Preheat the oven to 400°F. Dab the meat with a paper towel.
Season both sides of the chops with salt and pepper.
Heat a cast iron skillet or oven-safe pan over medium-high heat. Add the olive oil and 1 tablespoon of butter. Once the butter has melted and is sizzling, add the chops.
Sear the meat for about 2-3 minutes on each side, or until it develops a golden-brown crust.
Reduce the heat to medium-low and add the remaining 5 tablespoons of butter, minced garlic, and finely chopped rosemary to the skillet. As the butter melts, tilt the skillet and spoon the garlic-rosemary butter over the chops for about 1-2 minutes.
Transfer the skillet to the preheated oven. Bake for 3-5 minutes, or until an internal temperature of 145°F is reached with a meat thermometer.
Remove the chops from the oven and rest for 5 minutes before serving.
Serve hot, spooning the garlic-rosemary butter from the skillet over the top. Garnish with rosemary sprigs if desired.
