Lamb Shoulder with White Bean Ragout

Place lamb as flat as possible on work surface; cut almost but not all the way through thick parts to open like book and make even thickness. Trim off any sinew or fat; set aside.

In food processor, finely chop together parsley, thyme, rosemary, garlic, salt and pepper. Add all but 1 tbsp (15 mL) of the oil; blend until smooth, 1 to 2 minutes. Spread over cut surface of meat; roll up and tie with kitchen string.

In Dutch oven, heat remaining oil over medium-high heat; brown lamb all over, about 10 minutes. Cover and roast in 300°F (150°C) oven for 2 hours. Transfer to cutting board and tent with foil; let stand for 15 minutes before carving into 1/2-inch (1 cm) thick slices.

Meanwhile, spoon off fat from pan juices. Add stock and bring to boil over high heat; boil until reduced by half, about 10 minutes. Mix cornstarch with 1 tbsp (15 mL) water; stir into sauce and cook for 30 seconds. Stir in basil.

White Bean Ragout:
Meanwhile, in saucepan, heat oil over medium heat; cook carrot, celery and onion, stirring occasionally, for 5 minutes. Stir in beans, stock and salt ; cook until reduced and beans are coated, about 15 minutes. Add tomatoes and heat through; stir in parsley and thyme.

Divide bean mixture among warmed plates; top each with lamb slices. Pour sauce over top.
