Cornstarch Substitutes?

Cornstarch is most often used in small amounts as a thickening agent and so a cornstarch substitute is pretty easy to find in your pantry.

If you run out, you will need to substitute for cornstarch when making gravies or sauces so that they will become rich and thick like a good sauce should be. If you just leave cornstarch out of your process, your sauce will be very thin and watery. You do not want to leave this important ingredient out of your recipe. So, be sure to check our cornstarch substitution table in order to pick a suitable cornstarch substitute.

Listed below are several alternatives to use when you need a cornstarch substitute.

Cornstarch Substitute:

Cornstarch Amount Substitute
Cornstarch substitute 1 Tablespoon 2 Tablespoons All-purpose Flour
*OR* 2 Tablespoons Tapioca (granulated)
*OR* 4 teaspoons Tapioca (instant)
*OR* 1 Tablespoon Arrowroot
*OR* 1 Tablespoon Potato Starch


But remember, when making a substitute for cornstarch be sure to measure accurately for best results.

These cornstarch substitute suggestions are best when using cornstarch as a thickening agent, and will make little or no difference in the finished gravy or other sauce – whichever alternative for cornstarch that you choose. Some cornstarch substitutes may alter slightly the taste, texture, weight, or moisture content of the finished product but it will be a slight difference. Whether this is good, bad or indifferent depends on your tastebuds, but we’ve tried others and feel that these are the best alternatives in a pinch and make the least difference in resulting recipes.

Hopefully you found a cornstarch substitute to suit your needs.
