Position an oven rack in the bottom third of the oven. Preheat the oven to 400 degrees F.
Rinse the turkey pieces and pat very dry with paper towels. Brush the turkey all over with oil, and sprinkle with salt and pepper. Arrange the turkey, skin-side up, on a baking sheet with the thick end of the breasts and thighs at the corners, the drumsticks in the center. Roast for 1 hour and 10 minutes.
Remove the turkey from the oven and brush with the Cranberry Orange Glaze. Pour the broth onto the baking sheet to prevent drippings from burning and roast the turkey, covering loosely with foil if browning too quickly, until an instant-read thermometer registers 165 degrees F to 170 degrees F in thickest part of the thigh (do not let the thermometer touch bone), 20 minutes.
Transfer the turkey to a platter. Brush generously with more glaze and let rest 25 to 30 minutes.
Meanwhile, scrape all the pan juices and browned bits from the baking sheet into a large measuring cup. Spoon off and discard the fat that rises to the surface. Heat the pan juices in a heavy medium saucepan over medium-high heat. Whisk 2 to 3 tablespoons of the glaze into the pan juices (or more if desired) to make the gravy and bring to a simmer for the flavors to blend.
Slice the turkey and arrange on the platter. Garnish with herb sprigs, oranges wedges and cranberries, and serve with gravy.
Cranberry Orange Glaze:
Yield:About 1 1/4 cups.
In a small saucepan, bring the cranberry juice, orange juice, marmalade and rosemary to a boil over medium-high heat. Boil until the glaze thickens enough to coat a spoon, whisking often, 15 minutes. Remove from the heat. Whisk in the butter, then season the glaze with salt and pepper.
