Heat the olive oil in a large skillet over medium-high heat. Once hot, add the scallops in a single layer, making sure not to overcrowd the pan. Season with salt and pepper.
Sear the scallops for about 2-3 minutes on one side until they develop a golden crust. Flip them over and cook for an additional 1-2 minutes until they are opaque and cooked through. Remove the scallops from the skillet and set aside.
In the same skillet, reduce the heat to medium and add the butter. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant.
Stir in the lemon juice and return the scallops to the skillet. Toss gently to coat the scallops in the garlic butter sauce.
Remove from heat, sprinkle with fresh parsley, and serve immediately with lemon wedges on the side.
