Chicken And French Onion Soup Recipe

Step 1: Caramelize the Onions

In a large pot over medium heat, melt the butter with the olive oil. Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for about 40 minutes until the onions are deeply golden and caramelized. This slow process is key to developing the soup’s rich flavor.

Step 2: Cook the Chicken

Add the diced chicken to the pot with the caramelized onions. Cook over medium heat until the chicken is no longer pink, about 5-7 minutes. Season with salt and pepper to taste. Tip: For extra flavor, you can brown the chicken in a separate pan before adding it to the onions.

Step 3: Add Broths and Herbs

Pour in the chicken and beef broths, then add the thyme and bay leaf. Bring the mixture to a simmer and let it cook for about 20 minutes to allow the flavors to meld together. Remove the bay leaf before serving.

Step 4: Prepare the Bread and Cheese Topping

While the soup simmers, toast the slices of crusty bread until golden. Ladle the soup into oven-safe bowls, top each with a slice of toasted bread, and sprinkle generously with shredded Gruyere cheese.

Step 5: Broil to Melt the Cheese

Place the bowls under the broiler for 2-3 minutes, or until the cheese is bubbly and slightly browned. Watch closely to prevent burning. Serve immediately, enjoying the gooey cheese and rich flavors.

Tips and Tricks

For an even deeper flavor, consider caramelizing the onions for up to an hour. The longer they cook, the sweeter and more flavorful they become. If you’re short on time, you can speed up the process by adding a pinch of sugar to the onions. Another tip is to use a mix of cheeses for the topping, such as mozzarella for stretchiness and Parmesan for a salty kick. Lastly, for a gluten-free version, simply omit the bread or use a gluten-free alternative.

Recipe Variations

  • Vegetarian Version: Omit the chicken and use vegetable broth instead of chicken and beef broths. Add mushrooms for umami flavor.
  • Spicy Twist: Add a pinch of red pepper flakes or a dash of hot sauce to the soup for some heat.
  • Creamy Version: Stir in a half cup of heavy cream or coconut milk for a richer, creamier texture.
  • Different Cheeses: Experiment with different cheeses like Swiss, provolone, or even blue cheese for a unique flavor profile.

Frequently Asked Questions

Can I make this soup ahead of time?

Absolutely! You can caramelize the onions and cook the soup base ahead of time. Store it in the refrigerator for up to 3 days. When ready to serve, reheat the soup, prepare the bread and cheese topping, and broil as directed.

What’s the best type of onion to use?

Yellow onions are ideal for caramelizing due to their balance of sweetness and pungency. However, you can also use white onions or a mix of different types for a more complex flavor.

Can I freeze this soup?

Yes, but it’s best to freeze the soup before adding the bread and cheese topping. The texture of the onions may change slightly upon thawing, but the flavor will still be delicious. Reheat gently on the stove before serving.
