Ingredients

  • 8 tablespoons (1 stick) unsalted butter
  • 4 minced shallots
  • 4 cloves minced garlic
  • 1 cup diced applewood bacon, sliced into lardons
  • 1 teaspoon kosher salt
  • 2 tablespoons all-purpose flour
  • 1/4 cup anise-flavored liqueur, such as sambuca or Pernod
  • 1/2 cup heavy cream
  • 2 cups baby spinach
  • 1/2 teaspoon freshly ground nutmeg
  • 1 teaspoon fresh ground black pepper
  • 1/2 teaspoon red pepper flakes, optional
  • 3/4 cup seasoned breadcrumbs
  • 18 large oysters, shells scrubbed and rinsed
  • 2 cups rock salt, for serving only
  • 1/2 cup grated Parmesan
  • 1/2 cup grated Gruyere

Method

  • Combine 4 tablespoons of the butter, the shallots, garlic, bacon and salt in a large saute pan over medium-high heat.
  • Saute until the shallots are translucent and the bacon is crispy, 6 to 8 minutes.
  • Add the flour and mix well to make a roux.
  • Cook, stirring frequently, until the roux smells nutty, 4 to 5 minutes.
  • Off the heat, deglaze the roux with the liqueur; carefully return the pan to the burner and let the liqueur flame.
  • Add the cream and stir to incorporate.
  • Bring the mixture to a boil, then reduce to a simmer and cook for 5 to 7 minutes.
  • Stir in the baby spinach, nutmeg, black pepper, and red pepper flakes if using; bring back to a boil and once again immediately reduce to a simmer.
  • Cook until the spinach has softened and released its liquid, 4 to 6 minutes.
  • Over medium heat, cook the mixture down to a fondue-like thickness, 6 to 8 minutes.
  • Remove from the heat and reserve to the side.
  • Melt the remaining 4 tablespoons butter in a small saute pan.
  • When melted, remove from the heat and incorporate the breadcrumbs.
  • Reserve to the side.
  • Heat a grill to high heat.
  • Preheat a broiler.
  • Place the oysters on the grill and cook until the shells pop open, about 3 minutes.
  • Remove the oysters to a cutting board and use an oyster knife to pry out the top shells, scraping the knife around the inside of each top shell to loosen the oyster.
  • Once the top shell has been removed, discard it; then use the knife to scrape under the bottom of the oyster to separate it from the bottom shell, leaving the oyster "on the half shell."
  • Spread the rock salt evenly on a baking sheet.
  • Set the oysters, shell down, on the rock salt, pressing the shells into the salt.
  • Spoon some of the baby spinach bacon fondue on top of each oyster; then sprinkle with the Parmesan, Gruyere and, lastly, the buttered breadcrumbs.
  • Broil until the oysters are bubbly and the breadcrumbs toasted, 4 to 5 minutes.
  • Serve immediately.
