Liquids such as soup and gravy will often need to be thickened with the help of an added ingredient. There are several ingredients you can use to thicken liquids, but using cornstarch is one of the easiest and fastest methods. To thicken a liquid with cornstarch, you need to create a mixture, cook the mixture, and complete the process by altering the recipe if necessary.
Steps

Add a cooked cornstarch mixture to liquids for more control. Cooking the cornstarch first and then adding it to the mixture is an easy way to thicken a syrup , sauce or soup if you’ve found that it isn’t thick enough. Cooking the cornstarch mixture alone isn’t really any different than cooking it with the mixture. You should essentially follow the same instructions. The only difference is that you pour the cornstarch mixture into an empty pot and then add it to the liquid after it has started to bubble.
- After cooking the cornstarch mixture, add it to a heated up liquid.
- You have more control because you can as little or as much mixture to the liquid as you’d like.

Add an uncooked cornstarch mixture to liquids for a quick fix. [6] X Expert Source JoAnna Minneci
Professional Chef Expert Interview. 23 November 2021. This is the easiest and fastest method for thickening a liquid. It is best to use this method if you know for sure that you need to thicken your liquid. It is best to add the cornstarch mixture to a liquid that is only a few minutes away from being finished.

Turn the stove to a medium heat setting. Add the cornstarch mixture to a liquid that has been thoroughly stirred and simmering. Turn up the setting to a medium heat setting because the cornstarch mixture will thicken the best when it is lightly boiling. Using too much heat, however, can thin out and break down the sauce. [8] X Research source
- If you are only cooking the cornstarch mixture, you should pour it in a pan and turn it to medium heat.
-
Cook until the cornstarch and liquid mixture begins to bubble. Allow the cornstarch and liquid mixture to lightly boil for 5 or 10 minutes. After this amount of time, it should begin to bubble and thicken. Let it cook for longer if it doesn’t appear to have thickened. [9] X Research source
-
Stir the cornstarch and liquid mixture for two more minutes. Use a stirring utensil, like a wooden spoon, once the cornstarch and liquid mixture begins to bubble. Stir the cornstarch and liquid for about two more minutes. This will allow the cornstarch to be completely cooked. Then, remove the pot from the heat. [10] X Research source

Check the consistency of the cornstarch and liquid mixture. Use a spoon to check the thickness of this mixture. Allow it a few minutes to cool if you want to do a taste test. If you are happy with the taste and consistency, then you are done. If you are not happy with the consistency, then you can thin it out with water or thicken it with more cornstarch.

Thin out the cornstarch and liquid mixture with water. If you find that the sauce created by the cornstarch and liquid is too thick, you can add some water to thin it out. Start by adding another 1/4 cup (59 mL) of water. Taste it and then add more water if needed. [12] X Research source
- You may need to heat up and stir the mixture again after you add water.
-
Add more cornstarch to the recipe. You can add more cornstarch to the sauce if you find that it is not thick enough. [13] X Expert Source JoAnna Minneci
Professional Chef Expert Interview. 23 November 2021. Simply repeat the process, but use slightly less cornstarch and water than you initially used. Keep in mind that repeating this process too many times can break down the recipe due to the use of heat. [14] X Research source -
Alter the taste of the recipe if necessary. Cornstarch is one of the thickening agents that contains the least amount of fat. Fat often adds flavor to a recipe, so you may find that the recipe is less flavorful than desired after it has been thickened. If this is the case, add extra seasoning or other ingredients to the recipe to make the flavor more pleasing. [15] X Research source
- Add seasoning, like salt, in small increments to avoid over-salting or over-seasoning the recipe.
