Pat the pork chops dry and season all over with the salt and pepper.
Heat the oil in a large skillet over high heat. Once the oil is glistening, working in batches, add the pork chops and cook, undisturbed, for 4 minutes, then flip and continue cooking for another 4 minutes. Continue cooking this way, flipping the pork, until the internal temperature of the pork reads 135°F on an instant-read thermometer, 8 to 10 minutes total. Transfer the pork chops to a serving platter and cover with foil to keep warm. Repeat with remaining pork chops.
Reduce the heat under the skillet to medium low and add the butter, garlic, and thyme. Once the butter has melted, return the cooked pork chops to the pan. Cook, continuously spooning the garlic thyme butter over the pork chops, until the internal temperature of the pork reads 145°F on an instant-read thermometer, 1-2 minutes per side.
