Position an oven rack in the bottom third of the oven and preheat to 400°F (204°C).
Pat the turkey pieces thoroughly dry with paper towels. Brush them evenly with olive oil and season with kosher salt and freshly ground black pepper.
Arrange the turkey pieces skin-side up on a large rimmed baking sheet. Position the thicker breast and thigh pieces toward the corners and the drumsticks closer to the center.
Roast for approximately 1 hour and 10 minutes.
While the turkey roasts, prepare the glaze. Add the orange juice concentrate, cranberry juice concentrate, orange marmalade, and rosemary to a small saucepan. Bring to a boil over medium-high heat.
Cook the mixture for about 15 minutes, whisking regularly, until it reduces enough to lightly coat the back of a spoon.
Remove from the heat and whisk in the butter. Season with 1/4 teaspoon kosher salt and 1/8 teaspoon black pepper. Set aside.
Remove the turkey from the oven and generously brush the pieces with Cranberry-Orange Glaze. Carefully pour the chicken broth onto the baking sheet around the turkey to keep the pan drippings from burning.
Return the Cranberry Orange Glazed Turkey to the oven and roast for approximately 20 minutes more. Loosely cover with foil if the skin begins to brown too quickly.
Check the turkey with an instant-read thermometer inserted into the thickest areas without touching bone. The turkey should reach a safe minimum internal temperature of 165°F (74°C).
Transfer the cooked turkey pieces to a serving platter. Brush with additional glaze and let rest for 25–30 minutes before slicing.
Meanwhile, carefully transfer the pan juices and browned bits to a measuring cup. Allow the fat to rise, then spoon it from the surface.
Pour the remaining pan juices into a medium saucepan. Place over medium-high heat and whisk in 2–3 tablespoons of cranberry orange glaze, adding more to taste.
Bring the gravy to a gentle simmer, stirring until the flavors combine and the gravy is heated through.
Slice the rested turkey and arrange it on a platter. Garnish with fresh herb sprigs, orange wedges, and whole cranberries. Serve warm with the cranberry-orange gravy.
