Number Of Ingredients 9

1 cup dry red wine
3/4 cup chopped shallot
1/2 cup whole grain Dijon mustard
1/3 cup plus 1 tablespoon finely chopped fresh sage
1/4 cup olive oil
3 garlic cloves, pressed
7 lbs leg of lamb, boned, evenly flattened, outside fat partially trimmed (yields about 5 2/3 pounds)
1 cup low sodium beef broth
2 tablespoons chilled unsalted butter, cut into 1/2-inch cubes

Steps:

Whisk wine, shallots, mustard, 1/3 cup chopped sage, oil, and garlic in medium glass bowl.
Transfer 1/2 cup marinade to small bowl; reserve for sauce.
Cover and chill.
Place leg of lamb in 2-gallon resealable plastic bag.
Pour remaining marinade into bag; seal.
Turn bag to coat, arranging lamb in 1 flat piece.
Place lamb in marinade on rimmed baking sheet. Chill overnight, turning occasionally.
Combine reserved 1/2 cup marinade and beef broth in small saucepan.
Boil until reduced to 3/4 cup, about 12 minutes.
Cool, cover, and chill.
Prepare barbecue (medium heat).
Remove lamb from plastic bag and transfer to large rimmed baking sheet with some marinade still clinging.
Open lamb like book and sprinkle on both sides with salt and pepper.
Transfer lamb to grill.
Cover and grill until charred and instant-read thermometer inserted into meat registers 135°F for medium-rare, about 10 minutes per side (some thicker pieces can be cut away from leg and grilled longer if desired).
Transfer to work surface; let rest 10 minutes.
Rewarm sauce.
Whisk in butter and remaining 1 tablespoon chopped sage.
Season to taste with salt and pepper.
Thinly slice lamb against grain. Transfer to platter.
Spoon some of sauce over. Garnish with fresh sage sprigs, if desired.
