Notes & Wine Advice
Recipe Notes
Take your time caramelizing the onions, as this step creates the deep, sweet flavor that makes this soup special. For the best cheese topping, broil the soup just until the cheese bubbles and turns lightly golden. Use Gruyère instead of Swiss cheese for an even richer, traditional flavor. Serve with a crisp green salad or extra crusty bread for a complete meal.Wine Advice
A glass of Sauvignon Blanc complements the sweet onions and rich broth beautifully. If you prefer red wine, a light Pinot Noir pairs wonderfully with the melted cheese and savory broth.Nutrition values
