Grilling corn on the cob in tin foil is a classic summer cooking technique that yields deliciously tender and flavorful results. This method combines the smoky essence of grilling with the gentle steaming effect of the foil packet, ensuring perfectly cooked kernels every time.
To grill corn in foil, simply shuck the ears, rub them with olive oil, sprinkle with salt and pepper, and add a few pats of butter before wrapping tightly in aluminum foil. Place the foil-wrapped corn on a preheated grill and cook for 16-20 minutes, flipping halfway through. The foil protects the corn from direct heat while allowing it to cook evenly and retain moisture.
This foolproof technique is ideal for both novice and experienced grillers alike. It offers flexibility in seasoning options and can be easily adapted to accommodate various flavor preferences. Whether hosting a backyard barbecue or preparing a weeknight dinner, grilled corn in foil is a simple yet impressive side dish that complements a wide range of grilled main courses.
Selecting Fresh Corn
Choosing the right corn is crucial for a delicious grilled dish. Look for ears with bright green, tightly wrapped husks. These indicate freshness and proper moisture retention.
Feel the kernels through the husk. They should be plump and tightly packed. Avoid ears with gaps between rows or shriveled kernels.
Check the tassel (silk) at the top of the ear. Fresh corn has light golden or brown silks that are slightly sticky. Avoid dark or dry tassels, which signal older corn.
Peel back a small section of the husk to examine the kernels. They should be plump and shiny. Colors can vary from pale yellow to dark golden.
For optimal flavor, choose corn that’s in season and locally grown when possible. Fresh-picked corn tastes sweetest.
Store corn in the refrigerator with husks intact until ready to grill. Use within 1-2 days for best results.
Remember, fresher corn requires less cooking time on the grill. This helps preserve its natural sweetness and texture.
Preparing the Grill
Proper grill preparation is crucial for achieving perfectly grilled corn on the cob. A clean, preheated grill ensures even cooking and prevents sticking.
Preheat the Grill
Set your grill to medium-high heat, aiming for a temperature between 375°F and 425°F. For gas grills, turn on all burners and close the lid. Allow 10-15 minutes for the grill to reach the desired temperature.
Charcoal grill users should light the coals and wait until they’re covered with gray ash. Spread them evenly across the bottom of the grill. Close the lid and let the grate heat up for 5-10 minutes.
A properly preheated grill creates those desirable char marks on the corn and ensures even cooking throughout the kernels.
Cleaning and Oil the Grates
While the grill preheats, clean the grates thoroughly. Use a stiff wire brush to remove any leftover food particles or debris from previous grilling sessions.
After cleaning, lightly oil the grates to prevent the corn from sticking. Dip a folded paper towel in vegetable oil and use tongs to rub it across the grates.
This oiling step is especially important when grilling corn directly on the grates without foil. It helps create a non-stick surface and contributes to those appealing grill marks.
Wrapping Corn in Foil
Properly wrapping corn in foil is crucial for achieving perfectly grilled corn on the cob. This process involves selecting the right foil, seasoning the corn, and constructing well-sealed foil packets.
Choosing the Right Foil
Heavy-duty aluminum foil is ideal for grilling corn. It withstands high heat and prevents tearing during cooking. Use sheets approximately 12 inches long for each ear of corn. This size provides ample coverage and allows for easy sealing.
Regular aluminum foil can work in a pinch, but it may require double-wrapping to ensure durability. Non-stick foil is another option that prevents the corn from sticking and makes cleanup easier.
Seasoning the Corn
Before wrapping, season the corn generously. Brush each ear with melted butter or olive oil. This step helps the seasonings adhere and enhances flavor.
Sprinkle salt over the corn. For added flavor, try paprika, Old Bay seasoning, or smoked paprika. Ranch seasoning offers a tangy twist. Compound butter, made by mixing softened butter with herbs or spices, can be spread on the corn for extra richness.
Apply seasonings evenly to ensure consistent flavor throughout the corn.
Foil Packet Construction
Place the seasoned corn in the center of the foil sheet. Bring the long sides of the foil up and over the corn, folding them together to create a seal. Leave some space around the corn for steam to circulate.
Fold the short ends of the foil inward, creating a tight seal on each end. Crimp these edges to prevent any butter or seasoning from leaking out during grilling.
For extra protection against leaks or tears, consider double-wrapping the corn. This method is especially useful when using thinner foil or cooking over very high heat.
Grilling Techniques
Grilling corn on the cob in foil is a simple and effective method. Start by preheating the grill to medium-high heat, around 350-400°F.
Prepare the corn by removing the husks and silk. Place each ear on a piece of foil large enough to wrap it completely.
Brush each ear with melted butter and sprinkle with salt. For added flavor, herbs or spices can be included at this stage.
Wrap the corn tightly in the foil, ensuring all edges are sealed to prevent butter from leaking out.
Place the foil-wrapped corn on the preheated grill. Cook for 15-20 minutes, turning every 5 minutes to ensure even cooking.
For a charred flavor, unwrap the corn for the last few minutes of cooking and place directly on the grill grates.
To test for doneness, carefully squeeze the corn through the foil. It should feel tender when ready.
Let the corn rest in the foil for 5 minutes after removing from the grill. This allows for further steaming and ensures juicy results.
Unwrap carefully and serve hot. Grilled corn pairs well with additional butter, salt, or other toppings of choice.
Cooking Times and Temperatures
Grilling corn on the cob in foil typically takes 15-20 minutes. The ideal grill temperature is medium-high heat, around 375-400°F (190-204°C).
Place the foil-wrapped corn on the preheated grill grates. Turn the corn every 5 minutes to ensure even cooking.
For softer kernels, grill for 15 minutes. For a slightly charred flavor, extend the cooking time to 20 minutes.
Cooking times may vary based on the size and freshness of the corn. Larger or older ears may require a few extra minutes.
A simple test for doneness: Carefully squeeze the corn through the foil. If it feels tender, it’s ready to eat.
Avoid grilling corn for more than 25 minutes, as it can become overcooked and mushy.
| Corn Texture | Grilling Time |
|---|---|
| Soft | 15 minutes |
| Firm | 20 minutes |
For those without a grill, microwaving is an alternative method. Microwave corn on high for 3-4 minutes per ear, adding 1 minute for each additional ear.
Remember to let the corn cool for a few minutes after grilling before unwrapping the foil to avoid steam burns.
