The Quick Take
Grilling corn on the cob requires medium-high heat (around 400°F) and comes down to three distinct methods. Grilling in the husk takes 15 to 20 minutes and relies on the corn's natural moisture to steam the kernels. Grilling in aluminum foil takes 15 minutes and allows you to trap butter and seasonings against the cob while it cooks. Grilling naked, directly on the hot cooking surface, takes 10 to 12 minutes and requires frequent turning to develop a caramelized, smoky char without burning the sugars.

Prepping the Ultimate Summer Side
The beauty of cooking corn over a live fire is the sheer versatility. When you build a wood or charcoal fire in the center of an Arteflame grill, the solid steel cooktop gives you a massive, naturally zoned canvas. The inner edge near the roaring fire is incredibly hot for a quick char, while the outer edge is cooler, making it the perfect staging area to gently roast foiled or husked cobs without incinerating them.
Before you start, assess your corn. Look for bright green, tightly fitting husks and plump kernels. If you are going the naked or foil route, shuck the corn completely, removing all those pesky silks. If you are cooking in the husk, carefully peel back the outer layers just enough to pull out the silk, then fold the husk back over the kernels to protect them.
For the standard grill prep, pour a little vegetable oil on three paper napkins, place them in the center of the grill, stack your firewood over the napkins, and light the paper. You will be ready to cook in about 20 minutes, giving you plenty of time to soak your husks or prep your foil packets for the grill.
Step-by-Step Instructions
- Method 1: In the Husk (The Steamer). Soak the prepped, silk-free husked corn in cold water for 15 to 30 minutes to prevent the outer leaves from catching fire. Place the soaked corn on the outer, cooler edge of your grill. Cook for 15 to 20 minutes, turning every 5 minutes until the husks are charred and the kernels are tender.
- Method 2: In Foil (The Flavor Bomb). Place a fully shucked ear of corn on a square of heavy-duty aluminum foil. Add a tablespoon of butter, a pinch of salt, and any desired spices. Wrap the foil tightly to seal in the steam. Place the packets on the grill for 15 minutes, rotating them every 5 minutes.
- Method 3: Naked (The Smoky Char). Take fully shucked, bare corn and lightly brush it with cooking oil. Place it directly on the hotter part of the flat steel cooktop, closer to the center fire. Grill for 10 to 12 minutes, rolling the cobs frequently to ensure an even, blistered char on all sides without burning the sweet kernels.
Pro Tip: When grilling naked corn on the Arteflame, pull the cobs toward the cooler outer edge of the steel cooktop as soon as they reach your desired level of char. They will stay perfectly warm without overcooking while you finish grilling your steaks or burgers in the center.
Common Mistakes to Avoid
- Skipping the soak for husked corn: If you do not soak the corn first, the dry husks will instantly ignite into a blazing torch. Soak them for at least 15 minutes, unless you enjoy the smell of burnt leaves and disappointment.
- Using cheap, thin foil: Standard foil tears easily when you turn it with heavy-duty OXO grilling tongs, leaking all your delicious melted butter straight into the fire. Always use heavy-duty aluminum foil.
- Walking away from naked corn: Corn has a high natural sugar content. If you leave it sitting in one spot over high heat, it will go from beautifully caramelized to carbonized rock in about sixty seconds. Roll it frequently!
- Forgetting the finishing salt: Sweet corn absolutely begs for a salty contrast. Skipping a generous pinch of Diamond Crystal Kosher Salt at the end is a missed opportunity for flavor perfection.
Make It Your Own
Once you master the base techniques, corn on the cob becomes a brilliant blank canvas for incredible flavors. Here is how to easily elevate your next backyard batch:
- Elote (Mexican Street Corn): Grill the corn naked for a smoky char, then slather it in mayonnaise, cotija cheese, fresh lime juice, and chili powder.
- Spicy Garlic Butter: Use the foil method and pack the wrapper with minced garlic, butter, and a heavy dash of cayenne pepper for a massive flavor infusion.
- Herb and Parmesan: Brush naked grilled corn with melted butter and roll it in a mixture of grated parmesan and finely chopped fresh parsley or cilantro.
- Bacon Wrapped: Wrap stripped cobs tightly in thin-cut bacon and grill slowly on the outer edge of the cooktop until the bacon is crispy and the corn is tender.
Frequently Asked Questions
Do I need to boil corn before grilling it?
No, you do not need to boil corn before grilling. Grilling raw corn over a live fire cooks it perfectly while preserving its crisp texture and natural sweetness. Boiling it first often leads to mushy, waterlogged kernels.
How do you know when grilled corn is done?
Grilled corn is done when the kernels are tender when pierced with a paring knife and have turned a vibrant, opaque yellow. Depending on the method, you will also see a slight char on the kernels or a blackened, dry husk on the outside.
Can I grill frozen corn on the cob?
Yes, you can grill frozen corn on the cob, but the foil method works best. Wrap the frozen cobs in foil with butter and grill for 20 to 25 minutes, allowing them to thaw and steam simultaneously without drying out over the fire.
