01 - Preheat your grill to medium-high heat, approximately 400°F.
02 - Combine melted butter, parsley, chives, and dill in a small bowl, mixing thoroughly.
03 - In a separate bowl, blend parmesan cheese, ranch seasoning, garlic powder, and black pepper until uniform.
04 - Brush each ear of corn generously with the herb butter mixture, ensuring even coverage.
05 - Place corn directly on grill grates. Cook for 12–15 minutes, rotating every 3–4 minutes, until kernels are tender and lightly charred.
06 - Remove corn from grill and immediately sprinkle parmesan-ranch mixture evenly over each ear while hot, pressing gently to adhere.
07 - Serve immediately with additional chopped herbs as garnish if desired.
