Blackstone Grilled Corn on the Cob (Easy + Buttery!)

There’s nothing better in summer than Blackstone grilled corn on the cob — sweet kernels caramelized over high heat with butter, salt, and a little char on every side. In about 15 minutes on the griddle, you’ll have the easiest side dish for any cookout, BBQ, or weeknight dinner.

If you loved my Air Fryer Roasted Corn, you’re going to go bonkers over grilling it on the Blackstone. The flat griddle gives you even browning and those golden char marks you just can’t get from boiling.

My husband is from Ohio, and the man takes his corn seriously — his mom used to make a big batch and eat the leftovers cold for breakfast. Once you taste corn off the griddle, you’ll understand why.

Why You’ll Love This Blackstone Corn Recipe

• Big charred flavor. The Blackstone’s high, even heat caramelizes the natural sugars in the corn and adds a smoky, grilled taste you can’t get from a pot of water.
• Fast and hands-off. Husk, oil, season, and griddle — start to finish in about 15 minutes.
• No husks, no foil, no fuss. Cooking the corn naked on the flat top gives you the best char and the least cleanup.
• Endlessly customizable. From Mexican street corn to garlic-herb butter, the griddle is a blank canvas (full variations below).
• Perfect for a crowd. A Blackstone fits a dozen ears at once, so it scales beautifully for parties.

Can You Cook Corn on the Cob on a Blackstone?

Absolutely. The Blackstone griddle is one of the best ways to cook corn on the cob. The flat surface keeps every kernel in contact with the heat, so you get even cooking and gorgeous char marks. Cook the corn directly on the griddle — skip the foil, since wrapping it steams the corn and prevents the browning that makes this method special.

Ingredients You’ll Need

The full ingredient amounts and step-by-step directions are in the printable recipe card at the bottom of this post, along with nutrition info.

• Corn on the cob — Fresh, husked ears are the star. Look for bright green husks and plump, springy kernels (more tips on picking corn below).
• Olive oil or melted butter — Coats the corn so it browns evenly and doesn’t stick. Butter adds richness; olive oil gives a cleaner char.
• Salt and pepper — The baseline seasoning that makes the corn’s sweetness pop.
• Optional add-ons — Paprika, garlic powder, or fresh herbs for the rub; lime juice and grated cheese (Parmesan or Cotija) to finish.

How to Grill Corn on the Cob on a Blackstone

Step 1: Heat your Blackstone to medium-high, about 375–400°F, and let it come fully up to temperature.

Step 2: Husk the ears and pull off any silk. Brush each one all over with olive oil or melted butter, then season with salt and pepper (plus any optional spices).

Step 3: Place the ears directly on the hot surface — no foil. Cook 10–15 minutes, turning every couple of minutes so all sides char evenly. The corn is ready when it’s nicely charred and the kernels are tender but still have a little bite. Pierce a kernel with a fork to test.

Step 4: Brush with extra butter, sprinkle with herbs or cheese, and add a squeeze of lime if you like. Serve hot off the griddle.

How to Pick the Best Corn

• Look for bright green, snug husks that wrap tightly around the ear — avoid dried-out or yellowing husks.
• Feel for plump kernels all the way to the tip; gaps mean the corn is past its prime.
• Check the silk — it should be pale gold and slightly sticky, not brown and dry.
• Buy it fresh and use it fast. Corn’s sugars turn to starch quickly, so grill within a day or two of buying for the sweetest flavor.

Recipe Tips for the Best Griddle Corn

Serve immediately. Griddle corn is at its best straight off the heat.

Get the griddle fully preheated before the corn goes on — a cool surface gives you pale, unevenly cooked ears.

Don’t crowd the flat top. Leave a little space between ears so they char instead of steam.

Turn often. Rotating every 2–3 minutes is the trick to even color without burning.

Season before and after. Salt before cooking, then finish with butter, cheese, or lime once the corn comes off.

Flavor Variations to Try

• Italian Pesto: Brush the hot corn with basil pesto and finish with grated Parmesan and a squeeze of lemon.
• Mexican Street Corn (Elote): After grilling, brush with mayo, then sprinkle with Cotija, lime juice, chili powder, and fresh cilantro.
• Garlic Herb Butter: Stir minced garlic and chopped parsley into melted butter; brush on before and during grilling.
• Spicy Sriracha Lime: Combine melted butter, Sriracha, and lime juice; baste while grilling and top with cilantro.
• Parmesan Lemon: Finish the grilled corn with butter, grated Parmesan, lemon zest, salt, and pepper.
• Honey Butter: Mix melted butter with honey and a pinch of salt for a sweet-savory glaze.
• Smoky BBQ: Blend melted butter with BBQ sauce and smoked paprika; baste throughout cooking.
• Asian-Style: Whisk soy sauce, sesame oil, and garlic powder; brush on and finish with green onion and sesame seeds.

How to Store and Reheat

• Refrigerate: Store cooled corn in an airtight container for up to 4 days.
• Reheat: Warm ears back on the griddle for a couple of minutes per side, or microwave for 30–60 seconds. See my guide to reheating corn on the cob for more methods.
• Cut it off the cob: Slice the kernels off and toss them into summer salads, salsa, or creamed corn.

Blackstone Grilled Corn FAQs

What temperature should I cook corn at on a Blackstone? Medium-high, around 375–400°F. That’s hot enough to char the kernels without burning them before they cook through.

How long does corn take on a Blackstone griddle? About 10–15 minutes, turning every few minutes so all sides brown evenly.

Should I use oil or butter? Either works — both help the corn brown and keep it from sticking. Butter adds richness; olive oil gives a cleaner, higher-heat char. You can also brush on more partway through.

Do I need to wrap the corn in foil? No — and you shouldn’t if you want char. Cook the corn directly on the griddle. Foil steams it and prevents browning.

Can I cook frozen corn on the cob on a Blackstone? Yes. Thaw it first, then pat dry, oil, season, and griddle as usual. Frozen corn may need an extra minute or two.

How do I know when the corn is done? It’s done when it’s charred in spots and the kernels are tender. Pierce a kernel with a fork — it should be tender with a slight firmness.

Can I grill other vegetables alongside it? Definitely. Bell peppers, zucchini, and onions all cook well on the griddle using the same method and timing.
