Preparation instructions
Prepare the Lamb Rack
1Preheat your oven to 120°C (250°F). Remove the lamb rack from the fridge 30 minutes before cooking to bring it to room temperature. This ensures even cooking.
Season the Lamb
2In a small bowl, mix minced garlic, chopped rosemary, lemon zest, salt, and pepper with olive oil to create a marinade. Rub this mixture thoroughly over the lamb rack, ensuring all sides are coated. Cover and let it marinate for about 15-20 minutes.
Slow Cook the Lamb
3Place the lamb rack on a roasting pan or oven-safe dish. Insert a meat thermometer into the thickest part of the lamb away from the bone. Put it in the preheated oven and slow cook until the internal temperature reaches 58-60°C (135-140°F) for medium-rare or 65°C (150°F) for medium. This should take around 2 to 2.5 hours. Slow cooking at low temp will make the lamb very tender and juicy.
Rest the Lamb
4Once the lamb reaches the desired internal temperature, remove it from the oven and cover loosely with foil. Let it rest for 15 minutes. This allows the juices to redistribute, making the meat tender and moist.
Serve
5Slice the lamb rack between the ribs to portions and serve immediately. Enjoy the tender and flavorful slow-cooked lamb!

FAQ
What is the safe internal temperature for lamb?
For medium-rare lamb, cook to an internal temperature of 58-60°C (135-140°F). For medium, cook to 65°C (150°F). Use a meat thermometer to check temperature to ensure safety and desired doneness.
Can I slow cook lamb rack without a thermometer?
While it's possible to cook without a thermometer, using one ensures the lamb is safe to eat and cooked to your preferred doneness. Otherwise, it’s harder to judge and may result in overcooked or undercooked meat.
Should I sear the lamb before slow cooking?
Searing is optional but recommended if you want a browned crust for extra flavor and texture. Make sure the lamb is patted dry before searing to get a good crust.
How do I avoid cross-contamination?
Use separate utensils and cutting boards for raw lamb and other ingredients. Wash hands and surfaces thoroughly after handling raw meat.
Can I use a slow cooker instead of the oven?
Yes, you can slow cook the lamb rack in a slow cooker on low for about 4-5 hours until tender, but the texture and crust might differ.
