How Long to Cook Corn on the Cob
5 cooking methods with times, temperatures, and tips.
Boiling corn for more than 5-7 minutes makes it tough and starchy instead of sweet and tender. The sugars in corn start converting to starch the moment it is picked, so fresh corn needs less cooking than store-bought. Grilling in the husk at 400F for 15-20 minutes steams the kernels while adding smoky flavor. Pull back the husk in the last 5 minutes for char marks.
