Pat scallops completely dry with paper towels — this is the most important step. Moisture on the surface causes steaming instead of browning, killing your crust. If frozen, thaw overnight on a towel in the fridge, then pat dry again right before cooking. Peel off the small, firm side muscle if attached. Season both flat sides lightly with salt just before cooking. Have everything else ready before the pan goes on — scallops cook fast and need your full attention.

Heat a large skillet over medium-high heat. Add about 2 tablespoons of olive oil or a butter-oil combo and let it get very hot and shimmering before the scallops go in. A cool pan means sticking and no crust. Place scallops flat-side down one at a time, leaving plenty of space between them. If the pan is too small, cook in batches. Do not move them. Cook undisturbed on the first side until deeply golden-brown and releasing easily, about 1.5 to 4 minutes depending on size. If a scallop resists when you try to flip it, give it another 30 seconds. Flip once and cook the second side for 1.5 to 2 minutes, until just firm and opaque through the center. Target internal temperature is 130°F. Total cook time is roughly 3 to 5 minutes.

Scallops are done when deeply golden-brown on both flat sides, just firm to a gentle press, and opaque through the center. Stop cooking at this point — they turn rubbery fast. Use 130°F internal temp if unsure. Remove from pan immediately. Let rest one minute off heat for carry-over to finish. For a quick pan sauce, add lemon juice, white wine, or stock to the butter in the pan, cook over medium heat 2–3 minutes scraping up browned bits, then swirl in 1–2 tablespoons cold cubed butter off heat to emulsify. Add fresh herbs if desired and pour over scallops.
