Methods to Thicken Potato Soup

1. Cheese

Cheese not only enhances flavor but also acts as a fantastic thickener. Hard cheeses like cheddar and Parmesan melt smoothly into the soup, adding both flavor and texture. Simply stir grated cheese into the soup towards the end of the cooking process to create a rich, creamy consistency. Additionally, cream cheese works well to add more body.

  • Tip: To prevent the cheese from separating, stir continuously and keep the heat low.

2. Roux

Another traditional method of thickening soups is by using a roux. Made from equal parts of butter and flour, a roux is cooked until lightly browned and then mixed into the soup to add thickness and flavor.

  • How to Make Roux: First, sauté the flour and butter until they form a paste. Then, gradually add the soup broth. The roux will thicken the soup as it cooks, resulting in a smooth and rich texture.

3. Slurry

Alternatively, a slurry provides a quick way to thicken potato soup, especially when you need a last-minute fix. A slurry is made by combining cornstarch or flour with cold water and adding it to the simmering soup. Consequently, the slurry thickens the soup immediately.

  • Pro Tip: Mix one tablespoon of cornstarch with two tablespoons of cold water for a quick thickening agent.

4. Potatoes as a Thickener

Since potato soup already contains potatoes, you can use them as a natural thickener. Here are some ways to do it:

  • Instant Potato Flakes: These flakes absorb liquid and create a thicker consistency.
  • Mashed Potatoes: Add either pre-made or freshly mashed potatoes to the soup for instant thickness.
  • Extra Diced Potatoes: Cook additional diced potatoes in the soup to release their natural starches and thicken it.

Alternative Ingredients for Thickening Potato Soup

1. Cornstarch and Flour

Both cornstarch and flour are common thickeners for soups. Cornstarch provides a transparent, glossy finish, while flour creates an opaque, velvety texture.

  • For gluten-free alternatives, consider using cornstarch, arrowroot powder, or tapioca starch.

2. Instant Potato Flakes

A quick and easy way to thicken potato soup is to use instant potato flakes. Not only do they dissolve seamlessly, but they also add creaminess to the soup without affecting the flavor.

  • Best Practice: Add the flakes slowly until you reach the desired thickness.

3. Bread as a Thickener

If you enjoy a more rustic texture, use stale bread or breadcrumbs to thicken the soup. In time, they will break down in the liquid, making the soup heartier and thicker.

  • For extra flavor, try using whole-grain or sourdough bread.

If you’re interested in experimenting with different textures, sourdough discard makes a great thickener. You can find more ideas on Sourdough Discard Recipes.


Cooking Techniques for the Best Consistency

1. Timing is Key

When you add the thickener greatly affects the result:

  • For example, add a roux or slurry at the appropriate time during the cooking process. However, cheese and cream-based thickeners work best when added at the end to avoid curdling.

2. Pureeing for Natural Thickness

In addition, blending a portion of the soup with an immersion blender can achieve a naturally thick texture. Blending breaks down the potatoes and vegetables, resulting in a creamy, smooth soup without any added ingredients.


Balancing Flavor and Thickness

Balancing both the thickness and flavor of your potato soup is crucial:

  • Enhance the taste by adding seasonings like herbs, garlic powder, or pepper. Furthermore, for an extra kick, include a small splash of lemon juice or vinegar to brighten the flavors without affecting the thickness.
