Classic Roast Leg of Lamb
The roast leg of lamb — the centrepiece preparation of the European Easter table — requires the same larding-with-aromatics technique as Hazan's veal and the same doneness precision. The target: pink throughout the leg, with the bone-end slightly more cooked and the thick end at 58–60°C internal temperature.

The Method
1
Remove the leg of lamb from the refrigerator at least 45 minutes before roasting. Using a small sharp knife, cut incisions at regular intervals across the entire surface of the leg — both faces and around the shank. Insert a sliver of garlic and a small piece of rosemary into each incision, pressing them flush with the meat. Rub the leg all over with olive oil, then season with salt and freshly ground black pepper. The larding is complete when every incision is filled and no garlic or rosemary protrudes above the surface.

Heat the oven to 200°C. Set the leg fat-side up on a rack in a roasting pan. Roast at 200°C for 20 minutes. The surface is ready to proceed when it has taken on a deep golden-brown crust and the fat has begun to render visibly into the pan.
3
Reduce the oven to 180°C. Continue roasting until a probe thermometer inserted into the thickest part of the leg — away from the bone — reads 58–60°C for medium-rare, the European standard. This is where the dish lives or dies: above 68°C the texture and flavour of the lamb deteriorate irreversibly; the bone-end will register slightly higher than the thick end, which is expected and correct.
4
If finishing with the persillade: when the internal temperature is approximately 10°C below the target, remove the leg from the oven. Brush the upper surface evenly with Dijon mustard. Combine the breadcrumbs, chopped parsley, chopped garlic, and olive oil into a cohesive mixture and press it firmly onto the mustard in an even layer. Return the leg to the oven for a final 15 minutes. The crust is done when it is uniformly golden and crisp to the eye.

Transfer the leg to a board and rest it, uncovered, for at least 15 minutes. Meanwhile, pour off excess fat from the roasting pan, set it over a medium flame, and deglaze with the white wine or broth, scraping up all the caramelised aromatics. Strain the jus through a fine sieve into a warm jug. The jus is ready when it has reduced slightly and the fat has been skimmed from the surface.

Quality Hierarchy
01
Reserve — A bone-in leg from a milk-fed or salt-meadow (pré-salé) lamb, dry-aged briefly by the butcher; aromatics from the kitchen garden on the day.
02
Estate — A named-farm, grass-fed bone-in leg from a specialist butcher; fresh rosemary and firm, dry-skinned new-season garlic.
03
Market — A quality supermarket bone-in leg, well-trimmed; fresh rosemary from a herb counter; standard garlic, firm and ungerminated.
04
House — Any bone-in leg of lamb; dried rosemary used for larding in the absence of fresh; garlic from a bulb with no visible sprouting.

Sensory Tests
◇Sight. A deep golden-brown crust forms across the fat cap and upper surface within the first 20 minutes at 200°C.
◇Touch. A probe thermometer inserted into the thickest part, clear of the bone, reads 58–60°C for medium-rare; the thick end gives only slightly under firm finger pressure.
◇Sight. The persillade crust is uniformly golden and visibly set — no pale or soft patches — after its final 15 minutes in the oven.
◇Sight. The natural jus, once strained, runs clear amber with no emulsified fat remaining on the surface.
◇Smell. During resting, the roasted garlic and rosemary fragrance deepens and the sharp smell of raw lamb fat is entirely absent.
◇Where it lives or dies. The dish lives or dies at the thermometer: pull the leg at 58–60°C internal temperature — above 68°C the lamb's flavour and texture have deteriorated beyond recovery.

What to Pour
A structured red wine with sufficient acidity to cut the rendered fat and complement the herb crust — a red Bordeaux, a Côtes-du-Rhône, or a Rioja Reserva suits the dish's Franco-European register; if the persillade crust is used, a wine with some earthy, herbal character is preferred over a purely fruit-forward style.
