Cream soups are a staple in many cuisines, offering a rich and comforting experience for the palate. However, achieving the perfect consistency can be a challenge, especially when the soup turns out too thin. If you’re struggling with a cream soup that’s too watery, don’t worry – we’ve got you covered. In this article, we’ll explore the various methods for thickening a cream soup, including the use of roux, slurry, and other techniques.
Understanding the Importance of Consistency in Cream Soups
Consistency is a crucial aspect of cream soups, as it directly affects the overall texture and flavor. A soup that’s too thin can be unappetizing, while one that’s too thick can be overwhelming. The ideal consistency for a cream soup is typically smooth and velvety, coating the tongue and the roof of the mouth evenly.
The Role of Starches and Thickeners
Starches and thickeners play a vital role in achieving the perfect consistency in cream soups. These ingredients work by absorbing excess liquid and swelling, thereby thickening the soup. Common starches and thickeners used in cream soups include:
- Flour
- Cornstarch
- Tapioca starch
- Arrowroot powder
- Roux (a mixture of flour and fat)
Method 1: Using Roux to Thicken Cream Soups
Roux is a classic thickening agent used in many cream soups. It’s made by mixing flour with fat (such as butter or oil) and cooking it until it reaches a desired color. The resulting roux can then be added to the soup, where it will thicken the liquid.
How to Make a Roux
Making a roux is a straightforward process that requires some basic ingredients and attention to temperature. Here’s a step-by-step guide to making a roux:
- Melt 2 tablespoons of butter or heat 2 tablespoons of oil in a pan over medium heat.
- Add 2 tablespoons of flour and whisk until smooth.
- Cook the roux for 5-10 minutes, stirring constantly, until it reaches a desired color (white, blond, or brown).
- Remove the roux from the heat and let it cool.
Adding Roux to Cream Soups
Once you’ve made the roux, you can add it to your cream soup to thicken it. Here’s how:
- Stir the cooled roux into the soup and cook for 2-3 minutes, or until the soup has thickened.
- Season the soup with salt, pepper, and any other desired herbs or spices.
Method 2: Using Slurry to Thicken Cream Soups
Slurry is another popular thickening agent used in cream soups. It’s made by mixing a starch (such as cornstarch or tapioca starch) with a small amount of cold water or broth. The resulting slurry can then be added to the soup, where it will thicken the liquid.
How to Make a Slurry
Making a slurry is a simple process that requires some basic ingredients and attention to ratio. Here’s a step-by-step guide to making a slurry:
- Mix 1 tablespoon of starch with 2 tablespoons of cold water or broth in a small bowl.

How to Temper Egg Yolks
Tempering egg yolks is a crucial step in adding them to cream soups. Here’s a step-by-step guide to tempering egg yolks:
- Beat 1-2 egg yolks in a small bowl until smooth.
- Gradually add a small amount of hot soup to the egg yolks, whisking constantly.
- Continue adding the hot soup to the egg yolks until they’re fully tempered.
Adding Tempered Egg Yolks to Cream Soups
Once you’ve tempered the egg yolks, you can add them to your cream soup to thicken it. Here’s how:
- Stir the tempered egg yolks into the soup and cook for 2-3 minutes, or until the soup has thickened.
- Season the soup with salt, pepper, and any other desired herbs or spices.
Tips and Variations for Thickening Cream Soups
Here are some additional tips and variations for thickening cream soups:
- Use a combination of thickening agents: You can use a combination of roux, slurry, and pureed vegetables to achieve the perfect consistency.
- Experiment with different starches: Different starches have different thickening properties, so experiment with different types to find the one that works best for you.
- Add acidity: A splash of acidity, such as lemon juice or vinegar, can help to balance the flavors in your cream soup.
- Use cream or coconut cream: Adding a splash of cream or coconut cream can help to enrich and thicken your cream soup.

In conclusion, thickening a cream soup that’s too thin can be a challenge, but with the right techniques and ingredients, you can achieve the perfect consistency. Whether you use roux, slurry, pureed vegetables, or egg yolks, the key is to experiment and find the method that works best for you. By following the tips and variations outlined in this article, you’ll be well on your way to creating delicious and satisfying cream soups that will impress even the most discerning palates.
What are the common methods for thickening a cream soup?
There are several methods for thickening a cream soup, including using a roux, slurry, or puree. A roux is a mixture of flour and fat that is cooked together until it reaches a desired color, then slowly whisked into the soup. A slurry is a mixture of cornstarch or flour and liquid that is whisked into the soup and cooked until it thickens. Pureeing the soup with an immersion blender or regular blender is also an effective way to thicken it.
The method you choose will depend on the type of soup you are making and the desired consistency. For example, a roux is a good choice for a creamy soup like broccoli cheddar, while a slurry is better suited for a clear soup like chicken noodle. Pureeing the soup is a good option if you want a smooth, creamy texture.
How do I make a roux for thickening a cream soup?
To make a roux, start by melting a small amount of fat, such as butter or oil, in a pan over medium heat. Then, slowly whisk in an equal amount of flour, stirring constantly to prevent lumps from forming. Continue cooking the roux for several minutes, stirring frequently, until it reaches a desired color. The color of the roux will depend on the type of soup you are making, but a light golden color is a good all-purpose choice.
Once the roux is cooked, slowly whisk it into the soup, stirring constantly to prevent lumps from forming. Bring the soup to a simmer and cook for several minutes, or until it thickens to your liking. Be careful not to add too much roux, as this can make the soup too thick and sticky.
What is the difference between a slurry and a roux?
A slurry and a roux are both used to thicken soups, but they are made and used differently. A roux is a mixture of flour and fat that is cooked together until it reaches a desired color, then slowly whisked into the soup. A slurry, on the other hand, is a mixture of cornstarch or flour and liquid that is whisked into the soup and cooked until it thickens.
The main difference between a slurry and a roux is the way they are made and the texture they produce. A roux produces a rich, creamy texture, while a slurry produces a lighter, more gel-like texture. A slurry is also quicker to make than a roux, as it doesn’t require cooking the flour and fat together.
Can I use cornstarch to thicken a cream soup?
Yes, you can use cornstarch to thicken a cream soup. Cornstarch is a common thickening agent that is often used in soups and sauces. To use cornstarch, mix it with a small amount of cold liquid, such as water or broth, until it forms a smooth paste. Then, whisk the paste into the soup and cook until it thickens.
When using cornstarch, be careful not to add too much, as this can make the soup too thick and sticky. It’s also important to cook the soup for a few minutes after adding the cornstarch, as this will help to remove any starchy flavor.
How do I puree a cream soup to thicken it?
To puree a cream soup, you can use an immersion blender or a regular blender. An immersion blender is a handheld blender that can be inserted directly into the pot, making it easy to puree the soup right in the pot. A regular blender, on the other hand, requires you to transfer the soup to the blender and blend it in batches.
When pureeing a cream soup, be careful not to over-blend, as this can make the soup too smooth and lose its texture. It’s also important to blend the soup in small batches, as this will help to prevent the blender from becoming too full and splashing hot soup everywhere.
What are some common mistakes to avoid when thickening a cream soup?
There are several common mistakes to avoid when thickening a cream soup. One of the most common mistakes is adding too much thickening agent, such as roux or cornstarch, which can make the soup too thick and sticky. Another mistake is not cooking the soup long enough after adding the thickening agent, which can result in a starchy or raw flavor.
It’s also important to avoid over-blending the soup, as this can make it too smooth and lose its texture. Finally, be careful not to add the thickening agent too quickly, as this can cause lumps to form. Instead, whisk the thickening agent in slowly and cook the soup for a few minutes to allow it to thicken evenly.
