French onion soup is a traditional dish made from onions, beef broth, and wine. The onions are slowly caramelized to release their sweetness, creating a rich and flavorful base. The soup is typically served with toasted bread and melted Gruyère cheese on top, then broiled to a golden, bubbly finish.
French onion soup takes time to make, primarily due to the slow caramelization process of the onions. Expect to spend about 40 minutes caramelizing the onions, followed by 30 minutes of simmering the soup. Overall, the entire process takes about 1 to 1.5 hours. It’s well worth the wait, as the flavors deepen over time.
The process of making French onion soup is a rewarding one, especially as the rich aroma of caramelized onions fills the kitchen. When layering the soup with bread and cheese, it’s exciting to see the cheese melt perfectly, creating a golden, bubbly topping. Each bite is a comforting experience, with the sweetness of the onions balancing the savory broth and crispy bread. The dish is truly a crowd-pleaser, perfect for family dinners or special occasions.

Ingredient Notes for a French Onion Soup

- Beef Broth: Provides the rich, savory foundation for the soup. Beef broth enhances the flavor, making the soup hearty and flavorful.
- Dry White Wine: Adds acidity and balance to the richness of the broth. It also helps deglaze the pan, picking up any flavorful bits left from caramelizing the onions.
- Thyme Leaves: Adds an aromatic, earthy flavor to the soup. Fresh thyme brings a mild, fragrant note, while dried thyme works as a good substitute.
- Bay Leaves: Used to infuse the broth with a subtle, herby flavor. Remember to remove them before serving.
- Salt and Pepper: Essential for seasoning. Salt brings out the flavors of the broth and onions, while pepper adds a mild spice.
- French Baguette: A crunchy topping that contrasts perfectly with the creamy soup. Toast the baguette slices before placing them on top of the soup.
- Gruyère Cheese: A classic choice for French onion soup. Gruyère melts beautifully and has a slightly nutty, savory flavor that adds richness to the dish.
