I read all the reviews prior to making this dish and share the following: I did add the dash of lemon juice and the balsamic vinegar to the marinade as suggested by one reviewer; I also added two cups of water to the pan when I roasted the lamb. I followed the advise to cover loosely with a foil "tent" and cooked the meat for 20 minutes at 450, turning it down to 350 for 1 hour before putting the heat up to 400, removing the foil and continued to cook for a further 10 - 15 minutes. Roast was medium; I would cook about 10 minutes less at 350 to have a medium rare roast. As also suggested I took all the marinade (cooked with the roast), added a little red wine and red currant jelly. The roast was left to rest for 10 minutes and carved before serving with the sauce poured over. It was absolutely delicious. Sue from Richmond Hill

I too followed the advice of another member and put all the ingredients in the blender. Then I took a pastry brush and "painted" it on the roast. I think this made it much easier to handle. A couple of problems I had. I watched the time very closely but the top of the roast did burn. I beleive that this roast is cooked at too high of a temperature. Normal roasting time is lower temp (325) for 2 1/2 hours. I think that is what I will do next time as my roast would not cook through and I finally ended up lowering the temperature (because the top was burning) and I let it cook another hour. Other than that, I thought the marinade was pretty good.

Taste buds went to heaven! We used a boneless leg of lamb, just under 7lbs. We added 1/4 c Balsamic vinegar, 1/4 c olive oil, and substituted 1 teaspoon lemon juice in place of lemon zest. We slit the roast about an inch deep all over the top and inserted lots of slivers of fresh garlic; marinated for 2 days and sprinkled with regular salt. We placed the lamb on a rack in a covered roasting pan, added cut up potatoes and carrots, baked at 350 for 2 hours, basting every 20 - 30 minutes. We didn't need to place marinade in the middle as others suggested, and also didn't need to add water to the bottom of the pan. We will add at least one cup of water to make gravy in the future. Moist, flavorful dish! The ingredients were a perfect blend.

Very tasty for you lamb lovers! We added a squirt of lemon juice and 1 tbsp. balsalmic vinegar to the marinade. Baked the lamb with the marinade in an oven bag for 2 hours at 300 degrees. It was super tender! Took 2c of the fat drippings and cooked up a sauce with 1c. milk, 1tbsp cornstarch, rosemary twigs, and 1tsp balsalmic vinegar, salt/pepper to taste. A superb sauce/gravy for the lamb. We'll use this recipe again!

My first attempt at lamb. It was fabulous. I did put an aluminum foil tent on the leg of lamb during the first twenty minutes so it would not char..I then roasted it at 350 for 1 and 1/2 hours or until my instant read thermometer read 130 (or medium rare). I added two cups of water to the roasting pan. I read the reviews on this recipe and they were right on. I marinated it for two days, the taste was fantastic. My father in law, who loves lamb, said this was the best lamb he ever had! Another point, worth mentioning, is that I purchased an "American Lamb" versus a "New Zealand Lamb". I read up on lamb in the "Joy Of Cooking" and they stated an American lamb is more tender and sweet then other lambs. I had twelve people for dinner this Easter and they all loved it! Thanks!

made this recipe for easter dinner. my wife didn't want me to do it because it wasn't her mothers recipe. she only eats lamb one day a year and wanted it to be good. she loved it even though it wasn't her mother's lamb. the cooking temperature scared me though, so it roasted to perfection at 350 for 20 minutes a pound, 135 degrees on a meat thermometer. next time it will roast at 300 degrees. it should be more evenly cooked at the lower temperature. the marinade makes for a rich savory gravy. it would be hard to improve on this recipe.

Wow. This was my first roast lamb, and it was spectacular! I made it for Easter dinner and it was perfectly caramelized on the outside, and pink and juicy and tender on the inside, with such a wonderful flavor from the marinade. I used a boneless, tied roast (about 5 lbs.), the lemon juice from the lemon I zested, a splash or two of soy sauce, and a dash of balsamic vinegar. Marinated over night, roasted 20 minutes at 425, then turned down to 350 for remainder of the time. Poured 2 cups of water to the pan, and basted with the leftover marinade a couple of times while cooking. Used a foil "tent" when I noticed it getting too brown. I also used a meat thermometer to check for doneness. Will make this again!!

Great, I cooked mine in an oven bag to enhance the flavour and avoid the marinade burning. Have made this several times.
