How To Make Cornstarch Chunks Step-By-Step

Cornstarch is a common household pantry filler generally used to thicken sauces, stews, and gravies. Cornstarch is made from a part of corn known as the endosperm, which contains most of the starch in corn. 

Cornstarch is considered a processed food containing very little nutritional value. Even though its lacks nutrition, cornstarch is a multifunctional ingredient that is extremely useful in the kitchen. Something that most people don’t think about making with their cornstarch is cornstarch chunks. 

Cornstarch chunks can be eaten as is, or they can be used as parts of a meal. We will cover how you can use cornstarch chunks later in this article. Before we get there, though, you need to know how to make the cornstarch chunks in the first place. Here is the step-by-step method for you to follow:

Step 1 – empty a box of corn flour onto a plate or bowl, ensuring you get all the cornstarch out of the box. 

Step 2 – using a spoon, place four or five tablespoons of the corn flour back into the box or into a container you have chosen that is safe for your preferred cooking method. 

Step 3 – shake the cornstarch container to help remove some of the air between the cornstarch particles. 

Step 4 – repeat this process until all the cornstarch is in the container. 

Step 5 – using a glass with a flat bottom, press the cornstarch down as hard as possible to get rid of all the air in the cornstarch. Move the glass around to ensure you press all the cornstarch down and release the air. This is the critical part of this process, so take your time to ensure all the air is out of the cornstarch. 

Step 6 – wrap the container tightly in aluminum foil once all the air is out of the cornstarch. 

Step 7 – Use one of the cooking methods mentioned below to cook your cornstarch. 

Step 8 – Place your cornstarch in the freezer overnight. 

Step 9 – the next day, take the cornstarch out of the freezer. You should be able to break the cornstarch into chunks and use it as you please. 

Below we will cover two different methods you can use to cook your cornstarch and make cornstarch chunks. 

How To Make Cornstarch Chunks In The Microwave 

The first cooking method you can use to make your cornstarch chunks is cooking the cornstarch in the microwave. You can do this in two ways. First, you could carry on from the step-by-step method above but skip the aluminum foil step. 

Then you can place your cornstarch into the microwave for 6 minutes on high. This will cook the cornstarch nicely, and then you can put it in the freezer overnight. 

The other way you can cook cornstarch in your microwave is to mix some water and oil into it once you have removed all the air from the cornstarch. Only use enough water and oil to make the cornstarch form clumps in the container. 

Then microwave the cornstarch on high for 6 to 8 minutes and freeze overnight. This will also make good cornstarch chunks, and some people prefer this method as it can add a tiny bit of flavor and texture to the cornstarch. 

How To Make Cornstarch Chunks In The Oven

Another technique you can use to cook your cornstarch is in the oven. This is the more traditional method of making cornstarch chunks, and you cannot go wrong with it. You will need to cover your cornstarch in aluminum foil for this method. 

Preheat your oven to 425°F and place the wrapped cornstarch into the middle of your oven. Allow the cornstarch to cook for one and a half hours. Once it’s cooked, take the cornstarch out of the oven and allow it to cool completely. 

When the cornstarch has cooled, place it in your freezer and freeze it overnight. You can take the cornstarch out the next day and break it into chunks. You can eat the cornstarch as is or use it in a meal.

Once you have made your cornstarch chunks, you might be wondering how to use them in your kitchen. There are many ways you can use cornstarch chunks. Firstly, you can eat the cornstarch chunks if you want to. 

If you want to eat them as cornstarch chunks, use the microwave cooking method and put water and oil in the cornstarch before cooking, as this will help slightly with the taste. This method can also make the cornstarch chewy, so you can chew it like gum. 

You can use cornstarch chunks in the same way you use cornstarch. You can use them to thicken sauces, soups, and stews. You can also use them in baking to help create light and fluffy cakes and pie pastries. 

If you have a young child, you can also use cornstarch chunks in a sensory play bin for them to play with without worrying about them eating it as it is edible. 

What Do Cornstarch Chunks Taste Like?

Cornstarch chunks don’t have a flavor. Most people describe it as like eating a tasteless powder. So, even though you can eat cornstarch chunks, it might not be a great idea as there will be no flavor, and you will most likely cough the powder everywhere if you aren’t used to it. 

However, if you like eating cornstarch chunks for the texture of the chunks, or you want to try eating them, then no harm will come from this unless you eat a large amount at once. 


Cornstarch chunks are easy to make, and you can use a microwave or oven to make them. The most important stage of making cornstarch chunks is getting all the air out of the cornstarch before cooking it. Once you get this stage right, you will have no problems making the chunks.
