01 - Heat the grill to medium-high, approximately 400°F.
02 - In a small mixing bowl, blend softened butter with minced garlic, chopped parsley, salt, and black pepper until a uniform paste forms.
03 - Lightly coat each ear of corn with a portion of the garlic butter mixture using a basting brush.
04 - Arrange corn on the grill and cook, turning every few minutes, for 10 to 12 minutes until kernels are tender and just charred.
05 - Remove corn from the grill and immediately brush the remaining garlic butter evenly over the hot ears.
06 - Generously sprinkle grated Parmesan cheese over each ear of corn while still hot to allow the cheese to melt slightly.
07 - Serve promptly, garnished with extra chopped parsley if desired.
