Introduction to Oven-Roasted Corn on the Cob
Few side dishes capture the taste of summer like corn on the cob. While grilling may be the traditional go-to, roasting corn in the oven creates equally mouthwatering results — without having to stand outside over a hot flame.
The dry heat of the oven caramelizes the natural sugars in corn, producing tender kernels with a light char and a deeper, more concentrated flavor.
Another bonus? This method works beautifully year-round. Whether you’re enjoying fresh, just-picked summer corn or making the most of frozen corn during the colder months, oven roasting brings out its sweetness and gives you the perfect bite every time.

Selecting fresh summer corn
Nothing beats the taste of in-season corn.
Look for ears with bright green husks that fit snugly around the kernels. The silk at the top should be golden and slightly sticky, not dried out.
Gently peel back the husk to check for plump, tightly packed kernels — they should release a milky liquid when pierced.
Using frozen corn on the cob when fresh isn’t available
Frozen corn can be just as sweet and juicy if cooked properly. Thaw it in the fridge overnight or run it under cold water before roasting. Avoid microwaving to thaw, as this can cause uneven cooking.
Ingredients You’ll Need
Classic seasoning for oven-roasted corn
- Fresh corn on the cob (husked)
- Unsalted butter or olive oil
- Sea salt
- Freshly ground black pepper
Creative flavor combinations to try
- Garlic-herb butter: butter, minced garlic, parsley, thyme
- Smoky paprika blend: olive oil, smoked paprika, cayenne pepper

Step-by-Step Instructions for Perfect Roasted Corn
Prepping the corn for the oven
- Preheat oven to 425°F (220°C).
- Husk the corn completely and remove any lingering silk.
- Pat corn dry with a clean towel — this helps the butter or oil cling better and promotes browning.
Roasting times and temperature tips
- Brush each ear of corn with melted butter or olive oil, then season generously with salt and pepper.
- Arrange on a baking sheet, leaving space between each ear for even cooking.
- Roast for 20–25 minutes, turning halfway, until kernels are tender and lightly browned.
Finishing with butter and seasonings
Once out of the oven, brush with more butter or oil, sprinkle with your favorite seasonings, and serve immediately for the juiciest bite.
Expert Tips for Best Results
How to get lightly charred, caramelized kernels
For more browning, move the baking sheet to the top rack for the last 3–4 minutes and turn on the broiler. Keep a close eye to avoid burning.
Avoiding soggy corn
Dry the corn thoroughly before seasoning, and avoid wrapping in foil unless you prefer a softer, steamed texture.

FAQs about Oven-Roasted Corn on the Cob
Can you roast corn without husks?
Yes — in fact, removing the husks helps the kernels caramelize better.
How do you know when corn is fully cooked?
Kernels will be tender, slightly plump, and lightly browned in spots.
Can I roast corn with the husks on?
Yes, but it will steam inside the husk rather than roast. This results in a softer texture.

Not necessary — direct roasting gives a deeper flavor.
Can I make this recipe dairy-free?
