To prepare a stuffed crown of lamb with winter green beans recipe, you'll first need to prepare the filling. Place the lamb in the roasting pan and season it with salt and pepper. Cover the meat with foil and let it rest for at least 30 minutes. Then, place the foil over the top of the stuffing and cook it over medium-high heat until it's browned on all sides, about 10 to 15 minutes, or until the internal temperature reaches 160?F (71?C). Remove it from the oven and allow it to rest, covered, for 15 to 20 minutes before serving.
