Preparing French Onion Chicken Soup
Creating the perfect French Onion Chicken Soup is both a delightful culinary adventure and a heartwarming experience. This richly flavored soup is packed with tender chicken and the sweetness of caramelized onions, making it perfect for a cozy night in. Let’s walk through the steps to achieve that bowl of golden goodness!
Slice the Onions
Everything starts with the onions. You’ll need about 3 pounds of yellow onions, which means peeling, halving, and thinly slicing them. Aim for uniform slices—this helps them caramelize evenly. A sharp knife is your best friend here! Pro tip: If you find slicing onions a tear-inducing task, try chilling them beforehand.
Sauté the Onions to Golden Perfection
In a Dutch oven or a large heavy-bottomed pot, melt 4 tablespoons of unsalted butter over medium heat. Add the sliced onions, dried thyme, bay leaves, 1.5 teaspoons of kosher salt, and black pepper. Now, here's the key: cook these slowly, stirring often for around 35 to 45 minutes, until they transform into a beautiful amber hue. This process is where the magic happens, so don’t rush it! The aroma in your kitchen will be irresistible—just wait until you see the color change.
Add Vegetables and Chicken
Once your onions are perfectly caramelized, it’s time to get colorful! Toss in sliced carrots, chopped celery, and minced garlic. Sauté these veggies for about 5 minutes until they brighten up and become crisp-tender. Meanwhile, season your chicken (breasts or thighs) with the remaining salt. If you’re using large chicken breasts, butterflying them is a great option for even cooking.
Deglaze and Thicken the Soup
Now, let's create layers of flavor. Pour in the chicken broth and a splash of your favorite non-alcoholic cooking sherry—this adds a lovely depth without the alcohol. To thicken the soup, sprinkle in some flour while stirring to ensure it mixes smoothly. This step is crucial; it gives your soup that satisfying, hearty texture.
Simmer to Develop Rich Flavors
Bring everything to a lively simmer! Lower the heat to maintain a gentle simmer, and let it cook until the chicken is tender—about 10 to 20 minutes depending on your chicken cut. The longer it simmers, the richer and deeper the flavors become. This is a perfect moment to set a timer and kick back while it bubbles away.
Prepare the Cheesy Toasts
No French Onion Chicken Soup would be complete without cheesy toasts! Slice a baguette into thick pieces, then generously top them with grated Gruyère cheese. Broil them for a couple of minutes until they are golden and bubbly. Trust us—this is the crowning glory of your dish.

Variations on French Onion Chicken Soup
Add Herbs for Extra Flavor
Elevate your French Onion Chicken Soup by adding fresh herbs! A handful of fresh rosemary or parsley can add a burst of freshness that beautifully complements the caramelized onions. Alternatively, try experimenting with a mix of dried herbs—oregano and marjoram work wonderfully to deepen the flavor profile. Don’t forget to taste as you go; the right herb blend can transform your soup!
Spice it Up with a Kick
For those who crave a fiery kick, consider adding a dash of red pepper flakes or even a splash of sriracha. Not only does this add heat, but it also brings a nice contrast to the rich, savory flavors of the soup. Another fun variation is to stir in some cumin for a warm, earthy undertone. So, how adventurous are you feeling today?

Cooking Tips and Notes for French Onion Chicken Soup
Best Onion Options
When crafting your French Onion Chicken Soup, opt for yellow onions for their perfect balance of sweetness and depth. You could also try Vidalia onions for a sweeter touch or shallots for a more delicate flavor. Whichever you choose, ensure they're fresh for the best taste!
Important Cooking Techniques for Perfect Texture
Achieving that rich, caramelized flavor is all about patience. Cook the onions slowly over medium heat, stirring regularly to prevent burning. This develops their natural sugars, which forms the base of the soup's flavor. For optimal chicken texture, don’t overcrowd the pot—this ensures even cooking. Finally, consider adding a splash of apple cider vinegar or lemon juice after cooking for added brightness. Don't forget to shred the chicken into bite-sized pieces for a comforting finish!

French Onion Chicken Soup
Equipment
- Dutch Oven
- Box grater
- rimmed baking sheet
Ingredients
For the soup
- 3 pounds yellow onions about 4 large or 6 medium
- 6 tablespoons unsalted butter divided
- 1 teaspoon dried thyme
- 2 dried bay leaves
- 2.5 teaspoons kosher salt divided, plus more as needed
- 0.5 teaspoon freshly ground black pepper
- 3 medium carrots
- 3 medium stalks celery
- 3 cloves garlic
- 2 pounds boneless, skinless chicken breasts or thighs
- 0.75 cup dry white wine
- 1 tablespoon dry sherry
- 0.25 cup all-purpose flour
- 6 cups low-sodium chicken broth
For the cheesy toasts (optional)
- 2 ounces Gruyère cheese about heaping ½ cup
Instructions
Make the soup
- Peel, halve, and thinly slice 3 pounds yellow onions (about 10 cups).
- Melt 4 tablespoons of the unsalted butter in a Dutch oven or large heavy-bottomed pot over medium heat. Add the onions, 1 teaspoon dried thyme, 2 dried bay leaves, 1 ½ teaspoons of the kosher salt, and ½ teaspoon black pepper. Cook, stirring often and scraping the bottom of the pot with a wooden spoon to prevent burning, until the onions are soft and amber brown, 35 to 45 minutes.
- Meanwhile, prepare the following, adding each to the same medium bowl as you complete it: Peel and cut 3 medium carrots crosswise into ¼-inch-thick rounds (about 1 ¼ cups). Cut 3 medium celery stalks crosswise into ¼-inch-thick pieces (about 1 cup). Mince 3 garlic cloves.
- Add the remaining 2 tablespoons unsalted butter to the onion mixture. When the butter is melted, add the carrot mixture and cook, stirring occasionally, until the carrots are crisp-tender and brightened in color, about 5 minutes. Meanwhile, season 2 pounds boneless, skinless chicken breasts or thighs all over with the remaining 1 teaspoon of the kosher salt. (If using thick chicken breasts, start at the thickest end and hold your knife parallel to the cutting board, then cut the chicken breasts in half — also known as butterflying.)
- Pour ¾ cup dry white wine and 1 tablespoon dry sherry into the Dutch oven. Cook, stirring occasionally, until mostly evaporated, 2 to 3 minutes. Sprinkle with ¼ cup all-purpose flour and cook, stirring constantly, for 1 minute to cook the floury taste out.
- While stirring constantly, pour in 6 cups low-sodium chicken broth. Add the chicken in a single layer. Increase the heat to medium-high and bring to a lively simmer.
- Reduce the heat as needed to maintain a gentle simmer. Cook, stirring and scraping the bottom of the pot occasionally, until the chicken is cooked through and an instant-read thermometer inserted into the thickest part of the chicken registers at least 165°F, about 10 minutes for thighs or 12 to 20 minutes for breasts. Meanwhile, prep the cheesy toasts if desired.
Make the cheesy toasts
- Arrange an oven rack 3 to 4 inches below the broiler unit and set the oven to broil. Cut ½ baguette crosswise on a bias into 1-inch-thick slices (about 8). Place in a single layer on a rimmed baking sheet. Grate 2 ounces Gruyère cheese on the largest holes of a box grater (about heaping ½ cup). Sprinkle the bread evenly with the cheese.
- Using tongs, transfer the chicken to a clean cutting board. Use two forks to shred the chicken into bite-sized pieces. Return the chicken to the pot. Remove and discard the bay leaves. Taste and season the soup with more kosher salt as needed.
- Broil the bread until the cheese is melted and bubbling, 30 seconds to 1 minute. Top each bowl of soup with a piece of cheese toast.
