  • 4 boneless, skinless chicken breasts
  • 2 large onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • Salt and black pepper, to taste
  • 1 cup beef or chicken broth
  • 1 cup shredded Gruyère or Swiss cheese
  • ½ cup grated Parmesan cheese
  • Fresh thyme leaves, for garnish (optional)


1. Sautéing the Onions:

  • Preheat your oven to 375°F (190°C).
  • In a large skillet, melt the butter and heat the olive oil over medium heat.
  • Add the sliced onions and cook, stirring occasionally, until they caramelize and turn a deep golden brown, about 20-25 minutes.
  • Stir in the minced garlic and dried thyme, cooking for an additional 1-2 minutes. Set aside.

2. Preparing the Chicken:

  • Season the chicken breasts with salt and black pepper on both sides.
  • In the same skillet, sear the chicken breasts over medium-high heat until they are golden brown on both sides, about 3-4 minutes per side. They don’t need to be fully cooked at this stage. Remove from the skillet and set aside.

3. Assembling the Dish:

  • In a baking dish, spread half of the caramelized onion mixture evenly across the bottom.
  • Place the seared chicken breasts on top of the onions.
  • Spoon the remaining caramelized onions over the chicken breasts.

4. Adding the Broth and Cheese:

  • Pour the beef or chicken broth into the baking dish around the chicken.
  • Sprinkle the shredded Gruyère or Swiss cheese over the chicken breasts and onions.
  • Follow with the grated Parmesan cheese for an extra layer of flavor.

5. Baking and Finishing:

  • Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the chicken is fully cooked (internal temperature of 165°F or 74°C).

6. Garnishing and Serving:

  • Once cooked, remove the dish from the oven and let it rest for a few minutes.
  • Garnish with fresh thyme leaves, if desired, before serving.
  • Serve the French Onion Chicken Bake directly from the baking dish, allowing everyone to enjoy the flavorful combination of tender chicken, caramelized onions, and melted cheese.
