Au Gratin vs Scalloped Box Mixes: What Is Actually in the Ingredients?
By David Miller
The most consequential nutritional factor in boxed potato casserole mixes is sodium content. In a homemade gratin, a cook controls the salt shaker, seasoning layers against rich dairy fats. In commercial production, salt operates as both a primary flavor carrier and a preservative agent, compensating for volatile aromatics lost during dehydration.
A typical prepared serving measures just one-half cup, a portion far smaller than what most diners spoon onto holiday dinner plates. Within that single half-cup, sodium levels frequently cross 600 mg. When factored across an average dinner containing cured ham or glazed turkey, a diner can easily consume their full daily sodium allocation in one sitting.
