🥗 Ingredients

The Lamb

  • 2.5 kg Saddle of Lamb (bone-in, rolled and tied by your butcher)
  • 2 teaspoons Kosher Salt (more for seasoning)
  • 1 teaspoon Black Pepper (freshly cracked)
  • 2 tablespoons Olive Oil (high smoke point)

Herb Crust

  • 1 cup Fresh Flat-Leaf Parsley (finely chopped)
  • 2 tablespoons Fresh Rosemary (leaves only, minced)
  • 1 tablespoon Fresh Thyme (leaves only)
  • 4 cloves Garlic (minced into a paste)
  • 1/2 cup Panko Breadcrumbs (toasted lightly)
  • 3 tablespoons Dijon Mustard (used as a binder)

For the Jus

  • 1 cup Dry Red Wine (such as Cabernet or Syrah)
  • 2 cups Lamb or Beef Stock (high quality, low sodium)
  • 2 pieces Shallots (finely diced)
  • 2 tablespoons Cold Unsalted Butter (cubed)

👨‍🍳 Instructions

  1. 1

    Remove the lamb from the refrigerator at least 1 hour before cooking to bring it to room temperature; this ensures even roasting.

  2. 2

    Preheat your oven to 200°C (400°F). Pat the lamb completely dry with paper towels to ensure a good sear.

  3. 3

    Using a sharp knife, score the fat on the top of the saddle in a diamond pattern, being careful not to cut into the meat.

  4. 4

    Season the entire lamb generously with salt and pepper. Heat olive oil in a large, oven-proof roasting pan over medium-high heat on the stovetop.

  5. 5

    Sear the lamb on all sides until deeply golden brown, about 3-4 minutes per side. Remove the lamb temporarily to a tray.

  6. 6

    In a small bowl, mix the parsley, rosemary, thyme, minced garlic, and panko breadcrumbs until well combined.

  7. 7

    Brush the top (fat side) of the seared lamb generously with Dijon mustard, then press the herb and breadcrumb mixture firmly onto the mustard to create a thick crust.

  8. 8

    Place the lamb back into the roasting pan and transfer to the oven. Roast for 45-55 minutes, or until a meat thermometer registers 52°C (125°F) for medium-rare.

  9. 9

    Transfer the lamb to a carving board and tent loosely with foil. Let it rest for at least 20 minutes; this is crucial for the juices to redistribute.

  10. 10

    While the lamb rests, pour off excess fat from the roasting pan, leaving about 1 tablespoon. Add shallots and sauté over medium heat until softened.

  11. 11

    Deglaze the pan with red wine, scraping up all the browned bits (fond) from the bottom. Reduce the wine by half.

  12. 12

    Add the stock and simmer until the liquid has reduced to a syrupy consistency. Strain through a fine-mesh sieve into a clean saucepan.

  13. 13

    Whisk in the cold butter one cube at a time to create a glossy, thickened jus. Season with salt to taste.

  14. 14

    Carve the saddle by slicing vertically against the bone to release the loins, then slice into thick medallions.

💡 Chef's Tips

Always use a meat thermometer; lamb can go from perfect to overdone in just a few minutes. If the herb crust begins to brown too quickly in the oven, cover it loosely with a small piece of foil. Ask your butcher to provide the 'lamb trimmings' to toss into the roasting pan for extra flavor in the jus. Resting is non-negotiable; cutting too early will result in dry meat and a messy carving board.

🍽️ Serving Suggestions

Serve with buttery fondant potatoes and honey-glazed heirloom carrots. Pair with a bold Bordeaux or a peppery Northern Rhône Syrah. A side of minted pea purée provides a fresh, vibrant contrast to the rich meat. Offer a small bowl of traditional mint sauce or redcurrant jelly on the side for guests.
