Grilled Parmesan Garlic Oysters

Smoky, buttery, and irresistibly savory, Grilled Parmesan Garlic Oysters are a luxurious appetizer that’s surprisingly easy to make at home. Plump oysters are grilled in their shells, bathed in garlicky butter, and finished with a golden layer of Parmesan cheese.

Behind the Recipe

The first time I had grilled oysters was at a seaside shack on the Gulf Coast, where they served them sizzling hot, bubbling with butter and cheese. That memory inspired me to recreate them at home, adding Parmesan for nutty richness and garlic for bold flavor. It’s become one of my favorite recipes to bring a taste of the coast right to the backyard grill.

Recipe Origin or Trivia

Grilled oysters have long been popular in coastal regions, particularly in Louisiana and the Gulf Coast, where seafood shacks perfected the art of serving oysters char-grilled with butter and spices. Parmesan and garlic bring an Italian-inspired twist, marrying Southern grilling traditions with Mediterranean flavors.
