Ingredients
  

Bone Marrow Butter

  • 8 bone marrow halved lengthwise
  • ½ cup unsalted butter softened
  • ¼ cup fresh parsley leaves
  • ¼ cup fresh oregano leaves
  • ¼ teaspoon dried thyme
  • ¼ teaspoon salt

Chimichurri Sauce

  • 2 Tablespoons chopped fresh oregano
  • ¾ cup cilantro leaves
  • ¼ cup chopped parsley
  • Zest of ½ lemon plus 2 Tablespoons fresh lemon juice
  • 2 Tablespoons fresh lime juice
  • 1 shallot minced
  • ½ teaspoon paprika
  • 1 teaspoon kosher salt plus more to taste
  • ½ teaspoon onion powder
  • ¼ teaspoon red pepper flakes plus more to taste
  • 3 large garlic cloves
  • ½ cup extra-virgin olive oil

Oysters

  • 24 freshly shucked oysters such as Blue Point, Malpeque or fresh Gulf oysters, on the half shell
  • Hickory wood chips optional
  • Chile oil or hot sauce for serving (optional)

Instructions
 

  • Make the bone marrow butter Preheat the oven to 425 degrees. Arrange the bones marrow-side up on a rimmed baking sheet. Bake for 15 to 20 minutes, or until the marrow in the center of each bone is bubbly and soft.
  • Let the bones cool slightly, then scoop the marrow into a food processor. Add the butter, parsley, oregano, thyme and salt and puree until smooth. Season to taste.
  • Make the chimichurri In a blender or food processor, pulse all of the ingredients until very finely chopped. The sauce should look slightly chunky. Season with more salt and crushed red pepper, if needed.
  • Grill the oysters Heat a grill to 400 degrees. Gently set the oysters on the grate, being careful not to spill the oyster liquor in each shell. Top each oyster with 1 teaspoon of the marrow butter and 1 teaspoon of the chimichurri. Grill for 5 minutes, or until bubbling.
  • Spread hickory chips on 4 plates, if using. Carefully transfer 6 oysters to each plate, being careful not to spill the juices. Ignite the wood chip to add a bit more smoky flavor when served. Finish each oyster with a drop of chile oil and serve right away.
