Pat the scallops dry with a paper towel to ensure they sear well. Season both sides with salt and pepper.
Heat a large skillet over medium-high heat.
Add the unsalted butter to the skillet. Once the butter has melted and is sizzling, add the scallops in a single layer, being careful not to overcrowd the pan.
Sear the scallops for about 2-3 minutes on each side, or until they develop a golden-brown crust.
Do not move them while they are searing to allow a good crust to form. Once seared, remove the scallops from the skillet and set them aside on a plate.
In the same skillet, add the minced garlic to the remaining butter. Sauté for about 1 minute, or until the garlic becomes fragrant but not burnt.
Add the lemon juice to the skillet and stir, scraping up any bits stuck to the bottom of the pan. Let the sauce simmer for 1-2 minutes to slightly reduce.
Return the scallops to the skillet, tossing them gently in the lemon-garlic butter sauce.
Sprinkle the chopped fresh parsley over the scallops. Serve immediately, with any remaining sauce drizzled over the top.
