01 - Pat the scallops completely dry with paper towels. Season both sides generously with salt and pepper.
02 - Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat until hot and shimmering.
03 - Add scallops in a single layer without crowding the pan. Sear undisturbed for 2 minutes until a golden crust forms, then flip and sear for 1 to 2 minutes. Transfer to a plate and cover loosely with foil.
04 - Reduce heat to medium. Add remaining 1 tablespoon butter and minced garlic to the skillet. Sauté for 30 seconds until fragrant.
05 - Stir in lemon juice and zest, scraping up any browned bits from the pan bottom. Simmer for 1 minute to meld flavors.
06 - Return scallops to the pan and spoon sauce over them. Cook for 1 minute to heat through. Sprinkle with chopped parsley and serve immediately.
