Prepare the Scallops
Pat scallops thoroughly dry with paper towels. If needed, wipe with a damp towel instead of rinsing. Remove the small side muscle. Season both sides lightly with salt and pepper.
Heat the Skillet
Preheat a stainless steel or cast-iron skillet over medium-high heat. Allow it to heat fully so scallops sear instead of steam.
Sear the Scallops
Add 1 tablespoon of butter to the hot pan. When the butter is hot and shimmering, place scallops in a single layer.
Cook 2–3 minutes per side, flipping once, until:
A deep golden crust forms
Centers are opaque
Scallops feel lightly firm to the touch
Make the Garlic Butter
Transfer scallops to a plate. Reduce heat to low–medium. Add remaining butter and garlic. Stir gently for 30 seconds until fragrant. Add lemon juice and stir.
Finish and Serve
Return scallops to the pan. Spoon the garlic butter over them. Sprinkle with parsley and serve immediately.
