Serves: 1 dozen
  • 1 dozen oysters on the half shell
  • 2 cups softened butter
  • ½ cup minced garlic
  • ½ cup grated Pecorino Romano cheese
  • 1 tablespoon chopped flat-leaf parsley
  • 1 tablespoon chopped rosemary
  • 1 tablespoon freshly ground black pepper
  • 1 teaspoon Acadiana Table Cajun Seasoning Blend, see recipe here
  • 1 teaspoon hot sauce
  • ½ cup grated Parmigiano-Reggiano cheese
  1. Preheat a gas grill (or charcoal grill) to high. The internal temperature should be 450ºF or higher.
  2. Line a large metal tray with parchment paper (keeps the oysters from sliding around) and place on the side of the grill.
  3. In a medium-size sauce pan, add all of the ingredients and stir together until thoroughly combined. Place the pan on a warm part of the grill so that the butter mixture will melt..
  4. Once the grill is hot, add the oysters in their half-shells to the grill’s hottest part. Using a long-handled spoon, add a heaping tablespoon of the butter mixture to each oyster. The amount of butter should be enough to spill over into the hot burners to create flames and smoke, essential for the char-grilled flavor. Top each oyster with grated Parmigiano-Reggiano cheese. Using a spray bottle of water, spritz the flames down. As the steam rises, close the grill cover and let cook unopened for 1 minute. Open and check to see that the edges of the oysters are beginning to curl, the sign that the oysters are cooked but not overcooked.
  5. As they are ready, remove the oysters to the metal tray. (Note: The tray can be placed in a 150ºF oven to keep warm if you are cooking more oysters.) Serve the oysters with crusty French bread for sopping up the sauce.
If using the frozen half-shell oysters, place them on the grill frozen; they will thaw in just a minute or two, and then you can add your sauce. Watch carefully. Your grill will have hot spots where the oysters will cook quicker than others; remove those oysters earlier to prevent burning. These half-shell oysters can be prepared in a 400ºF oven, but you will miss the flavor of the smoke and flame.
