Pat the scallops dry with paper towels. Season with salt and pepper.
Heat the olive oil in a skillet over medium-high heat. Add the scallops and cook for 2-3 minutes on each side until golden brown. Remove from the skillet and set aside.
In the same skillet, add the butter and garlic. Cook until fragrant, about 1 minute.
Add the lemon juice and zest to the skillet. Stir to combine.
Return the scallops to the skillet and spoon the sauce over them. Cook for another 1-2 minutes until heated through.
Garnish with chopped parsley and serve immediately.
