4-Ingredient Potato Soup in the Instant Pot

This 4-ingredient potato soup is so fast an easy to make with the help of a pressure cooker.  And all that with only 4 simple ingredients! You will love this simple soup that is perfect for a light meal or side dish.

What are the 4 ingredients in this potato soup?

First, a quick disclaimer.  If you count it up, you will see that there are actually 6 ingredients listed for this recipe.  I decided to opt for the rules used on shows like Chopped or Top Chef, and count olive oil, salt and pepper as “freebies” that do not count toward the ingredient total.  If you remove those, you will see there are only 4 ingredients remaining.  Here are the ingredients that you will need:

  • Olive oil
  • Onions- I used yellow onions for this soup for their lighter flavor as compared to white or purple onions
  • Yellow potatoes-these potatoes are softer than russet potatoes and therefore cook more quickly, you cannot substitute russet potatoes in this dish without changing the cooking time
  • Chicken broth- If you prefer you could substitute vegetable broth for the chicken broth
  • 1 wheel of laughing cow cheese, creamy garlic and herb flavor
  • Salt and pepper to taste

How do I make 4 ingredient potato soup?

  • Begin by preparing your ingredients.  Peel and dice the onions.  Peel and chop the potatoes into ½” cubes.  Remove the wrappers from the laughing cow wedges, cut into small pieces and set aside.
  • When the ingredients are ready set the Instant Pot to saute.  Add the oil and allow to heat until it begins to shimmer.  Add the onions and cook, stirring occasionally until they soften and become translucent.  That should take 3 to 5 minutes.  Turn off the saute feature.
  • Add the potatoes and chicken broth the the bowl of the Instant Pot.  Set the cooking time to manual high pressure for 10 minutes.  When the cooking time is done, quick release the pressure.
  • Add the laughing cow cubes and stir until melted.
  • Use an immersion blender to puree the soup to smooth.  If you do not have an immersion blender, you may transfer the soup to a food processor or blender to puree.
  • Taste for salt and pepper and serve.

Topping ideas for 4-ingredient potato soup?

On its own, this can be a very light soup, it works great for when you don’t want a heavy meal or want to have your soup as a side dish.  This potato soup is thinner than a lot of the “loaded” this or thats of recent years and more reminiscent of an older style potato soup.  So, the choice of how to top the soup is really going to determine just how filling, or not, you find it.  Here are some ideas:

  • Crispy Bacon Bits: Bacon and potatoes are a classic flavor combination, so it’s no surprise that crispy bacon bits make a great topping for potato soup. Cook some bacon until it’s crispy, then crumble it into small pieces and sprinkle it on top of the soup.
  • Shredded Cheese: Adding shredded cheese to potato soup is a simple way to add extra flavor and creaminess. Cheddar, Parmesan, and Gruyere are all great options.
  • Sour Cream: A dollop of sour cream on top of a bowl of hot potato soup adds a tangy flavor and a creamy texture. You can also add some chopped herbs or scallions to the sour cream for extra flavor.
  • Chives or Scallions: Fresh herbs like chives or scallions make a great topping for potato soup. Simply chop them finely and sprinkle them on top of the soup.
  • Croutons: Adding crispy croutons to potato soup is a great way to add some crunch and texture. You can make your own croutons by toasting cubes of bread with olive oil and seasoning, or buy them pre-made.
  • Roasted Vegetables: Roasted vegetables like broccoli, cauliflower, or carrots make a great topping for potato soup. Simply roast them in the oven until they are tender and slightly crispy, then sprinkle them on top of the soup.

Can you make potato soup without flour?

Absolutely, our version does not use any flour. If you do need to thicken your potato soup here are a few other things you can try:

One way to thicken potato soup without flour is to use starchy potatoes like russets or Yukon Golds. These potatoes break down when cooked, releasing their starch and helping to thicken the soup naturally.

Another option is to use an immersion blender to puree some of the potatoes in the soup. This will help to thicken the soup and give it a creamy texture without the need for flour.

You can also add cream or a non-dairy alternative like coconut milk to the soup to give it a creamy texture and thicken it up.

Finally, you can add a cornstarch slurry to the soup. Mix 1 tablespoon of cornstarch with 1 tablespoon of cold water until smooth, then stir the slurry into the soup. Allow the soup to simmer for a few minutes until it thickens.

So, there are plenty of ways to thicken potato soup without using flour. It’s all about finding the method that works best for you and the ingredients you have on hand.

Can I make 4-ingredient potato soup without chicken broth?

Absolutely, vegetable broth can easily be substituted.

  1. Grilled Cheese: A classic grilled cheese sandwich is a great choice to serve with potato soup. The gooey, melted cheese and crispy bread complement the creamy soup perfectly.
  2. BLT: A BLT sandwich (bacon, lettuce, and tomato) is another tasty option. The saltiness of the bacon and the freshness of the lettuce and tomato provide a nice contrast to the rich, creamy soup.
  3. Ham and Cheese: A ham and cheese sandwich is a simple yet delicious choice. The saltiness of the ham pairs well with the creamy potato soup, and the melted cheese adds an extra layer of flavor.
  4. Turkey and Avocado: For a lighter option, consider a turkey and avocado sandwich. The turkey provides protein while the avocado adds a creamy texture and healthy fats. The flavors of this sandwich complement the potato soup without overwhelming it.
