Step 1

Take the leg of lamb out of the refrigerator and leave in room temperature for about 1 hour. In the meantime, prepare the remaining ingredients and make the lamb rub.

Step 2

To make the rub, in a food processor, combine the rub ingredients. Blend until smooth. Set aside (or in the fridge, if preparing in advance).

Step 3

When ready, pat the lamb dry and make a few slits on both sides. Season with salt and pepper.

Step 4

Turn the oven on broil. Place the leg of lamb on a wire rack; place the rack directly on the top oven rack so that it's only a few inches away from the broiler element. Broil for 5-7 minutes on each side or until the leg of lamb is nicely seared. Remove from the oven, then adjust the oven temperature to 325 degrees F.

Step 5

When the lamb is cool enough to handle, insert the garlic slices in the slits you made earlier. Now cover the leg of lamb on all sides with the wet rub and place it in the middle of a roasting pan with an inside rack (like this one-->affiliate). Add two cups of water to the bottom of the roasting pan.

Step 6

Season the potato and onion wedges with the paprika, garlic powder and a little salt, then add them to the pan on either side of the lamb.

Step 7

Now tent a large piece of foil over the roasting pan (make sure it does not touch the lamb) then place the pan on the middle rack of the 325 degrees F heated-oven. Roast covered for about 1 hour. Remove the foil and return the roasting pan to the oven for another 10 to 15 minutes or until the lamb temperature registers 130 degrees F for medium-rare.

Step 8

Remove the pan from the oven and let the leg of lamb rest for about 15 minutes before serving (the lamb will continue to cook and it's internal temperature will continue to rise.

Step 9

Place the lamb and potatoes in a large serving platter over a bed of Lebanese rice, if you choose to. Garnish with parsley.

Step 10

Or, you may carve the lamb first, then arrange the sliced lamb with the potatoes over the rice. Enjoy!
