I was inspired to roast a leg of lamb after Ioannis
Michanetzis (a fan of startcooking.com) sent me his recipe for a marinated, roasted leg of lamb.
Ioannis, an Officer in the Greek Navy,
is currently a ship’s captain, with aspirations to have a cooking site
specializing in healthy and unique Mediterranean Dishes.
Ioannis’s original recipe was a bit more involved than
the recipe I’m doing here, but I would like to thank him for giving me the
opportunity (and permission) to adapt one of his specialties for startcooking.com readers.

At my grocery store, there were two choices of leg of lamb
being offered. Both were from Australia.

I am going to demonstrate how to cook the smaller 5-pound boneless roast shown on the top in the picture above. The larger 9-pound roast on the bottom is a “bone-in” cut. For beginner cooks, the smaller
boneless roast is easier to carve. Besides, it just fit into my 15-inch long
roasting pan, and my larger roasting pan is not as photogenic!
The steps involved in making this boneless leg of lamb are:
- Make a “spice-rub” with garlic, thyme, rosemary, oregano and black
pepper. - Rub it all over the roast.
- Put the roast in a plastic bag
- Pour fresh lemon juice, olive oil and wine over the
roast in the bag - Put the bag in the refrigerator to marinate for several hours or overnight.
- Remove the lamb from the bag and roast it in the oven.
The Marinade
(Marinate is the verb, and marinade is the noun. So, you
marinate the lamb with a marinade. Got it? Who’s on first?)
Step 1. First make a spice-rub by measuring out:
- 3
cloves of garlic, crushed - 2
teaspoons of dry oregano - 2
teaspoons of dry thyme - 2
teaspoons of dry rosemary - 1/4
teaspoon of fresh ground black pepper

Put these ingredients into a small bowl…

…and mix everything together

Now, for the liquid part of the marinade, measure out:
- 1/2
cup (4 oz.) of olive oil - 1/2
cup (4 oz.) of lemon juice, fresh squeezed - 2 cups (16 oz.)
of dry red wine

My wine merchant suggested a very reasonably priced Merlot
() for the dry red wine.
The Boneless Leg of
Lamb
(FYI – It’s just the hind legs that are used for “leg of
lamb”)
Rather than working directly on the counter top, I set the
lamb down on some paper towels on a baking sheet. This is more sanitary.
Cut the plastic outer wrapping off the lamb, making sure not
to cut through the netting as well. (If you bought your lamb at a butcher shop, it may well be
hand-tied with string instead of netting.) The
netting (or string) holds the lamb together in that nice shape. Do not remove it until after the lamb is roasted.

Step 2. Rub the garlic dry-rub spice mixture all over the lamb.

Step 3. Put the lamb in a large plastic bag and set it on a dish. I used a two gallon sized zip-lock bag. (You
need the dish just in case the bag leaks when you put it in your refrigerator.
You wouldn’t want the marinade to spill all over the inside of your
refrigerator!)

Step 4. Pour the lemon juice, olive oil and red wine over the lamb
(in the bag.)

Squeeze out as much of the air as possible from the bag, and
seal it closed. As a precaution against
the bag leaking, wrap a second bag around the marinating lamb.

Step 5. Set the bag in a dish and let the lamb marinate in the
refrigerator for several hours or overnight -up to 24 hours.
Step 6. Roasting the Boneless
Leg of Lamb
Remove the lamb from the refrigerator at least 1 hour before
cooking it.
Preheat the oven to 450 F. degrees.
(
450º F = 230º C = gas mark 9)
Snip the corner of the bag and squeeze the marinade out into
the sink. It will no longer be usable.

Pat the lamb dry with paper towels.

Put 2 teaspoons of salt and 3/4 teaspoons of freshly ground
pepper into a dish. Season the entire
lamb with the salt and pepper. (You put the salt and pepper into a separate dish first
for sanitary reasons. You would not want to be going back and forth between
touching the raw lamb and your main salt and pepper holders.)

Place the lamb on a roasting rack in a roasting pan.

Insert an oven-safe meat thermometer into the thickest part
of the boneless leg of lamb.
(I strongly recommend using an oven-proof meat thermometer
for roasting a leg of lamb. This should allow you to peek through the window of
your oven door without opening the door and changing the internal temperature
of the oven. Every time you open the oven door, it takes a good ten minutes for
the temperature to get back to its original setting)

Set the lamb into the 450-degree oven and roast for 20 minutes.
(
450º F = 230º C = gas mark 9)

After the 20 minutes, lower the temperature to 325º Fdegrees (
325º F = 165º C = gas mark 3-very moderate) and continue cooking
the lamb until the internal temperature is to your liking.

*Most people avoid cooking lamb to “well done”. It will be tough and dry.
There are several factors that will affect the cooking time:
- The
shape of the roast - The
internal temperature when you first put it in the oven - Bone-in
roast will require extra cooking time - Fluctuations
in temperature of your own oven.
My 5 pound Leg of Lamb was removed from the oven when the internal temperature of the Lamb reached 140 F. degrees – medium rare.
It took a total of 1 and 1/2 hours to cook, which was considerably less time than what the USDA guidelines had recommended.
This is why a meat thermometer is absolutely essential when
you are cooking a roast.
When the meat is cooked, remove it from the oven and let it
rest for 10 minutes. The temperature will increase by about 5 degrees while the roast is resting out of the oven.
With a pair of kitchen scissors cut through the netting (or string)….

…..and remove it completely.

Slice the lamb into 1/2 inch thick slices across the
grain. (Here and here are very some very good pictures that show how to carve a bone-in Leg of Lamb.)
I roasted some carrots and small red potatoes separately….

….and served them with this Boneless Leg of Lamb.

Enjoy!
