Heat 2 tablespoons of extra virgin olive oil in a large skillet set over medium-high heat until shimmering.
2 tablespoons extra-virgin olive oil
Season the scallops with salt and pepper, then add to the skillet, spacing them evenly. Cook without moving for 2-3 minutes, until a deep golden crust forms.
10 to 12 sea scallops, Fine sea salt and ground black pepper
Add the butter and cook for an additional 1-2 minutes, gently turning the scallops and basting with the melted butter, until just opaque in the center. Transfer to a plate.
2 tablespoons unsalted butter
Combine the parsley, garlic, remaining extra virgin olive oil, lemon zest, optional lemon juice, and optional crushed red pepper flakes in a small bowl. Add a pinch of salt and pepper. Stir to form a loose, spoonable mixture.
