How to Make French Onion Chicken Soup

1. Sauté Onions: In a Dutch oven, heat the extra virgin olive oil over medium heat. Add the sweet onions and shallots, along with kosher salt. Sauté for about 30-40 minutes until they transform into a beautiful caramelized golden hue.

2. Thicken the Base: Stir in the all-purpose flour, cooking for an additional 2-3 minutes. This will help create a rich, velvety texture in your soup.

3. Add Aromatics: Pour in the light white wine and sherry vinegar, then add the fresh thyme sprigs and dried bay leaves. Simmer for about 10 minutes to reduce alcohol and integrate the flavors.

4. Simmer the Soup: Carefully pour in the chicken bone broth and add the boneless skinless chicken thighs. Bring it to a boil, then reduce the heat and let it simmer until the chicken is thoroughly cooked (approximately 25-30 minutes).

5. Shred Chicken: Remove the chicken thighs, shred the meat, and return it to the soup. Taste and adjust seasoning as necessary, and don t forget to remove the thyme and bay leaves!

6. Prepare for Broiling: Ladle the soup into oven-proof bowls, place the toasted baguette or sourdough on top, and cover generously with Gruyère cheese. Broil in the oven for 2-3 minutes or until the cheese is melted and bubbly.

Optional: Garnish with additional fresh thyme for a pop of flavor and color.
