How to Cook Corn: Stovetop, Grill, Oven and Microwave

Wondering how to cook corn? Below are six reliable methods to cook fresh corn so the kernels stay sweet, tender and flavorful every time. I’ll also cover how to select the best ears at the store, how to shuck them, storage tips, freezing, and a few topping ideas to elevate your corn on the cob.

How to Pick the Best Corn at the Store

• Feel the ear—good corn should be firm and heavy for its size.
• Look for husks that are bright green, tightly wrapped and slightly damp; this indicates freshness.
• Avoid ears with brown or slimy spots on the husk or visible holes.
• Check the silk (the tassel at the top). It should smell sweet and feel slightly sticky—dry, dark or moldy silk can mean older corn.

How to Remove the Corn’s Husk

The easiest shucking method is simple: pull down the outer husk from the top to the base in one motion, then peel away the layers and remove the silk. Another trick is to trim the stalk end and stand the ear upright in a sturdy container while peeling the husk downward. If some silk remains, use a damp paper towel to rub it off—this helps keep the kernels clean without damaging them.

How to Cook Corn — 6 Ways

All of the methods below assume the corn has been shucked and silk removed. Choose the method that best fits your schedule and desired texture.

How to Boil Corn

• Fill a large pot with water and bring it to a rolling boil.
• Add the ears of corn and cover the pot so the water returns to a boil quickly.
• Cook for 5–7 minutes, depending on the size and freshness. Fresh ears may need less time. The kernels should be tender and bright in color.

How to Cook Corn in the Instant Pot

• Pour 1 cup of water into the Instant Pot and set the trivet in the bottom.
• Place the shucked ears on the trivet; stack if necessary.
• Seal and cook on High Pressure for 2 minutes, then quick release the steam.

How to Grill Corn

• Brush each ear with olive oil or softened butter to help char and prevent sticking.
• Place corn on a hot grill and cook 8–12 minutes, turning every couple of minutes to achieve an even char. Flip more frequently for lighter char, less often for deeper charring.

How to Microwave Corn

• Wrap each ear in a damp paper towel and place in a microwave-safe dish with a lid or cover the plate.
• Microwave on high for 3–5 minutes, depending on your microwave and the size of the ears. Let cool slightly before unwrapping.

How to Oven Roast Corn

• Preheat the oven to 375°F (190°C).
• Place each ear on a sheet of foil, add a pat of butter if you like, and wrap tightly.
• Bake for about 30 minutes or until kernels are tender. For a bit of color, open the foil and broil for 1–2 minutes at the end.

How to Steam Corn

• In a pot with a steamer basket, bring 1 to 1½ cups of water to a boil—enough so the steamer isn’t submerged.
• Add the ears to the basket, cover, and steam for 5–6 minutes, until the kernels are tender but still juicy.

How to Store Corn

Store fresh corn in the refrigerator with the husks on if possible. Place ears in a plastic bag in the crisper drawer and use within 2–3 days for best sweetness and texture. The sugars in corn convert to starch over time, so the sooner you eat it, the sweeter and more tender the kernels will be.

How to Store Leftover Cooked Corn

Allow cooked corn to cool to room temperature, then wrap tightly in foil or plastic wrap and refrigerate. Stored this way, cooked corn keeps well for up to 5 days.

Can You Freeze Corn?

Yes. For whole ears, place cooled ears on a baking sheet in a single layer and freeze until solid, then transfer to an airtight freezer bag or container. You can also cut kernels off the cob and freeze them in a single layer before bagging. Frozen corn keeps well for 3–4 months.

Can I Add Salt to the Water When Boiling?

It’s best to skip salt in the boiling water. Salted water can toughen the kernels. Instead, season the corn after cooking with butter, salt, spices, or a finishing sauce.

How to Tell When Corn on the Cob Is Done

Cooked corn should be bright, glossy and the kernels should look plump and slightly swollen. Taste one kernel—when it’s tender and juicy, the ear is done. Avoid overcooking, which makes kernels mealy and less sweet.

Making Corn for a Crowd?

If you’re cooking multiple batches, keep cooked ears warm in a large covered baking dish or wrapped in foil until ready to serve. This helps retain moisture and keeps the corn tender while you finish cooking other batches.

Topping Ideas for Corn on the Cob

Experiment with flavors—corn is a great canvas for herbs, spices and sauces. Popular ideas:

• Chili powder, cotija cheese, chopped cilantro and a squeeze of lime for a Mexican-style street corn.
• Lime-coconut crema for a bright, tropical twist.
• Honey butter or herb-infused butter for a sweet or savory finish.
• Miso butter or chipotle mayo with lime for rich umami or smoky heat.

Try these methods to find your favorite way to cook corn. Whether you’re boiling, grilling, steaming, microwaving, oven-roasting or using an Instant Pot, the goal is the same: preserve the sweet, juicy quality of fresh corn without overcooking it. Enjoy!
