Overview of Cooking Corn in Foil
Cooking corn in foil on the grill is straightforward and enhances the natural sweetness and flavor. Wrapping corn helps retain moisture, preventing the kernels from drying out or burning.
Time and Temperature
Cook corn in foil for about 15 to 20 minutes over medium heat. The ideal grill temperature ranges between 350°F and 400°F. This range ensures the corn cooks evenly without becoming too soft or chewy.
Preparation Steps
- Select Fresh Corn: Choose ears with bright green husks and plump, moist kernels.
- Husk the Corn: Remove the outer leaves and silk, but you can leave some husks on for extra protection.
- Wrap the Corn: Place each ear on a square of aluminum foil, add a pat of butter, season with salt and pepper, and fold the foil tightly to create a pouch.
- Grill the Corn: Place the foil pouches on the grill, turning them occasionally for even cooking.
Checking for Doneness
To check if the corn is done, carefully unwrap one pouch. The kernels should be tender yet firm when pierced with a fork. If they need a little more time, rewrap and return them to the grill for a few extra minutes.





Flavor Variations
Experiment with different seasonings and toppings for added flavor. Try garlic powder, chili powder, or even cheese for a twist. Adding fresh herbs like cilantro or parsley after grilling can also enhance taste.
Safety Tips
Use tongs or gloves when handling hot foil pouches. Allow the corn to cool for a minute before unwrapping to avoid burns.
Following these guidelines ensures you enjoy perfectly grilled corn every time.
Benefits of Grilling Corn in Foil
Grilling corn in foil offers several advantages, making it a preferred method for many. Below are the main benefits of this technique.
Keeps the Corn Moist
Grilling corn in foil traps steam, ensuring that the kernels remain juicy. Wrapping each ear in aluminum foil creates a mini-steamer that prevents drying out. You’ll notice the texture stays tender, enhancing the overall eating experience. For best results, add a knob of butter before sealing the foil; it melts and infuses moisture throughout the corn.
Cooking Time for Corn in Foil
Cooking corn in foil on the grill requires precise timing to achieve the best results. Perfectly grilled corn maintains its moisture and flavor while allowing the natural sweetness to shine through.
Recommended Cooking Duration
Cook corn in foil for 15 to 20 minutes over medium heat, around 350°F to 400°F. For best results, turn the pouches every 5 minutes. This rotation ensures even cooking and prevents any kernels from sticking to the foil. Check for doneness by carefully unwrapping a pouch; kernels should be tender yet firm.





Factors Affecting Cooking Time
Several factors can influence the cooking time of corn in foil:
- Size of Corn: Larger ears may require additional time. Smaller ears can cook more quickly.
- Temperature of the Grill: A hotter grill can shorten cooking time. Ensure consistent heat for optimal results.
- Moisture Content: If adding liquid, such as butter or water, the added moisture may alter cooking time slightly.
- Foil Thickness: Thicker foil reflects heat differently, which can affect cooking duration.
Adjust cooking time as needed based on these factors to ensure perfectly grilled corn.
Best Practices for Grilling Corn in Foil
Grilling corn in foil enhances flavor and ensures moist kernels. Follow these best practices for delicious results every time.
Preparing the Corn
- Select Fresh Corn: Choose ears with bright green husks and plump kernels. Fresh corn delivers the best flavor.
- Husk the Corn: Remove the outer leaves and silk carefully. This ensures that seasoning penetrates the corn.
- Soak (Optional): Soaking corn for 30 minutes in water can add extra moisture. If you choose this method, be sure to dry the ears before wrapping.
- Season Generously: Spread butter, salt, and your favorite spices directly onto the kernels. You can add garlic powder, paprika, or fresh herbs for extra flair.
- Use Heavy-Duty Foil: Heavy-duty aluminum foil withstands heat well and prevents tearing. Prepare two layers if you’re using regular foil.
- Wrap Tightly: Wrap each ear securely, ensuring there’s no space for steam to escape. This traps moisture and helps cook the corn evenly.
- Create a Seal: Fold the edges of the foil tightly to avoid leaks. It’s crucial for retaining flavor and moisture.
- Add Flavorful Extras: Include slices of lemon or chili flakes in the foil for added zest. These small additions can elevate the taste significantly.
By following these best practices, you can enjoy perfectly grilled corn in foil that’s flavorful and moist, ideal for your next barbecue.
