Start by patting the scallops dry with paper towels. This step is crucial for getting that beautiful golden crust. Season both sides with salt and freshly ground black pepper.
In a large skillet, heat the vegetable oil over medium-high heat. You want the oil hot enough that it shimmers but doesn’t smoke.
Carefully add the scallops to the hot skillet, making sure they are spaced apart to allow even cooking. Sear for about 2-3 minutes without moving them, until a golden crust forms.
Using a spatula, gently flip the scallops over. Add 2 tablespoons of butter to the skillet and let it melt, spooning the melted butter over the scallops as they cook. Sear for another 2-3 minutes, until cooked through and opaque.
Once the scallops are done, remove them from the skillet and set aside on a plate. In the same skillet, reduce the heat to medium and add the minced shallot. Sauté for about 1 minute until fragrant. Then, add the 4 pieces of butter, minced parsley, thyme, lemon juice, and a pinch of salt and pepper. Stir until the butter is melted and the sauce is well combined.
Return the scallops to the skillet, gently tossing them in the lemon butter sauce to coat. Serve immediately on a warm plate, drizzled with any remaining sauce.
