Cooking soups in an electric pressure cooker allows for a quick cook that offers that slow-simmered flavor. This smooth soup is delicious, and you can add a swirl of heavy cream, sour cream, or even more Greek plain yogurt on top. Top with some bacon bits, green onions, or even some seeds.

Ingredients For Instant Pot Potato Leek Soup

Ingredients for potato leek soup sitting on a white countertop.
  • Leek – You will use a stalk of leek for this recipe. It will add the perfect flavor to the soup.
  • Potatoes – Russet potatoes are what I used; they cook up perfectly in the pressure cooker.
  • Carrots – Dice up some carrots and use them to help add extra layers of flavor.
  • Garlic – You will want to mince up some garlic.
  • Butter – Use real butter, not margarine.
  • Yogurt – Plain Greek yogurt is what you will need.
  • Half and Half – So, I used half and half to create a creamy base for the soup.
  • Soy sauce – Adds a bit of depth of flavor to the soup.
  • Nature’s Seasoning – If you can’t find this seasoning, feel free to use a season-all-style type of salt.
  • Broth – Chicken, vegetable, or even beef broth works.

Substitutions and Variations

  • Vegetable Stock or Broth: For a vegetarian version of this soup, simply substitute chicken broth with vegetable stock or broth.
  • Dairy-Free / Vegan Option: Replace the butter with olive oil, half and half with coconut milk or almond milk, and Greek yogurt with a dairy-free yogurt alternative to make this recipe vegan.
  • Gluten-Free Adaptation: Ensure the soy sauce is gluten-free, or use a gluten-free tamari or coconut aminos as an alternative.
  • Additional Toppings: For added color and flavor, consider garnishing with chopped chives, grated cheese, or even a sprinkle of paprika.
  • Different Potatoes: While russet potatoes are recommended, feel free to use Yukon gold or red potatoes for a different texture and taste.
  • Extra Vegetables: To boost the nutritional value, add spinach, kale, or other greens in the last few minutes of cooking.
  • Spice it Up: For those who enjoy a bit of heat, a dash of cayenne pepper or a sprinkle of chili flakes will add a nice warmth to the soup.
  • Meat Lovers’ Option: While this is a vegetarian soup, cooked and crumbled bacon or diced ham can be added for those who prefer an extra protein boost.

  2. Select the pressure cook setting and cook for the recommended time. After cooking, carefully perform a quick pressure release.
  3. Puree the soup in batches using a stand blender or directly in the pot with an immersion blender. If the soup is too thick, stir in additional liquid until you reach the desired consistency. (Photo 4)
  4. Serve the soup hot, garnished with your preferred toppings.

Recipe Tips 

  • Saute function really helps to bring out the flavor of the vegetables. Make sure you do not skip this part.
  • Use a wooden spoon to scrape off any stuck bits on the bottom of the pot once you pour your vegetable broth in. To ensure you don’t get a burn notice.
  • You can also use chicken stock, beef, or vegetable stock. It is up to you.
  • Add in other herbs like fresh thyme, parsley, etc.
  • Clean leeks well, or you will find you can get sand and such in your soup.
  • Quick-release your soup once it is done. This is where you manually push the steam release valve.
  • Top with cheddar cheese for a cheesy twist.
  • Use a salad spinner to help clean the leeks. There is lots of dirt in leeks, and the spinning will help tremendously.
  • Use Yukon gold potatoes in replace of russets if you want.
  • For a creamier soup, add more half-and-half or even heavy cream when using the immersion blender.
  • For a dairy-free option, use coconut milk.

Alternative Cooking Methods

For those who don’t have an Instant Pot, the recipe can be easily modified for a slow cooker or traditional stovetop preparation:

  • Slow Cooker Method: Combine all ingredients except for the dairy and garnish elements in your slow cooker. Cook on low for 6-8 hours or on high for 3-4 hours. Before serving, use an immersion blender to puree the soup until smooth, then stir in the half and half and Greek yogurt for creaminess.
  • Stovetop Method: In a large pot, sauté the leeks and carrots in butter, then add the broth, potatoes, spices, and soy sauce. Simmer until the vegetables are tender, about 25-30 minutes. Proceed with blending the soup and adding the dairy ingredients as the final step before garnishing and serving.

Remember, when adapting cooking methods, the key is to ensure that the vegetables have enough time to cook through and flavors meld perfectly.

Storing Tips 

You can store the leftover soup in an airtight container. This creamy Instant Pot potato leek soup recipe does store for 3-5 days. This makes for an easy dinner or meal prep for lunches, especially in cold weather months.

Now, in terms of freezing, due to the creamy texture, the soup can become gritty once it thaws. I don’t recommend freezing the soup if you don’t care for different textures.

Serving Suggestions

This can be a meal in one, but feel free to pair it with cheesy garlic bread, an easy healthy salad, or cheesy bread rolls. Or go for it and do a club sandwich with a side of soup.

Recipe FAQs

Can I make this soup ahead of time?

Yes, you can make this potato leek soup ahead of time. After cooking, allow it to cool completely before storing it in the refrigerator. Reheat it gently on the stove or in the microwave, adding a bit more broth or half and half if it’s too thick.

What part of leeks do you eat?

The white and light green part of the leeks is the part where most prefer to eat. You can eat other areas of the leek, but you will find the best flavor is in the white and light green color.

What are the best ways to clean and prepare leeks?

The best way to clean leeks is to first slice them and then rinse under running water to remove any dirt between the layers. Alternatively, you can soak the sliced leeks in a bowl of water, then lift them out and discard the dirty water.

Is it possible to make this soup chunky instead of pureed?

Absolutely! If you prefer a chunky soup, simply skip the blending step. Instead, after cooking, you can lightly mash the potatoes with a potato masher for a soup with more texture.

Can I use a regular blender instead of an immersion blender?

Yes, a regular stand blender can be used to puree the soup. Just be careful when transferring hot liquids and blend in batches, if necessary, to avoid overfilling.

How can I adjust the thickness of the soup?

The thickness of the soup can be easily adjusted by adding more broth if it’s too thick, or by blending in more potatoes or adding a thickening agent such as cornstarch or flour if it’s too thin.
