Prep the Scallops: Gently remove the small side-muscle from the scallops if it's still attached. Pat the scallops completely dry with paper towels. Season both sides with salt and pepper.
Heat the Pan: Heat a large skillet (stainless steel or cast iron is best) over high heat. Add the ghee or oil. The pan is ready when the oil is shimmering and just beginning to smoke.
Sear the Scallops (Side 1): Carefully place the scallops in the hot pan in a single layer, ensuring they are not touching. Cook for 90 seconds, without moving them, until a deep golden-brown crust has formed on the bottom.
Flip and Sear (Side 2): Use tongs to flip each scallop. Cook for another 60-90 seconds on the second side until opaque. Immediately remove the scallops from the pan and set them on a plate. Do not overcook.
Make the Sauce: Reduce the heat to medium-low. Add the minced garlic to the pan and cook for 30 seconds until fragrant. Pour in the white wine or broth to deglaze, scraping up any browned bits with a spoon.
Finish & Serve: Let the wine bubble for a minute. Remove the pan from the heat. Stir in the butter, lemon juice, and fresh parsley. Pour the sauce over the seared scallops and serve immediately.
