New Zealand Lamb Rack with Rosemary, Garlic, and Kumara Mash - New Zealand traditional dish

🧂 Ingredients

  • 1 kg Rack of lamb(frenched)
  • 2 sprigs Fresh rosemary(chopped)
  • 4 cloves Garlic(minced)
  • 2 tbsp Olive oil
  • 1 tsp Salt
  • 0.5 tsp Black pepper
  • 1 kg Kumara (sweet potato)(peeled and cubed)
  • 50 g Butter
  • 100 ml Milk(warm)

👨‍🍳 Instructions

  1. 1

    Preheat oven to 200°C (180°C fan/400°F/Gas Mark 6).

    💡 Tip: Allow the oven to fully preheat before placing the lamb.
  2. 2

    In a small bowl, mix chopped rosemary, minced garlic, olive oil, salt, and pepper. Rub this mixture all over the rack of lamb.

    💡 Tip: Ensure an even coating for maximum flavor.
  3. 3

    Sear the lamb rack in a hot, oven-safe pan for 2-3 minutes per side until browned.

    💡 Tip: This step creates a flavorful crust.
  4. 4

    Transfer the pan to the preheated oven and roast for 15-20 minutes for medium-rare, or until desired doneness.

    💡 Tip: Use a meat thermometer: 55°C (130°F) for medium-rare, 60°C (140°F) for medium.
  5. 5

    While the lamb is roasting, boil the cubed kumara in salted water until tender, about 15-20 minutes.

    💡 Tip: Drain the kumara thoroughly.
  6. 6

    Mash the cooked kumara with butter and warm milk until smooth and creamy. Season with salt and pepper to taste.

    💡 Tip: Add more milk if a thinner mash is desired.
  7. 7

    Once the lamb is cooked, remove it from the oven and let it rest for 10 minutes before carving.

    💡 Tip: Resting allows the juices to redistribute, resulting in a more tender lamb.
  8. 8

    Serve slices of the rested lamb rack with a generous portion of kumara mash.

💡 Pro Tips

  • Frenched lamb racks look more impressive and are easier to carve.
  • Don't overcook the lamb; it should be pink and juicy.
  • Kumara mash can be made ahead and reheated gently.

🔄 Variations

  • Add a splash of red wine to the pan after searing the lamb and reduce to make a simple pan sauce.
  • Incorporate a pinch of nutmeg into the kumara mash for added warmth.
  • Serve with steamed green beans or asparagus for a complete meal.
