Pure comfort coming atcha, fast. Instant Pot Potato Soup brings the creamy, cheesy, load-’em-up goodness of classic potato soup, done one-pot pressure-cooker style. Veggie-loaded and ready in a flash, it’s nutritious with an ultra-luscious texture.
This soup is velvety rich, creamy, and cheesy just like the Panera soup I loved (and OK, I still do).
Despite how indulgent it tastes, this is not an Instant Pot potato soup with heavy cream (!)
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 delish Potato Leek Soup, this 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! And I’m betting you will too.
Further, 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 Instant Pot potato soup is simple.
Start here, then top it off to your heart’s content!
While it may not be a 3-ingredient Instant Pot potato soup, the ingredients list is fairly short and simple.
- 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.
- Cauliflower. 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 of mine (see: Instant Pot Carrot Soup and Vegan Potato Soup). It’s the best ingredient to thicken soup AND add nutrition. You won’t notice it.
- Chicken Bouillon. No chicken broth on hand? 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 without heavy cream, and Greek yogurt is high in protein, calcium, and low calorie too.
- Cheese. Sharp cheddar and 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 potato soup is the tasty toppings. Take inspiration from my Crock Pot Baked Potatoes and load up your bowl with any (or all!) of the below:
- Chives. Freshness + color. (Green onions would also be tasty.)
- Bacon. Add 2 to 3 slices bacon for a crowd-pleasing finish. Use my Air Fryer Bacon or Baked Bacon in the Oven.
- 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.
- Using sauté mode, sauté the onion and garlic in the butter.
- Pour in the water and the bouillon. Stir until dissolved.
- Add the remaining vegetables and seasoning. Pressure cook potato soup on high pressure for 10 minutes. When done, immediately vent. Purée, let cool, then stir in the yogurt and cheese. Serve hot with whatever toppings you like. (See my favorites below!) ENJOY!
- 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.
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 Instant Pot Potato Soup
- Salad. Kale and Brussels Sprouts Salad or Arugula Salad would be tasty with this soup.
- Bread. Dunk as you please with Drop Biscuits or Rosemary Olive Oil Bread.
- Vegetables. Roasted Broccolini and Roasted Carrots are both delicious options.
- Crackers. Ranch Crackers are a fun spin on a classic cracker.
- Sandwich. For a classic soup and sandwich pairing, try my BLT.
Recommended Tools to Make this Recipe
- Instant Pot. This is the Instant Pot I own and love! It’s perfect for this soup and Instant Pot Mashed Potatoes.
- Ladle. My preferred method for easily transferring soup to bowls and storage containers.
- Immersion Blender. This tool makes it a million times easier to blend soups.
Frequently Asked Questions
No, you do not need to soak potatoes before putting them in this soup.
While not totally necessary, I recommend peeling your potatoes for this soup. Leaving the skins on will create a more rustic texture that some people may find unappealing. If you decide to try the soup with the skins on, make sure you wash the potatoes very, very well.
If your Instant Pot shows a “burn” warning, it’s likely because a piece of food is stuck to the bottom of the pot. Before sealing your Instant Pot, make sure to scrape up any brown bits from the bottom of the pot with a wooden spoon.
Potato soup can quickly turn from buttery to gummy if it’s blended too much (this causes the potatoes to release too much starch). Blend your soup as needed to reach your desired consistency, but don’t blend for too long or it may affect the texture.
The soup setting on an Instant Pot is unnecessary when making this potato soup recipe and can vary between models. Simply use the Instant Pot as a soup pot with the cooking times and temperatures listed in this recipe for the perfect Instant Pot potato soup.
Instant Pot Potato Soup
- 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 1/2-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
- 1/2 cup shredded sharp cheddar cheese plus additional for serving
- 1/4 cup grated Parmesan cheese
- Chopped fresh chives for serving
- Croutons baguette, additional cheese, additional Greek yogurt (optional, for serving)
- 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.
- 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.
