Rocket-Stuffed Leg of Lamb with Roasted Spring Vegetables

This elegant rocket-stuffed leg of lamb is a spectacular centrepiece for any special occasion or Sunday lunch. The butterflied lamb is filled with a vibrant mixture of sautéed rocket and zesty lemon, then rolled and roasted until perfectly tender. Using a herb paste of fresh oregano and garlic ensures a deeply savoury crust that complements the succulent meat, while the rich red wine gravy adds a sophisticated finish to every slice.

As a high-protein main course, this dish is naturally satisfying and pairs beautifully with the accompanying roasted spring vegetables. By roasting the potatoes, carrots and asparagus in the same pan, the vegetables absorb the delicious lamb juices, creating a cohesive and effortless meal. It is an excellent choice for a healthy yet indulgent family gathering, offering a modern twist on the classic British roast lamb.

  • Salt

  • Freshly ground black pepper

  • Kitchen string

  • a heavy roasting pan

In a 12-inch heavy skillet over medium-high heat, cook garlic in olive oil, stirring, until it begins to turn pale golden, then add rocket in batches, stirring and turning over with tongs until slightly wilted before adding each new batch, and continue sautéing until completely wilted, about 1 minute more. Season with salt, and transfer rocket filling to a large sieve set over a bowl to drain. Let cool.

With a food processor running, add garlic cloves, one at a time, through feed tube, and finely chop. Add oregano, lemon zest, olive oil, 1 teaspoon salt, and 1/2 teaspoons pepper to processor, and pulse until paste is well blended.

Pat the lamb dry. Arrange it, boned side up, on a work surface. Patch any holes with slices of meat from the edge, and season it with 3/4 teaspoons salt and 1/4 teaspoons pepper. Rub boned side with half of oregano paste, then top it evenly with all of the rocket mixture, leaving a 1-inch border around the edges.

Beginning with a short side, roll up lamb, enclosing rocket (the rolled roast will appear messy and ungainly, but once it's roasted, it will look delicious). Snugly tie roast closed, crosswise at 1-inch intervals and around the length, with kitchen string.

Transfer lamb to a roasting pan and rub it all over with the remaining oregano paste. Let it stand for 1 hour at room temperature.

Put oven rack in middle of oven and heat oven to 232°C.

Roast lamb for 30 minutes.

Cut each onion lengthwise into eighths, and halve potatoes or quarter if large. Toss onions, potatoes, and carrots with 2 tablespoons oil, 1/2 teaspoons salt, and 1/4 teaspoons pepper. Scatter vegetables (not including asparagus) around lamb in the pan, then reduce oven temperature to 177°C, and roast lamb until an instant-read thermometer inserted into centre of thickest part of roast registers 54°C for medium-rare meat (test temperature in several places), 40 to 50 minutes more. Transfer lamb to a platter and tent loosely with foil, then let it stand for 30 minutes.

While lamb is standing, increase oven to 232°C, then stir vegetables in pan, and continue to roast until tender, 10 to 15 minutes.

Toss asparagus with remaining 1/2 tablespoons oil and 1/8 teaspoons salt, and scatter among roasted vegetables, then continue to roast until asparagus is just tender, about 10 minutes.

Transfer vegetables with a slotted spoon to a serving dish, and keep warm, loosely covered. Reserve roasting pan.

Skim any fat from the pan drippings in roasting pan, and set roasting pan over 2 burners over medium-high heat. Add wine and deglaze the pan by boiling the liquid, scraping up the brown bits, for 1 minute. Strain the liquid through a fine-mesh sieve into a saucepan, then boil until reduced by half (to about 80ml ). Add chicken stock and any juices that have accumulated on the platter, and boil the sauce until reduced to about 250g . Reduce heat to a simmer.

Stir the cornflour mixture, then add it to simmering sauce; continue to simmer sauce, stirring, for 1 minute. Season sauce with salt and pepper and keep it warm.

Discard the strings from the lamb, then carve lamb into thin slices on a cutting board and serve it with sauce and vegetables.
