How to Make French Onion Soup
Follow these simple steps to make your own French onion soup:
Step 1: Caramelize the Onions
In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions, salt, and sugar. Cook, stirring occasionally, for 40-45 minutes, until the onions are deeply caramelized and golden brown.
Step 2: Add the Broth and Simmer
Once the onions are caramelized, add the wine (if using) and scrape any bits off the bottom of the pot. Pour in the broth, add the bay leaf and thyme, and bring to a simmer. Let it simmer for 30 minutes, allowing the flavors to meld together. Remove the bay leaf and thyme.
Step 3: Toast the Baguette
While the soup is simmering, preheat your oven to 350°F (175°C). Place the baguette slices on a baking sheet and toast in the oven for 5-7 minutes or until golden and crispy.
Step 4: Assemble and Serve
Ladle the soup into oven-safe bowls. Place a slice of toasted baguette on top of each bowl, then sprinkle with the grated cheese. Place the bowls under a broiler for 2-3 minutes, or until the cheese is melted and bubbly.
Step 5: Serve and Enjoy
Serve the soup hot, with the cheese still bubbling and the bread slightly toasted. Enjoy the warm, comforting layers of flavor!
Tips for Perfecting Your French Onion Soup
- Slow Caramelization: Don’t rush the caramelization process. The more slowly you cook the onions, the sweeter and more flavorful they will become.
- Broth Quality: Use a high-quality broth (beef broth works best for richness), or make your own if possible.
- Crusty Bread: Choose a firm, crusty bread for the topping, like a baguette, to prevent it from becoming soggy.
Serving Suggestions for Your French Onion Soup
- Pair with a Salad: Serve with a light green salad to balance out the richness of the soup.
- Perfect for Dinner Parties: This soup makes an impressive start to any meal, especially paired with a glass of wine.
- Enjoy with a Side of Bread: Serve with extra toasted baguette slices for dipping.
