If you’re serious around the kitchen or if you’ve ever tried your hand at baking, then you’re probably familiar with cornstarch.
Cornstarch, as its name implies, is a powder derived from corn that’s used as a thickening agent in both cooking and baking. It can be used for sweet and savory recipes alike and it stands as a ‘must have’ for all well-stocked kitchens around the world. However, many times you go to your cabinet and realize you are out of cornstarch! So we are going to give you some options for cornstarch replacement below.
It's far from the only thickening agent at your disposal.

Cornstarch Replacements: 5 Great Substitutes
#1. CORNSTARCH REPLACEMENT: All Purpose Flour
There’s a reason why all-purpose flour has that name and it’s because it can be used for just about everything cooking related. Thickening sauces and mixtures is just one of flour’s many uses.
To use flour as a cornstarch replacement, all you need to do is double up since flour isn’t as efficient. This means that you should follow the 2:1 rule. Two cups flour per 1 cup cornstarch. 2 TBSP flour per 1 TBSP cornstarch.
You get the idea.
If you’re thinking about using flour as a replacement for cornstarch, there are a couple of things you need to keep in mind:
- Flour makes mixtures and sauces look dull and opaque.
- Flour adds flavor to the mix, which can be a good or a bad thing, depending on what you want to achieve.
- Flour takes longer to cook.
Since flour has different properties than cornstarch you’ll obtain different results so you should always plan accordingly. Regardless, flour is one of the best substitutes for cornstarch out there and one of the easiest to find if you’re in a pinch.
#2. CORNSTARCH REPLACEMENT: Arrowroot
Derived from a South American root of the same name, Arrowroot is a white powder with properties very similar to cornstarch.
In fact, it’s so similar that many people prefer always using arrowroot as a replacement for cornstarch as they believe the process through which it’s obtained is ‘purer’ and less chemical-oriented.
Here are other reasons why people choose to use arrowroot to replace cornstarch:
- It has even less flavor, making it the most neutral tasting of all thickeners
- Gluten Free
- It works well with acidic foods, something we can’t say about cornstarch
- It works with frozen foods as well
Regardless of why you’re using arrowroot as a thickener, you’ll be happy to know that there’s very little you’ll have to change as you don’t need to change the amount of arrowroot used. One TBSP of arrowroot is as good as one TBSP of cornstarch.
If you plan on using arrowroot keep in mind that it’s less stable than cornstarch, so you need to heat it up more carefully and for less time.
#3. CORNSTARCH REPLACEMENT: Rice Flour
Rice flour is a very versatile replacement for cornstarch and a powerful thickener on its own. It can be used both as a slurry or a roux and because it doesn’t clump as cornstarch does, it can be used in hot and cold liquids.
If you want to compare it to something, rice flour works similarly to wheat flour which means that you’ll need to follow the 2:1 rule when replacing cornstarch: Use twice as much rice flour as you would use cornstarch.
Besides its versatility, rice flour doesn’t change food coloring in any way, making it a great option for clear sauces and mixtures.
Here are the things you should keep in mind when using rice flour as a cornstarch replacement:
- It’s gluten free
- It works well with cold and hot liquids
- It can be used as a slurry or roux
- Works well with acidic foods
While rice flour might not change the color of food, it can change the taste slightly so keep that in mind when using it as a substitute for corn starch or any other kind of flour.
#4. CORNSTARCH REPLACEMENT: Tapioca
You’ve probably heard of tapioca before, be it as an edible root, a thickening powder or even those little balls you can find in bubble teas.
Tapioca is extracted from the cassava root and while it doesn’t have many nutritional attributes, it makes for an excellent thickener.
Being a root based thickener there are a couple of things you should take in mind when using tapioca powder as a replacement for cornstarch:
- It cooks on a pan faster than cornstarch
- It will give cookies (and other foods) a chewy texture
- Tapioca gives food a glossy look, making it a good thickener for desserts
Because tapioca cooks faster than cornstarch, you’re better off using it during the last steps of your recipe, or you risk overcooking this thickener.
Cornstarch to Tapioca ratio isn't as straightforward as flour or rice flour. You’ll need to take into consideration what you’re cooking to know how much tapioca powder you should use.
- For Baking – 1:1. Use an equal ratio of cornstarch to tapioca which means if the original recipe calls for a cup of cornstarch you should use a cup of tapioca powder.
- For Gravies and Sauces – 2:1. Double up on the tapioca. If your original recipe called for ½ cup of cornstarch, you should use 1 cup of tapioca powder.
The same applies for pie fillings of every kind.

#5. CORNSTARCH REPLACEMENT: Potato Starch
Last, but not least, on the list of things you can use as a cornstarch substitute comes potato starch.
While more popular in European cuisine, potato starch is an excellent thickener that shares a lot of properties with cornstarch, including similar cooking times and results.
As its name implies, potato starch comes from potatoes, but you’ll be surprised to find out that it has little, if any, potato aftertaste making it a perfect thickener for mixes and sauces.
While both are starches, potato starch has some unique characteristics you should keep in mind when using it as a replacement for cornstarch.
- It has no aftertaste
- Very affordable
- Passover Friendly
- It can be used at the end of the cooking process
When using potato starch instead of cornstarch, you won’t need to add anything else. These thickeners are interchangeable when it comes to measurements. That translates to 1:1, which means that if your recipe calls for ¼ cup of cornstarch you can use ¼ cup of potato starch and get the same results.
There are other thickeners out there that you can use as a replacement for cornstarch. However, the five named in this list are not only the most popular cornstarch replacements, but also the easiest to find, making them a good substitute when you’re in a hurry or for when you’re looking to try something new.
