Ingredients
2 kg bone-in leg of lamb
1 kg potatoes, peeled and cut into chunks
4 cloves garlic, sliced
4 sprigs fresh rosemary
3 tablespoons olive oil
2 teaspoons salt
1 teaspoon black pepper
1 cup chicken or beef stock
2 tablespoons all-purpose flour
Instructions
Preheat oven to 200°C (400°F).
Make small incisions all over the lamb and insert garlic slices and rosemary leaves.
Rub lamb with 2 tablespoons olive oil, salt, and pepper. Place in a roasting pan.
Roast lamb for 30 minutes. Meanwhile, parboil potatoes in salted water for 10 minutes, then drain and shake to roughen edges.
Toss potatoes with remaining 1 tablespoon olive oil and a pinch of salt. Add to roasting pan around the lamb.
Reduce oven to 180°C (350°F) and continue roasting for 1 hour 30 minutes, or until lamb reaches 60°C (140°F) for medium-rare, basting occasionally.
Remove lamb and potatoes from pan; keep warm. Place roasting pan on stovetop over medium heat. Add stock and bring to a boil, scraping up browned bits.
Whisk flour with a little water to make a paste, then stir into pan juices. Simmer until thickened to make gravy. Season to taste.
Carve lamb and serve with potatoes and gravy.
Tips
Let lamb rest for 15 minutes before carving for juicier meat.
Add vegetables like carrots or parsnips to the roasting pan for a complete meal.
For crispier potatoes, parboil with a teaspoon of baking soda.
