How to Make It
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.
