Roast Leg of Lamb
1/2 cup orange juice
1 cup white wine
3 cloves garlic, minced
2 teaspoons of fresh thyme or 1 teaspoon of dried thyme
2 Tbsp of fresh chopped rosemary or 1 Tbsp of dried rosemary
1/4 teaspoon of fresh ground pepper
Blend marinade ingredients in a blender, just a few pulses until well mixed.
1 (6-pound) leg of lamb, bone-in or boneless. If boneless, the leg should be tied up with kitchen string by butcher.
Salt and freshly ground black pepper
1 Place lamb and marinade into a plastic bag. Squeeze out as much of the air as possible from the bag and seal. Wrap again with another plastic bag to ensure that the marinating lamb doesn’t leak. Marinate for several hours, or overnight, in the refrigerator. Remove the lamb, still in its marinade bag, from the refrigerator at least an hour (preferably two hours) before putting in the oven to help bring the lamb closer to room temperature before roasting.
2 Preheat oven to 425°F. Arrange two racks in the oven – a middle rack to hold the lamb, and a lower rack to hold a roasting pan with which to catch the drippings. Note that this arrangement of racks and pans, with the roast sitting directly on the oven rack, will create a natural convection of heat in the oven, causing the roast to cook more quickly than if cooked the traditional method in a rack in a roasting pan.
3 Remove the lamb roast from its marinade bag (you may want to temporarily place lamb in another roasting pan, just to make it less messy to work with.) Pat dry the marinade off the lamb with paper towels. Generously salt and pepper all sides of the roast. Arrange the roast fattiest side up, so while the lamb is cooking the fat will melt into the meat. Insert an oven-proof meat thermometer into the thickest part of the roast, not touching the bone if your roast is bone-in. Place the roast directly on middle rack of the oven, with a roasting pan on a separate rack a rung lower, to catch the drippings. You may also want to put some water in the bottom roasting pan, so that the drippings fall into the water instead of burning in the hot pan and smoking up your kitchen.
4 Roast at 425°F for 20 minutes. Then reduce the heat to 300°F and roast an additional 40 minutes (for a 6 pound boneless roast) to an hour (for a 6 pound bone-in roast). If you are cooking a roast bone-in, the bone will act as an insulator and will require a longer cooking time than a boneless roast. In general estimate 10-13 minutes per pound for total cooking time (for rare), including that first 20 minutes at high heat. (Assuming you let the roast sit out for an hour or two before putting it in the oven. If it’s right out of the fridge, it will take longer to cook.)
Note that the method of cooking directly on the oven rack will mimic a convection oven and the cooking time/oven temp needed will be less than you would need if you cooked the roast on a rack in a roasting pan. If you are cooking the roast in a roasting pan, rack or not, start the roast at 450°F and then reduce the heat to 325°F. Also, the shape of the roast will have an impact on the cooking time. Our roast was rather long and thin, so it cooked up fairly quickly. A thicker roast may take longer than expected.
So, use a meat thermometer!
About 20 minutes before you expect the roast to be done, start checking the meat thermometer. Note that every time you open the oven door, you’ll need 10 minutes or so to bring the oven back up to temperature, thus slowing down the cooking process. So, don’t check too often. Remove from the oven anywhere from 125°F to 135°F for medium rare. Lamb should never be cooked until well done or it will be too dry. Let stand for 25-30 minutes before carving. Cut away the kitchen string and slice with a sharp carving knife, 1/2 inch thick slices, against the grain of the meat.
5 While the roast is resting, use a metal spatula to scrape up the drippings in the roasting pan. Use the drippings to make a gravy, or use just the drippings themselves to serve with the lamb.
Serve with some homemade mint jelly for an added treat.
Yield: Serves 8 to 10.
