This classic French dish is easier to make than you might think, and the results are incredibly rewarding. This guide will walk you through each step, ensuring you achieve a delicious and authentic French onion soup.
Ingredients You'll Need:
This recipe makes about 6 servings of this delectable soup. Adjust accordingly if you need to make more or less!
- 3 pounds yellow onions, thinly sliced (about 6 large onions). The quality of your onions truly matters here – aim for sweet, flavorful ones.
- 6 tablespoons (3 ounces) unsalted butter, plus more for greasing the ramekins (optional). Don't skimp on the butter – it's crucial for the caramelization process!
- 1 teaspoon sugar (optional, helps with caramelization).
- 1/2 teaspoon salt, plus more to taste.
- 1/4 teaspoon black pepper.
- 1/2 cup dry sherry or dry white wine (optional, but adds depth of flavor).
- 8 cups beef broth (low sodium is best, so you can control the seasoning). Homemade is amazing, but store-bought works fine.
- 2 sprigs fresh thyme.
- 2 bay leaves.
- 1 baguette, sliced into 1/2-inch thick rounds.
- 1 cup grated Gruyère cheese (or Swiss cheese).
Step-by-Step Instructions:
1. Caramelizing the Onions: The Heart of the Soup
This is the most time-consuming, but also the most crucial, step. Patience is key!
- Melt the butter in a large, heavy-bottomed pot or Dutch oven over medium heat. The pot needs to be large enough to hold all the onions comfortably.
- Add the onions and sugar (if using) and cook, stirring occasionally, for at least 30-45 minutes, or until deeply caramelized. This is where the magic happens! The onions should be a rich, dark brown color. Don't rush this process; low and slow is the way to go. If the onions start to stick, add a tablespoon or two of water to deglaze the pot.
- Season with salt and pepper towards the end of the caramelization process.
2. Building the Flavor:
- Add the sherry or wine (if using) to the pot and scrape up any browned bits from the bottom. Let it simmer for a few minutes to cook off the alcohol.
- Pour in the beef broth, add the thyme and bay leaves, and bring the mixture to a simmer. Reduce heat and let it simmer gently for at least 30 minutes, allowing the flavors to meld.
3. Assembling and Baking:
- Preheat your oven to 375°F (190°C).
- Ladle the soup into oven-safe bowls or ramekins.
- Top each bowl with a slice of baguette and a generous amount of Gruyère cheese.
- Bake for 10-15 minutes, or until the cheese is melted, bubbly, and golden brown.
4. Serving and Enjoying:
- Carefully remove the soup from the oven and let it cool slightly before serving. This soup is best enjoyed hot and fresh.
Tips for the Best French Onion Soup:
- Use good quality ingredients: The better your onions and broth, the better your soup will taste.
- Don't rush the caramelization: This is the key to a truly delicious French onion soup.
- Adjust seasoning to your taste: Taste the soup before adding the cheese and adjust the salt and pepper as needed.
- Experiment with different cheeses: While Gruyère is traditional, other cheeses like Swiss or Fontina also work well.
