Soup is a universal comfort food that can be enjoyed in various forms and flavors, from creamy broths to hearty stews. However, one of the most common challenges cooks face when preparing soup is achieving the right consistency. A soup that is too thin can be unappetizing, while one that is too thick can be difficult to eat. In this article, we will explore the different methods for thickening soups, including the use of thickeners, reduction, and pureeing.
Understanding Soup Consistency
Before we dive into the methods for thickening soups, it’s essential to understand the factors that affect soup consistency. The consistency of a soup is determined by the ratio of liquid to solid ingredients, as well as the type of ingredients used. For example, soups made with high-starch ingredients like potatoes, corn, and beans tend to be thicker and more creamy, while soups made with low-starch ingredients like chicken, fish, and vegetables tend to be thinner and more brothy.
The Role of Thickeners
Thickeners are ingredients that are added to soups to increase their viscosity and improve their texture. There are several types of thickeners that can be used, including starches, gums, and emulsifiers. Starches, such as cornstarch, flour, and arrowroot, work by absorbing excess liquid and forming a network of molecules that thickens the soup. Gums, such as guar gum and xanthan gum, work by forming a network of molecules that traps liquid and creates a thicker consistency. Emulsifiers, such as egg yolks and cream, work by stabilizing the mixture of oil and water in the soup, creating a creamy and smooth texture.
Common Thickeners Used in Soup Making
Some common thickeners used in soup making include:
- Cornstarch: a popular thickener made from cornstarch that is commonly used in Asian-style soups
- Flour: a versatile thickener that can be used to thicken a variety of soups, from creamy broths to hearty stews
- Arrowroot: a starchy thickener that is commonly used in gluten-free and paleo recipes
- Guar gum: a gum-based thickener that is commonly used in soups and sauces
- Xanthan gum: a gum-based thickener that is commonly used in gluten-free and vegan recipes
Methods for Thickening Soups
There are several methods for thickening soups, including the use of thickeners, reduction, and pureeing. The method you choose will depend on the type of soup you are making and the desired consistency.
Using Thickeners
To use thickeners, simply mix the thickener with a small amount of cold water or broth to create a slurry, then add the slurry to the soup and stir to combine. The amount of thickener you need will depend on the type of soup and the desired consistency. As a general rule, it’s best to start with a small amount of thickener and adjust to taste, as too much thickener can make the soup overly thick and starchy.
Reduction
Reduction is a method of thickening soups by cooking off excess liquid and concentrating the flavors. To reduce a soup, simply simmer it over low heat for a prolonged period, stirring occasionally, until the desired consistency is reached. Reduction is a great way to thicken soups without adding additional thickeners, and it can also help to intensify the flavors of the soup.
Pureeing
Pureeing is a method of thickening soups by blending or processing the ingredients until they are smooth and creamy. To puree a soup, simply transfer it to a blender or food processor and blend until the desired consistency is reached. Pureeing is a great way to thicken soups that are high in fiber or have a lot of chunky ingredients, and it can also help to create a smooth and creamy texture.
Tips for Pureeing Soups
When pureeing soups, there are a few things to keep in mind. First, make sure the soup has cooled slightly, as pureeing hot soups can be dangerous. Second, use a blender or food processor that is designed for hot liquids, as these appliances are typically equipped with safety features that prevent them from overheating. Finally, be careful not to over-puree the soup, as this can create a soup that is too thin and watery.
Thickening Specific Types of Soups
Different types of soups require different thickening methods. For example, creamy soups like tomato soup and creamy broth can be thickened with heavy cream or coconut cream, while clear soups like chicken noodle soup and wonton soup can be thickened with cornstarch or arrowroot. Hearty soups like stews and chili can be thickened with reduction or pureeing, while broth-based soups like pho and ramen can be thickened with starches or gums.
Thickening Creamy Soups
Creamy soups are a type of soup that is characterized by a rich and creamy texture. These soups are typically made with a combination of ingredients like heavy cream, coconut cream, and pureed vegetables. To thicken creamy soups, you can use a variety of methods, including the use of thickeners, reduction, and pureeing. One popular method for thickening creamy soups is to use a roux, which is a mixture of flour and fat that is cooked until it is lightly browned and has a nutty flavor.
Using a Roux to Thicken Creamy Soups
To use a roux to thicken a creamy soup, simply melt a small amount of fat like butter or oil in a pan, then add an equal amount of flour and cook, stirring constantly, until the mixture is lightly browned and has a nutty flavor. Then, slowly add the roux to the soup, whisking constantly to prevent lumps from forming. The roux will thicken the soup and add a rich and creamy texture.

What are the different methods for thickening soups?
There are several methods for thickening soups, each with its own unique characteristics and uses. The most common methods include using roux, slurry, or reduction. Roux is a mixture of flour and fat that is cooked together to create a smooth, velvety texture. It is often used in creamy soups and sauces. Slurry, on the other hand, is a mixture of cornstarch or flour and liquid that is whisked together and then added to the soup. This method is commonly used in Asian-style soups and sauces.
The reduction method involves simmering the soup over low heat to reduce the liquid and concentrate the flavors. This method is ideal for soups that have a high water content, such as broth-based soups. Other methods for thickening soups include using pureed vegetables, such as potatoes or carrots, or adding ingredients like oats or barley. Each method has its own advantages and disadvantages, and the choice of which one to use will depend on the type of soup being made and the desired consistency. By understanding the different methods for thickening soups, cooks can create a wide range of delicious and satisfying soups that suit their tastes and dietary needs.
How do I make a roux, and what are its uses in soup making?
To make a roux, combine equal parts of flour and fat, such as butter or oil, in a pan over medium heat. Whisk the mixture constantly until it forms a smooth, pale paste. The roux can then be cooked for a few minutes to remove any raw flour taste and to develop a nutty flavor. The uses of roux in soup making are numerous, as it can be used to thicken a wide range of soups, from creamy broths to thick and hearty stews. Roux is particularly useful in soups that contain dairy products, as it helps to prevent the milk or cream from curdling.
The key to making a successful roux is to cook it slowly and carefully, as it can easily burn or become lumpy. It is also important to use the right type of flour, as some types of flour can create a roux that is too dense or too thin. By mastering the art of making a roux, cooks can create a wide range of delicious soups that are sure to please even the most discerning palates. Additionally, roux can be used to add flavor to soups, as it can be cooked with onions, garlic, and other aromatics to create a rich and savory base for the soup.
What is the difference between a slurry and a roux, and when should I use each?
A slurry and a roux are both used to thicken soups, but they are made and used in different ways. A roux is a mixture of flour and fat that is cooked together to create a smooth, velvety texture, as described earlier. A slurry, on the other hand, is a mixture of cornstarch or flour and liquid that is whisked together and then added to the soup. The main difference between the two is that a roux is cooked before being added to the soup, while a slurry is added raw.
The choice of whether to use a slurry or a roux will depend on the type of soup being made and the desired consistency. Slurry is often used in Asian-style soups and sauces, where a light and delicate texture is desired.
