This easy tuna casserole is quick to make. Perfect for the busy mom!
To elevate this quick casserole, consider substituting the processed American cheese with a blend of sharp cheddar and Monterey Jack for deeper flavor and superior melt. Finely dice the onion for a smoother texture and less raw bite. For an enhanced creamy consistency, a splash of whole milk or even a tablespoon of cream cheese can be incorporated with the soup. Ensure tuna is thoroughly drained to prevent a watery result. For a delightful textural contrast, briefly broil the finished casserole with a topping of buttered breadcrumbs or crushed crackers until golden and crisp. Always taste and adjust seasoning before serving, perhaps a touch of garlic powder or dried dill.
