Grilling corn on the cob is a summertime staple, a ritual that evokes images of backyard barbecues and golden sunsets. But what if you’re not in a rush? What if you want to coax out every last drop of sweetness and moisture from those kernels? Can you grill corn on low heat? The answer is a resounding yes! In fact, grilling corn on low heat can unlock a level of flavor and tenderness that high-heat grilling often misses. This article will delve into the art and science of low-and-slow grilled corn, exploring the benefits, techniques, and secrets to achieving corn-on-the-cob perfection.
Why Choose Low Heat for Grilling Corn?
High-heat grilling definitely has its place. It’s quick, efficient, and can create a beautiful char. However, when it comes to corn, low heat offers several distinct advantages.
One of the primary benefits is even cooking. High heat can scorch the outside of the kernels before the inside is fully cooked. This can result in corn that is charred in spots but still starchy and undercooked in others. Low heat allows the heat to penetrate more gently, ensuring that each kernel is cooked evenly from the outside in.
Another significant advantage is enhanced moisture retention. Rapid heating can cause the moisture inside the corn to evaporate quickly, leading to dry, shriveled kernels. Low heat, on the other hand, allows the moisture to stay locked inside, resulting in juicy, plump, and incredibly flavorful corn.
Low-heat grilling also maximizes sweetness. The slower cooking process gives the natural sugars in the corn more time to caramelize, resulting in a richer, deeper, and more intensely sweet flavor.
Finally, low heat is more forgiving. With high heat, there’s a smaller margin for error. Overcooking can happen in a matter of minutes. Low heat allows for more flexibility and reduces the risk of burning, making it an ideal method for beginners or those who want a more relaxed grilling experience.
Mastering the Low-Heat Grilling Technique
Grilling corn on low heat requires a different approach than high-heat grilling. Here’s a step-by-step guide to help you achieve the perfect result.
Preparing the Corn
The first step is selecting the best corn. Look for ears that are heavy for their size, with tightly wrapped husks that are bright green. The silk protruding from the top should be golden and slightly sticky. Avoid ears with dry, brown, or withered silk.
Once you’ve selected your corn, you have a choice to make: grill it in the husk or shuck it first.
Grilling in the Husk: This method helps to steam the corn from the inside out, resulting in exceptionally moist and tender kernels. Simply soak the ears of corn in cold water for at least 30 minutes before grilling. This prevents the husks from burning too quickly.
Grilling Shucked: Shucking the corn allows for direct contact with the grill grates, resulting in a slightly charred and smoky flavor. If you choose to shuck the corn, remove the husks and silk completely. You can then wrap the corn in foil with a pat of butter and some seasonings, or grill it directly on the grates.
Setting Up Your Grill for Low Heat
Whether you’re using a gas grill or a charcoal grill, setting it up for low heat is crucial.
Gas Grill: For a gas grill, preheat it to the lowest setting, usually around 250-300°F (120-150°C). If your grill has multiple burners, you can turn off one or two of them to create an indirect heat zone. This will allow you to move the corn to a cooler area if it starts to brown too quickly.
Charcoal Grill: For a charcoal grill, arrange the coals on one side of the grill, creating a direct heat zone and an indirect heat zone. This allows you to control the heat and move the corn to the cooler side if needed. You can also use a smaller amount of charcoal than you would for high-heat grilling.
The Grilling Process
Whether you’re grilling in the husk or shucked, the grilling process is similar.
Grilling in the Husk: Place the soaked ears of corn directly on the grill grates over indirect heat. Close the lid and grill for 30-40 minutes, turning occasionally, until the husks are lightly charred and the corn is tender. To check for doneness, carefully peel back the husks and pierce a kernel with a fork. It should be tender and juicy.
Grilling Shucked: If you’re grilling shucked corn directly on the grates, brush the corn with olive oil or melted butter and season with salt and pepper. Place the corn on the grill grates over indirect heat and grill for 20-30 minutes, turning frequently, until the kernels are tender and lightly charred. If you’re grilling shucked corn in foil, simply wrap each ear in foil with butter and seasonings and grill over indirect heat for 20-30 minutes, turning occasionally.
Achieving the Perfect Char (Optional)
While low-heat grilling emphasizes tenderness and sweetness, some people still crave a bit of char. If you want to add some char to your low-heat grilled corn, you can do so by briefly moving the corn to the direct heat zone during the last few minutes of grilling. Just be sure to watch it closely to prevent burning.
Tips for Enhancing Flavor
While low-heat grilling naturally enhances the flavor of corn, there are several ways to take it to the next level.
Butter and Seasonings: Whether you’re grilling in the husk or shucked, butter and seasonings are essential. Before grilling, you can spread softened butter under the husks or brush it directly on the kernels. Experiment with different seasonings, such as salt, pepper, garlic powder, onion powder, chili powder, or smoked paprika.
Herb Infusions: Fresh herbs can add a burst of flavor to your grilled corn. Try adding sprigs of rosemary, thyme, or oregano under the husks or wrapping the corn in foil with fresh herbs.
Compound Butters: Elevate your grilled corn with compound butters. Mix softened butter with ingredients like roasted garlic, chili flakes, lime zest, or fresh herbs.
Cheese: A sprinkle of grated Parmesan cheese, cotija cheese, or feta cheese can add a salty and savory dimension to your grilled corn. Add the cheese during the last few minutes of grilling or after the corn is cooked.
Troubleshooting Common Issues
Even with the best techniques, grilling can sometimes present challenges. Here are some common issues and how to troubleshoot them.
Corn is not cooking evenly: This usually indicates that the heat is not distributed evenly. On a gas grill, try turning off one or two burners to create an indirect heat zone. On a charcoal grill, make sure the coals are arranged on one side of the grill.
Corn is burning: If the corn is burning, it means the heat is too high. Move the corn to a cooler part of the grill or reduce the heat setting. If grilling in the husk, make sure the husks are well-soaked.
Corn is dry: If the corn is dry, it could be due to overcooking or insufficient moisture. Make sure to grill the corn over low heat and avoid overcooking it. If grilling shucked corn, wrap it in foil with butter or soak it in water before grilling.
Corn is not sweet enough: The sweetness of corn depends on its freshness and the cooking process. Choose the freshest corn possible and grill it over low heat to allow the sugars to caramelize.

What type of corn is best for grilling low and slow?
Choosing the right corn variety is crucial for optimal results when grilling low and slow. Look for sweet corn varieties with plump kernels that feel firm to the touch. Avoid corn with dried-out husks or browning silks, as these are indicators of older, less flavorful corn. Fresh, locally sourced corn will generally provide the sweetest and most succulent experience.
Consider varieties like Silver Queen, Butter and Sugar, or Peaches and Cream, which are known for their high sugar content. These types will caramelize beautifully over low heat, resulting in a deep, sweet flavor. Remember to check the local farmers’ market or produce section for the freshest options available.
Should I soak the corn before grilling?
Soaking corn before grilling is a debated topic, but for low and slow grilling, it’s generally recommended. Soaking the corn, husk and all, for at least 30 minutes helps prevent the husks from burning too quickly during the extended cooking time. This allows the corn to steam slightly inside the husk, resulting in a more tender and juicy final product.
The water absorbed during soaking also helps to maintain moisture as the corn grills, preventing it from drying out over the low heat. While not strictly necessary, soaking contributes to a better overall texture and ensures a more forgiving grilling process, especially for beginners.
What temperature is considered “low and slow” for grilling corn?
“Low and slow” grilling for corn typically refers to maintaining a grill temperature between 225°F and 275°F (approximately 107°C to 135°C). This lower temperature allows the corn to cook gently and evenly, caramelizing the sugars without burning the husks or drying out the kernels. The extended cooking time draws out the natural sweetness of the corn, creating a richer, more complex flavor.
Maintaining this consistent low heat is key to achieving tender, juicy, and perfectly grilled corn. Use a reliable grill thermometer to monitor the temperature closely and adjust your grill’s vents or burner settings as needed to keep the temperature within the desired range.
How long should I grill the corn at a low and slow temperature?
Grilling corn low and slow generally requires a longer cooking time than high-heat grilling. Expect the corn to take approximately 45 minutes to 1 hour to cook through completely, depending on the size and freshness of the corn, as well as the specific temperature of your grill. The husks should be slightly charred and the kernels should be tender when pierced with a fork.
It is recommended to turn the corn occasionally, about every 15 minutes, to ensure even cooking on all sides. This helps to prevent scorching on any particular side and contributes to a more uniform caramelization. Remember that this extended time allows the natural sugars in the corn to develop, resulting in a deeply sweet and flavorful result.
How can I prevent the corn from drying out while grilling low and slow?
Preventing the corn from drying out during low and slow grilling is essential for achieving juicy perfection. Soaking the corn in water for at least 30 minutes prior to grilling, as mentioned earlier, helps retain moisture. Furthermore, consider adding a small amount of water to the bottom of the grill or smoker if using a charcoal grill.
Wrapping each ear of corn tightly in aluminum foil after soaking, before placing it on the grill, is also a great way to help retain the moisture and the steam that builds up inside the foil will help cook the kernels until soft. You can also use a spray bottle to lightly mist the husks with water every 20 minutes or so.
What are some flavor variations I can add while grilling the corn?
Grilling corn offers a blank canvas for experimenting with different flavor profiles. Before grilling, consider spreading softened butter mixed with herbs, spices, or garlic under the husks. This infuses the corn with flavor as it cooks, creating a delicious and aromatic experience.
After grilling, you can brush the corn with flavored oils, such as chili oil or truffle oil. Alternatively, try rolling the cooked corn in grated Parmesan cheese, crumbled cotija cheese, or a mixture of spices like chili powder, cumin, and lime zest. Don’t be afraid to get creative and explore different flavor combinations to find your perfect grilled corn creation.
How do I know when the corn is done?
Determining when corn on the cob is perfectly grilled requires a few key indicators. The husks should be slightly charred and easily peel back from the corn. When you peel back the husk, the kernels should appear bright yellow and plump.
To confirm doneness, gently pierce a kernel with a fork or knife. If it is tender and releases a milky liquid, the corn is ready. If it feels hard or starchy, it needs a bit more time on the grill. Remember that low and slow grilling ensures even cooking, so be patient and trust the process.
