Italian Leg of Lamb

Ingredients :

1/2 cup lemon juice
1/2 cup olive oil
2 tablespoons dried oregano
2 teaspoons ground mustard
1 teaspoon garlic powder
4 garlic cloves, minced
1 (5 pound) boneless leg of lamb

DIRECTIONS

1. In a small bowl, combine the lemon juice, oil and seasonings. Pour half of the marinade into a large resealable plastic bag; add lamb. Seal bag and turn to coat; refrigerate for at least 2 hours or overnight. Cover and refrigerate remaining marinade.
2. Drain and discard marinade from lamb. Place lamb fat side up on a rack in a shallow roasting pan. Bake, uncovered, at 325 degrees F for 2-1/4 to 3 hours or until meat reaches desired doneness (for medium, a meat thermometer should read 160 degrees F; well-done, 170 degrees F), basting occasionally with reserved marinade. Let stand for 10-15 minutes before slicing.
