The Easiest Grilled Corn on the Cob in Foil

Why Grill Corn in Foil?
Grilling corn in foil locks in moisture, ensuring each bite is tender and juicy. The foil protects the corn from direct flames, allowing it to cook evenly while absorbing all the delicious buttery flavors. Plus, it’s an easy cleanup, making it a go-to for any grill master.
Ingredients for Grilled Corn in Foil
- 6 ears corn, shucked
- 4 tablespoons softened butter
- ¼ teaspoon salt
- ½ teaspoon dried garlic powder (optional)
- ⅛ teaspoon ground black pepper (optional)
Optional Flavor Boosters
Feel free to get creative! Adding herbs like rosemary or thyme, or even a sprinkle of parmesan cheese, can elevate the flavor. If you’re in the mood for something spicy, consider a dash of cayenne pepper for a kick.
Step-by-Step Guide to Grilling Corn in Foil
Preparing the Corn and Butter
Start by preheating your grill to 400°F. While it’s heating, mash the softened butter with salt, garlic powder, and pepper until smooth. This mixture creates a rich, savory coating for your corn.
Assembling the Foil Packets
Take large pieces of aluminum foil and place two ears of corn on each. For added protection against tearing, use double-layer foil. Generously rub the butter mixture onto each ear, ensuring it’s well coated.
Grilling Your Corn
Fold the foil over the corn to create sealed packets, sealing in all that buttery goodness. Place the packets on the grill, close the lid, and let them cook for about 10 minutes.
Checking for Doneness and Finishing
After the first 10 minutes, carefully remove the packets and open them. Flip each ear of corn, reseal the packets, and return them to the grill for another 10 to 20 minutes. You’ll know it’s done when the corn is tender and slightly browned. Serve with additional butter and salt, if desired.
Tips for Perfect Grilled Corn Every Time
Adjusting Grill Time
Cooking times may vary based on your grill’s heat. Check for doneness after 18 minutes to ensure the corn doesn’t overcook.
Oven-Baked Alternative
If you’re not firing up the grill, you can still enjoy this dish! Preheat your oven to 400°F, place the foil packets on a baking sheet, and bake for 25-30 minutes, flipping halfway through. For a crispy finish, broil for 1-2 minutes after removing from the foil.
Preparing Corn Ahead of Time
You can prepare the corn and butter mixture ahead of time. Just store the prepared corn in the foil packets in the fridge for up to 4 hours. This makes it easy to throw on the grill when you’re ready to eat.
