Chargrilled oysters are a delightful seafood appetizer featuring oysters in their shells, topped with a flavorful Creole-seasoned compound butter, garlic, parsley, lemon zest, and finished with grated Pecorino Romano cheese. Grilled to perfection, these oysters develop a deliciously bubbling, cheesy crust, making for a savory, smoky treat perfect for entertaining or a special meal.
