How to roast corn in the oven when you don't have a grill?

Oven-roasted corn with caramelized flavor

Roasting in the oven is a reliable way to get caramelized kernels without a grill. It’s great when you need to roast several ears at once or during inclement weather.

Method:

  1. Preheat to 425°F (220°C).
  2. Remove husks and silks, brush ears lightly with oil or melted butter, and season with salt.
  3. Arrange on a rimmed baking sheet with space between ears. Roast for 20–30 minutes, turning once halfway, until kernels start to brown and blister.

For a charred finish: after roasting, place under the broiler for 1–2 minutes per side to add spots of deep char—watch closely to avoid burning.

Flavor variations:

  • Herb-roast: toss with rosemary, thyme, or garlic before roasting.
  • Sweet-savory: brush with honey-butter during the last 5 minutes.
  • Spicy: sprinkle smoked paprika or cayenne right after roasting.

Advantages and tips:

  • Oven roasting is hands-off and consistent for multiple ears.
  • Use a wire rack on the sheet pan for more even heat circulation and better blistering.
  • If you prefer a softer texture, wrap ears in foil with butter and roast 25–30 minutes.

Avoid overcrowding the pan, which steams instead of roasts, reducing caramelization.
