How to Grill Corn on the Cob
Three tested methods for grilling sweet corn on the cob, with exact times, temperatures, and finishing ideas for sweet, charred kernels every summer cookout.
Sweet corn on the grill is one of those summer foods that gets better the less you fuss with it. The kernels caramelize, the husks add a whisper of smoke, and a swipe of butter at the end pulls it all together. The hard part is not the technique — it is picking the right method for how you want the corn to taste.
This guide walks through the three ways most home cooks grill corn: husk-off for the boldest char, husk-on for tender steamed kernels, and foil packets for a hands-off, buttery finish. You will get exact timings, prep steps, and topping ideas so any of them lands perfectly. Everything here works on a gas grill, a kettle charcoal grill, or a hot cast-iron grill pan.
The three grilling methods at a glance
| Method | Time | Heat | Result |
|---|---|---|---|
| Husk-off (direct heat) | 8–10 min | Medium-high, 425 F | Deep golden char, smoky flavor, ready fast. |
| Husk-on (soaked) | 15–20 min | Medium, 375–400 F | Steamed inside, mild smoke, no burn. |
| Foil packet | 15 min | Medium-high, 425 F | Buttery, tender kernels, zero char. |
The 5-step method
- 1.
Preheat the grill to medium-high
Fire up gas burners or bank charcoal for a two-zone setup, aiming for 400 to 450 F over direct heat. Scrape the grates hot so the corn releases cleanly and you get sharp grill marks instead of ragged tears.
- 2.
Prep the corn based on your method
For husk-off, pull off every leaf and silk and pat the ears dry. For husk-on, leave the husks intact and submerge in cold water for 15 minutes so they steam rather than flare. For foil, shuck the corn and place each ear on a square of foil with butter and salt.
- 3.
Oil and season lightly
Brush shucked cobs with a thin coat of neutral oil like canola or grapeseed. Save the butter for the finish so it does not scorch on the grates. A small pinch of kosher salt now helps the char develop flavor.
- 4.
Grill and rotate for even char
Lay the corn over direct heat and rotate a quarter turn every 2 minutes. Husked corn is done in 8 to 10 minutes when about half the kernels are speckled brown. Husk-on takes 15 to 20 minutes with the husks turning dark. Foil packets sit 15 minutes and get one flip at the halfway mark.
- 5.
Finish bright and serve hot
Roll each hot ear in soft butter and flaky salt. From there, take it in any direction: lime and chili powder, crumbled cotija and cilantro for elote, or fresh basil and Parmesan. Serve within 10 minutes for the sweetest bite.
Four small habits that upgrade every ear
- Buy corn the same day you grill it. Sweet corn starts converting sugar to starch within hours of picking, so fresher ears taste dramatically sweeter.
- Peel back a small piece of husk to check the kernels before buying. Look for plump, tightly packed rows and pale, moist silk.
- Do not salt the water if you pre-boil. Salt toughens the kernel skins. Season on the grill instead.
- For extra smoky flavor, add a small handful of soaked wood chips to a charcoal grill or the smoker box on a gas grill.
Six ways to finish grilled corn
Once the char is set, treat each cob like a canvas. These are the finishing combinations we come back to all summer.
Classic butter and salt
Cultured butter and flaky sea salt is hard to beat.
Elote-style
Mayo, cotija, chili powder, lime, and cilantro.
Herb butter
Softened butter mashed with basil, chives, and lemon zest.
Miso-honey
White miso whisked with honey and rice vinegar, brushed on hot.
Parmesan pepper
Grated Parmesan, cracked black pepper, and a drizzle of olive oil.
Chili-lime
Melted butter, lime juice, and a pinch of Tajín or ancho chile.
Storing and reheating leftovers
Cool leftover ears to room temperature, then refrigerate whole or cut off the cob in a sealed container for up to 4 days. To reheat, warm the kernels in a hot skillet with a little butter for 2 to 3 minutes — the microwave turns them soft. Grilled corn is also excellent cold, stirred into grain bowls, folded into salsas, or scattered over a summer salad.
Grilled Corn on the Cob FAQs
How long does it take to grill corn on the cob?
Husked corn takes 8 to 10 minutes over medium-high heat, rotating every 2 minutes. Husk-on corn takes 15 to 20 minutes. Foil packets take about 15 minutes.
Do I need to soak corn on the cob before grilling?
Only for the husk-on method. Soaking the ears in cold water for 15 minutes helps the husks steam the corn instead of catching fire. Husked corn does not need soaking.
Should I grill corn with the husk on or off?
Husk-off gives the strongest flavor and best char in the shortest time. Husk-on gives tender, steamed kernels with a lighter smoky note. Both work — pick based on the texture you want.
What temperature should the grill be for corn on the cob?
Medium-high, roughly 400 to 450 F. Hotter than that scorches the outside before the kernels heat through.
How do I know when grilled corn is done?
Husked corn is done when the kernels are bright yellow and speckled with brown char, and the cob feels hot in the center. Husk-on is ready when the husks are dark and pull back easily.
How do I store leftover grilled corn?
Cool the ears to room temperature, then refrigerate whole or cut off the cob in a sealed container for up to 4 days. Reheat in a hot skillet with a little butter to keep the kernels from turning rubbery.
