Grilled Jalapeño Lime Corn on the Cob

Grilled Jalapeño Lime Corn on the Cob gives sweet summer corn a smoky, buttery finish with just the right spark of heat. The corn grills until juicy and tender, with scattered charred kernels around every ear. Meanwhile, the jalapeño softens over the flames, adding a deeper flavor without tasting harsh.

Fresh lime zest and juice keep the butter bright, while honey gently balances the pepper’s warmth. A little cumin and smoked paprika add savory depth without overpowering the corn. Finally, cotija and cilantro bring a salty, fresh finish that makes every bite pop.

Because the flavored butter goes onto the corn after grilling, there is no scorching or troublesome flare-up. Serve it with steak, chicken, salmon, or burgers. Just keep plenty of napkins nearby—beautifully buttery corn rarely stays tidy.

Recipe Yield: 6 servings

INGREDIENTS

6 medium ears fresh corn, husks and silk removed
1 medium jalapeño
1 tbsp avocado oil
6 tbsp unsalted butter, softened
2 tsp finely grated lime zest
2 tsp fresh lime juice
1 1/2 tsp honey
1/2 tsp garlic powder
1/4 tsp ground cumin
1/4 tsp smoked paprika
1/2 tsp kosher salt, divided
1/4 tsp freshly ground black pepper
1/3 cup finely crumbled cotija cheese
2 tbsp finely chopped fresh cilantro
1 medium lime, cut into wedges, for serving

INSTRUCTIONS

1. Preheat the grill:
Heat the grill to medium-high, about 425–450°F. Clean the grates thoroughly.

2. Make the lime butter:
Stir the butter, lime zest, lime juice, honey, garlic powder, cumin, smoked paprika, 1/4 tsp salt, and black pepper until evenly combined.

3. Season the corn:
Rub the corn and whole jalapeño with avocado oil. Sprinkle them with the remaining 1/4 tsp salt.

4. Grill the corn and jalapeño:
Grill the jalapeño for 6–8 minutes, turning often, until softened and charred. Grill the corn with the lid closed for 10–12 minutes, turning every 2–3 minutes, until the kernels are plump and tender with scattered golden-brown char.

5. Finish the jalapeño butter:
Cool the jalapeño for 2 minutes. Remove the stem, then discard the seeds and ribs for milder heat or leave some for extra spice. Finely chop the jalapeño and stir it into the lime butter. Divide the butter between two small bowls.

6. Butter the hot corn:
Transfer the corn to a serving platter. Immediately brush it on all sides with the butter from one bowl, allowing the heat from the corn to melt it between the kernels.

7. Garnish and serve:
Spoon the reserved clean butter over the corn. Sprinkle evenly with cotija and cilantro, then serve immediately with lime wedges.

HELPFUL TIPS TO PERFECT THIS RECIPE

• Control the jalapeño heat: Grilling mellows the pepper, but most of its heat remains around the pale ribs. Remove them completely for gentle warmth or retain a small amount for a spicier finish.
• Keep the butter away from direct flames: Honey, butter, and lime solids can scorch quickly. Adding the jalapeño lime butter after grilling gives the corn rich flavor without bitterness or flare-ups.
• Choose fresh, plump corn: Look for bright green husks and firm kernels. Fresh corn stays juicy over high heat and develops a much sweeter flavor.
• Make the butter ahead: Prepare the charred jalapeño lime butter up to two days in advance. Refrigerate it covered, then soften it at room temperature before serving.
• Use a reliable cotija substitute: Finely grated Parmesan works well when cotija is unavailable. Reduce the added salt slightly because both cheeses provide a salty finish.
