Ingredients

• 2-3 kg (approx. 4.5-6.5 lbs) boneless leg of lamb (or bone-in, with adjusted cooking time)
• 4 large cloves garlic, thinly sliced
• 2 hearty sprigs fresh rosemary, finely chopped (about 2 tablespoons)
• 1 tablespoon olive oil
• 1 teaspoon salt (or to taste)
• ½ teaspoon freshly ground black pepper (or to taste)
• Optional for extra depth: 4 anchovy fillets, mashed into a paste (don't worry, you won't taste fish, just umami!)

Directions

1. Preheat & Prepare: Start by preheating your oven to a hot 220°C (425°F). While the oven heats, unwrap your boneless leg of lamb. Pat it thoroughly dry with paper towels – this is a crucial step for achieving a beautiful, crispy crust! Using a sharp knife, make small, shallow incisions (about 1/2 inch deep) all over the surface of the lamb, focusing on the fattier areas. These pockets are where all the flavor will go!
2. Flavor Infusion: In a small bowl, combine the olive oil, chopped rosemary, salt, and pepper. If using, mix in the mashed anchovy fillets. Take your sliced garlic cloves and tuck them deep into the incisions you made in the lamb. Then, generously rub the entire lamb roast with the herb and oil mixture, ensuring it gets into all the crevices. Don't be shy; really massage that flavor in!
3. The Roast Begins: Place the seasoned lamb directly onto a rack in a roasting pan. Pop it into your preheated 220°C (425°F) oven for an initial blast of high heat for 20 minutes. This high temperature helps to sear the exterior, locking in those precious juices and starting to develop a lovely crust.
4. Slow & Steady: After 20 minutes, reduce the oven temperature to 180°C (350°F). Continue to roast the lamb for approximately 1 hour. For a boneless lamb leg roast, a good rule of thumb is about 20-25 minutes per pound for medium-rare to medium. If you're using a bone-in leg, add an extra 10-15 minutes per pound.
5. Check for Doneness: The best way to ensure your lamb is cooked to perfection is with a meat thermometer. Insert it into the thickest part of the lamb, avoiding any bone.
   1. For rare: 55-60°C (130-140°F)
   2. For medium: 60-65°C (140-150°F)
   3. For well-done: 70°C (160°F)
   Remove the lamb from the oven about 5 degrees below your target temperature, as it will continue to cook while it rests.
6. The All-Important Rest: This step is non-negotiable for a juicy roast! Once removed from the oven, loosely tent the lamb with aluminum foil and let it rest on a cutting board for at least 15 minutes, or even up to 20-30 minutes for a larger roast. This allows the juices to redistribute throughout the meat, resulting in an incredibly tender and moist final product.
7. Slice & Serve: After resting, slice the lamb against the grain into thick, beautiful slices. Arrange on a platter and serve immediately with your chosen sides. Enjoy your delicious roast lamb recipe oven masterpiece!
