What’s the Difference Between Italian and French Onion Soup

French onion soup is traditionally made with slowly caramelized onions, beef broth and a thick layer of bread with melted Gruyère cheese, giving it a rich, savoury depth. I love it! But it takes time to caramelize the onions just right.

This Italian-inspired version, based loosely on Tuscan Licurida (made with regional red onions called Tropea onions) incorporates shredded potatoes. In this soup, the onions are softened, not caramelized. This makes it faster to make, keeps it lighter and more delicate compared to the deep, sweet flavours of caramelized onions found in French onion soup. This soup also includes shredded potatoes for thickness and a little heartiness. It uses a simple broth, herbs and a sprinkling of cheese. The result is a simpler, herb-infused soup that’s hearty without being overly heavy.

Not having access to Tropea onions, I make this soup with either yellow or red onions – sometimes a combination of the two. For a sweeter flavour try using Vidalia onions when they’re in season.

Use a good quality veggie or beef stock to add to the shredded potatoes and softened onions.

Tips for Success:

  • Use Starchy Potatoes: Russet or Yukon Gold potatoes work best as they help thicken the soup naturally.
  • For Extra Creaminess: Blend a portion of the soup before serving or stir in a splash of heavy cream.
  • Enhance the Flavour: Add a dash of white wine when cooking the onions for a subtle depth of flavour. And consider a pinch of hot pepper flakes.
  • Make It a Meal: Pair with crusty Italian bread or a fresh green salad for a complete meal.

Storing & Reheating:

  • Freeze: Freeze for up to 3 months in a freezer-safe container. Thaw overnight in the fridge before reheating.
  • Reheat: Warm on the stovetop over medium heat, adding a splash of broth if needed to adjust consistency.

Notes

*Onions: Choose red, white, yellow, Vidalia, or a combination for a slightly different flavour, colour and sweetness every time. In this recipe, onions do not need to be caramelized, but if you prefer to bring out their full sweetness by caramelizing, that’s always an option.
Leftovers: Store leftovers in an airtight container in the fridge for up to 4 days. Freeze for up to 3 months in a freezer-safe container.
