How Cornstarch Works in Soup
Understanding how cornstarch works can help you in mastering the art of thickening soups effectively. When cornstarch is heated with a liquid, it undergoes a process known as gelatinization. During gelatinization, the starch granules absorb water and swell, which thickens the soup.
To activate cornstarch properly and achieve a smooth texture in your soup, follow these steps:
Creating a Slurry
Before adding cornstarch directly into your soup pot, it’s vital to prepare a cornstarch slurry. A slurry is a mixture that ensures an even distribution of cornstarch in the liquid, preventing clumps from forming.
Steps to Make a Cornstarch Slurry
- Measure the cornstarch: Start with about 1 tablespoon of cornstarch for every cup of soup you want to thicken.
- Mix with cold water: Combine the measured cornstarch with an equal amount of cold water in a separate bowl. Stir until it forms a smooth, lump-free mixture.
Now that your slurry is ready, add it to your soup!
Incorporating Cornstarch into Your Soup
The method of introducing cornstarch into your soup can significantly impact the final texture. Here’s how you can incorporate cornstarch effectively:
Timing is Everything
It’s essential to add the cornstarch slurry at the right moment in the cooking process. Here are a few key pointers to enhance your soup-making experience:
- Post-Cooking Addition: Ideally, add the cornstarch slurry to your soup just before serving to prevent overcooking the starch and causing it to lose its thickening properties.
- Heat Adjustment: Ensure your soup is boiling when introducing the slurry. This high temperature activates the gelatinization process effectively.

The perfect balance will create a delicious soup that delights the palate.
The Science Behind Cornstarch and Thickening
Want to delve deeper into the scientific aspect of how cornstarch thickens soup? Let’s break it down:
Starch Granules and Heat
Cornstarch consists of two types of molecules: amylose and amylopectin. When heated, the heat energy causes the granules to swell and release these molecules. The amylopectin contributes to a gel-like consistency, whereas amylose thickens the liquid.
Understanding this process gives you insight into how to utilize cornstarch to achieve various thickness levels in different soups.
Potential Drawbacks to Consider
While cornstarch is a reliable thickening agent, it’s essential to be aware of potential drawbacks:
- Texture Changes: Overheating can alter the texture, leading to a starchy or slimy outcome.
- Flavor Absorption: Cornstarch is neutral in flavor, so it won’t contribute to taste, but it could dilute the flavors of seasonings in your soup if used excessively.
Storing Leftover Soup with Cornstarch
If you plan to make a large batch of soup that uses cornstarch for thickening, proper storage techniques are vital to maintaining quality. Here are some helpful tips:
1. Refrigeration
Store any leftover soup in an airtight container and refrigerate it. Soups containing cornstarch tend to thicken further when refrigerated, so you may need to add a splash of water or broth when reheating.
2. Freezing
Although cornstarch soup can be frozen, the texture may change upon thawing. To minimize this, consider freezing your soup without cornstarch and adding it fresh when reheating.
Final Thoughts: Embracing Cornstarch in Your Soup Recipes

Can cornstarch be used to thicken soups?
Yes, cornstarch can be used effectively to thicken soups. It is a popular thickening agent due to its ability to create a smooth, glossy texture without altering the flavor of the dish. When mixed with liquid, cornstarch forms a slurry that can be added to soups for thickening. Just make sure to mix it with cold water or broth before adding it to ensure it doesn’t clump.
To achieve the best results, it’s important to add the cornstarch slurry toward the end of the cooking process. Bring the soup to a gentle simmer after adding the slurry and stir continuously for about a minute until the desired thickness is achieved. Cook time should be minimal since prolonged heating can break down the cornstarch, leading to a thinner consistency.
How do you use cornstarch to thicken soup?
To use cornstarch for thickening soup, start by creating a slurry. This involves mixing equal parts cornstarch and cold liquid, such as water or broth, in a small bowl. Stir the mixture until the cornstarch is fully dissolved, creating a smooth paste without lumps. It’s crucial that the liquid is cold to prevent the cornstarch from clumping when introduced to the hot soup.
Once the slurry is prepared, slowly pour it into the simmering soup while continuously stirring. Keep the soup at a low simmer and continue stirring for 1-2 minutes. This will activate the thickening properties of the cornstarch, resulting in a thicker soup. If the soup does not reach the desired thickness after a couple of minutes, you can make and add more cornstarch slurry.
Is there a difference between cornstarch and flour for thickening soup?
Yes, there is a notable difference between cornstarch and flour when it comes to thickening soups. Cornstarch is pure starch and has about twice the thickening power of all-purpose flour, which means you’ll need less cornstarch to achieve the same level of thickness. Additionally, cornstarch gives soups a glossy finish and a smoother texture, while flour can create a more opaque appearance and may impart a slightly grainy texture if not cooked properly.
When using flour, it is best to first make a roux by cooking the flour with fat (like butter) before adding it to the soup. This method helps to develop a richer flavor and ensures that the flour is thoroughly cooked. In contrast, cornstarch can be added to the soup directly in slurry form. However, keep in mind that you shouldn’t use both thickening agents simultaneously, as they have different properties that could interfere with each other.
Can I add cornstarch directly to hot soup?
Adding cornstarch directly to hot soup is not recommended, as it can lead to clumping and an undesirable texture. Cornstarch needs to be mixed with a cold liquid to create a smooth slurry that can be integrated into the hot soup effectively. If you add cornstarch directly to the hot liquid, it often forms lumps and fails to thicken the soup evenly.
To prevent this, always create a slurry by combining cornstarch with cold water or broth before incorporating it into the soup. Once the slurry is added, gently stir the soup and let it simmer for a brief period to achieve the desired thickness. This method allows for a smooth, uniform consistency without any clumps.
How much cornstarch should I use to thicken soup?
The general guideline for thickening soup with cornstarch is to use about 1 tablespoon of cornstarch for every cup of liquid you want to thicken. This can be adjusted based on the desired thickness of the soup; if you prefer a thicker consistency, you can increase the amount. Keep in mind that cornstarch has about twice the thickening power of flour, so this is a helpful reference point.
It’s advisable to start with less and gradually add more cornstarch slurry, as it’s easier to thicken the soup than to thin it out if it becomes too thick. After adding the slurry, let the soup simmer for a few minutes to fully activate the thickening properties of the cornstarch and adjust to the desired consistency.
Can cornstarch be used in low-sodium soups?
Yes, cornstarch can be used in low-sodium soups without any issues. Cornstarch acts solely as a thickening agent and does not contain sodium or other seasonings that could alter the low-sodium profile of your soup. This makes it an excellent choice for those looking to maintain a lower sodium intake while still achieving a satisfying texture and consistency in their dishes.
When making low-sodium soups, focus on enhancing flavors through herbs, spices, and other fresh ingredients. Since cornstarch itself does not flavor the soup, you can add it without disturbing the overall taste while still creating a hearty and thick texture. Be sure to taste and adjust seasonings as needed after incorporating the cornstarch slurry.
Is it possible to freeze soup thickened with cornstarch?
While soup thickened with cornstarch can be frozen, there are a few considerations to keep in mind. Cornstarch may lose some of its thickening ability after freezing and reheating, leading to a slightly thinner texture once thawed. If you prefer a thicker soup, you might need to make a fresh cornstarch slurry and add it after reheating the soup.
For best results when freezing, consider leaving the cornstarch out until you’re ready to serve the soup. You can prepare the soup base, freeze it, and then add the cornstarch slurry directly when reheating. This way, you maintain the soup’s intended thickness and texture. Make sure to let the soup cool completely before freezing, and store it in airtight containers to prevent freezer burn.
