Add the vegetable broth, kosher salt, black pepper, fresh rosemary, and fresh thyme to a large pot.
Bring the mixture to a boil (make sure all the kosher salt has dissolved). Then remove the pot from the heat and let the brining mixture cool for 15 minutes.
Add the cold water and ice to the brine.
Place the fully defrosted turkey breast side up in a container large enough to hold the turkey (that will fit in your fridge).
Add the brining mixture to the container, then add enough cold water to cover the whole turkey. Cover the container with plastic wrap and refrigerate for 18-24 hours.
Remove the turkey from the brine, making sure to get rid of any excess liquid. Then pat dry with paper towels.
Add the garlic powder, onion powder and black pepper to a small bowl, then mix to combine.
Season the turkey with the seasoning mixture, then add the onions, lemons, and orange quarters to the cavity of the turkey.
Place your turkey in an aluminum pan or baking dish.
Preheat your smoker to 275 degrees. Let the turkey come to room temperature while the smoker preheats. This will help them cook more evenly.
When the smoker has reached 275 degrees F. add your favorite wood chips to the smoker tube. I used a combination of hickory and cherry wood chips
Place the turkey in the smoker on a rack. For a bird this size I like to cook it in an aluminum pan (or roasting pan) it is easier to manage, you’ll have less clean up, and you’ll be able to collect the drippings to use make gravy. *Alternatively, you can place the turkey directly on the smoker rack with a drip pan underneath to catch the drippings Place a temperature probe (or meat thermometer) into the thickest part of the turkey thigh being careful not to hit the thigh bone.
When the internal temperature of the turkey reaches 150 degrees F. wrap the end of the leg bones with foil this will help the skin from shrinking up the leg. Then cover the entire turkey with aluminum foil.*At this point, the turkey has taken on as much smoke flavor as it can, and this step will help keep it moist as it finishes cooking. When the internal temperature of the turkey reaches 165 degrees, remove it from the smoker.*Remember we are cooking for an internal temperature of 165 degrees. Cooking times will vary depending on the turkey size and the smoker type. After removing the smoked turkey from the smoker, let it rest for 30 minutes before slicing. This will give the juices time to redistribute throughout the turkey.
Serve the turkey with roasted potato wedges or smashed buttery potatoes, green beans (or your favorite vegetable), turkey gravy, and cranberry sauce.Store any turkey leftovers in an airtight container for 4-5 days. To store in the freezer, double wrap with plastic wrap, then store in a ziplock bag in your freezer for up to 2 months. make sure your begin to defrost your turkey at least 48 hours in advance of placing it in the brine a whole turkey is a large bird and needs time that properly place it in an aluminum tray in your refrigerator after the first 24 hours flip your turkey over so both sides can thaw properly once your turkey is defrosted remove all turkey parts from the cavity to make sure no paper is left behind
