Running out of cornstarch in the middle of cooking can be frustrating, but there are plenty of substitutes that work just as well. Some alternatives are better for thickening sauces, while others are ideal for baking or frying. The key is choosing the right substitute for your dish. Here’s what to use and when.
Cornstarch is known for its neutral taste and powerful thickening ability. The best substitutes should provide a similar texture without altering the flavor of your dish. Some alternatives, like flour, need to be used in larger amounts, while others, like potato starch, work as a one-to-one replacement. The key is knowing which substitute works best for your specific recipe.
Here are the best cornstarch substitutes and how to use them effectively.
Plain flour is a simple replacement for cornstarch, but because it contains less starch, you will need twice as much to achieve the same thickening effect.
Arrowroot powder is a gluten-free starch that works well in place of cornstarch. It has a neutral taste and creates a smooth, glossy finish in sauces. Unlike cornstarch, it does not break down in acidic liquids, making it useful for fruit-based fillings.
Potato starch is another gluten-free alternative with a high starch content, making it a powerful thickener. It works similarly to cornstarch but provides a slightly silkier texture.
Tapioca starch (or tapioca flour) comes from cassava root and is commonly used in gluten-free baking. It thickens at lower temperatures than cornstarch, making it a good option for puddings and pie fillings.
Rice flour is a fine, starchy powder that works well as a thickener. It has a neutral taste and produces a smooth texture in soups and sauces. It is commonly used in Asian cuisine for thickening broths.
The best cornstarch substitute depends on what you’re cooking:
For thickening sauces and soups: Arrowroot, potato starch, or flourFor baking: Tapioca starch or rice flourFor frying: Potato starch or rice flour
Each of these alternatives works well, but adjusting the quantity is important to achieve the right consistency.
