Units of Measurement:
4 Cup rock salt
18 Large oysters
4 Tablespoon unsalted butter
2 Clove garlic, minced
As Needed kosher salt
12 Medium Lemon wedges, for serving
2 Tablespoon minced shallot
1/4 Cup Red wine vinegar
1/2 Teaspoon freshly ground black pepper


  • 1

    Choose a shallow serving platter that will hold all of the oysters. Pour the rock salt onto the platter to create a 1/2 inch base. This will steady the oysters for serving.

  • 2

    To prepare the oysters, check to ensure they are completely closed. Discard oysters that are not. Wash and lightly scrub the oysters to ensure there is no grit on the surface. This will prevent the grit from entering the oyster once shucked.

  • 3

    Using a thick glove or kitchen towel, sturdy the oyster in the hand opposite of the one holding the knife. Using an oyster knife or very sturdy paring knife, locate the “hinge” on each oyster. Place the point of the knife in the hinge, and wiggle the tip of the knife into the oyster until it feels sturdy. Firmly turn the knife to apply a torquing pressure to gently open the oyster.

  • 4

    Remove the top shell of the oyster. Using the tip of the knife, loosen the oyster from its shell, leaving the juices intact. Place each loosened oyster on its half shell on a baking sheet.

  • 5

    When ready to cook, set the Traeger temperature to 450℉ and preheat with the lid closed for 15 minutes.

    450 ˚F / 232 ˚C

  • 6

    In a small saucepan, melt the butter over medium-low heat. Add the garlic and a generous pinch of salt, and cook until fragrant but not burned, about 1 minute. Remove from the heat.

    450 ˚F / 232 ˚C


  • 7

    For the Mignonette: Combine the minced shallot, red wine vinegar and 1/2 teaspoon freshly ground black pepper. Set aside.

  • 8

    Spoon 1 teaspoon of the garlic butter sauce onto each oyster in its half shell. Carefully place each oyster directly on the grill grates, ensuring they don’t slip. Close the lid and allow them to cook for 3 to 4 minutes, until the edges of the oysters have pulled away from the shell. Remove carefully with tongs to keep the juices and butter in the shells. Place directly on the rock salt to balance them. Serve immediately with the mignonette and lemon wedges to squeeze onto the oysters. Enjoy!
