Trim any excess fat from the lamb chops, keeping a bit for flavor. Lightly coat each chop with olive oil.
Generously season the lamb with minced garlic, fresh rosemary, salt, and freshly ground black pepper. Arrange the seasoned chops in a cast iron skillet.
Place the skillet in the preheated oven and roast the lamb chops for about 8 to 10 minutes, or until they reach an internal temperature of at least 140°F (60°C) for a medium-well finish.
Once cooked, take the skillet out of the oven and cover the chops with aluminum foil. Allow them to rest for 8 to 10 minutes before serving.
Enjoy the lamb chops accompanied by a side of mint jelly.
