This savory French Onion Chicken Bake combines the rich flavors of French onion soup with tender chicken breasts, all baked to perfection. It’s a comforting and satisfying dish that’s perfect for a cozy family dinner.


  • 4 boneless, skinless chicken breasts
  • 2 tablespoons olive oil
  • Salt and pepper to taste
  • 2 large onions, thinly sliced
  • 2 cloves garlic, minced
  • 1 tablespoon butter
  • 1 tablespoon all-purpose flour
  • 1 cup beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried thyme
  • 1 cup shredded Swiss cheese
  • Fresh chopped parsley for garnish (optional)


  1. Preheat your oven to 375°F (190°C). Grease a baking dish with cooking spray or olive oil.
  2. Season the chicken breasts with salt and pepper on both sides.
  3. In a large skillet, heat the olive oil over medium-high heat. Add the chicken breasts and cook until golden brown on both sides, about 3-4 minutes per side. Remove the chicken from the skillet and transfer to the prepared baking dish.
  4. In the same skillet, add the sliced onions and cook until softened and caramelized, about 10-15 minutes. Add the minced garlic and cook for an additional minute.
  5. Add the butter to the skillet and let it melt. Sprinkle the flour over the onions and stir to combine, cooking for 1-2 minutes until the flour is lightly browned.
  6. Gradually pour in the beef broth while stirring constantly to avoid lumps. Add the Worcestershire sauce and dried thyme, and simmer for 2-3 minutes until the sauce thickens slightly.
  7. Pour the onion mixture over the chicken breasts in the baking dish.
  8. Sprinkle the shredded Swiss cheese evenly over the top.
  9. Cover the baking dish with foil and bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the cheese is melted and bubbly.
  10. Remove the foil and broil for an additional 2-3 minutes until the cheese is golden brown.
  11. Garnish with fresh chopped parsley if desired, and serve hot. Enjoy your delicious French Onion Chicken Bake!

Note: You can serve this dish with mashed potatoes, rice, or crusty bread to soak up the flavorful sauce.
