Step 1

Preheat the oven to 375 degrees F.

Step 2

In a bowl, combine 1 stick of the butter with the breadcrumbs, the lemon rind, 1/4 cup of the parsley, the oregano, 1 1/2 tablespoons of the garlic, the chili flakes, 1/4 cup of the sherry, the nutmeg, the salt, and the pepper, whisking well to combine everything into a compound butter.

Step 3

Heat the remaining butter on medium-high heat in a skillet.

Step 4

Add the shrimp, the scallions, the remaining parsley, the remaining garlic, the remaining sherry, the salt, and the pepper to the melted butter.

Step 5

Mix the shrimp in the skillet well and cook until they are light pink in color and about to curl up, about 1-2 minutes.

Step 6

Transfer the shrimp and the sauce it cooked into in a casserole dish.

Step 7

Top each of the shrimp with a generous dollop of the compound butter mixture.

Step 8

Bake until the top becomes golden brown and the shrimp are cooked through to 145 degrees F, about 20-25 minutes.
