Baked Chicken with Orange Juice

1 chicken, quartered or 3 lbs parts (I prefer to use boneless skinless chicken breasts)
4 tsp Dijon mustard
1/2 c. finely chopped onions
2 Tbsp unsalted butter, cut into bits
salt and pepper
1 1/2 c. orange juice
1/4 c. firmly packed dark brown sugar

Preheat oven to 375. Smear chicken with Dijon mustard. Arrange in shallow baking dish or roasting pan just large enough to hold it in a single layer (skin down if it has skin). Sprinkle pieces with onion, butter, and salt and pepper. Pour orange juice around the chicken. Bake for 30 minutes, basting once. Turn over and sprinkle with brown sugar. Bake until chicken is tender and golden- 15 to 20 minutes more.

Add more orange juice if the pan seems dry. Remove chicken to a serving platter. Pour juices into a small saucepan and boil over high heat until syrupy. Spoon sauce over the chicken and serve.
