How Long to Cook Corn on the Cob in the Oven Perfectly

Cooking corn on the cob in the oven is a simple way to enjoy sweet, juicy kernels without firing up the grill. Whether you’re short on time or the weather isn’t cooperating, oven roasting delivers delicious results with minimal effort.

Knowing the right cooking time is key to getting perfectly tender corn every time. Too short and it’s undercooked; too long and it can dry out. In this article, you’ll learn exactly how long to cook corn on the cob in the oven for that ideal balance of flavor and texture. You’ll be ready to serve up a tasty side dish that’s sure to impress.

How Long to Cook Corn on the Cob in the Oven

You cook corn on the cob in the oven at 350°F (175°C) for 30 to 35 minutes. Start by preheating the oven to 350°F. Wrap each ear of corn individually in aluminum foil to lock in moisture, which ensures tender kernels. Place the wrapped cobs directly on the oven rack or on a baking sheet for easier handling.

You can increase the temperature to 400°F (205°C) to reduce cooking time to about 25 to 30 minutes, but watch closely to avoid drying out the corn. Cooking times may vary slightly based on the size of the ears and whether they are fresh or partially dried.

You test for doneness by carefully unwrapping the foil and piercing a kernel with a fork; it should feel tender but firm. You can also brush the corn with butter or seasonings before wrapping to infuse extra flavor during roasting.

Oven Temperature	Cooking Time	Notes
350°F (175°C)	30 to 35 minutes	Standard cooking for tender results
400°F (205°C)	25 to 30 minutes	Faster cooking; monitor to prevent drying

Using this timing guide helps you achieve perfectly cooked corn on the cob in the oven without guesswork.

Preparing Corn for Oven Cooking

Proper preparation ensures your corn on the cob cooks evenly and stays juicy in the oven. Follow these steps to select and ready the corn before baking.

Choosing Fresh Corn on the Cob

Select ears with bright green husks that fit tightly around the corn. Avoid husks that appear dry or yellowed. Choose ears with moist, golden silk threads at the tip to guarantee freshness. Pick cobs heavy for their size, indicating plump kernels inside. Use corn within a day or two for the best flavor and texture.

Wrapping Corn for Oven Cooking

Remove loose outer husks but leave one or two inner layers to protect kernels during cooking. Wrap each ear tightly in aluminum foil to trap steam and moisture, which keeps the corn tender. Before wrapping, spread butter or seasonings on the kernels for extra taste. Seal the foil well to prevent steam from escaping and drying out the corn.

Cooking Times and Temperatures for Corn on the Cob

Cooking corn on the cob in the oven requires careful timing and temperature control to achieve tender, juicy kernels. Use the following guidelines based on whether you cook corn in the husk or without it.

Cooking Corn in the Husk

Cooking corn in the husk preserves moisture and enhances natural sweetness. Preheat your oven to 350°F (175°C). Place fresh ears with intact husks directly on the oven rack or a baking sheet. Cook for 30 to 35 minutes until the silks darken and kernels feel tender when pierced. Avoid higher temperatures to prevent drying out. Let the corn rest for a few minutes after removing from the oven to allow steam to finish cooking the kernels.

Cooking Corn Without the Husk

Cooking corn without the husk requires wrapping to retain moisture. Preheat your oven to 400°F (205°C). Remove all husks, then spread butter or seasoning on the kernels before wrapping each ear tightly in aluminum foil. Bake on a baking sheet for 25 to 30 minutes. The foil traps steam to keep the corn tender and juicy. Check doneness by carefully unwrapping and piercing a kernel with a fork; cook longer if kernels remain too firm.

Tips for Perfectly Cooked Oven Corn

Mastering oven-cooked corn on the cob requires attention to detail and simple techniques that guarantee tender, flavorful results. Use these tips to enhance your cooking process and corn quality.

Checking for Doneness

Test corn tenderness by piercing a kernel with a fork or toothpick. If it slides in easily and the kernels appear plump and juicy, the corn is done. Avoid overcooking, which causes kernels to dry out or become tough. Let the corn rest in foil for 5 minutes after removing it from the oven to allow residual steam to finish cooking the kernels evenly.

Adding Flavor Before and After Cooking

Boost flavor by spreading softened butter, olive oil, or herb mixtures directly on the kernels before wrapping the corn in foil. Sprinkle salt, pepper, garlic powder, or smoked paprika for extra seasoning. After cooking, brush corn with melted butter or drizzle with fresh lime juice for brightness. Garnish with chopped herbs like cilantro or parsley to enhance aroma and presentation.

Serving Suggestions for Oven-Cooked Corn on the Cob

Enhance your oven-cooked corn with flavorful toppings. Spread softened butter or olive oil evenly across the hot kernels. Season with salt, cracked black pepper, garlic powder, or smoked paprika for a robust taste.

Pair your corn with fresh herbs like chopped cilantro, parsley, or chives to add color and aroma. Squeeze fresh lime or lemon juice over the corn to introduce a bright, tangy contrast.

Serve your corn alongside grilled meats, salads, or roasted vegetables to complete a balanced meal. Cut the cooked ears into smaller sections for easy handling at picnics or barbecues. For a spicy kick, toss the corn with chili powder or a drizzle of hot sauce after cooking.

Conclusion

Cooking corn on the cob in the oven is a simple way to enjoy tender, flavorful corn anytime. By following the right temperature and timing, you’ll avoid dry or undercooked kernels. Wrapping the corn in foil locks in moisture and allows you to customize flavors with your favorite seasonings.

With a little practice, you’ll master the perfect oven-cooked corn that pairs well with any meal. Whether you’re prepping for a family dinner or a casual gathering, this method delivers consistently delicious results. So go ahead and enjoy sweet, juicy corn right from your oven!
