French Onion Chicken Bake

This French Onion Chicken Bake combines tender chicken breasts with rich caramelized onions and melted cheese for a comforting, savory meal perfect for weeknight dinners.

Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 3 large yellow onions, thinly sliced
  • 3 tablespoons butter
  • 1 teaspoon olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1 cup beef broth
  • 1 teaspoon Worcestershire sauce
  • 1 cup shredded Gruyère cheese
  • Salt and pepper, to taste
  • 2 tablespoons all-purpose flour

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a large skillet, heat butter and olive oil over medium heat. Add sliced onions and cook, stirring occasionally, until caramelized, about 25-30 minutes.
  3. Add garlic, thyme, and flour to the onions and cook for another 2 minutes.
  4. Pour in beef broth and Worcestershire sauce, stirring to combine, and simmer until slightly thickened, about 5 minutes.
  5. Season chicken breasts with salt and pepper, then place them in a baking dish.
  6. Pour the onion mixture evenly over the chicken breasts.
  7. Sprinkle shredded Gruyère cheese on top.
  8. Bake in preheated oven for 25-30 minutes, or until the chicken is cooked through and cheese is golden and bubbly.
  9. Remove from oven and let rest for 5 minutes before serving.

Notes

For extra richness, serve with a side of creamy mashed potatoes or crusty French bread to soak up the delicious sauce.
