Main Ingredients

Aging Ingredients

Method

Preparation

  1. 1

    Prepare the Lamb

    Start by trimming any excess fat from the lamb leg. You want to keep some fat for flavor, but too much can lead to greasiness.

  2. 2

    Season the Lamb

    In a small bowl, mix the kosher salt, black pepper, minced garlic, and chopped rosemary. Rub this mixture all over the lamb leg, ensuring it is evenly coated.

  3. 3

    Add Olive Oil

    Drizzle the olive oil over the seasoned lamb, rubbing it in gently to help the seasoning adhere.

Aging Process

  1. 4

    Prepare the Aging Bag

    Place the seasoned lamb leg into the large vacuum sealable aging bag. Make sure the bag is clean and dry.

  2. 5

    Add Aging Ingredients

    Pour the red wine and chopped fresh thyme into the bag with the lamb. This will help enhance the flavor during the aging process.

  3. 6

    Seal the Bag

    Vacuum seal the bag tightly to remove as much air as possible. If you don’t have a vacuum sealer, you can use a zipper-lock bag and remove the air manually.

  4. 7

    Refrigerate

    Place the sealed bag in the refrigerator. Let the lamb age for 28 days, turning the bag every few days to ensure even exposure to the marinade.

Cooking

  1. 8

    Preheat the Oven

    After 28 days, preheat your oven to 375°F (190°C).

  2. 9

    Remove from Aging Bag

    Take the lamb leg out of the aging bag and discard any liquid. Pat the lamb dry with paper towels.

  3. 10

    Roast the Lamb

    Place the lamb leg on a roasting rack in a baking pan. Roast in the preheated oven for about 1.5 to 2 hours, or until the internal temperature reaches 135°F (57°C) for medium-rare. Use a meat thermometer for best results.

  4. 11

    Rest the Lamb

    Once cooked, remove the lamb from the oven and let it rest for at least 15-20 minutes before slicing. This allows the juices to redistribute.

  5. 12

    Serve

    Slice the lamb leg against the grain and serve with your favorite sides.
