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 the oil, and then sprinkle with the salt and pepper.

Arrange the turkey pieces, skin-side up, on a baking sheet with the thick end of breasts and thighs at the corners and 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 the drippings from burning and roast the turkey for 20 more minutes, covering loosely with foil if browning too quickly, until an instant-read thermometer registers 165 to 170 degrees F in the thickest part of the thigh.

Transfer the turkey to a platter. Brush generously with more glaze and let rest for 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. In a heavy, medium saucepan, heat the degreased pan juices over medium-high heat. Whisk 2 to 3 tablespoonfuls of the glaze into the pan juices to make the gravy and bring to a simmer for the flavors to blend.

Slice the turkey and arrange on the platter. Garnish with the herb sprigs, orange wedges, and cranberries. Serve the turkey with the gravy.
