Whether you’re preparing it for a special occasion or just as a treat for yourself, this classic French Onion Soup recipe will leave you coming back for more.

Ingredients:

• 4 large onions (yellow or sweet onions work best), thinly sliced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 teaspoon salt
• 1 teaspoon sugar (helps with caramelization)
• 3 cloves garlic, minced
• 1/4 cup dry white wine (or dry sherry)
• 6 cups beef broth (or vegetable broth for a vegetarian version)
• 2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
• 2 bay leaves
• Freshly ground black pepper, to taste
• 1 tablespoon brandy or cognac (optional)
• 8 slices of French baguette, toasted
• 2 cups Gruyère cheese, grated (Swiss cheese works too)

Instructions:

Step 1: Caramelize the Onions Start by melting the butter and olive oil in a large pot or Dutch oven over medium-low heat. Add the sliced onions, salt, and sugar. The sugar will help the onions caramelize and develop a deep, sweet flavor. Cook the onions for about 45 minutes, stirring occasionally. The key to perfect French Onion Soup is the slow caramelization of the onions, so be patient. The onions should be golden brown and soft by the end of this process.

Step 2: Add Garlic and Wine Once the onions are perfectly caramelized, add the minced garlic and cook for about 1 minute, until fragrant. Pour in the white wine (or dry sherry), scraping up any browned bits from the bottom of the pot. This step will add depth and flavor to the soup.

Step 3: Simmer the Broth Add the beef broth, thyme, and bay leaves to the pot. Bring the soup to a gentle simmer, then cover and cook for 30-40 minutes. This allows the flavors to meld together and the broth to absorb the caramelized sweetness of the onions. Stir occasionally and adjust the seasoning with salt and pepper as needed. If you like a little extra richness, add a tablespoon of brandy or cognac at this stage.

Step 4: Prepare the Toasted Bread While the soup is simmering, preheat your oven to 375°F (190°C). Lay the baguette slices on a baking sheet and toast them in the oven for about 10 minutes or until they are golden and crispy. You can rub each slice with a garlic clove before toasting for extra flavor.

Step 5: Assemble the Soup Once the soup has finished simmering, discard the bay leaves. Ladle the soup into oven-safe bowls and place a slice or two of the toasted baguette on top of each bowl. Then, generously sprinkle the grated Gruyère cheese (or Swiss cheese) over the bread.

Step 6: Broil and Serve Place the soup-filled bowls under the broiler for 3-5 minutes or until the cheese is melted and bubbly with a golden-brown crust. Keep an eye on it to ensure the cheese doesn’t burn.

Remove from the oven, garnish with a few sprigs of fresh thyme, and serve immediately.

Tips for the Perfect French Onion Soup:

1. Caramelize Slowly: The key to a great French onion soup is in the caramelization of the onions. Take your time—don’t rush this step. It’s worth the wait for that rich, sweet flavor.
2. Broth Matters: Use a good-quality beef broth for the best flavor. Homemade is always better, but store-bought low-sodium beef broth can also work in a pinch.
3. Add Wine and Brandy: The wine and brandy deepen the flavor of the soup, so don’t skip these ingredients. If you prefer a non-alcoholic version, you can substitute the wine with a splash of balsamic vinegar or apple cider vinegar for a tangy twist.
4. Cheese: Gruyère is traditional, but Swiss cheese, Comté, or even provolone can be used if you’re looking for a variation. The key is to use a cheese that melts well.
5. Vegetarian Option: For a vegetarian French onion soup, simply substitute the beef broth with vegetable broth, and the flavor will still be amazing!
