How to Cook an Ear of Corn in the Oven: Easy, Delicious Oven-Roasted Corn Recipe

There’s something incredibly satisfying about biting into a perfectly cooked ear of corn. While grilling gets all the attention, cooking corn in the oven is a simple, foolproof method that delivers sweet, tender kernels every time. I’ve found that oven-roasting brings out the natural flavors without the hassle of outdoor cooking.

Why Cook Corn in the Oven?

Cooking corn in the oven offers consistent heat that ensures even cooking, which prevents hot spots common with grilling. I find it delivers tender kernels and a slightly caramelized sweetness without needing constant attention. Oven cooking eliminates worries about weather or having a grill ready, making it a reliable option year-round.

Using the oven locks in moisture, reducing the risk of drying out the corn, especially when wrapped in foil or husks. I appreciate that this method requires minimal preparation and clean-up, as there’s no charcoal or grill racks to manage. It also allows for easy seasoning before cooking, so flavors penetrate deeply during the roasting process.

This process requires less hands-on time, freeing me up to prepare other dishes or relax. Lastly, the oven method adapts well to different batch sizes, whether roasting a single ear or multiple ears simultaneously with consistent results.

Preparing the Corn for Baking

Preparing the corn properly lays the foundation for perfectly baked ears with full flavor and texture. I focus on selecting the best ears and removing unwanted parts efficiently.

Choosing Fresh Ears of Corn

I always pick ears with bright green husks that wrap tightly around the rows of kernels. Avoid ears with dry or yellowing husks, as these indicate older corn. I look for plump, evenly spaced kernels that feel firm to the touch. Ears with slightly golden silk at the top suggest freshness. Fresh corn ensures sweetness and tenderness after baking.

Removing Husks and Silk

I remove husks by pulling them down gently but completely, exposing all kernels. After husking, I carefully pick off the remaining silks using my fingers or a soft brush. Ensuring the ear is free of silk prevents chewy bits in the final dish. If preferred, I sometimes leave the husks on for baking to lock in moisture, peeling them back just enough to season the kernels.

Step-by-Step Guide to Cooking Corn in the Oven

Cooking corn in the oven requires just a few straightforward steps. Following this guide ensures tender, flavorful ears with a natural sweetness.

Preheating the Oven

I set the oven to 400°F (204°C) for optimal roasting. This temperature balances thorough cooking and gentle caramelization. Preheating guarantees the oven reaches a consistent heat before placing the corn inside.

Wrapping the Corn for Baking

I wrap each ear in aluminum foil to lock in moisture. Wrapping prevents the kernels from drying out while allowing them to steam in their natural juices. Alternatively, leaving the husks on achieves a similar effect by trapping moisture, but foil provides a tighter seal. For seasoning, I unwrap the foil after baking or lightly brush butter and spices before sealing.

Baking Time and Temperature

I bake the wrapped corn at 400°F (204°C) for 25 to 30 minutes. Larger or multiple ears may extend cooking time by 5 to 10 minutes. The corn is done when the kernels look plump and slightly caramelized. For a charred finish, I broil the corn for 2 to 3 minutes after baking, watching closely to avoid burning.

Tips for Adding Flavor and Seasoning

Enhancing oven-cooked corn with flavor starts with choosing the right seasoning. I apply butter or olive oil evenly over each ear before wrapping it in foil. Adding salt and freshly ground black pepper improves the natural sweetness of the kernels. For a spicy kick, I sprinkle chili powder, cayenne pepper, or smoked paprika.

Herbs like chopped cilantro, parsley, or thyme complement roasted corn well. I often mix minced garlic with softened butter, spreading it under the husks or inside the foil for more depth. Citrus zest, such as lime or lemon, brightens the flavor and balances richness.

Cheese options also pair nicely: grated Parmesan or crumbled Cotija add a salty tang. If I want a smoky flavor, I use smoked salt or a dash of liquid smoke sparingly. Applying these seasonings before baking lets the flavors meld with the corn’s natural juices during roasting.

For a finishing touch, I brush with extra melted butter or sprinkle more herbs immediately after removing the corn from the oven. This preserves freshness and ensures each bite bursts with flavor.

Serving Suggestions for Oven-Baked Corn

I serve oven-baked corn with a variety of complementary dishes to highlight its natural sweetness and roasted flavor. I often pair it with grilled meats like chicken, steak, or pork chops for a balanced meal. For a vegetarian option, I combine the corn with a fresh salad featuring tomatoes, avocado, and a tangy vinaigrette.

I recommend topping the corn with flavored butters, such as garlic herb or chili lime, to enhance its taste further. Sprinkling cotija or feta cheese over the hot kernels adds a creamy texture and salty contrast. For a spicy kick, I serve the corn with a side of sriracha mayo or a drizzle of chipotle sauce.

I find that oven-baked corn also works well in bowls with other summer vegetables, black beans, and fresh herbs for a vibrant corn salad. Alternatively, slicing the kernels off the cob and folding them into cornbread or tacos creates interesting textures and layers of flavor.
