Preheat oven to 350. In a 9 X 13 glass baking dish, place turkey thighs skin side up.
Sprinkle with paprika and arrange onion slices over turkey.
In a small bowl, combine orange juice, brown sugar, cornstarch, ginger and parsley; mix well. Pour sauce evenly over turkey; cover and bake for 1 1/2 hours until thighs are tender and juices run clear when tested with a knife.
