01 - Pat scallops thoroughly 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 shimmering hot.
03 - Arrange scallops in a single layer without overcrowding. Sear undisturbed for 2 minutes until golden-brown crust forms, then flip and cook 1-2 minutes more. Transfer to plate, cover loosely with foil.
04 - Reduce heat to medium. Add remaining butter and minced garlic to skillet. Sauté 30 seconds until fragrant but not browned.
05 - Stir in lemon juice and zest, scraping up browned bits from pan bottom. Simmer 1 minute until slightly reduced.
06 - Return scallops to pan. Spoon sauce over scallops and cook 1 minute to heat through. Garnish with parsley and serve immediately.
