Roast Leg of Lamb with Rosemary and Garlic

The English Sunday and Easter roast: a leg of lamb deeply studded with slivers of garlic and rosemary, roasted until the outside is burnished and the inside blushing pink, rested and carved, and served with rosemary gravy and mint sauce

Origin: England, United Kingdom

From the journey of Rosemary.

Roast leg of lamb is the centrepiece of the English Easter and Sunday table, and rosemary is its inseparable partner, the herb that has flavoured English lamb since the plant took root in the medieval garden. The classic method is the simplest: deep incisions cut all over the leg and each one plugged with a sliver of garlic and a tuft of rosemary, so the herb scents the meat to its heart as it roasts. Lamb and rosemary is one of the great fixed marriages of the English kitchen, set down beside mint sauce, redcurrant jelly, and roast potatoes as immovable Sunday law. The same herb that the English wear and scatter for remembrance is the one they push into the Sunday joint.

Ingredients

Lamb

  • 2.2 kg leg of lamb, bone in
  • 6 cloves garlic, cut into slivers
  • 6 sprigs fresh rosemary, broken into small tufts, plus 2 tbsp leaves
  • 2 tbsp olive oil
  • 1 tsp flaky sea salt
  • 0.5 tsp black pepper

Gravy

  • 200 ml red wine or lamb stock
  • 1 tbsp plain flour (optional, to thicken the gravy)

Method

  1. Preheat the oven to 220°C (200°C fan / 425°F). Pat the lamb dry. With a small sharp knife, make deep incisions all over the leg and push a sliver of garlic and a tuft of rosemary into each.
  2. Mix the 2 tbsp rosemary leaves with the olive oil, salt, and pepper, and rub all over the lamb.
  3. Roast at the high heat for 20 minutes to brown, then lower the oven to 180°C (160°C fan / 350°F) and roast for about 50 to 55 minutes for pink lamb (around 55°C to 60°C internal temperature at the thickest point), or longer for more well done.
  4. Lift the lamb onto a board, cover loosely with foil, and rest for 20 minutes. This rest is essential for juicy, carvable meat.
  5. Make the gravy: pour off excess fat from the tin, set it over a low heat, sprinkle in the flour if using and cook for a minute, then pour in the wine or stock and simmer, scraping up the caramelised bits, into a glossy rosemary gravy.
  6. Carve the lamb and serve with the gravy, mint sauce, roast potatoes, and seasonal greens.

Notes

A bone-in leg gives the best flavour, but a boned and rolled leg is easier to carve and takes slightly less time. The same rosemary-and-garlic treatment is superb on a shoulder, slow-roasted for several hours at a lower temperature until it pulls apart. For a Greek or Provençal accent, add lemon and oregano or anchovy to the studding; for the classic English roast, keep it to rosemary and garlic.

Rosemary

Rosemary

Salvia rosmarinus (syn. Rosmarinus officinalis)

HerbsLamiaceae (the mint family): an evergreen aromatic shrub

🌍Origin

Mediterranean Basin — Gathered wild since deep antiquity from the rocky coasts of the Mediterranean basin; a single species (Salvia rosmarinus, long classified as Rosmarinus officinalis)

🌱Domestication

Rosemary is, unlike many of the great culinary herbs, a single species rather than a cluster of related plants: one evergreen, needle-leaved shrub of the Mediterranean coast, known to botanists for centuries as Rosmarinus officinalis and, since a molecular reclassification in 2017, as Salvia rosmarinus, a member of the vast sage genus. There are many cultivars, the tall upright bushes prized for cooking and the low, trailing, prostrate forms that spill over Mediterranean walls, but they are all one plant, and there is no second wild species in some distant land waiting to be claimed as another rosemary. The herb that scents a Tuscan roast, a Provençal grill, a Californian focaccia, and an Australian leg of lamb is, everywhere, the same Mediterranean shrub. Rosemary is a creature of the dry, rocky, sun-struck Mediterranean littoral, the limestone garrigue and coastal maquis where it grows wild within sight and scent of the sea. It is from this habitat that it takes its ancient Latin name, ros marinus, the dew of the sea, for the plant thrives on the salt-laden mists of the shore and seems to drink the very spray. Its tough, resinous, blue-flowered evergreen leaves are armoured against drought and heat, and they are dense with the aromatic compounds that give rosemary its unmistakable character: not the thymol of thyme but a piney, camphoraceous, faintly eucalyptus-like bouquet built on cineole, camphor, and the powerful antioxidants rosmarinic and carnosic acid. It was never domesticated in the manner of a grain; it was gathered from the wild hillsides for thousands of years and, in the gardens of antiquity and the cloisters of the Middle Ages, brought under cultivation as a plant of the kitchen, the apothecary, the altar, and the grave. More than almost any other herb, rosemary has carried a freight of meaning beyond its flavour. Its evergreen constancy and its lingering, memory-stirring scent made it, from the earliest Greek records, the herb of remembrance and fidelity, woven into the rites of weddings and of funerals alike, a plant that promised that the dead and the absent would not be forgotten. That double life, as one of the most useful seasonings of the Mediterranean kitchen and as the West's enduring emblem of memory, has followed rosemary across every sea it has crossed.

Global Voyage

Rosemary's journey is the spread of a single Mediterranean shrub outward from its native shore, first by the cultures of classical antiquity and then, in the age of empire, to the Mediterranean-climate corners of the New World. To the ancient Greeks rosemary was already the herb of memory: students are said to have wound it through their hair while studying, and it was burned as incense and held sacred to Aphrodite. Rome inherited and deepened the symbolism, holding rosemary sacred, weaving it into household rites, weddings, and funerals, planting it in every garden, and recording its virtues in the works of Pliny the Elder and Dioscorides. With their legions and their kitchen gardens the Romans carried the plant the length of the empire, north into Gaul and Britain, beginning its long naturalisation in the cooler lands beyond its native warmth. Through the Middle Ages rosemary moved on the twin currents of the kitchen and the still-room. Charlemagne ordered it grown on the imperial estates in his Capitulare de Villis of around 795, the monastic infirmary gardens cultivated it as a medicine, and in the fourteenth century it became the base of Hungary Water, by tradition compounded for an ailing queen of Hungary and counted amongst the first alcoholic perfumes of Europe. By tradition rosemary was carried to England in 1338, in a bundle sent to Queen Philippa of Hainault, and it took such root in the English imagination that Shakespeare could have Ophelia say, and every audience understand, 'There's rosemary, that's for remembrance.' It was scattered at weddings and laid upon coffins, and it became the classic English partner to roasted lamb. It was in the cooking of the Mediterranean heartland, though, that rosemary found its fullest culinary expression. In Italy, and above all in Tuscany, rosmarino is a foundation of the kitchen: the perfume of arista, the rosemary-and-garlic roast pork, of lamb and of fagioli all'uccelletto, of rosemary roast potatoes, of the rosemary focaccia of Liguria, and of castagnaccio, the chestnut cake strewn with rosemary and pine nuts. In Provence romarin is a pillar of herbes de Provence and the bouquet garni and the breath of the garrigue. In Spain romero scents the slow roasts of Castile and yields the celebrated rosemary honey of the scrub, and in Greece dendrolivano flavours roasts and the baked chickpeas of the Cyclades. The Mediterranean empires then carried rosemary to lands with climates much like its own. Spanish Franciscan missionaries planted it, with the vine and the olive, in the gardens of their Alta California missions from 1769, and in California's Mediterranean climate it flourished so completely that it became at once a ubiquitous landscaping plant and, in the late twentieth century, a signature of the new California cuisine. The Spanish crown carried it likewise to the River Plate, where romero entered the criollo kitchen of Argentina. British settlers took it to Australia, where it thrives in the Mediterranean south and flavours the national love of roasted and barbecued lamb. And in Australia and New Zealand rosemary acquired a final, poignant meaning: because the herb grows wild on the Gallipoli peninsula, where so many fell in 1915, sprigs of rosemary are worn each year on Anzac Day and Remembrance Day, the ancient emblem of memory bound at last to the memory of a war.

🍽Modern Culinary Role

Rosemary is one of the most widely used culinary herbs in the world, and the most robust of the classic European aromatics. Its tough, resinous needles withstand long, high heat that would destroy a tender herb, which has made it the definitive partner of roasted and grilled meats, above all lamb and pork, and of the slow braise, the roast potato, the bean stew, and the oven bread. It anchors the cooking of the whole northern Mediterranean, from Tuscan arista and Ligurian focaccia to Provençal grills and Castilian roasts, and it is a defining component of both herbes de Provence and the bouquet garni. Beyond its Mediterranean home it has become a fixture of the modern kitchen across the Mediterranean-climate world, indispensable in California, Australia, South Africa, Chile, and Argentina, and a standard of the supermarket herb shelf everywhere. The herb keeps its ancient double identity as food and medicine, now on a far larger scale. Rosemary extract, rich in the antioxidants carnosic and rosmarinic acid, is one of the most important natural food preservatives in the world, used industrially to keep fats and oils from turning rancid and approved as a food additive. Rosemary essential oil is a mainstay of aromatherapy and cosmetics, and modern studies of its effect on alertness and recall have lent a curious scientific echo to the herb's three-thousand-year reputation for strengthening the memory. Rosemary honey from the Spanish and Mediterranean scrub remains amongst the most prized of monofloral honeys. And rosemary has never shed its symbolism. It is still the herb of remembrance: planted in gardens of memory, laid at funerals, and, across Australia and New Zealand, worn over the heart each Anzac Day, a living sprig of the Mediterranean shrub that grows wild on the shores of Gallipoli. Few plants carry their meaning so far from home, or hold it so long.
