California Grilled Corn on the Cob in Foil
Ingredients
Method
- Preheat your grill to 400°F.
- In a small bowl, mash the softened butter together with the salt, garlic powder, and black pepper until smooth and well combined.
- Rub each ear of corn with the seasoned butter mixture, then place them on large sheets of heavy-duty aluminum foil. You can wrap two ears per packet or wrap each ear individually. If using standard foil, double-layer it to prevent burning. Fold the foil over the corn and crimp the edges tightly to seal.
- Place the foil packets on the preheated grill, close the lid, and cook for 10 minutes.
- Carefully remove the packets from the grill, open them slowly to avoid steam, and flip each ear of corn. Reseal the packets and return them to the grill for another 10 to 20 minutes, until the corn is tender and just beginning to brown in spots.
- Take the packets off the grill, open them carefully, and serve the corn with extra butter and a sprinkle of salt if desired.

That’s it. Five ingredients. No complicated marinades or hard-to-find spices. You probably have everything in your pantry right now.
How to Grill Corn on the Cob in Foil Step by Step
Let me walk you through the process. I’ll share the little tricks I’ve learned so you don’t make the same mistakes I did.
Step 1: Make the Garlic Butter
Start by mashing the softened butter with the salt, garlic powder, and pepper in a small bowl. Just mix it until everything’s smooth and well combined. The smell of garlic and butter together is already making me hungry. This is the grilled corn seasoning that makes all the difference.
Step 2: Butter the Corn
Shuck the corn pull off the husks and silks. Don’t stress about every last silk strand; they’ll burn off on the grill. Rub each ear with the seasoned butter mixture. Use your hands, get messy, make sure every kernel gets some love. This is where the flavor really starts.
Step 3: Wrap in Foil Packets
Place each buttered ear on a large sheet of heavy-duty aluminum foil. You can wrap two ears per packet or individually whatever works for your grill space. Fold the foil over and crimp the edges tight. You want a sealed packet so the steam stays inside. If you’re using standard foil, double-layer it to prevent burning.
Step 4: Grill the Packets
Preheat your grill to 400°F. Place the foil packets on the grates, close the lid, and cook for 10 minutes. Then carefully flip each packet, reseal, and cook another 10 to 20 minutes. The total corn on the cob grill time is about 20 to 30 minutes. You’ll know it’s done when the corn is tender and just starting to brown in spots.
A quick note on grill lid open or closed always close it. The lid traps the heat and steam, which is what cooks the corn evenly. Opening it lets all that goodness escape.
Tips for Perfect Grilled Corn
After a few batches of trial and error, here’s what I’ve learned.
Common Grilling Mistakes to Avoid
❌ Overcooking the corn: If you leave it on too long, the kernels can get mushy. Start checking at 18 minutes if your grill runs hot.
❌ Using standard foil without double layering: Thin foil can tear or burn through. Heavy-duty foil is your friend here.
❌ Skipping the flip: Flipping halfway through ensures even cooking. Don’t skip it.
✅ The fix: Set a timer for 10 minutes, flip, then check at 20 minutes. You want tender kernels with a slight bite, not mushy ones.
If you’re wondering should you soak corn before grilling with this foil method, you don’t need to. The steam inside the packet does all the work. Soaking is really only useful if you’re grilling with the husks on.
And about butter corn before grilling yes, absolutely. The butter melts into the kernels as they cook, infusing every bite with flavor. It’s way better than adding it at the end.
How to Serve Grilled Corn on the Cob
Once those foil packets come off the grill, open them carefully there’s hot steam inside. Serve the corn with extra butter and a sprinkle of salt if you want. It’s perfect as a July 4th side dish alongside burgers, ribs, or grilled chicken.
I love setting out a little bar of toppings so everyone can customize their ear. Some ideas:
- Extra garlic butter
- A squeeze of fresh lime
- Crumbled cheese (like cotija or feta)
- A sprinkle of chili powder for heat
This grilled corn recipe is also great for elote recipe vibes just slather with mayo, dust with chili, and add cheese. But honestly, the simple garlic butter version is so good you might not want to mess with it.
How to Store and Reheat Leftovers
Got leftover corn? Lucky you. Store it in an airtight container in the fridge for up to 3 days. It’s actually delicious cold, right off the cob my kids fight over it.
To reheat, you have a few options:
- Microwave: Wrap in a damp paper towel and heat for 30-45 seconds.
- Oven: Bake at 350°F for 5-7 minutes, wrapped in foil.
- Grill: Toss the foil packets back on for 5 minutes.
You can also cut the kernels off the cob and toss them into salads, salsas, or even soups. It’s a great way to stretch leftovers into another meal.

How long does it take to grill corn on the cob on a grill?
For this foil method, it takes about 20 to 30 minutes total at 400°F. Grill for 10 minutes, flip, then another 10 to 20 minutes until tender and lightly browned. Start checking at 18 minutes if your grill runs hot.
Is it better to grill corn in foil or not?
Foil is great for tender, juicy corn with minimal effort. It steams the kernels and keeps them from drying out. Grilling without foil gives you more char and smoky flavor but requires more attention to avoid burning.
Should I butter corn before grilling?
Yes, absolutely. Buttering before grilling lets the seasoned butter melt into the kernels as they cook, infusing every bite with flavor. It’s much better than adding butter only at the end.
Can diabetics eat fresh corn on the cob?
Yes, in moderation. One ear of corn has about 17g of carbs and 2g of fiber. It can fit into a balanced diabetic diet. Pair it with protein and healthy fats to help manage blood sugar.
Do I close the lid when grilling corn?
Yes, always close the lid when grilling corn in foil. The lid traps heat and steam, which cooks the corn evenly and keeps it tender. Opening it lets the heat escape and extends cooking time.
What is the best way to cook corn on the cob on a blackstone grill?
For a Blackstone grill, use the same foil method. Preheat to medium heat (around 400°F), place the foil packets on the flat top, and cook for 10 minutes per side. The even heat distribution works great.
Why do people put aluminum foil on grills?
Aluminum foil on grills serves two main purposes: it creates a steaming environment for foods like corn, and it makes cleanup much easier by catching drips and preventing food from falling through the grates.
How long does corn need to cook on the grill in foil?
Corn in foil needs about 20 to 30 minutes at 400°F. Grill for 10 minutes, flip the packets, then cook another 10 to 20 minutes until tender. Check at 18 minutes if your grill runs hot.
Should I soak corn before grilling?
Not for this foil method. The steam inside the sealed packet keeps the corn moist and tender. Soaking is only useful if you’re grilling corn with the husks on to prevent them from burning.
What are common grilling mistakes?
Common mistakes include overcooking (makes kernels mushy), using thin foil that tears, and not flipping the packets halfway. Set a timer and use heavy-duty foil for best results.
Do you flip corn on the grill?
Yes, flip the foil packets halfway through cooking. This ensures even heat distribution and prevents one side from overcooking. Just carefully turn the packets with tongs after 10 minutes.
Does corn need to be washed before grilling?
Yes, give the shucked corn a quick rinse under cold water to remove any dirt or stray silks. Pat it dry before buttering so the butter sticks better to the kernels.
Should you remove the husks or leave them on?
For this recipe, remove the husks completely. Grilling without husks in foil gives you tender, buttery corn with easy cleanup. If you want a smokier flavor, you can grill with husks on, but it takes longer.
