How Long to Grill Corn on the Cob? Unveiling the Perfect Cook Time
Grilled corn on the cob is a summer staple. The ideal grilling time, depending on whether you’re grilling shucked or unshucked corn, usually falls between 8-25 minutes. This results in kernels that are tender, slightly charred, and bursting with natural sweetness.
The Allure of Grilled Corn: More Than Just a Side Dish
Grilled corn on the cob elevates a simple vegetable into a culinary delight. The direct heat caramelizes the natural sugars in the corn, creating a smoky, slightly sweet flavor that’s irresistible. Beyond the taste, grilling offers several advantages:
- Enhanced Flavor: The Maillard reaction occurs during grilling, creating hundreds of new flavor compounds.
- Nutrient Retention: Grilling can help retain more nutrients compared to boiling, as they’re not leached into the water.
- Ease of Preparation: With minimal ingredients and simple steps, grilling corn is a quick and easy way to add a vibrant side dish to any meal.
- Versatility: Grilled corn can be enjoyed plain, seasoned with butter and salt, or used as an ingredient in salads, salsas, and other dishes.
Choosing Your Corn: Freshness Matters
The secret to truly delicious grilled corn starts long before it hits the grill. Selecting the freshest corn is crucial. Look for these indicators:
- Husks: The husks should be bright green, tightly wrapped around the cob, and slightly damp. Avoid corn with dried-out or yellowing husks.
- Silk: The silk protruding from the top of the husk should be golden brown and slightly sticky.
- Kernels: Feel the kernels through the husk. They should be plump and full.
- Weight: The corn should feel heavy for its size, indicating moisture content.
The Two Paths: Shucked vs. Unshucked Grilling
There are two primary methods for grilling corn: shucked and unshucked. Each method has its own advantages and disadvantages.
Shucked Corn: This method involves removing the husks and silk before grilling. It allows for direct contact with the heat, resulting in a more pronounced char and smoky flavor. However, it can also dry out the corn if not properly monitored.
Unshucked Corn: Grilling in the husk provides a natural steaming environment, resulting in moist and tender corn. The husk also protects the kernels from burning. This method takes slightly longer but is more forgiving.
The Grilling Process: Step-by-Step
Here’s a breakdown of the grilling process for both shucked and unshucked corn:
Shucked Corn:
- Prepare the corn: Remove the husks and silk completely.
- Preheat the grill: Preheat your grill to medium-high heat (350-450°F).
- Oil the grates: Lightly oil the grill grates to prevent sticking.
- Grill the corn: Place the corn directly on the grill grates.
- Turn frequently: Grill for 8-12 minutes, turning every 2-3 minutes, until kernels are lightly charred and tender.
- Serve: Remove from the grill and serve immediately.
Unshucked Corn:
- Soak the corn: Soak the corn in cold water for at least 30 minutes to prevent the husks from burning.
- Preheat the grill: Preheat your grill to medium heat (300-350°F).
- Grill the corn: Place the corn directly on the grill grates.
- Turn occasionally: Grill for 15-25 minutes, turning every 5-7 minutes, until the husks are lightly charred and the corn is tender.
- Cool slightly: Let the corn cool slightly before removing the husks and silk.
- Serve: Remove the husks and silk and serve immediately.
Seasoning and Serving: Beyond Butter and Salt
While butter and salt are classic choices, the possibilities for seasoning grilled corn are endless. Consider these options:
- Spiced Butter: Mix softened butter with chili powder, cumin, paprika, and lime juice for a Southwestern flair.
- Herb Butter: Combine butter with fresh herbs like parsley, cilantro, and chives.
- Parmesan Cheese: Sprinkle grated parmesan cheese over the hot corn for a savory treat.
- Mexican Street Corn (Elote): Spread mayonnaise, cotija cheese, chili powder, and lime juice on the corn.
Common Mistakes to Avoid
Grilling corn is relatively simple, but avoiding these common mistakes will ensure perfectly cooked corn every time:
- Overcrowding the grill: Overcrowding can lower the grill temperature and result in unevenly cooked corn.
- Using too high of heat: High heat can char the corn too quickly, leaving the kernels undercooked.
- Ignoring the “ear test”: Gently squeeze the corn through the husk. If it feels soft and yields easily, it’s likely done.
- Not soaking unshucked corn: This can lead to burnt husks and dry corn.
Grilling Time Summary Table
| Method | Grill Temperature | Grilling Time | Expected Results |
|---|---|---|---|
| Shucked | Medium-High | 8-12 minutes | Charred kernels, slightly sweet and tender |
| Unshucked | Medium | 15-25 minutes | Moist and tender kernels, steamed flavor |
Frequently Asked Questions About Grilling Corn
How do I know when my corn is done grilling?
For shucked corn, look for lightly charred kernels and a tender texture. You can test for tenderness by piercing a kernel with a fork. For unshucked corn, the husks will be lightly charred. You can gently squeeze the corn through the husk. If it feels soft and yields easily, it’s likely done. Remember to let the corn cool slightly before removing the husks, as the steam inside can be very hot.
Can I grill frozen corn on the cob?
Yes, you can grill frozen corn on the cob, but it will require a longer grilling time. Thaw the corn slightly before grilling. Expect to add about 5-10 minutes to the grilling time. Keep a close eye to prevent burning.
Should I soak shucked corn before grilling?

What’s the best way to remove the silk from corn?
The easiest way to remove the silk is to peel back the husks, remove the silk, and then pull the husks back up over the corn.
