Naturally sweet and gluten free, grilled corn in foil couldn’t be any simpler or tastier. Slather fresh ears of corn on the cob with my simple Parmesan herb butter, wrap them in foil, and toss on a hot grill. Twenty minutes later you’ll be enjoying some of Summer’s best flavors!
Grilled corn on the cob is a quick, easy, and fresh side dish that is the perfect complement to so many Summer favorites — grilled chicken, pork chops, smoked ribs, and fried catfish.
No grill? No problem! You can also roast corn in foil in the oven!

- Sweet corn — When choosing fresh corn at the farmer’s market or produce aisle, make sure the husks are bright green and tight to the cob, the tassels (silks) are sticky to the touch and not dry. If the tassels look black, the corn is old.
- Butter — Don’t try substituting margarine because it has too much water content. To make the flavored butter, use softened unsalted butter.
- Grated Parmesan cheese — Parmesan cheese is naturally salty so you only need to add a little salt.
How to grill corn in foil
STEP 1 | Prep the corn
- Remove the husks and silks from each ear of corn, rinse under cool water, and pat dry with paper towels.
- If you’ve never shucked fresh corn before or you have trouble removing all the silks, check out this farmer’s easy instructions!
STEP 2 | Make the buttery spread
- Garlic powder gives the herb butter a little zing. If you like, mince a clove of garlic instead.
- Place softened butter, grated Parmesan cheese, freshly chopped parsley, garlic, and a bit of salt into a bowl.
- Stir together until everything is incorporated. If you make the butter ahead of time and refrigerate it, be sure to let it come to room temperature before using.
STEP 3 | Grill in foil
- Place each ear of corn on a square of aluminum foil, then generously spread the butter all over the corn. Wrap the corn tightly in the foil and twist the ends to seal.
- Place on a hot grill and cook corn for about 20 minutes, turning occasionally, until the corn feels soft when you squeeze it with tongs.
- Be sure to use heavy duty aluminum foil (or a double layer of regular aluminum foil) to keep the corn from scorching on the grill.
Frequently asked questions
Cook the corn too long and the kernels will get chewy and tough. Perfectly cooked corn should still be crisp and look steamed when you unwrap the foil.
Follow the same recipe instructions (slathering the corn with butter and wrapping in aluminum foil), then pace the corn on a baking sheet in a 400-degree oven. Turn the corn with tongs every few minutes until it is tender, about 15 – 20 minutes.
Parmesan Corn Grilled in Foil: behind the recipe
One of the best things about Summer is getting to enjoy fresh garden vegetables, especially fresh corn! Last Saturday at the Market Square Farmer’s Market I couldn’t resist buying a few dozen ears from a Jefferson City farmer… he reminded so much of my Dad.
My Dad believed in teaching us how to work by giving us “opportunities” to help in the garden. As a teenager, the problem was that the farm schedule and my schedule didn’t always match up.
When it was time to shuck the corn, snap the beans, dig potatoes, pick strawberries, or whatever other vegetable was ripening on the vine, it didn’t matter that there might be something else I wanted to be doing instead. When I left home for college, I decided I’d had enough of farm life. Too much work. Too many bug bites. Too hot!
Now that I’m older and wiser, I appreciate the life lessons I learned growing up on the farm. My genuine appreciation for farm-fresh food stems from knowing first-hand all the work it takes from seed to harvest. I love farmers and I love fresh corn!
