Preheat the oven to 350°F (175°C). Line a roaster with sheets of aluminum foil long enough to wrap around turkey.
Stir together parsley, rosemary, sage, thyme,lemon-pepper seasoning, and salt in a small bowl.
Rub herb mixture into the turkey cavity, then stuff with orange wedges, onion, carrot and celery. Tie the legs together with kitchen string, then tuck the wings under the body. Place turkey on the foil in the roasting pan.
Pour champagne and chicken broth over turkey, making sure to get some liquid in the cavity. Bring aluminum foil up and ove rthe top of turkey and seal; try to keep the foil from touching the turkey.
Roast turkey in the preheated oven until juices run clear, 2-1/2 to 3 hours. Uncoverturkey and continue baking until the skin turns golden brown, 30 to 60 more minutes. An instant-read thermometer inserted into the thickest part of thigh, near the bone, should read 180°F (82°C).
Remove turkey from the oven, cover with two sheets of aluminum foil, and allow to rest in a warm area before slicing, 10 to15 minutes.
