01 - Preheat your grill to medium-high heat, approximately 400°F.
02 - In a small bowl, combine melted butter with finely chopped parsley, chives, and dill. Mix thoroughly until evenly distributed.
03 - In a separate bowl, mix grated parmesan cheese, ranch seasoning powder, garlic powder, and black pepper until well combined.
04 - Brush each ear of corn generously with the prepared herb butter mixture, ensuring full coverage on all sides.
05 - Place corn directly on the preheated grill grates. Cook for 12–15 minutes, rotating every 3–4 minutes, until kernels become tender and develop light char marks.
06 - Remove corn from the grill. While still hot, sprinkle the parmesan-ranch mixture evenly over each ear, pressing gently to adhere the coating.
07 - Serve immediately while warm, garnished with additional chopped parsley or chives if desired.
