Pat scallops completely dry. Moisture is the enemy of a good sear. Season with salt and pepper on both sides.
Heat olive oil in a skillet over medium-high heat until shimmering. Add scallops and sear 1–2 minutes per side until golden. Do not overcrowd the pan. Flip once and resist the urge to fiddle.
Remove scallops to a plate. In the same pan, add garlic and sauté 30 seconds until fragrant. Don’t burn the garlic, or you’ll ruin the vibe.
Deglaze with white wine (or broth) and scrape up any browned bits. Add lemon zest, juice, tomatoes, olives, and capers. Simmer 2–3 minutes to meld flavors.
Return scallops to the pan. Stir in butter until glossy. Sprinkle with chopped parsley or basil and a final pinch of salt if needed. Serve hot.
