Preheat an oven to 325 degrees F (165 degrees C).
Remove the plastic netting and wrap from the turkey roast, plus the neck and bag of giblets stuffed inside. NOTE: This turkey has already been brined, so once you get it out of the packaging just pat dry with paper towels. Place turkey on a baking rack on a baking sheet or roasting pan. Cut oranges and lemons in half and stuff them inside the cavity of the turkey and set aside.
Mix together the maple syrup, rosemary, paprika, salt, pepper, garlic powder, and thyme, in a bowl, stirring to combine well. Brush 1/2 of the syrup mixture all over the turkey roast.
30 minutes into baking, baste the turkey with juices in the pan + 1/2 of the maple mixture remaining.
60 minutes into baking, baste the turkey with juices in the pan + 1/2 of the maple mixture remaining.
Place the roast, skin side up, on a baking rack set in a roasting pan. Roast in the preheated oven, basting occasionally until the roast is golden brown and a meat thermometer inserted into the center of the roast reads 170 degrees F (75 degrees C). Wrap the roast in foil, and let stand 10 minutes before removing the string netting for slicing.
