Cooking method
- Start by peeling, halving, and thinly slicing the onions.
- In a Dutch oven or large heavy pot, melt 4 tablespoons of butter over medium heat.
- Add the sliced onions, thyme, bay leaves, 1 1/2 teaspoons of salt, and black pepper. Stir frequently, scraping the bottom to prevent sticking, until the onions turn soft and amber brown, about 35 to 45 minutes.
- While the onions are cooking, prepare the carrots, celery, and garlic. Slice and mince them, adding each to a medium bowl.
- Add the remaining 2 tablespoons of butter to the onion mixture. Mix in the prepared carrots, celery, and garlic, cooking until the veggies are crisp-tender and vibrant, around 5 minutes.
- Season the chicken with the remaining 1 teaspoon of salt. Butterfly thick breasts for even cooking.
- Pour the white wine and dry sherry into the pot. Allow it to cook for 2 to 3 minutes, stirring occasionally until mostly evaporated.
- Sprinkle flour over the mixture and stir constantly for about 1 minute to remove the raw flour taste.
- Gradually stir in the chicken broth, then add the chicken in a single layer. Bring to a lively simmer over medium-high heat.
- Once simmering, reduce heat and maintain a gentle simmer. Cook until the chicken reaches an internal temperature of 165°F—about 10 minutes for thighs or 12 to 20 minutes for breasts.
- If you want to top the soup with cheesy toast, arrange the oven rack 3 to 4 inches below the broiler. Broil the baguette slices topped with Gruyère cheese until melted and bubbly, roughly 30 seconds to 1 minute.
- Transfer the chicken to a cutting board, shred it with forks, and return it to the pot. Remove the bay leaves, taste, and adjust the seasoning as needed.
- Ladle the soup into bowls, topping each with a cheesy toast slice, if desired. Enjoy hot for a comforting meal!

For a cozy evening, simply accompany it with a cheesy garlic bread.
Storage and reheating tips
Make sure to cool the soup to room temperature before transferring it to an airtight container. It will keep well in the refrigerator for up to 3 days. To freeze, store it in freezer-safe containers or bags, and it can last for up to 3 months. When reheating, ensure it’s warmed through to 165°F, and if the soup thickens too much, consider adding a splash of water or broth.
Helpful cooking tips
- Patience is key when caramelizing onions; take your time to develop their flavor fully.
- Shredding chicken after cooking offers a softer texture, ensuring each spoonful is tender.
- Adjust seasonings at the end; this enhances flavors as the soup cools slightly and lets you get it just right.
Creative twists
Feel free to experiment with this soup! You could add different herbs like rosemary or use a splash of balsamic vinegar for a tangy kick. For a spicy edge, incorporate some red pepper flakes or a jalapeño. If you’re looking for a vegan version, swap out the chicken with mushrooms and use vegetable broth instead.
