Heat the ghee or olive oil in a cast iron skillet over medium-high heat. Once hot, arrange the pork chops in a single layer. Sear the pork chops until they’re golden brown on the bottom, about 5-7 minutes. Turn and cook on the other side until golden brown, about 5 minutes longer. Keep cooking, flipping and turning the chops as needed, until an instant-read thermometer inserted in the thickest part reads 140˚F (60˚C)—the cooking time will depend on the thickness of the chops. Transfer the chops to a plate and tent lightly with foil to keep warm (the temperature will climb to 145˚F as it rests).
