  • 4 boneless skinless chicken breasts
  • 2 teaspoons olive oil
  • 2 medium yellow onions, thinly sliced
  • 1 tablespoon balsamic vinegar
  • 1 tablespoon Worcestershire sauce
  • Use either ½ teaspoon of dried thyme or 1 teaspoon of fresh thyme leaves.
  • 3 ounces Gruyère cheese, coarsely grated
  • Use ½ cup of all-purpose flour or a gluten-free flour mix if preferred.
  • 1 teaspoon kosher salt
  • Pepper (to taste)
  • ½ teaspoon paprika
  • 2 teaspoons unsalted butter
  • 1/2 cup chicken broth


  • Step 1: Caramelize the Onions

Preheat the olive oil in a large skillet over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until they turn a rich, golden brown. This process should take around 20-25 minutes. If the onions start to stick, deglaze the pan with a splash of water.

  • Step 2: Enhance the Onions’ Flavor

After the onions are caramelized, mix in the balsamic vinegar, Worcestershire sauce, and thyme. Cook for another 2-3 minutes until the liquids have slightly reduced. Transfer the onions from the skillet and set them aside.

  • Step 3: Prepare the Chicken

In a shallow dish, blend the flour, kosher salt, pepper, and paprika. Coat each chicken breast evenly with the flour mixture on both sides.

  • Step 4: Cook the Chicken

Heat the same skillet over medium heat and add the unsalted butter. Allow the butter to melt and begin to sizzle before adding the chicken breasts. Place the chicken in the skillet and cook for 5-6 minutes on each side, ensuring they are golden brown and fully cooked through.

  • Step 5: Make the Sauce

Pour the chicken broth into the skillet, ensuring you scrape up any browned bits from the bottom of the pan. Add the caramelized onions back into the skillet and stir to combine with the broth, creating a rich sauce.

  • Step 6: Assemble and Bake

Preheat your oven to 375°F (190°C). Place the cooked chicken breasts in an oven-safe dish. Pour the onion and broth mixture over the chicken, ensuring they are well covered. Evenly sprinkle the grated Gruyère cheese on top.

  • Step 7: Bake to Perfection

Bake the dish in the preheated oven for about 10-15 minutes, or until the cheese is melted and bubbly.

  • Step 8: Serve and Enjoy

After baking, take the dish out of the oven and allow it to cool for a few minutes.Serve the French Onion Chicken warm, accompanied by your favorite vegetables or a fresh salad.
