Create a comforting, flavorful dinner inspired by French Onion Soup using this easy one-pot method. This recipe features juicy chicken breasts simmered with caramelized onions and topped with melted Gruyère cheese for minimal cleanup.

Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon salt, divided
  • 1/2 teaspoon black pepper, divided
  • 2 cloves garlic, minced
  • 1 tablespoon all-purpose flour
  • 2 cups beef broth
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • 1/4 cup dry sherry or white wine (optional)
  • 1 cup shredded Gruyère cheese
  • 1/4 cup shredded Swiss cheese

Instructions

  1. Season the chicken breasts on both sides with 1/2 teaspoon salt and 1/4 teaspoon pepper.
  2. Heat the olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for 15 to 20 minutes until they are deeply caramelized and soft. Remove the onions from the skillet and set them aside.
  3. Season the skillet with the remaining salt and pepper. Place the chicken breasts in the hot skillet and sear for 3 to 4 minutes per side until lightly browned. Remove the chicken and set it aside with the onions.
  4. Add the minced garlic to the skillet and cook for 30 seconds until fragrant. Sprinkle the flour over the garlic and cook for 1 minute, stirring constantly to create a roux.
  5. Slowly whisk in the beef broth, Worcestershire sauce, and dried thyme. If using, pour in the sherry or wine. Bring the mixture to a simmer and cook until the sauce thickens slightly, about 3 minutes.
  6. Return the seared chicken breasts to the skillet. Spoon the caramelized onions over the top of the chicken.
  7. Transfer the skillet to a preheated oven at 400 degrees Fahrenheit (200 degrees Celsius). Bake for 15 minutes.
  8. Remove the skillet from the oven. Sprinkle the Gruyère and Swiss cheese evenly over the chicken and onions. Return to the oven and bake for another 5 to 7 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
  9. Let the chicken rest for 5 minutes before serving directly from the skillet. Serve this easy chicken dinner with mashed potatoes or crusty bread to soak up the savory sauce.

Notes

  • For the deepest onion flavor, do not rush the caramelization process; low and slow heat is key.
  • If you do not have an oven-safe skillet, transfer the sauce and onions to a baking dish before adding the chicken and cheese.
  • Use high-quality beef broth for the best savory base flavor.
