How Long to Grill Corn on the Cob in Foil?

Grilling corn on the cob in foil is one of the best ways to achieve juicy, flavorful kernels with minimal effort. This method locks in moisture, prevents burning, and allows you to infuse the corn with delicious seasonings. Whether you’re grilling for a backyard BBQ or a simple family dinner, wrapping corn in foil ensures even cooking and incredible taste.

The key question most people ask is, how long does it take to grill corn on the cob in foil? The answer depends on your grill’s temperature and whether you’re using direct or indirect heat. In this guide, we’ll break down the exact cooking time and share tips to make your grilled corn perfect every time.

Preparing the Corn for Grilling

Before placing the corn on the grill, it’s important to prepare it properly. Follow these steps to get your corn ready for grilling:

1. Husk or No Husk?

You have two options:

• Remove the husk completely: This allows for better seasoning and even grilling.
• Leave the husk on: Some people prefer to keep the husk on to provide natural steam, but when using foil, husk removal is the better choice.

2. Clean and Soak the Corn (Optional)

• Remove the silk strands after husking.
• If desired, soak the corn in water for 15-20 minutes to add moisture, preventing dryness during grilling.

3. Seasoning the Corn

This is where you can get creative! Before wrapping the corn in foil, add seasonings such as:

• Butter or olive oil – helps keep the corn moist.
• Salt and pepper – enhances natural sweetness.
• Garlic powder, smoked paprika, or chili powder – adds a flavor boost.
• Fresh herbs like parsley or cilantro – pairs well with butter.
• Grated parmesan or cotija cheese – for a cheesy crust.

4. Wrapping the Corn in Foil

• Tear off a piece of aluminum foil large enough to wrap the corn fully.
• Place the seasoned corn in the center and wrap it tightly, ensuring no gaps.
• If grilling multiple cobs, wrap them individually for even cooking.

Grilling Time and Temperature

The grilling time depends on whether you use direct heat or indirect heat.

1. Grilling Over Direct Heat (Faster Method)

• Temperature: 375–400°F (Medium-High Heat)
• Cooking Time: 15-20 minutes
• Instructions:
  • Place foil-wrapped corn directly on the grill grates.
  • Rotate every 5 minutes for even cooking.
  • Check for doneness by carefully opening the foil and piercing a kernel with a fork. It should be tender.

2. Grilling Over Indirect Heat (Slower, Even Cooking)

• Temperature: 350°F (Medium Heat)
• Cooking Time: 25-30 minutes
• Instructions:
  • Place foil-wrapped corn on the grill but away from the direct flame.
  • Turn occasionally to ensure even cooking.
  • After 25 minutes, check the kernels for tenderness.

How to Tell If Corn Is Done

• The kernels should be plump and tender when poked with a fork.
• The foil may have slight steam buildup inside, indicating moisture retention.
• You can also remove the foil and let the corn grill for 2-3 minutes for a slight char.

Tips for the Best Grilled Corn

1. Add Extra Butter Before Wrapping

For ultra-juicy corn, slather each cob with butter before sealing it in foil.

2. Experiment With Different Seasonings

Try flavored butters like garlic butter, honey butter, or herb-infused butter.

3. Use Heavy-Duty Foil

Regular foil works, but heavy-duty foil prevents tearing and ensures better heat distribution.

4. Let Corn Rest After Grilling

Once removed from the grill, let the foil-wrapped corn sit for 5 minutes to allow juices to redistribute.

5. Try Grilling Without Foil

If you like charred, smoky flavor, grill corn directly over flames for 2-3 minutes after removing the foil.

Serving Suggestions

Grilled corn is a versatile side dish that pairs well with many meals. Here are some delicious serving ideas:

1. Classic Buttered Corn

• Brush with melted butter and sprinkle with salt and pepper.

2. Mexican Street Corn (Elote)

• Top with mayo, cotija cheese, chili powder, and lime juice for a bold flavor.

3. Herb and Garlic Corn

• Mix butter, minced garlic, and chopped herbs for an aromatic side dish.

4. Parmesan and Lemon Corn

• Sprinkle with grated parmesan, lemon zest, and a pinch of salt for a tangy, cheesy twist.

5. BBQ-Spiced Corn

• Coat with BBQ seasoning or smoked paprika for a smoky flavor profile.

Conclusion

Grilling corn on the cob in foil is an easy and foolproof method that guarantees tender, juicy, and flavorful corn every time. Depending on your grilling technique, it takes about 15-20 minutes over direct heat or 25-30 minutes over indirect heat at medium-high temperatures.

By experimenting with different seasonings, butter infusions, and serving styles, you can create a delicious grilled corn dish that complements any meal. Whether you enjoy it simply buttered or dressed up with cheese and spices, grilled corn is always a crowd-pleaser at summer BBQs and family cookouts.

So fire up the grill, wrap your corn in foil, and enjoy the perfect balance of sweetness and smoky flavor! Happy grilling.
