Rather than using a mixture of salt, pepper, garlic and onion powders, and paprika which comprise the rub for the exterior of the chicken, you can use poultry seasoning. It's often a mixture of the aforementioned ingredients and should work fine as long as you use it quite generously. At least 3-4+ teaspoons, if not more. Because my homemade dry rub uses 8 teaspoons of ingredients. You want to make sure to season properly for optimal flavor of the finished recipe!
