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 the grill. Cook for 12 to 15 minutes, rotating every 3 to 4 minutes, until kernels are tender and display light charring.
06 - Remove corn from grill and immediately sprinkle the parmesan-ranch mixture over each ear, pressing gently to adhere.
07 - Serve immediately, garnished with additional fresh herbs if desired.
