Reduce heat to medium, and move the pork chops to one side of the skillet. Add butter, rosemary, thyme, sage, onions, and garlic to other side of skillet; cook, basting pork with butter and drippings, until a thermometer inserted in the thickest portion of meat registers 140°F, 2 to 4 minutes. Remove from heat, the pork will continue to cook to get to 145°F once removed from the heat. Transfer pork chops to a carving board and let rest for 5 minutes. When ready to serve, serve whole or slice against the grain. To serve, spoon the butter-herb mixture over top.
