Orange Roasted Lamb

    1 hour 30 minutes

    Roast lamb and potatoes is a wonderfully hearty and satisfying dish, particularly in winter. This recipe has a secret ingredient - orange juice - that really brings out the flavour of the lamb.

    Serves: 4 

    • 1 large orange, juiced
    • 3 tablespoons French mustard
    • 3 tablespoons olive oil
    • 4 teaspoons dried oregano
    • 1 pinch salt and pepper to taste
    • 10 potatoes, peeled and cut into 5cm pieces
    • 1 (1 1/2 kg) half leg of lamb, bone-in
    • 5 cloves garlic

    Preparation:30min  ›  Cook:1hour  ›  Ready in:1hour30min 

    1. Preheat oven to 190 degrees C.
    2. In large bowl whisk together the orange juice, mustard, olive oil, oregano, salt and pepper. Stir the potatoes into the bowl to coat with orange juice mixture. Remove potatoes with a slotted spoon and place them into a large roasting pan.
    3. Cut slits into the lamb meat and stuff the garlic cloves into the slits. Rub remaining orange juice mixture from bowl all over the lamb and place the lamb on top of the potatoes in the roasting pan. If there's any remaining orange juice mixture pour it over the lamb.
    4. Roast in the preheated oven until the potatoes are tender and the lamb is cooked to medium, about 1 hour. Check every 20 to 30 minutes while roasting, and add a bit of hot water if you find the potatoes are drying out. If the lamb finishes cooking before the potatoes remove the lamb to a cutting board or serving platter and cover with foil while the potatoes continue to bake in the oven.

    I tried this upon the recommendation of a friend. while I am not a big fan of lamb, this was very good!! I used a roast instead of leg of lamb. Wish I had marinated for a bit longer. The roast came out tender and moist. I did add a little cayenne pepper for some heat. I also took the advice of the author and used dijon mustard. Will try this again!  -  09 Aug 2010  (Review from Allrecipes USA and Canada)
