01 - Preheat the oven to 450°F.
02 - Melt 2 tablespoons of butter in a medium skillet over medium heat. Add the finely minced shallot and garlic, then sauté until fragrant and translucent, approximately 2 minutes.
03 - Incorporate the chopped baby spinach and cook, stirring frequently, until it has wilted, about 2 minutes.
04 - Stir in the chopped parsley and chives. Deglaze the pan with Pernod or dry white wine, cooking until most of the liquid has evaporated, about 1 to 2 minutes. Season with salt and freshly ground black pepper to taste. Remove the skillet from heat and allow the mixture to cool slightly.
05 - In a small bowl, combine the panko breadcrumbs, grated Parmesan cheese, and 1 tablespoon of melted unsalted butter.
06 - Arrange the shucked oysters on a baking sheet or in a baking dish. Line the dish with rock salt or crumpled aluminum foil to stabilize the oysters.
07 - Spoon a generous portion of the prepared spinach mixture over each oyster.
08 - Evenly sprinkle the breadcrumb mixture over the top of each oyster.
09 - Bake for 8 to 10 minutes, or until the topping is golden brown and crispy.
10 - Serve immediately, garnished with fresh lemon wedges.
