Cut your celery, carrots, onion, and garlic. Add ⅔ of them to the bottom of your roasting pan.
*Note: Be sure to use a roasting pan with an elevated rack to keep the bird somewhat above the liquid.
Prepare the turkey by removing the added items (neck, giblets, gravy packet) - no need to rinse the turkey - leave the tie on the legs - this helps keep it together.
Place the turkey in the prepared pan and stuff the remaining veggies inside the turkey.
Add one apple, cut in half, inside the turkey.
Place remaining apples (also cut in half) around outside of the turkey.
Cut the butter into 1 tablespoon pats. Carefully lift skin away from meat and slide pats of butter between the skin & breast.
Add chicken stock to the bottom of the pan.
Melt the compound butter and brush over the entire turkey.
Roast in preheated oven, uncovered for 30 minutes.
Remove, baste, tent with foil - return to oven.
