Oven-roasted corn on the cob pairs well with a wide range of main dishes and can be prepared in large batches for gatherings. Its versatility and ease of preparation make it an excellent choice for both weeknight meals and special occasions. With just a few basic ingredients and about 30 minutes of cooking time, you can serve up perfectly roasted corn that rivals any grilled version.

Selecting and Preparing Fresh Corn for Roasting
Fresh corn selection and proper preparation are crucial for achieving delicious oven-roasted corn on the cob. Choosing quality ears and removing husks and silk effectively will ensure the best flavor and texture.
Choosing the Best Corn
Look for corn with bright green, tightly wrapped husks. The silk at the top should be light brown or golden, and slightly sticky to the touch. Avoid ears with dry or dark brown silk.
Feel the kernels through the husk – they should be plump and firm. Squeeze gently to check for even kernel distribution without gaps.
Choose ears that feel heavy for their size, indicating juiciness. Fresh corn should have a slightly sweet aroma at the stem end.
For optimal sweetness, select corn at its peak ripeness during summer months. Aim to cook corn within 1-2 days of purchase for best flavor.
Cleaning and Husking Tips
Start by peeling back the outer layers of husk, leaving a thin layer attached. This helps protect kernels during roasting while allowing for caramelization.
Remove visible silk strands by hand. For stubborn silk, use a soft brush or damp paper towel to gently rub the kernels.
Trim any brown edges from the husk at the top of the ear. Cut off about 1 inch from the stem end to remove tough fibers.
If roasting without husks, remove them completely along with all silk. Rinse the corn under cool water and pat dry before seasoning.
For easier handling, cut larger ears in half before roasting. This also allows for more even cooking and caramelization.
Oven-Roasting Techniques
Oven-roasting corn offers versatile methods to achieve delicious results. The key techniques include roasting with husks on or off, and using aluminum foil for even cooking.
Roasting with Husks On
Roasting corn with husks on preserves moisture and enhances flavor. Preheat the oven to 350°F (175°C). Trim excess silk from the top of each ear. Place the corn directly on the oven rack or on a baking sheet.
Roast for 30-35 minutes, turning once halfway through. The husks will brown and may char slightly. This method steams the corn inside its natural wrapper, resulting in tender, juicy kernels.
After cooking, let the corn cool for 5 minutes before removing the husks. The silk will come off easily with the husk.
Roasting with Husks Off
For a more caramelized flavor, roast corn with husks removed. Preheat the oven to 400°F (200°C). Remove husks and silk from each ear. Place corn on a baking sheet lined with parchment paper.
Brush each ear with melted butter and season with salt and pepper. Roast for 20-25 minutes, turning every 5-7 minutes for even browning. This method produces corn with a slightly crispier texture and more pronounced roasted flavor.
Keep an eye on the corn to prevent over-browning. The kernels should be plump and golden when done.
Using Aluminum Foil for Even Cooking
Wrapping corn in aluminum foil ensures even cooking and allows for easy seasoning. Preheat the oven to 425°F (220°C). Remove husks and silk from each ear. Place each ear on a piece of foil.
Brush corn with butter and sprinkle with desired seasonings. Wrap tightly in foil, twisting the ends to seal. Place on a baking sheet and roast for 20-25 minutes.
This method traps steam, resulting in tender kernels. It also allows for customized seasoning blends for each ear. For a charred effect, open the foil for the last 5 minutes of cooking.
Cooking Times and Temperatures
Oven-roasted corn on the cob typically requires temperatures between 350°F and 425°F (175°C to 218°C). The optimal temperature depends on the desired outcome and cooking method.
For corn roasted in its husks, set the oven to 350°F (175°C). This method takes about 30-40 minutes. The husks protect the kernels, allowing them to steam gently.
Shucked corn benefits from higher temperatures. Preheat the oven to 400°F-425°F (200°C-218°C). Cooking time ranges from 20-30 minutes, depending on the corn’s size and desired level of caramelization.
When wrapping corn in foil, a temperature of 400°F (200°C) works well. The foil-wrapped cobs need approximately 20-25 minutes to cook through.
Here’s a quick reference table:
| Method | Temperature | Cooking Time |
|---|---|---|
| In husks | 350°F (175°C) | 30-40 minutes |
| Shucked | 400°F-425°F (200°C-218°C) | 20-30 minutes |
| Foil-wrapped | 400°F (200°C) | 20-25 minutes |
For all methods, turn the corn halfway through cooking for even roasting. The corn is ready when the kernels are tender and easily pierced with a fork.
