1/2 cup fat-free, less-sodium chicken broth
1/2 cup balsamic vinegar
1/4 cup finely chopped shallots
1/4 cup packed brown sugar
1/4 teaspoon grated orange rind
1/4 cup fresh orange juice
1 (2-inch) piece vanilla bean, split lengthwise
3/4 teaspoon salt, divided
16 skinless, boneless chicken thighs (about 2 pounds)
1/2 teaspoon freshly ground black pepper
Orange rind strips (optional)
Preheat oven to 450?.
Combine first 6 ingredients in a small saucepan. Scrape seeds from vanilla bean; stir seeds into broth mixture, reserving the bean for another use. Bring to a boil. Reduce heat, and simmer until reduced to 1/2 cup (about 20 minutes). Stir in 1/4 teaspoon salt.
Arrange chicken in a single layer in the bottom of a roasting pan coated with cooking spray. Sprinkle chicken evenly with remaining 1/2 teaspoon salt and pepper. Bake at 450? for 10 minutes.
Brush half of broth mixture over chicken; bake 5 minutes. Brush remaining broth mixture over chicken; bake 15 minutes or until a thermometer registers 180?. Garnish with orange rind, if desired.
