1. Preheat the oven to 325 degrees F (165 degrees C).

2. Stir onion, roasted red peppers, whiskey, and garlic together in a bowl. Place mixture inside turkey cavity. Mince chipotle peppers in a food processor until about the consistency of spaghetti sauce. Rub 1/2 of the chipotles on the outside of the turkey, and place the rest inside the cavity. Place turkey into a roasting bag, close the bag according to the directions, and place into a roasting pan.

3. Bake in the preheated oven until no longer pink at the bone and the juices run clear, about 3 1/2 hours. An instant-read thermometer inserted into the thickest part of the thigh, near the bone should read at least 165 degrees F (74 degrees C). Remove from the oven and let rest in a warm area for 10 to 15 minutes before slicing.

Tips

I recommend making the turkey a day in advance. Then you can chop the turkey into chunks, put it into a crock pot and fill the remaining space with the turkey broth. Heat on Low until heated through, about 2 hours.
