Ingredients

For the Soup:

• Olive Oil: 2 tablespoons, plus more for drizzling
  Olive oil helps to sauté the onions, adding a rich, smooth flavor to the soup.
• Butter: 1/2 cup (1 stick)
  Butter is essential for caramelizing the onions, giving them a sweet, golden finish.
• Onions: 3 large, finely sliced
  Onions are the star of this dish, providing a sweet, caramelized flavor base.
• Garlic: 1 clove, finely sliced
  Garlic adds an aromatic depth to the soup.
• White Wine: 3/4 cup
  White wine deglazes the pan and adds acidity to balance the richness of the broth.
• All-Purpose Flour: 1 tablespoon
  Flour is used to slightly thicken the soup, giving it a more substantial texture.
• Brandy: 1 3/4 tablespoons
  Brandy adds a deep, warming flavor to the broth, enhancing the soup’s complexity.
• Fresh Thyme: 5 sprigs, leaves picked, plus more for garnish
  Thyme adds a subtle earthiness and pairs perfectly with the onions and broth.
• Beef Stock: 4 cups
  Beef stock forms the rich, flavorful base of the soup.

For Serving:

• Bread Bowls: 2 round
  Bread bowls add a rustic touch and absorb the rich broth, making each bite flavorful.
• Gruyère Cheese: 16 slices
  Gruyère cheese, known for its melting qualities, creates a delicious, gooey topping.
• Salt and Freshly Ground Black Pepper: To taste
  Season the soup to enhance and balance the flavors.

Instructions

1. Caramelize the Onions:

• Heat 2 tablespoons of olive oil and 1/2 cup of butter in a large, heavy-bottomed pot over medium heat.
• Add the finely sliced onions and cook, stirring frequently, until they become soft and golden brown, about 25-30 minutes. This slow caramelization process is crucial to developing the sweet, deep flavor of the onions.
• Add the sliced garlic to the onions during the last 5 minutes of cooking, ensuring it becomes fragrant without burning.

2. Deglaze and Build the Broth:

• Pour the white wine into the pot with the onions, stirring to deglaze the pan and lift any caramelized bits stuck to the bottom. Allow the wine to reduce by half.
• Sprinkle the flour over the onion mixture and stir to coat. Cook for another 2-3 minutes to eliminate the raw flour taste.
• Stir in the brandy and cook for another 2 minutes.
• Add the fresh thyme leaves and beef stock, stirring to combine. Bring the soup to a gentle simmer and let it cook for 20-25 minutes to allow the flavors to meld together. Season with salt and freshly ground black pepper to taste.

3. Prepare the Bread Bowls:

• Preheat your oven to 350°F (175°C).
• Cut the tops off the round bread bowls and carefully hollow out the insides, leaving a thick enough wall to hold the soup without leaking.
• Place the bread bowls on a baking sheet and drizzle the insides lightly with olive oil. Toast them in the oven for 10-12 minutes, or until the bowls are slightly crisp and golden.

4. Assemble and Serve:

• Ladle the hot soup into the prepared bread bowls, filling them almost to the top.
• Place 2-3 slices of Gruyère cheese on top of each filled bread bowl.
• Return the bread bowls to the oven and bake for an additional 10-15 minutes, or until the cheese is melted, bubbly, and golden brown.
• Remove from the oven and garnish with a few fresh thyme leaves.

5. Serve Immediately:

• Serve the French Onion Soup in the bread bowls hot, allowing the bread to soak up the flavorful broth as you enjoy the soup. The combination of the rich soup, the melted cheese, and the crispy, soft bread makes for a truly comforting meal.

Tips and Tricks

• Caramelization is Key: Take your time when caramelizing the onions. The slower you cook them, the sweeter and richer they will become. This step cannot be rushed, as it’s essential for achieving the deep flavor that makes French Onion Soup so delicious.
• Choose the Right Bread: When selecting bread bowls, opt for a crusty, sturdy bread like sourdough. It will hold up well to the soup without becoming too soggy too quickly.
• Make-Ahead Option: The soup can be made ahead of time and reheated when ready to serve. Simply reheat it on the stove before ladling it into the bread bowls and topping with cheese.
• Vegetarian Version: For a vegetarian option, you can substitute the beef stock with vegetable stock and omit the brandy. The soup will still be flavorful and satisfying.

Frequently Asked Questions

1. Can I use a different type of cheese?
   • Yes! While Gruyère is traditional, you can use Swiss, Emmental, or even a sharp cheddar. Each cheese will bring a different flavor to the dish.
2. What can I do with the leftover bread from the bread bowls?
   • The bread you hollow out can be turned into croutons! Simply cube it, toss with a little olive oil, and bake until crispy. They make a great topping for salads or even more soup.
3. Is there a way to make this soup gluten-free?
   • Absolutely. Use a gluten-free flour to thicken the soup and serve it in a gluten-free bread bowl or a regular bowl if gluten-free bread is not available.
4. How do I store leftovers?
   • Store the soup separately from the bread bowls. The soup can be refrigerated for up to 3 days or frozen for up to 3 months. Bread bowls are best eaten fresh, but can be stored in an airtight container for a day or two.
