📝 Instructions

13 steps
1

Preheat your oven to 200°C (400°F).

2

Pat the lamb leg dry with paper towels and set it aside in a roasting pan.

3

Peel the garlic cloves and cut them into thin slivers.

4

Using a small sharp knife, make small incisions all over the lamb and insert the garlic slivers into the cuts.

5

Rub the lamb with olive oil, then season generously with kosher salt and black pepper.

6

Strip the leaves off 2 sprigs of rosemary and finely chop them. Sprinkle the chopped rosemary over the lamb.

7

Cut the lemon in half, squeezing the juice over the lamb and placing the lemon halves in the roasting pan.

8

Peel and chop the onion, carrots, and baby potatoes into evenly sized pieces. Spread them around the lamb in the roasting pan and drizzle with a little olive oil.

9

Place the remaining rosemary sprigs on top of the lamb and vegetables.

10

Roast the lamb in the preheated oven for about 1 hour and 30 minutes, or until the internal temperature reaches 60°C (140°F) for medium-rare or 70°C (160°F) for medium.

11

Baste the lamb with the juices from the pan every 30 minutes to keep it moist.

12

Once cooked, remove the lamb from the oven and cover loosely with aluminum foil. Let it rest for 15 minutes before carving.

13

Serve the roast lamb with the roasted vegetables and drizzle with the pan juices.
