Lamb

Mashed Potatoes

Method

Lamb

  1. 1

    Prepare the Marinade

    In a bowl, mix together minced garlic, chopped fresh rosemary, olive oil, salt, black pepper, and lemon juice to create a marinade.

  2. 2

    Marinate the Lamb

    Rub the marinade all over the lamb leg, ensuring it is well coated. Cover and let it marinate in the fridge for at least 2 hours, preferably overnight.

  3. 3

    Preheat the Oven

    Preheat your oven to 180°C (350°F).

  4. 4

    Roast the Lamb

    Place the marinated lamb in a roasting pan and roast in the preheated oven for approximately 1.5 to 2 hours, or until the internal temperature reaches 60°C (140°F) for medium rare. Baste the lamb with its juices every 30 minutes.

  5. 5

    Rest and Serve

    Remove the lamb from the oven, cover it with foil, and let it rest for 15-20 minutes before carving.

Mashed Potatoes

  1. 6

    Prepare the Potatoes

    Peel and chop the Yukon Gold potatoes into evenly-sized pieces.

  2. 7

    Boil the Potatoes

    Place the chopped potatoes in a large pot, cover with cold water, and add a teaspoon of salt. Bring to a boil and cook until the potatoes are fork-tender, about 15-20 minutes.

  3. 8

    Drain and Mash

    Drain the potatoes and return them to the pot. Add butter, milk, salt, and black pepper. Mash the potatoes until smooth and creamy.

  4. 9

    Serve

    Serve the mashed potatoes alongside the carved lamb for a hearty dinner.
