Here is a simple and effective way to cook corn on the cob in the oven:

1. Preheat your oven to 425°F (220°C).
2. Remove husks and silk from the corn.
3. Rub each ear of corn evenly with softened butter or olive oil.
4. Season with salt and pepper (and other seasonings if desired).
5. Wrap each ear of corn tightly in aluminum foil.
6. Place wrapped corn on a baking sheet.
7. Bake for about 20 to 30 minutes, turning the corn halfway through cooking.
8. Remove from the oven, unwrap, and optionally brush with more butter before serving.

This method yields tender, juicy, and flavorful corn. You can also experiment with different seasonings like garlic powder, Cajun seasoning, cayenne pepper, or fresh herbs for variety. If you prefer cooking corn in the husk, you can roast unshucked corn at 350°F for about 30 minutes, then let it cool slightly before peeling off the husks and silks. Both methods are easy and convenient for oven roasting corn on the cob.
