1 six- to seven-pound leg of lamb, trimmed
Coarse salt and freshly ground pepper
2 garlic cloves, thinly sliced
2 tablespoons plus 2 teaspoons Dijon mustard
2 tablespoons chopped fresh thyme, plus 1 bunch for pan and garnish
1 tablespoon chopped fresh rosemary, plus 1 bunch for pan and garnish
2 tablespoons extra-virgin olive oil
2 onions, peeled and quartered
4 carrots, peeled
4 stalks celery
6 new potatoes, halved if large
2 tablespoons all-purpose flour
2 tablespoons unsalted butter, softened
1/2 cup dry red wine
1 cup homemade or canned beef stock

Steps:

Preheat oven to 500 degrees. Season lamb with salt and pepper. Make 1-inch slits all over; place a sliver of garlic in each. Rub 2 tablespoons mustard over lamb; coat evenly with thyme and rosemary, patting gently.
Rub oil over bottom of roasting pan; cover with herb bunches. Place lamb on top. Roast 20 minutes; reduce heat to 375 degrees. Add onions, carrots, celery, and potatoes; season with salt and pepper. Roast until meat thermometer inserted near center, avoiding bone, reads 140 degrees, about 70 minutes. Transfer lamb and vegetables to a platter; let rest 20 minutes.
Meanwhile, make sauce: Knead flour and butter together. Pour off fat; place pan over medium heat. Add wine; reduce by half. Add remaining mustard and stock. Stir; reduce slightly. Strain into a saucepan; simmer. Add butter mixture in small pieces, whisking constantly. Remove from heat; season with salt and pepper. Garnish with herbs.
