Is Cornstarch Gluten Free?
Updated: Sep. 26, 2018
Peggy Woodward, RDN has insight (and helpful hints) for a reader who wonders, "Is cornstarch gluten free?"
DEAR PEGGY: I have celiac disease, and I wonder if I can substitute cornstarch in recipes that call for flour. Is cornstarch gluten free? —H.P., Clifton Park, New York
It’s now estimated that one in every 133 Americans has celiac disease, an immune response to the gluten found in wheat, barley and rye. For celiac sufferers, eating gluten-filled foods can damage intestines and affect nutrient absorption. (Feeling bloated? Here’s what happens when you go gluten free for two weeks.)
Corn doesn’t contain gluten, so you can substitute cornstarch in sauces and soups that use flour as a thickener. But there are a few things to remember:
- Cornstarch is a more powerful thickener than flour, so you’ll need less. Start with half as much cornstarch for the flour listed in the recipe.
- Cornstarch breaks down faster than flour, so it must be added at the end of cooking. Combine cornstarch with cold water until smooth and stir into the sauce or soup. Bring to a boil; cook and stir until thickened.
- Sauces and soups thickened with cornstarch that are chilled and reheated may not maintain the same consistency as when they’re fresh.
- You can use thickeners like arrowroot, too.
- The protein in flour gives breads, cakes and baked goods their structure. Since cornstarch lacks this protein, it can’t be used as a substitute in baked goods. Experiment with rice, tapioca and buckwheat flour and fine cornmeal instead.
- Many new gluten-free foods can be found on grocery store shelves. Look for gluten-free cake, bread and cookie mixes as well as the alternative products mentioned above.
Look out for 10 surprising foods that aren’t gluten free, though.
