Ingredients: The Foundation of Your Masterpiece

Before we begin, let's gather our ingredients. For this classic French onion soup, you'll need:

• 4 large onions (yellow or sweet)
• 3 tablespoons butter
• 1 tablespoon olive oil
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon sugar (optional, to help with caramelization)
• 1 tablespoon flour
• 8 cups beef broth
• ½ cup dry white wine (optional, but adds depth of flavor)
• 1 baguette, sliced
• 2 cups grated gruyere cheese
• Fresh thyme and bay leaves for garnish

The Art of Caramelizing Onions

Caramelized onions are the heart and soul of French onion soup. This process may take time, but patience is key. Think of it as a slow dance, where the onions and heat gradually become acquainted, resulting in a sweet, golden union.

1. Slice your onions thinly. The thinner they are, the quicker they'll cook.
2. Heat the butter and olive oil in a large pot over medium heat. Add the onions, salt, pepper, and sugar (if using).
3. Stir to coat the onions evenly with the butter and oil.
4. Cook the onions, stirring occasionally, for about 30-40 minutes. They should turn a beautiful golden brown and reduce significantly in volume.

Building the Broth: The Soul of the Soup

With your caramelized onions ready, it's time to build the broth. This is where the soup gains its depth and complexity.

1. Sprinkle the flour over the caramelized onions and cook for another 2-3 minutes, stirring constantly. This will help thicken the soup slightly.
2. Deglaze the pot with the white wine (if using). Scrape up any browned bits from the bottom—they're pure flavor!
3. Add the beef broth, thyme, and bay leaves. Bring the soup to a boil, then reduce the heat and let it simmer for at least 30 minutes. This allows the flavors to meld together beautifully.

The Pièce de Résistance: Crusty Bread and Gruyere Cheese

No French onion soup is complete without the iconic duo of crusty bread and melted gruyere cheese. It's like the crown atop a royal dish, adding texture and richness.

1. Preheat your oven to 350°F (180°C).
2. Arrange the baguette slices on a baking sheet and toast them in the oven for about 5-7 minutes, or until they're golden and crisp.
3. Ladle the soup into oven-safe bowls. Place a few toasted baguette slices on top of each bowl.
4. Sprinkle the grated gruyere cheese generously over the bread. Make sure to cover the entire surface—the more cheese, the merrier!
5. Broil the soup under the preheated broiler for 2-4 minutes, or until the cheese is melted, bubbly, and slightly golden.

Serving Your Masterpiece

Your classic French onion soup is now ready to be served. Be careful, as the bowls will be hot. Garnish with a sprig of fresh thyme for a touch of elegance. Pair your soup with a simple green salad and a glass of French wine for a truly authentic experience.
