How to Roast Corn on the Grill: The Ultimate Guide
Roasting corn on the grill is simple: Grill the corn directly over medium-high heat, either husked or unhusked, until the kernels are tender and slightly charred. Grilling intensifies the corn’s natural sweetness, resulting in a flavorful and delicious summer treat.
The Allure of Grilled Corn
Grilled corn isn’t just a side dish; it’s a culinary experience that embodies the essence of summer. The smoky char and intensified sweetness elevate the humble corn on the cob to a gourmet delight. But why choose grilled corn over other cooking methods? It’s all about the flavor and texture. Grilling imparts a smoky depth that boiling or steaming simply can’t replicate. Plus, the slightly caramelized kernels offer a satisfying bite. This combination of flavor and texture makes grilled corn a perennial favorite at barbecues and cookouts across the globe.
Husked vs. Unhusked: The Great Grilling Debate
One of the first decisions you’ll face when grilling corn is whether to grill it husked or unhusked. Each method offers its own set of advantages and drawbacks:
Husked Corn: This method allows for direct contact with the grill grates, resulting in a more pronounced char. You can also apply flavorful rubs and marinades directly to the kernels. However, husked corn tends to dry out more quickly if not monitored closely.
Unhusked Corn: Grilling corn in the husk creates a natural steam environment, resulting in tender, juicy kernels. The husk also protects the corn from burning. The downside is that the corn may not develop as much of a smoky flavor.
Ultimately, the choice is a matter of personal preference. Experiment with both methods to find the one you enjoy most.
Mastering the Grilling Process
Regardless of whether you choose husked or unhusked corn, the grilling process is relatively straightforward. Follow these steps for perfectly grilled corn every time:
- Prepare the Corn: If grilling husked, remove the husks and silk. For unhusked corn, soak the ears in cold water for at least 30 minutes before grilling to prevent the husks from burning.
- Preheat the Grill: Preheat your grill to medium-high heat (around 350-450°F or 175-230°C).
- Grill the Corn:
- Husked Corn: Place the corn directly on the grill grates and cook for 10-15 minutes, turning frequently, until the kernels are tender and slightly charred.
- Unhusked Corn: Place the unhusked corn on the grill grates and cook for 15-20 minutes, turning occasionally, until the husks are browned and the corn is tender.
- Remove and Serve: Remove the corn from the grill and let it cool slightly before serving. For unhusked corn, carefully peel back the husks and remove the silk.
Enhancing the Flavor: Marinades and Butters
While grilled corn is delicious on its own, you can elevate its flavor with a variety of marinades and butters. Here are a few ideas:
- Marinades:
- Garlic Herb: Combine olive oil, minced garlic, chopped herbs (such as parsley, thyme, and rosemary), salt, and pepper.
- Chili Lime: Combine lime juice, chili powder, cumin, olive oil, salt, and pepper.
- Maple Bourbon: Combine maple syrup, bourbon, soy sauce, ginger, and garlic.
- Butters:
- Herb Butter: Combine softened butter with chopped herbs, garlic, and salt.
- Chili Lime Butter: Combine softened butter with lime zest, lime juice, chili powder, and salt.
- Honey Butter: Combine softened butter with honey and a pinch of salt.
Brush the corn with your favorite marinade or butter before, during, or after grilling for an extra burst of flavor.
Avoiding Common Grilling Mistakes
Even though grilling corn is simple, there are a few common mistakes that can lead to less-than-perfect results:
- Overcooking: Overcooked corn can become dry and tough. Cook the corn until the kernels are tender but still slightly firm.
- Burning: Burning the corn, especially if husked, can result in a bitter flavor. Turn the corn frequently to prevent burning. Soaking unhusked corn helps prevent the husks from catching fire.
- Not Preheating the Grill: A properly preheated grill ensures even cooking and helps prevent the corn from sticking to the grates.
By avoiding these mistakes, you can ensure that your grilled corn is always perfectly cooked and delicious.

Frequently Asked Questions (FAQs)
What kind of corn is best for grilling?
The best kind of corn for grilling is fresh, sweet corn. Look for ears with plump, milky kernels and bright green husks. Avoid ears with dry or discolored husks.
How long should I soak unhusked corn before grilling?
Soak unhusked corn in cold water for at least 30 minutes before grilling. This will help to prevent the husks from burning and create a steam environment for tender, juicy kernels.
Should I add salt to the water when soaking the corn?
No, adding salt to the water is not necessary. Soaking the corn in plain water is sufficient to prevent the husks from burning. Adding salt can potentially draw moisture from the kernels, which is not desirable.
What temperature should my grill be for grilling corn?
Preheat your grill to medium-high heat (around 350-450°F or 175-230°C) for grilling corn. This temperature will allow the corn to cook evenly and develop a slightly charred exterior.
How do I know when the corn is done grilling?
The corn is done grilling when the kernels are tender and slightly charred. You can test for doneness by piercing a kernel with a fork. If the kernel is tender and releases a milky juice, the corn is ready. For unhusked corn, the husks will be browned and the kernels will be easily pierced with a fork when cooked.
Can I grill corn directly on charcoal?
Yes, you can grill corn directly on charcoal, but you’ll need to monitor the heat more closely to prevent burning. Use indirect heat by pushing the coals to one side of the grill and placing the corn on the other side.
Can I grill frozen corn on the cob?
Yes, you can grill frozen corn on the cob, but it will take longer to cook. Thaw the corn slightly before grilling to help it cook more evenly.
How do I prevent the corn from sticking to the grill grates?
To prevent the corn from sticking to the grill grates, make sure the grates are clean and well-oiled. You can also brush the corn with oil or melted butter before grilling.
Can I use gas or charcoal for grilling corn?
You can use either gas or charcoal for grilling corn. Charcoal grilling will impart a more smoky flavor, while gas grilling is more convenient and easier to control the temperature.
What are some creative toppings for grilled corn?
Beyond butter, consider toppings like: cotija cheese and chili powder, pesto and parmesan, or bacon crumbles and chives. Experiment with different flavor combinations to find your favorites.
How long does grilled corn last?
Grilled corn is best enjoyed immediately, but it can be stored in the refrigerator for up to 3 days. Reheat the corn in the microwave or on the grill before serving.
Can I grill corn with aluminum foil?
While you can grill corn in aluminum foil, it negates some of the flavor benefits of grilling. The foil traps the steam and prevents the corn from charring. If you use foil, poke holes for steam to escape.
