The sweet, smoky flavor of grilled sweet corn is a staple of summer barbecues and outdoor gatherings. But how long to cook sweet corn on the grill is a question that has puzzled many a grill master. The answer, it turns out, is not as simple as it seems. In this article, we’ll delve into the world of grilled sweet corn and explore the factors that affect cooking time, as well as provide some expert tips for achieving perfectly cooked, deliciously charred sweet corn every time.
Understanding Sweet Corn
Before we dive into the nitty-gritty of cooking times, it’s essential to understand the anatomy of sweet corn. Sweet corn is a type of corn that is high in moisture content, which makes it perfect for grilling. The kernels are tender and sweet, with a high sugar content that caramelizes beautifully when exposed to heat.
There are several types of sweet corn, including yellow, white, and bi-colored. Each type has its own unique characteristics, but they all share the same basic structure: a tough outer husk, a fibrous cob, and tender kernels.
Factors Affecting Cooking Time
So, how long to cook sweet corn on the grill? The answer depends on several factors, including:
- Heat: The temperature of your grill plays a significant role in cooking time. Higher heat will cook the corn faster, but it also increases the risk of burning.
- Moisture: Sweet corn is high in moisture, which affects cooking time. If the corn is too wet, it will steam instead of grill, resulting in a mushy texture.
- Thickness: The thickness of the corn husks and the size of the ears also impact cooking time. Thicker husks and larger ears take longer to cook.
- Grill type: The type of grill you use can also affect cooking time. Gas grills cook faster than charcoal grills, while ceramic grills cook more evenly.
Grill Temperature and Cooking Time
Here’s a general guideline for cooking sweet corn on the grill, based on temperature:
| Temperature | Cooking Time |
| — | — |
| Medium heat (300°F – 350°F) | 10-15 minutes |
| Medium-high heat (350°F – 400°F) | 5-10 minutes |
| High heat (400°F – 450°F) | 3-5 minutes |
Keep in mind that these are general guidelines, and cooking time may vary depending on the specific conditions of your grill.
Preparation is Key
Before you throw your sweet corn on the grill, it’s essential to prepare it properly. Here are some tips to ensure your corn is grilled to perfection:

What is the best way to prepare sweet corn for grilling?
To prepare sweet corn for grilling, start by husking the corn and removing the silk. You can also soak the corn in water for about 30 minutes to help keep it moist during the grilling process. This step is optional but recommended, especially if you’re using older corn. After soaking, pat the corn dry with a paper towel to remove excess moisture.
You can also add flavor to your sweet corn by brushing it with oil, butter, or a marinade before grilling. Some popular seasonings for grilled sweet corn include salt, pepper, garlic powder, and paprika. You can also try using herbs like thyme or rosemary for a more unique flavor. Experiment with different combinations to find the one you like best.
How long does it take to grill sweet corn?
The grilling time for sweet corn will depend on the heat of your grill and the desired level of doneness. Generally, it takes about 10-15 minutes to grill sweet corn over medium heat. You can rotate the corn every 2-3 minutes to ensure even cooking. If you prefer your corn more charred, you can grill it for an additional 2-3 minutes.
It’s also important to check the corn for doneness by inserting a fork or knife into one of the kernels. If it slides in easily, the corn is cooked. You can also check for visual cues like a slightly charred exterior and a tender interior. Keep in mind that overcooking can make the corn tough and dry, so aim for a slightly tender texture.
Can I grill sweet corn in the husk?
Yes, you can grill sweet corn in the husk, and it’s actually a popular method. To do this, soak the corn in water for about 30 minutes, then place it on the grill over medium heat. Close the grill lid and cook for about 15-20 minutes, or until the husk is charred and the corn is tender.
Grilling in the husk helps to retain moisture and adds a smoky flavor to the corn. To serve, simply peel back the husk and slather with butter or your favorite toppings. Keep in mind that grilling in the husk can make the corn more difficult to rotate, so you may need to adjust the cooking time accordingly.
How do I prevent sweet corn from burning on the grill?
To prevent sweet corn from burning on the grill, make sure to rotate it frequently. You can also adjust the heat to a lower setting if you notice the corn is browning too quickly. Additionally, you can brush the corn with oil or butter to help create a barrier against the heat.
Another tip is to grill the corn over indirect heat, which means placing it on the cooler side of the grill. This will help to cook the corn more slowly and prevent burning. You can also use a grill mat or foil to protect the corn from direct heat.
Can I grill frozen sweet corn?
Yes, you can grill frozen sweet corn, but it’s best to thaw it first. To thaw frozen corn, simply leave it in room temperature for a few hours or thaw it in the microwave according to the package instructions. Once thawed, pat the corn dry with a paper towel to remove excess moisture.
Grilled frozen corn can be just as delicious as fresh corn, but it may not have the same texture. To achieve the best results, make sure to cook the corn over medium heat and rotate it frequently. You can also add flavorings like butter, salt, and pepper to enhance the taste.
How do I store leftover grilled sweet corn?
To store leftover grilled sweet corn, let it cool to room temperature first. Then, wrap it tightly in plastic wrap or aluminum foil and refrigerate for up to 3 days. You can also freeze grilled corn for up to 3 months. To freeze, place the corn in an airtight container or freezer bag and store in the freezer.
When reheating leftover grilled corn, you can simply microwave it for a few seconds or grill it again over low heat. You can also add it to salads, soups, or other dishes for a burst of flavor and texture. Keep in mind that leftover corn may not be as tender as freshly grilled corn, but it can still be delicious.
Can I grill sweet corn at a low temperature?
Yes, you can grill sweet corn at a low temperature, and it’s actually a great way to cook it. Grilling over low heat helps to cook the corn more slowly and prevents burning. To grill at a low temperature, place the corn on the cooler side of the grill and close the lid.
Low-heat grilling is perfect for those who prefer a more tender and slightly sweet corn. It’s also a great way to cook corn for a crowd, as it allows you to cook multiple ears at once. Simply rotate the corn every 5-7 minutes to ensure even cooking, and adjust the cooking time as needed.
