Pat scallops dry with paper towels and season with salt and pepper.
Heat olive oil in a large skillet over medium-high heat.
Add scallops to the skillet and sear for 2-3 minutes on each side, until golden and cooked through.
Remove scallops from skillet and set aside.
In the same skillet, melt butter over medium heat. Add garlic and sauté until fragrant, about 1 minute.
Stir in lemon juice, then return scallops to the skillet. Cook for 1-2 minutes, basting scallops with the sauce.
