Warmly spiced, sweet, and savory, this lamb gets roasted until it falls off the bone. Perfect for holidays and celebrations. Adapted from a recipe by Noha Serageldin.
Add all ingredients except lamb to a blender and process until smooth. Set the lamb in a large baking dish, such as a dutch oven. Spread the pureed paste all over the lamb, cover the dish, and refrigerate overnight.
Preheat the oven to 325ºF. Bake the lamb tightly covered for 4 hours, or until tender when tested with a fork. Then remove the lid and cook for another 45 minutes, basting every 15 minutes with the onion and juices (if the pan dries out, add a bit of chicken stock - the lamb will form a very dark crust but the pan should not dry or burn). Let rest at least 20 minutes, serving with any onion gravy from the pan.
