You create this rich, savory French Onion Chicken Bake in one skillet. It combines tender chicken breasts with deeply caramelized onions and a topping of melted Gruyère cheese for a satisfying, comforting weeknight dinner.

Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup low-sodium beef broth
  • 1 tablespoon Worcestershire sauce
  • 1/2 cup shredded Gruyère cheese
  • 1/4 cup shredded Provolone cheese
  • 2 tablespoons French fried onions (optional, for topping)

Instructions

  1. Season the chicken breasts on both sides with salt and pepper.
  2. Heat the olive oil in a large, oven-safe skillet over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for 15 to 20 minutes until they are deeply caramelized and sweet.
  3. Stir in the dried thyme to the onions and cook for 1 minute until fragrant.
  4. Push the onions to one side of the skillet. Place the seasoned chicken breasts in the empty side of the skillet. Sear the chicken for 3 to 4 minutes per side until lightly browned.
  5. Pour the beef broth and Worcestershire sauce around the chicken in the skillet. Bring the liquid to a simmer.
  6. Transfer the entire skillet to a preheated oven at 400 degrees Fahrenheit. Bake for 15 to 20 minutes, or until the chicken reaches an internal temperature of 165 degrees Fahrenheit.
  7. Remove the skillet from the oven. Sprinkle the Gruyère and Provolone cheese evenly over the chicken breasts. If using, sprinkle the French fried onions over the cheese.
  8. Return the skillet to the oven for 3 to 5 minutes, or until the cheese is fully melted and bubbly.
  9. Let the French Onion Chicken rest in the skillet for 5 minutes before serving directly from the pan.

Notes

  • For an even richer flavor, use dry sherry or white wine instead of a portion of the beef broth during the simmering step.
  • If you do not have an oven-safe skillet, transfer the seared chicken and onion mixture to a baking dish before adding the broth and baking.
  • Serve this hearty chicken dinner over egg noodles or mashed potatoes to soak up the savory pan juices.
