Oven-Roasted Boneless Leg of Lamb

"I purchased a leg of lamb roast from the store recently but had no idea on how I'd cook it. After reading ideas here on Allrecipes, I came up with my own marinade. While I made this in a conventional oven, it could also be made in a slow cooker on the slow setting for 7 to 8 hours time). Hope it's a hit! There was enough marinade left that I threw it over some chicken tenders for tomorrow's dinner."

Ingredients

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Whisk the olive oil, lemon juice, lime juice, minced garlic, mint, oregano, marjoram, thyme, rosemary, nutmeg, cinnamon, ginger, white pepper and salt in a bowl to make the marinade.

  2. Pat the lamb dry and place it in a dish or resealable bag. Pour the marinade over, turn to coat, cover and refrigerate for at least 2 hours or overnight.

  3. Preheat the oven to 350°F (177°C). Lightly coat a roasting pan with cooking spray. Remove the lamb from the fridge about 30 minutes before roasting.

  4. If using, toss the potato and carrot chunks with the vegetable oil and arrange them around the edges of the roasting pan.

  5. Set the lamb in the center of the pan and spoon the remaining marinade over it. Roast for about 75 to 90 minutes, basting with pan juices, until the thickest part reads at least 145°F (63°C).

  6. Let the lamb rest for 3 minutes, then slice it thinly against the grain and serve with the roasted vegetables and pan juices.
