How to make Herb-Roasted Leg of Lamb with Vegetables and Jus

Preheat oven to 204°C.

In roasting pan, combine onions, celery, and garlic cloves. Drizzle with 1 tablespoon oil, toss well to coat, and mound in centre of pan. Set lamb atop mixture. Drizzle with 1 tablespoon oil and sprinkle with herbes de Provence, salt, and pepper. Arrange carrots and celery root around meat and drizzle with remaining 2 tablespoons oil. Pour wine and broth into pan and cover pan tightly with heavy-duty foil.

Roast 1 hour. Remove foil and increase heat to 218°C. Roast until thermometer inserted into thickest part of lamb registers 54°C for medium-rare, about 15 minutes more.

Transfer lamb to carving board and tent with foil. Transfer carrots, celery root, and 1/2 of onions to medium bowl and keep warm. Force remaining contents of pan through medium-mesh strainer into medium saucepan, pressing well on solids. Skim off and discard fat. (Or pour pan juices through strainer into fat separator and let stand until fat rises to top, 1 to 2 minutes. Carefully pour pan juices from separator into pan, discarding fat.)

Set saucepan over moderate heat and bring to simmer. Cook, uncovered, until reduced by half, about 10 minutes. Season to taste with salt and pepper.

Remove kitchen string from lamb and cut meat crosswise into thin slices. Arrange on platter with roasted vegetables. Serve warm, with jus alongside.
