Grilled corn on the cob has one big fork in the road: leave the husk on or take it off. Published guidance differs on heat, soaking and timing, so this article lays out the plain baseline method and shows where the sources disagree. It draws on Weber’s grilled corn recipe and Weber’s corn tips, plus university extension pages from the University of Nebraska–Lincoln and Utah State University. For a dressed-up version, see our Mexican street corn (elotes) recipe.
Method 1: Husked Corn, Direct Heat
Weber’s simplest approach is to husk the ears and grill the bare kernels. Its recipe calls for direct cooking over medium heat, 350°F to 450°F (175°C to 230°C), with the lid closed, until the corn is browned in spots and tender, 10 to 15 minutes, turning occasionally. The cooking grates should be brushed clean first.
Weber’s tips add two preparation points: wash the corn, dry it well, then brush it with oil to prevent burning or sticking, and add salt only after grilling, because salting first makes the corn dry out quickly.
Method 2: Husk On
Keeping the husk on gives a different result. Weber describes cooking husk-on ears on top of glowing charcoal: the husks act as a buffer against the fierce heat while the kernels steam gently, and soaking the raw ears first stops the papery husks from igniting and creates that steam.
A Weber grilling tip (written by a Weber blogger) gives this sequence:
- Pull the husk back about three-quarters of the way and remove the silk. A rubber band around the ear helps pull off stray silk.
- Soak the corn for 2 to 3 hours in ice-cold water with a couple of tablespoons of sugar.
- Grill with the husk on over indirect medium heat for 35 to 40 minutes.
How the Extension Services Compare
The university guidance is quicker and hotter.
University of Nebraska–Lincoln
Preheat the grill to high heat, 400°F to 450°F (200°C to 230°C). Shuck the corn, or leave one or two inner layers of husk on if you prefer. Brush with olive oil, salt and pepper, and pull the husk back up around the ear if desired. Grill for 8 to 12 minutes, turning every 2 to 3 minutes so each side chars. Nebraska also notes that cooking with the husks on helps retain moisture and flavor.
Utah State University
Pull the husks back, remove the silk, replace the husks and tie them with kitchen string. Soak in cold water for 5 minutes. If the corn is already husked, wrap each ear in foil. Cook on the grill, turning occasionally, until the husks are charred on all sides, 15 to 20 minutes.
Side by Side
- Husked, bare on the grate (Weber): direct medium heat, 350°F to 450°F, 10 to 15 minutes.
- Husk on, long soak (Weber tip): indirect medium heat, 35 to 40 minutes after a 2 to 3 hour soak.
- Partial husk, high heat (Nebraska): 400°F to 450°F, 8 to 12 minutes.
- Husk on, short soak (Utah State): 5-minute soak, 15 to 20 minutes.
The sources do not agree on soak length. Weber’s tip says 2 to 3 hours, Utah State says 5 minutes, and Nebraska does not mention soaking. Their timings also differ because they use different heat levels and husk arrangements.
Choosing a Method
Going by what the sources describe, husked corn on direct heat is fastest and gives browned spots, while husk-on cooking retains more moisture and takes longer. Since the times above are ranges from different publishers, judge doneness by the description they share: kernels that are tender and, for bare ears, browned in spots. Turn the ears as they cook so every side gets color.
