In the kitchen and how to use it
Condensed onion soup is a pantry staple, diluted with water or milk and heated as a simple soup, or used undiluted as the base for French onion soup once broth, toasted bread, and cheese are added. It also mixes into casseroles and pot roasts for flavor, and is the classic base for a sour cream onion dip served with chips or vegetables.
Unopened cans keep in the pantry; once opened, refrigerate any remaining soup in a sealed container and use it within a few days. At just 46 calories per 100g it is a low-calorie base, though sodium runs high at 516mg per 100g, so even a diluted cup serving (123g) carries a notable amount. It works best as a flavor base for casseroles and dips rather than a standalone meal.
