Calories In French Onion Soup

French onion soup is a comforting classic, often enjoyed as a savory starter to meals or a warm treat on chilly evenings. But if you're watching your calorie intake, you might be wondering: "How many calories are in French onion soup?" The answer depends on the recipe, portion size, and accompanying ingredients like cheese and bread.

Calories in French Onion Soup:
For a traditional bowl (about one cup) of homemade French onion soup without toppings, the calorie count is usually around 150-200 calories. Most of the calories come from the caramelized onions, beef broth, and a small amount of butter or olive oil used during preparation.

However, it’s the cheesy topping and bread (or croutons) that can significantly increase the calorie count. Topped with a slice of baguette and a generous layer of melted Gruyère cheese, a single serving can jump to 300-400 calories or more. Restaurant versions are often on the higher end due to larger portion sizes and additional butter or cheese.

If you're making French onion soup at home, consider using low-calorie substitutions like reduced-fat cheese, whole-grain bread, or vegetable broth to keep the calories in check. These swaps can make the dish a lighter but equally flavorful option.
