Oven roasted corn on the cob is sweet, juicy, and golden with the most delicious caramelized edges!

No grill? No problem! The oven does all the work here and delivers that yummy roasted flavor with zero grilling skills required. Just brush the fresh corn with olive oil, season it with some spices, and roast at 425°F until the kernels are tender and lightly charred in spots.

When it’s done, brush the whole thing with melted butter right out of the oven. That hot corn soaks up every bit of butter and it is absolutely yummy.

This works as an easy weeknight side dish or a summer cookout staple when the grill is already full. Plus cleanup is a breeze with a foil-lined pan! Try flavored butters like garlic, chili-lime, or honey butter for a fun twist that takes this over the top.

Ingredient Notes

Fresh Corn – Use fresh corn for this. The fresher the better! Look for bright green husks and plump kernels. Check the tops by peeling the husks back slightly before buying.

Olive Oil – Coats the corn for roasting. Try flavored olive oil like garlic or sesame for extra flavor.

Spices – I like to use smoked paprika for some color and flavor, chili powder for a little kick, and some garlic powder because it adds another layer of flavor. Use your favor combination of spices!

Butter – I use salted butter for this to add some extra flavor. Melted and brushed on hot corn right out of the oven. Try garlic butter, chili-lime butter, or honey butter for a fun twist!

Fresh Herbs – Chopped parsley or cilantro for garnish. Optional but makes the corn so pretty.

Frequently Asked Questions

Can I use frozen corn on the cob?

Fresh corn works best for roasting. Frozen corn on the cob can be watery when thawed and won’t caramelize as well.

Do I need to soak the corn first?

No soaking needed! Just peel, season, and roast.

Can I use a toaster oven?

Yes! A toaster oven works perfectly. Use convection mode if available for crispier results.

How do I know when the corn is done?

Kernels should be tender and have lightly charred spots after 25-30 minutes. Turn halfway through for even roasting.

Can I add the butter before roasting?

I recommend olive oil before roasting and butter after. Butter can burn at 425°F if you’re not careful.

What flavored butters work well with corn?

Garlic butter, chili-lime butter, honey butter, and herb butter all work great!

Can I roast the corn in the husk?

You can but it steams more than roasts. Removing husks gives you that caramelized roasted flavor.
