  1. Allow the leg of lamb to rest at room temperature for 1 hour before cooking.
  2. Preheat an oven to 400 degrees F (200 degrees C). Place the oven rack in the lower third of the oven.
  3. Whisk the garlic, pepper, red pepper flakes, bay leaf, rosemary, 1/2 cup olive oil, vinegar, and honey together in a small bowl. Rub the mixture over the lamb, then season with 2 tablespoons coarse salt. Set aside. Place carrots, potatoes, beet, yam, and turnips in a large roasting pan. Toss with 2 tablespoons olive oil and a pinch of salt. Arrange the seasoned leg of lamb on top of the vegetables.
  4. Roast the lamb in the preheated oven for 20 minutes, then reduce oven temperature to 325 degrees F (165 degrees C). Continue roasting to your desired degree of doneness, about 90 minutes more for medium-rare. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C).
  5. Allow the leg of lamb on a cutting board, tented with aluminum foil, for 30 minutes before carving. Place the vegetables on a serving platter and cover with aluminum foil to keep warm until ready to serve.

  • Cook's Note:
  • Reserve any rub you didn't use in preparing the lamb, and use it the next day to drizzle on lettuce on sandwiches made with the leftover lamb.

I prepared this for supper last night and my husband and I loved it, it is a definite keeper. I enjoy trying new recipes that contain winter vegies and I couldn't have been more pleased with this. The flavors of the rub meld so wonderfully together and had a nice little bite to it. I will definitely be making this one for the extended family.

Root vegies don't have much flavor

This tasted really good, but I cut the root vegetables too large and they remained firm after I roasted them. I made the following changes: I marinated the lamb leg for 4 hours before roasting, I poured the excess marinade into the root vegetables and mixed them until they were all coated. I left the lamb in a bit longer with the oven off, it was medium done and more rare on the bottom. Next time I would try putting the leg on its own baking dish half-way through and covering the vegetables with a lid so that they would soften. I would also cut the vegetables into smaller pieces.

We are military family and live in Germany and could not get a leg of lamb, so I substituted a 4lb Ribeye Roast. Allowed the roast to marinate while I boiled the vegetables for 20 minutes, added an extra sweet potato, (no yams or white potatoes in the house at the moment). Only put in 2 parsnips but added 2 cups of brussel sprouts to give it color. Also added an onion when boiling to add flavor and topped off with some mushrooms as I was putting it into the oven. Everyone thought it was fabulous.

made this yesterday and it was the best lamb I've ever eaten. the roast was sooo tender. I mixed the leftover rub into the veggies in the roaster since I was afraid there wouldnt be enough flavour on them. I made several small changes to the recipe; I used .5 tsp of cayenne pepper rather than the red pepper flakes (.33 would have been plenty), I used dry rosemary since I couldnt get any fresh, I cut the veggies into cubes rather than wedges, I reduced the heat from 400 after 20 minutes to 350 and stirred every 25 minutes or so, and I let it sit for 10 minutes at the end. I was delighted with the outcome! I'll definately be cooking this again! Deliciousness!

Have made this twice now and love it. There's never any lamb leftover. Great flavor with lamb.
