Using Cornstarch to Thicken Soup

Variety in everything is one of the essential characteristics of the modern world, and no one can deny it. Choose a thing or an item you require, and you will be presented with various possibilities. What makes you think food is an exception?

Food is an area of study in and of itself because there are so many various foods and cuisines to choose from, based on different parts of a country or distinct countries. Soup is one of my all-time favorite dishes. Depending on your interests and preferences, each meal will make you fall in love with it.

I enjoy a wide range of soups and enjoy experimenting with different flavors to see what combinations I can come up with. Many of you, I’m sure, share my enthusiasm for soups.

However, bearing in mind the different health problems and eating plans that come with it, another crucial topic should be addressed. With the emergence of health-related issues and a growing awareness of the critical need to care for one’s health, particularly in these times, the number of people opting for a gluten-free lifestyle has risen dramatically. As a result, it’s critical to remember this before eating any food.

Many individuals may now be questioning how they may continue to eat soups while adhering to a gluten-free diet, as wheat is a joint thickening agent in many soups.

But don’t be concerned. If you’re following a gluten-free diet, you won’t have to give up soup because an alternate ingredient may be used to thicken it. Cornstarch is that component.

Are you curious as to how it will work?

Keep an eye on this post since the topic of discussion is How to Thicken soup using cornstarch.

So, without further ado, let’s get started!

Before we look at how cornstarch may be used to thicken the soup, let’s look at the difference between Cornstarch and Flour and how this substitution will affect the outcome.

Flour vs. Cornstarch

While making this move, there are likely to be some minor changes. Let’s take a closer look at it.

In terms of calories, switching to cornstarch won’t make a difference because both flour and cornstarch have the exact calorie count. If you want to modify anything about this, you’ll have to change other components instead of the thickener.

Vitamins and minerals will be one of the most significant modifications that will occur. When looking at flour from a health standpoint, it contains several essential vitamins and minerals. On the other hand, cornstarch has a nutritional value that is either negligible or non-existent. As a result, one of the areas where this alternative would fall short is in this area. On the other hand, cornstarch would be the preferred option for individuals who follow a gluten-free diet or have celiac disease.

Now that you’ve seen the difference that utilizing cornstarch as a replacement can make, let’s have a look at how you may utilize it.

Now that you’ve decided to use cornstarch instead of flour, you should be aware of a few critical considerations before proceeding. It will help you avoid making any mistakes.

While using it, one thing to remember is that you should not add cornstarch straight to the soup since it will result in an unmixed bulk rather than adequately thickening the soup. You’ll need to make a slurry with cornstarch to thicken the soup.

Before we go any further, let’s have a look at how to make it.

Slurry Preparation

This is done to make it simpler to pour and is an important step that should not be overlooked. The slurry is a semi-liquid substance that will be made ahead of time and added to the soup. It essentially entails combining any liquid with cornstarch. Water, stock, or wine can all be used as this liquid. Each of them will have a distinct flavor profile, allowing you to select one based on your preferences. It will allow you to try out several flavors before deciding on your favorite.

I believe that one tablespoon of liquid mixed with one spoonful of cornstarch would thicken 1 cup of soup in terms of slurry. This number, however, may vary depending on your tastes. You can also play with it since it will give you different flavors, and then you can figure out what quantity of slurry is ideal for you.

One piece of advice I would make here is to use the cold liquid when preparing the slurry and then add it to the heated soup. That would be the most excellent option.

Now that the slurry has been created, we may go on to the primary portion for which all of the preparations have been made thus far: thickening the soup.

Now is the time to add our slurry to the soup since it will be ready by the time we get to this stage. Pour the cold slurry paste into the soup and mix well. Once this is done, bring the soup to a boil and continue to cook until the starch in it can no longer be tasted. You can verify if it’s cooked by tasting it once while boiling. The absence of starch would indicate that it had been adequately prepared. Allow it to boil for a few more minutes if it isn’t entirely done. Otherwise, you’re good to go with your family and friends to enjoy the soup.

As a result, cornstarch should be one of your first choices for thickening the soup. But, before we wrap off this topic, let’s have a look at some more thickening alternatives for the soup.

So, let’s get started!

Other Alternatives

In this area, too, there is much variety. Cornstarch is one of the numerous alternatives for soup thickeners. It might or might not work for you. That would be a very personal decision. Arrowroot and tapioca are two more alternatives in this group. I recommend that you try everything out and see which option works best for you.

This brings us to the end of this article.


We can sum up this post by noting that gluten-free doesn’t mean you have to give up all of your favorite foods. If you look for alternatives, you could discover an excellent and nutritious one.

You will undoubtedly produce an excellent yet nutritious soup if you follow the necessary procedures and know how to prepare it. In this post, we accomplished just that. We investigated how cornstarch may be utilized as a flour alternative in the thickening of the soup without significantly compromising the flavor.

As a result, I wish you an excellent cooking and eating experience.
