The scallops should be patted dry thoroughly with paper towels. This is done to secure that golden-brown crust that is beautiful. Lightly sprinkle both sides with salt, pepper, and smoked paprika.
Bring your cast-iron skillet to a hot location of medium-high heat. Add the olive oil and the butter (2 tablespoons). When the scallops are put in the pan, they should sizzle.
Thin slices of scallops should be put on one layer, and they must not be crowded together. Cook approximately 2 minutes on each side, by which time a golden crust should have developed. Take out the scallops and place them on a hot dish.
Add garlic to the same skillet and sauté it for 30 seconds. Add the white wine (or broth) and scrape the bottom of it for flavor.
Reduce the heat to low. Add in the remaining butter, lemon juice, and zest. Simmer gently with the purpose of reaching a slight thickening.
Put the scallops back in the pan, pour the sauce over them, and allow them to heat in the sauce for 1 minute.
Parsley and serve hot, preferably with crusty bread, mashed potatoes, or a fresh salad.
