Heat a large skillet over medium-high heat. When the pan is hot, add the oil.
Pat the scallops very dry with paper towels, then season on one side with salt and pepper RIGHT before cooking and no sooner.
Carefully place the scallops in the hot oil, seasoned side down, and let cook, undisturbed for about 2 minutes or until nicely browned around the bottom. Season the other side while they cook.
The scallops should easily release from the pan once they brown. Flip, lower the heat, then add the butter and aromatics if using.
Tilt the pan to the side and use a spoon to baste the scallops with the melted butter for about 30 seconds to 1 minute depending on their size and desired level of doneness.
The scallops are done when they look mostly opaque throughout. I prefer my scallops medium to medium well so I remove them when they are still a bit translucent in the center.
Remove the scallops from the pan and serve immediately with lemons on the side.
