Pellet Grill Smoked Corn on the Cob is an easy way to transform fresh summer corn into a side that stands up to brisket, ribs, burgers, or grilled chicken. The ears receive a brief low-temperature smoke, then a hotter finish so the kernels stay juicy and develop a touch of char.
This recipe focuses on straightforward flavor—smoky barbecue butter—while the method is the key. A pellet grill provides steady heat, clean wood smoke, and enough space to cook a full batch of corn while other items finish on the grill.
Why This Pellet Grill Smoked Corn Works
Corn cooks quickly and takes on smoke flavor fast, so it doesn’t need a long smoke to taste smoky and wood-fired. A short low-temperature stage lets the kernels absorb smoke without drying out, especially when the ears are brushed with butter before they hit the grates.
The hot finish gives the corn the texture and appearance of grilled corn instead of steamed corn. When the smoker is raised to 375°F–400°F, the natural sugars brown, the butter sizzles into the kernels, and the exterior gets little charred spots that make corn on the cob so satisfying.
Pro Tips for the Best Pellet Grill Smoked Corn
- Start low for smoke. Smoke the corn at 225°F for about 30 minutes so smoke flavor develops before increasing the heat.
- Finish hotter for texture. Raise the temperature to 375°F–400°F to brown the sugars, crisp the kernels slightly, and develop char.
- Use high heat if needed. If the grill is already hot for other items, cook the corn at higher heat—expect a more grilled than smoked result.
- Choose fresh corn. Plump ears with bright green husks and moist silk are sweeter and juicier on the smoker.
- Baste late, not constantly. Brush some butter before smoking, then save more for the hot finish and for serving to preserve fresh flavor.
Husk On or Husk Off
Smoking corn with the husks on yields a softer, more steamed texture because the husk protects the kernels from direct heat and moisture loss. The husk also blocks some smoke and limits browning.
For this method, husk-off corn cooked directly on the grates is preferred. Removing the husks exposes the kernels to smoke and allows the butter to coat them directly. The hot finish creates attractive char while keeping the inside juicy—especially when the corn is very fresh.
Ingredient Tips
- Fresh sweet corn matters most. Look for ears that feel heavy for their size, with bright green husks and moist silk.
- Unsalted butter gives you control. Use unsalted butter so you can adjust salt according to your barbecue seasoning.
- Barbecue spice blend adds backbone. A smoky, lightly sweet dry rub complements the corn and the butter.
- Lime juice at the end. Add lime after smoking to brighten the finished flavor; adding citrus too early will lose its freshness.
- Fresh herbs are optional. Cilantro or parsley add color and a fresh contrast to the smoky butter.
Substitutions and Variations
For a street-corn (elote) style, brush the finished corn with a little mayo, then sprinkle cotija cheese, add lime, cilantro, and a dusting of chili powder. For a richer option, add grated Parmesan immediately after the corn comes off the grill so it melts into the butter.
Sweeten the butter with a spoonful of honey, or add heat with hot sauce or extra barbecue spice. Mild fruit woods—apple, cherry, pecan, or maple—work well in pellet grills; they complement the corn’s sweetness without overpowering it.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to four days. Keep the corn on the cob intact or cut the kernels off for use in salads, rice bowls, tacos, or scrambled eggs.
To reheat corn on the cob, wrap loosely in foil with a bit of butter and warm on the pellet grill or in the oven until heated through. Reheat cut kernels in a skillet with a small pat of butter until warm and lightly browned.
Frequently Asked Questions
About 45–60 minutes total: roughly 30 minutes at 225°F, then 15–20 minutes at 375°F–400°F for the hot finish.
Either works. Husks-on steams and protects the ear, while husks-off yields more smoke flavor and better browning.
No—when cooking husk-off on a pellet grill, fresh corn stays juicy without soaking. Avoid overcooking to prevent drying.
Kernels should be tender and juicy and easily pierced with a fork. The exterior will show light char but the kernels should not be shriveled.

Pellet Grill Smoked Corn on the Cob
Equipment
- Pellet grill or smoker
- Basting brush
- Tongs
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 fresh lime juice
- 2 tbsp fresh cilantro, chopped (optional)
Instructions
- Preheat the pellet grill smoker to 225°F using your preferred pellets.
- Remove husks and silk from the corn. Lightly brush ears with olive oil so butter and seasoning adhere.
- Stir melted butter and barbecue seasoning together in a small bowl.
- Brush each ear with about half of the barbecue butter.
- Place ears directly on the grill grates and smoke at 225°F for 30 minutes, turning once halfway through.
- Increase the temperature to 375°F–400°F. Baste with more butter and cook 15–20 minutes, turning every few minutes, until kernels are tender and lightly charred in spots.
- Remove corn, brush with the remaining butter, finish with lime juice and chopped cilantro or parsley, and serve warm.
Notes
Use Fresh Corn
Fresh sweet corn delivers the best texture and flavor. Seek ears with bright husks, moist silk, and plump kernels.
Husked or Unhusked
Remove husks for greater smoke and color, or pull them back and tie for presentation—keep husks away from direct flame if left partially attached.
Smoke Flavor
Use mild woods such as apple, cherry, pecan, or maple. Corn absorbs smoke quickly, so mild wood keeps the balance and lets sweetness shine.
Butter and Seasoning
Brush with butter before serving and season while hot. Salt, pepper, smoked paprika, chili powder, lime, and fresh herbs all pair well.
Serving Tip
Serve immediately while hot and juicy. If the corn must rest for a short time, tent loosely with foil to keep it warm without over-steaming.
