Before you embark on your culinary journey, gather the following ingredients:

  • 4 boneless skinless chicken breasts

  • 2 medium yellow onions, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 1 tablespoon Worcestershire sauce
  • ½ teaspoon dried thyme or 1 teaspoon fresh thyme leaves
  • 3 ounces Gruyère cheese, coarsely grated
  • ½ cup all-purpose flour (or gluten-free flour mix*)
  • 1 teaspoon kosher salt
  • Pepper (to taste)
  • ½ teaspoon paprika
  • 2 teaspoons unsalted butter
  • 1/2 cup chicken broth


  1. Prepare Onions:
    • Heat olive oil in a large nonstick skillet over medium heat.
    • Add thinly sliced onions and sprinkle with a pinch of salt.
    • Cook onions, stirring frequently, until they begin to caramelize and turn golden brown around the edges.
    • Reduce heat to medium-low and add balsamic vinegar, Worcestershire sauce, and thyme. Continue cooking until onions are tender and caramelized, adding water as needed to deglaze the skillet. Set aside.
  2. Prepare Chicken:
    • Season chicken breasts with salt and pepper to taste.
    • In a shallow bowl, combine flour, kosher salt, and paprika.
    • Dredge chicken breasts in the seasoned flour mixture, shaking off any excess.
    • Melt butter in a large nonstick skillet over medium heat.
    • Cook chicken breasts for 3-4 minutes on each side, or until golden brown and cooked through. Remove from skillet and set aside.
  3. Assemble and Cook:
    • In the same skillet, combine chicken broth and a tablespoon of the remaining flour mixture, whisking until smooth.
    • Return cooked chicken breasts to the skillet, spooning caramelized onions over the top.
    • Sprinkle grated Gruyère cheese evenly over the chicken and onions.
    • Cover the skillet and cook over low heat for 3-5 minutes, or until the cheese is melted and bubbly.
    • Serve hot, garnished with fresh thyme leaves if desired.


Serving and Storage Tips:

  1. Serving Suggestions:
    • Serve your French Onion Chicken hot and fresh for the best flavor and presentation.
    • Pair it with your favorite side dishes such as mashed potatoes, roasted vegetables, or a crisp green salad for a well-rounded meal.
    • Garnish with fresh thyme leaves or chopped parsley for a pop of color and added flavor.
    • Consider serving alongside a crusty baguette or garlic bread to soak up the savory sauce.
  2. Storage:
    • If you have leftovers, store them in an airtight container in the refrigerator for up to 3-4 days.
    • To reheat, gently warm the chicken in the microwave or oven until heated through. Be cautious not to overcook, as chicken breasts can dry out easily when reheated.
    • For longer storage, you can freeze the cooked chicken in an airtight container or freezer-safe bag for up to 2-3 months. Thaw in the refrigerator overnight before reheating.
    • Keep any leftover caramelized onions separately and use them as a flavorful addition to sandwiches, omelets, or pasta dishes.
  3. Meal Prep:
    • This recipe is excellent for meal prep as you can prepare the caramelized onions and cook the chicken in advance, then assemble and heat just before serving.
    • Divide the cooked chicken and onions into individual meal containers for convenient grab-and-go lunches or dinners throughout the week.
    • Consider doubling the recipe and freezing individual portions for future quick and easy meals.

By following these serving and storage tips, you can enjoy the delicious flavors of French Onion Chicken whenever the craving strikes, whether freshly cooked or reheated from leftovers. Bon appétit!

  2. Herb Infusions:
    • Customize the flavor profile of your French Onion Chicken by incorporating different herbs and spices. Consider adding rosemary, sage, or Italian seasoning for a fragrant and aromatic touch.
  3. Protein Options:
    • Swap out chicken breasts for other protein options such as boneless pork chops, turkey cutlets, or even tofu for a vegetarian alternative. Adjust cooking times accordingly based on the protein you choose.
  4. Gluten-Free Variation:
    • For a gluten-free version of this recipe, use a gluten-free flour mix or almond flour in place of all-purpose flour for dredging the chicken. Ensure all other ingredients used are certified gluten-free.
  5. Vegetarian Twist:
    • Create a vegetarian-friendly version of this dish by omitting the chicken altogether and using thick slices of portobello mushrooms or cauliflower steaks as the base. Follow the same steps for caramelizing onions and melting cheese for a satisfying meatless meal.
  6. Baked Casserole:
    • Transform this recipe into a comforting baked casserole by layering the caramelized onions, chicken, and cheese in a baking dish. Bake in the oven at 375°F (190°C) for 20-25 minutes or until the cheese is golden and bubbly.
  7. Spicy Kick:
    • Add a spicy twist to your French Onion Chicken by incorporating sliced jalapeños or red pepper flakes into the caramelized onions. For an extra kick, drizzle with sriracha sauce or sprinkle with cayenne pepper before serving.
  8. Creamy Sauce:
    • Elevate the dish with a creamy sauce by whisking in a splash of heavy cream or sour cream into the broth mixture before adding it to the skillet. This will create a luscious sauce that complements the savory flavors of the dish.
