Ingredients for the Perfect French Onion Soup Recipe

To make French onion soup, you’ll need just a few simple ingredients. Here’s what you’ll need for 4 servings:

For the Soup:

• 4 large yellow onions, thinly sliced
• 4 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 cloves garlic, minced
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
• 1 bay leaf
• 1 cup dry white wine (optional, but recommended)
• 4 cups beef broth (or vegetable broth for a lighter version)
• 2 cups chicken broth
• Salt and pepper, to taste
• 1/4 teaspoon sugar (to help caramelize the onions, optional)

For the Topping:

• 4 slices of baguette (or French bread)
• 2 cups shredded Gruyère cheese (or Swiss cheese)

Step-by-Step French Onion Soup Recipe

Now that you have your ingredients ready, let’s walk through the process of making this comforting soup from scratch.

Step 1: Caramelize the Onions

Start by heating butter and olive oil in a large pot or Dutch oven over medium-low heat. Once the butter has melted, add the thinly sliced onions and a pinch of salt. Stir occasionally to ensure the onions cook evenly. This process takes time, but the key is to be patient. Cook the onions for about 40-45 minutes, stirring frequently. You want the onions to become deeply golden brown and caramelized. Add 1/4 teaspoon sugar halfway through cooking to help with the caramelization.

Step 2: Add Garlic and Herbs

Once the onions are caramelized, add the minced garlic and cook for an additional 1-2 minutes until fragrant. Then, add the fresh thyme and bay leaf, stirring to incorporate the flavors.

Step 3: Deglaze the Pan with Wine

Next, pour in white wine (if using), and scrape the bottom of the pot to release any caramelized bits stuck to the bottom. Let the wine simmer for about 5-7 minutes, allowing it to reduce slightly. This step adds depth of flavor to the soup.

Step 4: Add the Broth

Pour in the beef broth and chicken broth, and bring the mixture to a simmer. Allow the soup to cook for an additional 20-30 minutes, letting the flavors meld together. Season the soup with salt and pepper to taste, and discard the bay leaf before serving.

Step 5: Prepare the Bread Topping

While the soup simmers, prepare the bread topping. Preheat your broiler. Place the slices of baguette on a baking sheet and toast them under the broiler for 2-3 minutes, or until golden brown. You can also toast them in a skillet if you prefer.

Step 6: Assemble the Soup

Once the soup is ready, ladle it into oven-safe bowls. Place a slice of toasted baguette on top of each bowl of soup. Then, sprinkle a generous amount of shredded Gruyère cheese (or Swiss cheese) over the bread. Make sure the cheese covers the entire slice of bread.

Step 7: Broil the Soup

Place the bowls under the broiler for about 3-5 minutes, or until the cheese is bubbly and golden brown. Keep a close eye on it to ensure the cheese doesn’t burn.

Step 8: Serve and Enjoy!

Remove the bowls from the oven carefully (they will be hot!). Serve the French onion soup immediately, garnished with extra thyme if desired.
