Preheat oven to 250 degrees, place rack in the lower-middle position.
Heat 2 cups of water in the microwave for 3 minutes. Place in the corner of the oven.
Place the trussed chicken into a skillet, baking dish or roasting pan, make sure there's enough room around the chicken so that nothing drips out, and that it is deep enough to catch the juices.
Rub the melted butter on the skin. In a small mixing bowl combine the seasonings and spices, then rub on the buttered skin. You can gently lift up on the skin around the breasts and rub some seasoning under there too.
Place in the oven and bake for 3-4 hours (depending on the size of the chicken), basting twice during that time. Remove when a thermometer inserted into the thigh reaches 160 degrees. Allow to rest for 10 minutes before transferring to a cutting board and carving.
Notes
-For a slow cooker: cover and cook on low for 6-8 hours, or on high for 4-5 hours.
