Heat olive oil in a large skillet over medium-high heat. Once hot, add the scallops, making sure not to overcrowd the pan. Season with salt and pepper.
Sear the scallops for about 2-3 minutes on one side until they develop a golden crust. Flip and cook for an additional 1-2 minutes until opaque. Remove scallops from the skillet and set aside.
In the same skillet, reduce the heat to medium and add the butter. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant.
Stir in the lemon juice and zest, scraping any browned bits from the bottom of the pan. Cook for an additional minute to combine flavors.
Return the scallops to the skillet, tossing gently to coat them in the sauce. Cook for another minute to heat through.
Serve immediately, garnished with chopped parsley.
