become a signature move (see: Instant Pot Carrot Soup; Instant Pot Broccoli Cheese Soup; Vegan Pumpkin Soup). It’s so effective, you’ll want to make it your go-to soup strategy too.
  • Chicken Bouillon. Ever start to make a soup, only to realize that you don’t have chicken broth on hand? Or have you purchased broth, only used a portion of the carton, then had to pour out the rest? This is your solution! It will allow you to make Instant Pot potato soup without chicken broth, yet keep the same, full flavor.
  • Greek Yogurt. Instead of making this an Instant Pot potato soup with cream cheese, I used Greek yogurt. It makes this soup rich and creamy, and Greek yogurt is high in protein and low calorie too.
  • Cheese. Sharp cheddar + Parmesan make up the dynamic potato soup duo. Since these are fully flavored, you can use less, making this soup lighter, without losing a speck of flavor.
  • Onion + Garlic. A must-have for soup flavor complexity. I love that they sauté right in the Instant Pot.

Topping Instant Pot Potato Soup

One of the best parts of a potato soup is tasty toppings. Take inspiration from my Crockpot Baked Potatoes and load up your bowl with any (or all!) of the below:

  • Chives. Freshness + color.
  • Bacon. This easy Oven Baked Bacon is the best way to cook it.
  • Croutons. They add crunch and become pleasurably soft as they absorb the creamy potato soup.
  • Plain Greek Yogurt. My healthy stand-in for sour cream.

The Directions

  1. Turn your Instant Pot to sauté, and saute the onion and garlic in the butter.
  2. Pour in the water and the bouillon. Stir until dissolved.

  1. Add the remaining vegetables and seasoning. Pressure cook for 10 minutes. When done, immediately vent.
  2. Purée, let cool, then stir in the yogurt and cheese.
  3. Serve hot with whatever toppings you like. (See my favorites below!) ENJOY!

Recipe Variations and Dietary Swaps

  • Instant Pot Potato Soup with Ham. Add 3 cups of cooked and diced ham to the Instant Pot after you puree the soup. Stir the ham into the soup until warm.
  • Instant Pot Potato Soup with Sausage. Add 1 pound of ground mild Italian sausage to the Instant Pot first, sautéing the sausage until browned. Remove the sausage. Leave 2 tablespoons sausage drippings, and remove the rest. Add the onion and garlic, cooking in the drippings. Add the sausage back into the soup after you’ve pureed it, stirring until warm.
  • Gluten Free Instant Pot Potato Soup. No changes needed! Unlike many potato soups that use flour as a thickener, this recipe is gluten free as written.
  • Vegan Instant Pot Potato Soup (Dairy Free). I recommend checking out the recipe for my Potato Leek Soup, which is already dairy free/vegan. This Instant Pot Broccoli Cheese Soup also has an easy vegan option.
  • Instant Pot Vegetarian Potato Soup. Swap the chicken bouillon for a vegetable bouillon instead.
  • For those watching their carbs, this potato soup is already a fairly low carb option compared to traditional potato soups, thanks to the addition of the cauliflower.

Wine Pairing

Pair this potato soup with Riesling, Sauvignon Blanc, Chardonnay, or Pinot Noir.

Storage Tips

  • To Store. Place cooked and cooled soup in an airtight storage container in the refrigerator for up to 4 days.
  • To Reheat. Gently rewarm soup in a Dutch oven over medium-low heat on the stovetop, or you can reheat your soup in a microwave-safe bowl in the microwave until warmed through. I recommend reheating your Instant Pot potato soup with milk splashes to thin the soup as needed.
  • To Freeze. Store cooked and cooled leftovers in an airtight freezer-safe container or ziptop bag (lay flat) for up to 3 months. Thaw overnight in the refrigerator before reheating.

Freezing Tip

Potato soup can become mealy when frozen, so the texture may change slightly, but it will still be tasty! If you know you want to freeze it, I recommend ensuring you puree your soup completely, so there aren’t any potato chunks remaining.

What to Serve with Potato Soup

Recommended Tools to Make this Recipe

  • Instant Pot. This is the Instant Pot I own and love!
  • Ladle. My preferred method for easily transferring soup to bowls and storage containers.
  • Immersion Blender. Easily puree soup without moving it to a separate blender.

The Best Instant Pot

An Instant Pot speeds up cooking time and makes for easy cleanup. It’s one of my most-loved kitchen appliances!

Instant Pot Potato Soup

5 from 10 votes
The best easy, creamy Instant Pot Potato Soup. Rich and satisfying, this cheesy, healthy soup uses cauliflower to make it creamy, without heavy cream!

Prep: 10 mins
Cook: 25 mins
Total: 45 mins

Servings: 4 servings

Ingredients
  

  • 2 tablespoons unsalted butter
  • 1 small yellow onion diced
  • 2 cloves garlic minced (about 2 teaspoons)
  • 3 cups water
  • 1 tablespoon chicken bouillon
  • 1 ½ pounds Yukon gold potatoes peeled and cut into 1 ½-inch chunks, about 5 medium (you can also swap russet potatoes, though I find the flavor and texture of Yukon golds more buttery)
  • 1 small head of cauliflower chopped into florets, about 4 cups
  • 2 teaspoons spicy brown mustard
  • ½ teaspoon dried thyme
  • ½ teaspoon ground black pepper
  • 1 cup 2% plain Greek yogurt or a 7-ounce container, plus additional for serving
  • ½ cup shredded sharp cheddar cheese plus additional for serving
  • ¼ cup grated Parmesan cheese
  • Chopped fresh chives for serving
  • Croutons baguette, additional cheese, additional Greek yogurt (optional, for serving)

Instructions
 

  • Turn the Instant Pot to sauté. Add the butter and let melt, then add the onion. Cook until the onion softens and turns translucent, about 5 minutes. Add the garlic and cook 30 additional seconds, just until fragrant.
  • Add the water to the Instant Pot. Let come to a simmer (this will take several minutes), then whisk in the bouillon. Continue to stir until it is smoothly dissolved.
  • Add the potatoes, cauliflower, mustard, thyme, and pepper. Cover and seal the Instant Pot. Cook on manual (high) pressure for 10 minutes. When the cooking time is up, immediately vent to release any remaining pressure.
  • Carefully open the lid. With an immersion blender, purée the soup until smooth, or puree the soup in batches in a regular blender (be careful not to fill the blender more than halfway. Hot soup will splatter). Return any soup you pureed in the blender to the pot. Let the soup cool a few minutes, then stir in the Greek yogurt, cheddar, and Parmesan.
  • Taste and adjust the seasoning as you like. Serve hot, topped with chives, additional cheese, and a dollop of Greek yogurt as desired.

Notes

  • TO STORE: Place cooked and cooled soup in an airtight storage container in the refrigerator for up to 4 days.
  • TO REHEAT: Gently rewarm soup in a Dutch oven over medium-low heat on the stove, or you can reheat your soup in a microwave-safe bowl in the microwave until warmed through. I recommend reheating your Instant Pot potato soup with milk splashes to think the soup as needed.
  • TO FREEZE: Store cooked and cooled leftovers in an airtight freezer-safe container or zip top bag (lay flat) for up to 3 months. Thaw overnight in the refrigerator before reheating.

  1. Hi Erin,
    I’m not a fan of spicey mustard, does the greek yogurt calm it down or would it be the same if I used regular mustard?

    Thank you

    1. Hi Amy! I actually wouldn’t recommend using classic yellow mustard for this recipe. You could experiment with a ground mustard or half the amount of Dijon. I hope you enjoy the recipe if you try it!

  2.  This looks yummy! Do you think in a pinch, you could substitute frozen color flower for the fresh? Thanks so much! 
    Sheryl

    1. Hi Sheryl! I have not tried this recipe with frozen cauliflower, but you could experiment with it. I’d recommend letting it thaw completely before adding it. If you decide to experiment, I’d love to hear how it goes!

    1. Hi Stephanie! If you need to make sure this recipe is vegetarian, you could use a granulated vegetable bouillon instead.

  3. Great soup!! I love it that this potato soup recipe has cauliflower and Greek yogurt. Its so much healthier than regular potato soup – and some of the best I’ve had. Definitely restaurant worthy!
    This will be a big hit at the holidays!

    I am feeding 15+ every day over the holidays. I would love to make a double amount of this for lunch time. I have the large Insta Pot. Do you think I could double it? Would the cooking times change?5 stars

    1. Hi Susan, I’m so happy to hear that this recipe was a hit! As long as everything fits in your Instant Pot (under the max fill line), then you can certainly double the recipe, and the cooking time should stay the same. I hope everyone enjoys the recipe!

  4. This was great!  I used frozen cauliflower florets with no issues-it was maybe a little bit thinner than might otherwise be-in the future I might thaw in a colander to drain some moisture, or use a little less water.  I forgot to add the spicy mustard-was delicious without, but I’ll be sure to add it next time.  Great for a cold night, and loved that it used greek yogurt-tastes like it has sour cream in it!5 stars

    1. Hi Daniel! I have not tried the recipe this way, but you could definitely experiment. If you decide to try it, I’d love to hear how it goes!

      1. Well, I decided to follow your instructions and used the bouillon cubes. Amazing! I’m two for two with your Instant Pot recipes. Thanks again!5 stars

        1. I’m so happy to hear that this recipe was a hit, Daniel! Thank you for taking the time to share this kind review!

  5. Great recipe. The way the cauliflower thickened the soup was a revelation. It was an ingenious trick for cream substitution for cream-based soup recipes. I also used frozen cauliflower, 2% colby cheese, 1 tbsp nutritional yeast plus 1 tsp salt for the granulated chicken bouillon (which I didn’t have on hand), and–because I wanted to make a slimmed-down version of clam chowder, which is a husband favorite–2 small cans of clams after the pureeing. For clam chowder, next time I would probably omit the spicy brown mustard, but my husband loved it nonetheless. Thanks for another winning recipe!5 stars

  6. This was so easy to make and delicious. My 3 year old even asked me for leftovers for lunch today(although there wasn’t much leftover). I will definitely be making it again!5 stars

  7. Yummy … but am I missing something?  It says “This is a vegetarian Instant Pot potato soup, and I’ve added plant-based protein to make it filling.”

    But it contains chicken bouillon granules (I used a vegetarian “not chicken” base), and I’m not seeing plant-based protein.

    No complaints on the product … just some confusion.   :-)5 stars

    1. Hi Connie, I’m so happy you enjoyed this dish! If you need to make sure this recipe is vegetarian, you could use a granulated vegetable bouillon instead.

  8. A nice healthy bowl of soup. My daughter loved it… but I would have preferred much much less Greek Yogurt in it as I am not really a yogurt fan and the taste was quite overpowering. Adding this as a warning for anybody who is not a greek yogurt/sour cream fan as this is what the soup tastes like!!5 stars

  9. This is so easy to make! I love that you don’t have to add any milk or cream. I used a bag of frozen riced cauliflower and it turned out great.5 stars

  10. This was delicious! I loved the combination of the potatoes and cauliflower, and the addition of the greek yogurt and sharp cheddar really works! The only change I made was to use Better than Bouillon. I try to avoid meat as much as I can and they have a great flavor called “vegetarian no chicken base.” I do find it to be a bit salty so I used 2 TSP per the 3 cups of water called for in the recipe (rather than 3 for 3!) Hope this helps others who may be looking for a vegetarian option that does not contain chicken but mimics the flavor. I had to order the product on Amazon since most stores do not carry it. I will make this soup again – very tasty (thanks, Erin!)5 stars
