How to Make French Onion Chicken Soup
Step 1: Sauté the Onions
Start by slicing your onions thinly. In a large pot over medium heat, melt 4 tablespoons of butter. Add the onions and cook them slowly until they turn golden brown—this takes about 30 minutes. Stir occasionally to prevent sticking. Sautéing brings out their natural sweetness, which is key to this soup’s rich flavor.
Step 2: Build Flavor
Once your onions are beautifully caramelized, add garlic, carrots, celery, thyme, bay leaves, salt, and pepper. Sauté for another 5 minutes until fragrant. This step layers even more flavor into your soup!
Step 3: Cook the Chicken
Next, add your chicken pieces into the pot along with grape juice and apple juice. Stir everything together so that each ingredient mingles well. Cover and let it simmer gently for about 20 minutes until the chicken is cooked through.
Step 4: Thicken It Up
After removing the chicken from the pot and shredding it (or cutting into bite-sized pieces), sprinkle flour over the vegetables while stirring constantly to avoid lumps. Slowly pour in the chicken broth while still stirring until everything is well combined.
Step 5: Final Touches
Return your shredded chicken to the pot along with any juices that may have collected. Simmer everything together for an additional 10-15 minutes to meld those wonderful flavors together.
Step 6: Serve and Enjoy!
Slice your baguette into thick pieces and toast them lightly under a broiler if desired. Ladle hot soup into bowls and top each serving with toasted bread and a generous handful of Gruyère cheese. Pop under the broiler again just until bubbly—then dig in!
And there you have it! A delightful bowl of French Onion Chicken Soup that’s sure to warm your heart and satisfy your cravings. Enjoy every spoonful!
Pro Tips for Making French Onion Chicken Soup
Creating the perfect French Onion Chicken Soup is a delightful journey, and with a few handy tips, you can elevate your dish to new heights!
-
Use fresh onions – Fresh yellow onions will provide the sweetest flavor and the best caramelization. This sweetness is key to balancing the savory chicken and broth flavors.
-
Don’t rush the caramelization – Allowing your onions to cook slowly over medium heat will develop their natural sugars. This step is crucial for achieving that rich, golden color and deep flavor that defines French onion soup.
-
Season in layers – Season your soup at each stage of cooking rather than all at once. This technique ensures every ingredient is perfectly flavored, enhancing the overall taste of your soup.
-
Choose quality broth – A good-quality low-sodium chicken broth provides a solid foundation for your soup. It allows you to control the saltiness while still delivering robust flavor.
-
Toast the baguette slices before adding them – Lightly toasting your baguette slices not only adds texture but also prevents them from becoming too soggy when added to the soup.
How to Serve French Onion Chicken Soup
Serving French Onion Chicken Soup can be as delightful as making it! Here are some ideas to present this warm, comforting dish beautifully.
Garnishes

-
Extra cheese – A sprinkle of additional Gruyère cheese on top just before serving can create an inviting melty layer, enhancing both presentation and taste.
Side Dishes
-
Mixed Greens Salad – A simple salad with mixed greens and a light vinaigrette can provide a refreshing contrast to the hearty soup. The crispness of the greens balances perfectly with the warm, savory soup.
-
Garlic Bread – Crunchy garlic bread makes an excellent accompaniment. Its buttery, garlicky goodness pairs wonderfully with each spoonful of soup, allowing you to soak up every bit!
-
Roasted Vegetables – A platter of seasonal roasted vegetables adds color and nutrients to your meal. The caramelized edges and earthy flavors complement the soup beautifully.
-
Quinoa Salad – A light quinoa salad with diced cucumbers, tomatoes, and a lemon vinaigrette offers a healthy side option that contrasts nicely with the richness of the soup while adding extra protein.
