Ingredients

  • 4 tablespoon Salted Butter
  • 2 tablespoon Olive Oil
  • 4 Yellow Onion Thinly Sliced
  • 1 tablespoon Minced Garlic
  • ¾ Cup Dry White Wine
  • 3 Sprigs Fresh Thyme
  • 3 Cups Rotisserie Chicken Shredded
  • 3 Cups Chicken Stock
  • 3 Cups Beef Stock
  • 2 Bay Leaves
  • Crostini For Serving
  • 8 Oz Gruyére Cheese Shredded

Instructions

  • Preheat the oven to 450°f and slice the Baguette into one-inch crostinis.
  • Spread them evenly onto a parchment-paper-lined baking sheet and spray them with cooking spray. Flip them over, spray the other side, and then salt the top with Kosher salt.
  • Bake the crostinis for 10-15 minutes, watching them in the last few minutes to prevent overcooking.
  • Remove them from the oven and set aside until ready to serve.
  • Slice all of the onions and set them aside.
  • Add olive oil and butter to a Dutch oven or stewpan over medium-low heat.
  • Once the butter is fully melted, add the onions, stirring to thoroughly coat them in the oil and butter mixture.
  • Occasionally, stir the onions as they begin to caramelize, salt them with kosher salt, and then allow them to continue caramelizing.
  • Once the onions have been lightly caramelized, add the garlic, stir to incorporate, pour in the wine, deglaze the pot, and allow the wine to simmer for about 6 minutes.
  • Sprinkle in the chopped fresh thyme and give it all a good stir.
  • Add the shredded chicken to the onions, stirring to ensure even distribution.
  • Pour in the Beef Stock and Chicken Stock. Stir the French Onion Chicken Soup, add the bay leaves, bring to a boil, and then reduce the heat to low, simmering, uncovered, for 20 minutes. 
  • While the soup simmers, shred your cheese and set aside until ready to serve.
  • Ladle the soup into the bowls of your choice, and top each bowl with your preferred amount of cheese, followed by a few crostinis. 
  • Serve Hot, and Enjoy!

Notes

  • Caramelize the onions slowly – This step is key to achieving the deep, sweet flavor of an authentic French Onion Soup with Chicken.
  • Use quality stock – A mix of chicken stock and beef stock creates the best depth of flavor.
  • Choose the right cheese – Gruyère cheese is traditional, but Swiss or Provolone works in a pinch.
  • Make it ahead – The flavors develop even more if made a day in advance.
