Cut 2 onions, 3 ribs of celery, and 2 carrots in large chunks.
Make a seasoning salt by blending blend 2 tablespoons kosher salt, 1 tablespoon black pepper, 1 tablespoons poultry seasoning. This is plenty for the largest turkey, and you'll have some leftover to use in the dressing, gravy, etc.
Let one stick of butter soften to room temperature, or make a flavored compound butter recipe, which is butter mixed with herbs and spices.
