Ingredients
- 2.4 kg Leg of Lamb (bone‑in, trimmed)
- 2 tbsp Olive Oil (extra‑virgin)
- 1 tbsp Salt (kosher or sea salt)
- 1 tsp Black Pepper (freshly ground)
- 4 Garlic Cloves (peeled, whole)
- 4 sprigs Fresh Rosemary (stems removed, leaves stripped)
- 4 Anchovy Fillets (packed in oil, drained)

Instructions
Preheat Oven
Set the oven to 220°C and allow it to fully preheat.
Time: PT10M
Temperature: 220°C
Season the Lamb
Pat the leg of lamb dry, rub with olive oil, then season generously with salt and black pepper all over.
Time: PT5M
Create Flavor Slits
Using a small paring knife, make evenly spaced slits about 2.5 inches apart down to the bone, inserting a finger to keep each slit open.
Time: PT5M
Insert Garlic‑Rosemary‑Anchovy Mix
Place a peeled garlic clove, a rosemary leaf and an anchovy fillet into each slit, pushing gently so the mixture stays inside.
Time: PT5M
Prepare the Trivet
Roughly chop carrots, celery and onion into large chunks. Scatter them in the bottom of the roasting pan, add the glass of water, and set aside.
Time: PT10M
Position the Lamb
Place the seasoned lamb directly on the oven rack (or the top bars) above the roasting pan so the fat can drip down onto the vegetables.
Time: PT5M
Roast the Lamb
Insert the meat thermometer into the thickest part of the leg. Roast at 220°C for 15 minutes, then lower the oven to 180°C and continue roasting until the internal temperature reaches 63°C for medium‑rare (about 2 hours total) or 83°C for well‑done. Remove from oven when desired doneness is reached.
Time: PT2H40M
Temperature: 180°C
Rest the Lamb
Transfer the lamb to a cutting board, tent loosely with foil and let rest for at least 30 minutes before carving.
Time: PT30M
