Preheat oven to 375°F. Season the pork chops with salt and pepper, and set aside.
In a small bowl, mix together the butter, thyme, and garlic. Set aside.
In a cast iron skillet, heat the olive oil over medium heat. When the skillet is really hot, add the pork chops. Sear until golden, about 2 minutes per side.
Pour the garlic butter mixture over the pork chops. Place the skillet in the oven, and cook until the pork chops reach an internal temperature of 145ºF. It's about 10-12 minutes.
Remove from the oven. Using a spoon, pour some of the butter sauce left in the skillet onto the pork chops before serving.
