Pellet Grill Smoked Corn on the Cob is one of the easiest ways to turn fresh summer corn into a side dish that tastes like it can truly stand up next to brisket, ribs, burgers, or grilled chicken at your BBQ. The corn gets a low smoke first, then a hotter finish so the kernels stay juicy and pick up a little char.
This recipe keeps the flavor simple with smoky barbecue butter, but the method is the important part. A pellet grill smoker gives you steady heat, a clean wood-fired flavor, and enough room to cook a batch of corn while the rest of dinner is already on the grill.

Why This Pellet Grill Smoked Corn Works
Corn cooks quickly, so it does not need a long smoke to get that delicious smoked flavor. A short low-temperature stage gives the kernels time to pick up smoke without drying out, especially when the corn is brushed with butter before it hits the grates.
The hotter finish is what makes this feel like grilled corn instead of steamed corn. Once the smoker climbs to 375°F to 400°F, the natural sugars in the corn start to brown, the butter sizzles into the kernels, and the outside picks up those little charred spots that make corn on the cob so good.
Pro Tips for the Best Pellet Grill Smoked Corn
Start low for smoke. Give the corn about 30 minutes at 225°F so the smoke has time to settle into the kernels before the grill gets hot.
Finish hotter for texture. After the low-smoke stage, raise the pellet grill to 375°F to 400°F so the corn turns from simply smoked to grilled, buttery, and lightly charred.
Use high heat when needed. If your pellet grill is already running hotter for burgers, chicken, or steaks, you can cook the corn at the higher temperature, but it will taste more grilled than smoked.
Use fresh corn. Look for plump ears with bright green husks and moist silk because fresh corn is sweeter and stays juicier on the smoker.
Baste late, not constantly. Brush some butter on before smoking, then save more for the hot finish and serving so the flavor stays fresh instead of cooking off early.
Husk On or Husk Off
You can smoke corn with the husks on, but it gives you a softer, more steamed result. The husk protects the kernels from drying out, which can be helpful, but it also blocks some smoke and keeps the corn from picking up much color.
For this recipe, I prefer husk-off corn cooked directly on the grates. It gets more smoke, the butter hits the kernels directly, and the hot finish can lightly char the outside. If your corn is very fresh, it will stay juicy without soaking or wrapping.
Ingredients Tips
Fresh sweet corn matters most. Look for ears that feel heavy for their size, with bright green husks and silk that still looks moist instead of dry or brittle.
Unsalted butter gives you control. It carries the barbecue seasoning into the kernels and lets you adjust the salt level based on the spice blend you use.
Barbecue spice blend adds the backbone. My homemade barbecue spice blend brings smoky, savory, lightly sweet flavor without needing a separate seasoning mix for the corn.
Lime juice should go on at the end. A small squeeze brightens the butter and corn after smoking, but adding it too early can dull the fresh citrus flavor.
Fresh herbs are optional but helpful. Cilantro or parsley makes the finished corn look brighter and adds a fresh contrast to the smoky butter.
Substitutions and Variations
For a street-corn style version, brush the finished corn with a little mayo, then add cotija cheese, lime, cilantro, and a dusting of chili powder. For a richer cookout-style version, add Parmesan cheese right after the corn comes off the grill so it melts into the butter.
You can also make the butter sweeter with a spoonful of honey, or spicier with hot sauce or a little extra barbecue spice blend.
Apple, cherry, pecan, and maple pellets are all good choices because they bring smoke without overpowering the corn’s sweetness.
Storage and Reheating
Store leftover smoked corn in an airtight container in the refrigerator for up to 4 days. You can keep it on the cob or slice the kernels off and save them for salads, rice bowls, tacos, or scrambled eggs.
To reheat corn on the cob, wrap it loosely in foil with a little butter and warm it on the pellet grill or in the oven until heated through. For kernels cut off the cob, reheat them in a skillet with a small pat of butter until warm and lightly browned.
Frequently Asked Questions
Plan on about 45 to 60 minutes total. This recipe smokes the corn at 225°F for 30 minutes, then finishes it hotter at 375°F to 400°F for 15 to 20 minutes.
You can do either, but husk-off corn gets more smoke and better color. Husk-on corn stays protected and steams more, but it will not pick up as much char.
No, not for husk-off corn cooked directly on the pellet grill. Fresh corn stays juicy on its own, especially when it is brushed with butter and not overcooked.
For smoked corn, start at 225°F and then finish at 375°F to 400°F. For faster grilled corn, Traeger also recommends high heat, but the lower start gives you more smoke flavor.
The kernels should be tender, juicy, and easy to pierce with a fork. The outside should have light char in spots, but the kernels should not look shriveled or dry.

Pellet Grill Smoked Corn on the Cob
Ingredients
- 6 ears corn on the cob, fresh, husks and silk removed
- 1 tbsp olive oil
- 6 tbsp unsalted butter, melted
- 1 ½ tbsp barbecue seasoning dry rub
- 1 tbsp lime juice, fresh
- 2 tbsp cilantro, fresh, chopped
Instructions
- Preheat the pellet grill smoker to 225°F using your favorite pellets.
- Remove the husks and silk from the corn. Brush the corn lightly with olive oil so the butter and seasoning cling to the kernels.
- Stir the melted butter and barbecue spice blend together in a small bowl.
- Brush the corn with about half of the smoky barbecue butter.
- Place the ears directly on the grill grates and smoke for 30 minutes, turning once halfway through.
- Increase the pellet grill temperature to 375°F to 400°F. Brush the corn with more butter, then cook for 15 to 20 minutes, turning every few minutes, until the kernels are tender and lightly charred in spots.
- Remove the corn from the grill and brush with the remaining butter. Finish with lime juice and chopped cilantro or parsley. Serve warm.
Notes
Use Fresh Corn
Fresh sweet corn gives you the best flavor and texture. Look for ears with bright green husks, moist silk, and plump kernels.Husked Or Unhusked Corn
You can smoke corn with the husks removed for more direct smoke flavor, or leave the husks pulled back and tied for presentation. If leaving some husk attached, keep it away from direct heat so it does not burn too quickly.Smoke Flavor
Use a mild wood such as apple, cherry, pecan, or a competition blend. Corn takes on smoke quickly, so a mild wood keeps the flavor balanced and lets the sweetness of the corn come through.Butter And Seasoning
Brush the corn with butter before serving and season it while it is still hot. Salt, pepper, garlic powder, smoked paprika, chili powder, lime juice, or fresh herbs all work well.Serving Tip
Serve the corn right away while it is hot and juicy. If it needs to sit for a few minutes, tent it loosely with foil so it stays warm without steaming too much.Nutrition
