How Long to Cook Corn on a Grill?
Grilled corn is a summertime staple, and perfectly cooking it requires knowing the right timing. Grilling corn directly on the grill typically takes 8-10 minutes, while grilling in the husk requires 15-20 minutes, ensuring sweet, tender kernels every time.
The Irresistible Allure of Grilled Corn
Grilled corn on the cob is more than just a side dish; it’s a culinary celebration of summer. The smoky char, the sweet, juicy kernels, and the pure joy of eating something straight from the grill make it a crowd-pleaser at barbecues, picnics, and casual dinners alike. But achieving that perfect balance of cooked-through tenderness and flavorful char requires more than just throwing corn on the grill. Understanding the nuances of grilling time, preparation methods, and heat control is key to unlocking the full potential of this seasonal favorite.
In-Husk vs. Naked: Choosing Your Grilling Style
There are two primary methods for grilling corn: in the husk and naked (husked). Each offers distinct advantages and requires different grilling times.
In-Husk Grilling: This method involves grilling the corn inside its natural husk. The husk acts as a protective barrier, steaming the corn and preventing it from drying out. This results in incredibly tender and juicy kernels. The slight char on the husk imparts a subtle smoky flavor.
Naked Grilling: This method involves removing the husk and silk completely before grilling. Naked grilling allows for direct contact with the heat, resulting in a more pronounced char and smoky flavor. However, it also requires careful monitoring to prevent the corn from drying out.
The Grilling Process: A Step-by-Step Guide
No matter which method you choose, following these steps will help you achieve perfectly grilled corn:
In-Husk Method:
- Soak the Corn: Submerge the corn (still in the husk) in cold water for at least 30 minutes, or up to 2 hours. This prevents the husks from burning and helps steam the corn from the inside.
- Prepare the Grill: Preheat your grill to medium heat (about 350-450°F).
- Grill the Corn: Place the soaked corn directly on the grill grates.
- Cook: Grill for 15-20 minutes, turning occasionally to ensure even cooking.
- Check for Doneness: The husks should be slightly charred, and the corn should feel tender when squeezed through the husk.
- Remove and Serve: Carefully remove the corn from the grill. Let it cool slightly before removing the husk and silk. Season with butter, salt, pepper, and any other desired toppings.
Naked Method:
- Prepare the Corn: Shuck the corn completely, removing the husk and silk.
- Brush with Oil: Lightly brush the corn with oil (olive oil or melted butter). This helps prevent sticking and enhances browning.
- Prepare the Grill: Preheat your grill to medium heat (about 350-450°F).
- Grill the Corn: Place the corn directly on the grill grates.
- Cook: Grill for 8-10 minutes, turning frequently to ensure even cooking and prevent burning.
- Check for Doneness: The kernels should be slightly charred and tender when pierced with a fork.
- Remove and Serve: Remove the corn from the grill. Season with butter, salt, pepper, and any other desired toppings.
Adjusting Grilling Time Based on Heat
The grilling time for corn can vary depending on the heat of your grill. If your grill runs hotter, you’ll need to reduce the grilling time to prevent burning. If your grill runs cooler, you’ll need to increase the grilling time to ensure the corn is cooked through. A good rule of thumb is to check the corn frequently and adjust the cooking time accordingly.
| Grill Temperature | In-Husk Grilling Time | Naked Grilling Time |
|---|---|---|
| High (450°F+) | 12-15 minutes | 6-8 minutes |
| Medium (350-450°F) | 15-20 minutes | 8-10 minutes |
| Low (Below 350°F) | 20-25 minutes | 10-12 minutes |
Common Mistakes to Avoid
Grilling corn seems simple, but a few common mistakes can ruin the experience:
- Overcooking: Overcooked corn becomes tough and dry. Keep a close eye on the corn and remove it from the grill as soon as it’s tender.
- Burning: Burning can occur if the grill is too hot or the corn is left unattended for too long. Turn the corn frequently and adjust the heat as needed.
- Not Soaking: Failing to soak the corn in the husk can lead to burnt husks and uneven cooking.
- Not Oiling Naked Corn: For naked corn, skipping the oil can result in dry kernels that stick to the grill.
- Ignoring Hot Spots: Be aware of hot spots on your grill and rotate the corn accordingly for even cooking.
Seasoning and Serving Suggestions
Grilled corn is delicious on its own, but a few simple seasonings can elevate it to the next level.
- Classic: Butter, salt, and pepper are a timeless combination.
- Mexican-Inspired: Elote seasoning (chili powder, lime juice, cotija cheese, cilantro) is a flavorful option.
- Garlic Herb: Garlic butter with chopped herbs like parsley, thyme, and chives adds a savory touch.
- Spicy: A sprinkle of cayenne pepper or a drizzle of hot sauce adds a kick.
Frequently Asked Questions (FAQs)
1. How do I know when the corn is done grilling in the husk?
The husks should be slightly charred and the corn should feel tender when squeezed through the husk. You can also carefully peel back a small section of the husk to check the kernels directly.
2. Can I grill frozen corn on the cob?
Yes, you can grill frozen corn. However, you may need to increase the grilling time by a few minutes to ensure it’s cooked through. Thawing slightly before grilling can also improve the texture.
3. What’s the best type of corn for grilling?
Fresh, sweet corn is the best choice. Look for corn with bright green husks and plump, milky kernels. Avoid corn with dry or brown husks.
4. Should I soak the corn even if I’m grilling it naked?
Soaking is not necessary for naked corn. However, some people prefer to soak it briefly to help prevent drying.
5. Can I use a gas grill or charcoal grill?
Yes, you can use either a gas or charcoal grill. The grilling time and method are the same for both. Charcoal grills often impart a smokier flavor.
6. What temperature should my grill be for grilling corn?
The ideal grill temperature is medium heat (about 350-450°F). This allows the corn to cook through without burning.
7. How do I prevent the corn from sticking to the grill?
Brushing the corn with oil before grilling will help prevent it from sticking. Make sure the grill grates are also clean.
8. Can I grill corn on an indoor grill pan?
Yes, you can grill corn on an indoor grill pan. The grilling time will be similar to the naked grilling method.
9. Is it better to grill corn with or without the silk?
If grilling in the husk, the silk can remain. If grilling naked, remove as much silk as possible.
10. What can I do with leftover grilled corn?
Leftover grilled corn can be used in salads, salsas, soups, or as a side dish. You can also cut the kernels off the cob and freeze them for later use.
11. Can I grill corn on the cob in foil?
Yes, wrapping corn in foil is another method. It essentially steams the corn and helps retain moisture. Add butter and seasonings before wrapping. Grilling time is similar to in-husk grilling.
12. How do I store grilled corn?
Store grilled corn in an airtight container in the refrigerator for up to 3 days. For best results, consume it as soon as possible.
