01 - Pat the scallops thoroughly dry with paper towels. Season both sides generously with salt and pepper, ensuring even coverage.
02 - Combine 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Heat until the butter bubbles and oil shimmers, about 1 minute.
03 - Arrange scallops in a single layer without overcrowding the pan. Cook undisturbed for exactly 2 minutes until a deep golden-brown crust forms on the bottom.
04 - Flip each scallop using tongs. Sear the second side for 1 to 2 minutes until just opaque throughout. Transfer scallops to a plate and cover loosely with foil.
05 - Reduce heat to medium. Add remaining olive oil and butter to the skillet. Add minced garlic and sauté for 30 seconds until fragrant but not browned.
06 - Stir in lemon zest, lemon juice, and red pepper flakes if using. Simmer for 1 minute, scraping up any browned bits from the bottom of the pan.
07 - Return scallops to the pan, spooning the sauce over each one. Cook for 1 minute to warm through. Sprinkle with fresh parsley and serve immediately.
08 - Serve with crusty bread to soak up the sauce, over angel hair pasta, or alongside creamy risotto for a complete meal.
