We eat this every year for Easter. It is a family favorite. I normally cook half of a leg. If you cook a whole leg of lamb, double the recipe. You need to start this recipe at least 24 hours before cooking. It needs to marinade at least overnight.

Recipe Instructions
Step 1
Mix yogurt, 4 sprigs of rosemary, 1/2 bunch of parsley, smashed garlic, and zest of 1 1/2 lemons in a large bowl. Place the leg of lamb in the yogurt mixture and stir to coat. Cover and refrigerate for 24 to 48 hours.
Step 2
The next day, preheat an oven to 400 degrees F (200 degrees C). Spread onions on the bottom of a roasting pan. Remove lamb from the marinade, rinse and pat dry. Set aside.
Step 3
Place olive oil, salt, pepper, 4 sprigs of rosemary, 1/2 bunch of parsley, 1/2 head of garlic, and zest of 1 1/2 lemons in a food processor. Process until the mixture becomes a smooth paste. Rub leg of lamb with the paste, and place on top of the onions in the roasting pan.
Step 4
Bake in the preheated oven for 20 minutes, then reduce the temperature to 325 degrees F (165 degrees C). Continue baking until desired doneness, 40 to 50 minutes for medium. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
