How to Thicken Potato Soup: Methods and Tips

When it comes to thickening your potato soup, the traditional method involves using other ingredients such as potato starch, corn starch, or rice flour. However, you can also use potatoes themselves, a method that involves turning the potatoes into a puree to thicken the soup. If you are curious about how to thicken your potato soup, this article will provide some valuable tips.

Using Potato Starch

If you can obtain potato starch, it is an excellent option for thickening your soup. However, for those who may not have potato starch, alternatives such as corn starch, rice flour, or besan flour can be used. To thicken your soup with a starch-based method, dissolve a small amount of the starch in a little bit of warm or room temperature water. Afterward, add this mixture to the soup gradually and stir continuously to ensure it disperses evenly and does not lump up.

Using Potatoes to Thicken Soup

When thickening potato soup, it is best to use potatoes themselves. Here's a step-by-step method on how to do this:

Slightly caramelize onions in butter.

Add cubed, peeled potatoes and chicken stock to the pot. Simmer the potatoes until they are very tender.

Purée the mashed potatoes in a blender and add them back to the soup.

Simmer the soup for a few more minutes to ensure the flavors meld and the soup reaches the desired consistency.

For an additional touch, garnish each serving with chopped bacon bits and green onions.

Alternative Thickeners: Corn Starch and Roux

An alternative to potato starch or pureeing potatoes is to use cornstarch. It is important not to directly add cornstarch to hot liquids as it can lump. Instead, mix a small amount of cornstarch with a small amount of water to form a paste. Gradually introduce this paste to the soup and stir continuously.

If you prefer a roux-based thickener, you can make one by combining flour and oil in a pan. Stir the mixture until it thickens, then add it to the soup. This method works well for achieving a smooth thickening in the soup.

Adding More Potatoes or Potato Flakes

Another simple method to thicken potato soup is to add more potatoes or potato flakes. However, be cautious with potato flakes as they can thicken the soup quite quickly and outweigh the need. Ensure you are using real potato flakes, as other types of flakes may not be suitable.

Using Cheese for a Creamy Texture

If you want a richer texture and a creamy finish, you can also opt for adding cheese to your potato soup. Adding cheese not only thickens the soup but also adds delicious flavor and a creamy mouthfeel. Consider using a type of cheese that melts well and will blend nicely into the soup.
