Start by ensuring the scallops are completely dry, as this will help them sear nicely. Season them lightly with salt and pepper on both sides.
In a large skillet, melt 2 tablespoons of butter over medium-high heat. Once the butter is sizzling and foamy, add the scallops to the pan, making sure they are not overcrowded.
Cook the scallops for 2-3 minutes without moving them until they form a golden crust. Flip them carefully and cook for another 2-3 minutes on the other side until they are opaque and cooked through. Transfer the scallops to a plate and cover to keep warm.
In the same skillet, add the remaining 2 tablespoons of butter and the minced garlic. Sauté for about 1 minute until the garlic is fragrant (be careful not to burn it).
Add the lemon juice and zest to the skillet, stirring to combine. Let the sauce simmer for about 1-2 minutes to infuse the flavors.
Return the scallops to the skillet and gently coat them in the lemon garlic butter sauce.
Remove the skillet from heat and stir in the chopped parsley for a fresh touch.
Serve the scallops warm, drizzled with the lemon garlic butter and garnish with lemon wedges on the side.
