Grilled Corn on the Cob in Foil
Ingredients
Method
- Preheat your grill to 400°F.
- In a small bowl, mash the softened butter with the salt, garlic powder, and black pepper until well combined and smooth. A fork works perfectly for this.
- Rub each ear of corn all over with the seasoned butter mixture. Tear off large sheets of heavy-duty aluminum foil (or double up regular foil) and place 2 ears on each sheet. Fold the foil up and over the corn, crimping the edges tightly to form a sealed packet.
- Place the foil packets directly on the grill grates. Close the lid and cook for 10 minutes.
- Using tongs, carefully remove the packets from the grill. Open one end of each packet (watch out for steam), flip the ears of corn, and reseal the packets. Return to the grill.
- Continue grilling for another 10 to 20 minutes, until the corn is tender and just beginning to brown in spots. Cooking time varies by grill; check after 18 minutes.
- Carefully open the packets, transfer the corn to a platter, and serve hot with extra butter and a sprinkle of salt if desired.

Let us know how it was!Why This Grilled Corn in Foil Works
The grill is fired up, burgers are sizzling, and you’re standing there thinking… what about the corn? I’ve been there. My first time grilling corn, I threw it straight on the grates without a plan. The husks caught fire, the kernels came out dry, and I ended up serving something that looked more like charcoal than a side dish. Not my finest moment.
But here’s the thing – I figured it out. And I promise, this method changes everything. Grilling corn on the cob in foil is hands-down the easiest, most foolproof way to get tender, juicy kernels every single time. No burnt husks, no dried-out cobs, no stress. Just perfectly cooked corn that tastes like summer.
The foil packet method works because it traps steam around the corn while it cooks. That steam keeps the kernels plump and tender, while the butter and seasonings you add infuse every single bite. It’s like a little flavor sauna in there. And the best part? You get that subtle smoky flavor from the grill without worrying about anything burning.
This might just be the easiest thing you grill all summer. Seriously.
Ingredients You’ll Need
One of the reasons I love this grilled corn on the cob recipe is how simple the ingredient list is. You probably have most of this stuff already. Here’s what you need:
- Unsalted butter, softened – 4 tablespoons. Softened is key here. Cold butter won’t spread evenly over the corn, and we want every kernel coated.
- Salt – 1/4 teaspoon in the butter mixture, plus more for serving. I use fine sea salt.
- Garlic powder – 1/2 teaspoon. This adds a subtle savory depth without being overpowering.
- Freshly ground black pepper – 1/8 teaspoon. Just a touch for warmth.
- Ears of corn – 6 ears, shucked. Look for corn that feels heavy for its size with bright green husks and moist silks. Fresh corn is sweeter and more tender.
That’s it. Five ingredients. You don’t need a long list of fancy stuff to make amazing corn on the cob on grill. The magic happens in the technique.
One quick note about the corn itself – peak season for corn is summer, usually June through August. That’s when you’ll find the sweetest ears at your local farmers market or grocery store. But honestly, this method works well even with slightly older corn, because the steam in the foil helps plump things up.
How to Grill Corn in Foil
Okay, let’s get into the actual process. I’m going to walk you through the four main stages of making this grilled corn on the cob in foil. Think of these as the big-picture steps – the recipe card above has all the details, but here’s where I explain the why behind each stage.
Stage 1: Make Your Seasoned Butter
Before you even think about the grill, you need to get your butter ready. Take those 4 tablespoons of softened unsalted butter and put them in a small bowl. Add the salt, garlic powder, and black pepper. Then just mash it all together with a fork until it’s smooth and evenly combined.
I love this part because the smell of garlic powder mixing with butter is just… chef’s kiss. It’s simple, but it sets the foundation for the whole dish. You can do this while the grill is preheating, so no wasted time.
Stage 2: Butter the Corn and Wrap It Up
Now take each ear of shucked corn and rub it all over with that seasoned butter mixture. Don’t be shy – get it into every nook and cranny between the kernels. This is where the flavor happens.
Next, tear off large sheets of heavy-duty aluminum foil. If you’re using regular foil, double it up so nothing leaks out. Place two ears of corn on each sheet, then fold the foil up and over them. Crimp the edges tightly to form a sealed packet. You want it airtight so the steam stays inside.
This is the crucial step for how to grill corn on the cob without it drying out. That sealed packet creates a mini steamer that keeps everything moist and tender.
Stage 3: Grill the Packets
Place the foil packets directly on the grill grates. Close the lid and let them cook for 10 minutes. Then, using tongs, carefully remove the packets from the grill. Open one end of each packet – watch out for that burst of steam, it’s hot – flip the ears of corn, and reseal the packets. Return them to the grill.
Continue grilling for another 10 to 20 minutes. I know that’s a range, but it really depends on your grill and how hot it runs. Start checking at 18 minutes total cook time. The corn is done when it’s tender and just beginning to brown in spots. You want those little charred marks for flavor, but not so much that the kernels get tough.
If your grill runs hot, definitely check at 18 minutes. I’ve had some grills that cook the corn perfectly in 18 minutes, and others that need the full 25. Trust your eyes and a quick poke with a fork.
Stage 4: Serve It Hot
Carefully open the packets – seriously, that steam is no joke – and transfer the corn to a platter. Serve hot with extra butter and a sprinkle of salt if you want. The butter will melt into the hot kernels, and that first bite of smoky, buttery corn is just pure summer bliss.
You can also add a squeeze of lime or a dusting of chili powder at this point if you’re feeling adventurous. But honestly? The simple version is so good on its own.
Tips for Perfect Grilled Corn
After making this best grilled corn more times than I can count, I’ve picked up a few tricks that make a real difference. Here are the ones I swear by:
- Don’t skip flipping the corn halfway. This ensures even cooking and prevents one side from getting too done while the other stays raw.
- Use heavy-duty foil. Regular foil can tear when you flip the packets, and then you lose all that precious steam. Double up if that’s all you have.
- Let the packets rest for a minute before opening. The steam inside is extremely hot. Give it a few seconds to settle down before you peel back the foil.
- If you want a smoky char, open the packets at the end and place the corn under the broiler for 1-2 minutes. This gives you those beautiful char marks without overcooking the kernels.
One common mistake I see? People try to rush the process. Grilling corn isn’t something you can hurry. Let it cook through, let the steam do its job, and you’ll be rewarded with the most tender, flavorful corn you’ve ever had.
Quick Troubleshooting
❌ My corn is undercooked: The kernels feel hard and don’t give when you poke them. ✅ Solution: Reseal the packets and grill for another 5-10 minutes. Check again. Every grill is different.
❌ The husk is burning (if grilling with husk): You forgot to soak the corn first. ✅ Solution: For husk-on grilling, soak corn in cold water for at least 15 minutes before grilling. This prevents the husk from catching fire.
❌ The kernels are dry: You cooked them too long without the foil. ✅ Solution: Always use foil packets for tender corn. If you want char marks, add them at the very end under the broiler.
Flavored Butter Variations
The base recipe is fantastic as-is, but sometimes you want to mix things up. Here are a few ways to customize your butter for grilled corn:
- Cilantro Lime Butter: Mash 1 tablespoon of chopped fresh cilantro and 1 teaspoon of lime zest into the softened butter along with the seasonings. It adds a bright, fresh flavor that’s perfect with the smoky corn.
- Chili Lime Corn: After grilling, slather the corn with a little mayo (trust me), then dust with chili powder and squeeze fresh lime juice over the top. Sprinkle with Cotija cheese if you have it. This is basically elotes, and it’s incredible.
- Herb Butter: Mix in 1 tablespoon of finely chopped fresh parsley or chives with the butter. It adds a lovely garden-fresh note.
These are all optional, of course. The base recipe with just garlic and pepper is already a crowd-pleaser. But if you want to impress your guests even more, these variations are the way to go.
How to Serve Grilled Corn on the Cob
This easy BBQ side dish pairs beautifully with so many summer meals. Here are some of my favorite ways to serve it:
- Alongside burgers and hot dogs – It’s a classic for a reason. The sweet corn balances the savory meat perfectly.
- With grilled chicken or steak – The smoky flavors complement each other wonderfully.
- As part of a summer spread – Serve it with coleslaw, potato salad, and baked beans for a full cookout menu.
- In salads or salsas – Slice the kernels off the cob and toss them into a fresh salad or salsa. It adds sweetness and texture.
One of my favorite things to do is slice the kernels off leftover grilled corn and add them to a black bean salad with lime and cilantro. It’s a whole new dish in minutes.
Storing and Reheating Leftovers
If you somehow have leftover grilled corn on the cob – which honestly, doesn’t happen often in my house – here’s how to handle it:
Storage: Store leftover grilled corn in an airtight container in the fridge for up to 3 days. You can keep it on the cob or cut the kernels off first. I usually cut them off because it takes up less space and makes them easier to use later.
Reheating: The best way to reheat grilled corn is to wrap it in a damp paper towel and microwave for 30-45 seconds. This adds a little moisture back. You can also reheat it in a skillet over medium heat for a few minutes, which gives you a bit of char again.
Freezing: You can freeze grilled corn! Cut the kernels off the cob, spread them on a baking sheet, and freeze until solid. Then transfer to a freezer bag. They’ll keep for up to 3 months. Use them in soups, chowders, or salsas straight from the freezer.
Leftover ideas: Besides salads and salsas, try adding the kernels to cornbread batter, mixing them into mac and cheese, or using them as a topping for tacos. The smoky flavor adds something special to any dish.
