01 - Preheat grill to medium-high heat, approximately 400°F.

03 - Use a basting brush to lightly coat each ear of corn with a portion of the garlic butter mixture.
04 - Arrange corn on the grill and cook, turning occasionally with tongs, for 10 to 12 minutes, until kernels are tender and show light char marks.
05 - Remove corn from heat and immediately brush with the remaining garlic butter while hot.
06 - Sprinkle each ear generously with freshly grated Parmesan cheese, allowing it to melt slightly on the warm corn.
07 - Serve immediately, garnished with additional chopped parsley if desired.
