Description

Comforting french onion chicken soup blends classic French flavors with hearty chicken in a rich, savory broth. Caramelized onions and melted cheese create a luxurious depth that brings warmth to your dining experience.


Ingredients

Scale

Main Ingredients:

  • 4 large yellow onions, thinly sliced
  • 2 cups cooked chicken, shredded or diced
  • 6 cups chicken broth

Cooking Fats and Liquid:

  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • ¼ cup dry white wine (optional)

Aromatics and Seasonings:

  • 3 garlic cloves, minced
  • 2 sprigs of thyme (or ½ teaspoon dried thyme)
  • 1 bay leaf
  • 2 teaspoons sugar (optional, for caramelizing the onions)
  • Salt and pepper, to taste

Topping:

  • 4 slices of crusty bread or baguette
  • 1 cup shredded Gruyere or Swiss cheese

Instructions

  1. Create a flavor foundation by gently melting butter and olive oil together in a spacious pot or Dutch oven over medium-low heat, ensuring even temperature distribution.
  2. Carefully layer sliced onions into the warm fat, stirring periodically to promote uniform caramelization and prevent burning during the 35-40 minute transformation process.
  3. As onions gradually turn a rich golden-amber color, optionally sprinkle a pinch of sugar to intensify their natural sweetness and enhance browning.
  4. Introduce minced garlic to the caramelized onions, allowing its aromatic essence to bloom for approximately 60 seconds.
  5. Pour white wine into the pot, using its acidic properties to deglaze and lift the concentrated flavor compounds stuck to the bottom of the cooking vessel.
  6. Incorporate chicken broth, thyme, and bay leaf, creating a robust liquid base that will infuse the soup with deep, layered flavors.
  7. Nestle seasoned chicken pieces directly into the simmering liquid, allowing them to poach gently and absorb the surrounding aromatics.
  8. Allow the soup to simmer uncovered, periodically checking chicken’s doneness and ensuring liquid remains at a gentle, consistent temperature.
  9. Once chicken is perfectly cooked, carefully remove and slice into bite-sized portions, then return to the soup.
  10. Finish by topping with toasted bread and melted Gruyère cheese, creating a luxurious golden crust that adds textural complexity to the dish.

Notes

  • Caramelize onions slowly on low heat for maximum flavor depth, allowing natural sugars to develop rich, sweet undertones without burning.
  • Add a splash of cognac or brandy instead of white wine for an extra layer of complexity and traditional French cooking authenticity.
  • Swap chicken for vegetarian options like portobello mushrooms or plant-based chicken alternatives to create dietary-friendly versions of this classic comfort dish.
  • Use low-sodium chicken broth to control salt levels, enabling home cooks to adjust seasoning precisely according to personal taste preferences.
