To prepare a stuffed lobster tails appetizers recipe, first you need to prepare the lobster. First, you'll need the following ingredients: 2 tbsp. kosher salt, 2 tablespoons melted butter, 1/2 cup shredded parmesan cheese, 1 teaspoon each thyme and dill weed, and 1/4 teaspoon pepper. Mix the ingredients together with your hands until they're evenly combined. Next, heat the butter over medium-high heat until it's shimmering. Then, add the flour and mix until the mixture is light and fluffy, about 1 minute. Add the scallions and cook, stirring, for an additional 1 to 2 minutes. Remove the pan from the heat and stir in the parsley. Scoop the filling into the shells of your lobsters and stuff them with the rest of the stuffing mixture. Cover the bowl with plastic wrap and refrigerate for at least 1 hour or overnight.
