Step 1Heat oil in 10-inch nonstick skillet over medium-high heat. When very hot, add scallops in single layer without overcrowding. Cook until well browned on 1 side, about 2 minutes. Shake pan to avoid sticking. Use tongs to turn, season with salt and pepper and continue to cook until browned and slightly firm to touch, about 2 minutes. Do not overcook. Use tongs to transfer scallops to warm dish.
Step 2Remove skillet from heat to cool slightly. Combine zest, garlic and juice in small bowl. Add to slightly cooled skillet. Cook over medium heat until hot, about 5 seconds, scraping up bits from skillet. Stir in butter until melted. Season with salt and pepper. Drizzle over scallops. Garnish with dill. Serve hot over rice.
