French Onion Chicken Bake

French Onion Chicken Bake is a comforting, savory dish featuring tender chicken breasts smothered in caramelized onions, melted cheese, and rich French onion soup flavors. Perfect for an easy weeknight dinner that feels indulgent yet simple.

Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons butter
  • 1 cup French onion soup (canned or homemade)
  • 1 teaspoon garlic powder
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 1/2 cups shredded Gruyère cheese
  • 1 tablespoon olive oil
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. In a large skillet, heat butter and olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until caramelized and golden brown, about 20-25 minutes.
  3. Season the chicken breasts with garlic powder, dried thyme, salt, and black pepper.
  4. Place the seasoned chicken in a baking dish and pour the French onion soup evenly over the chicken.
  5. Top the chicken with the caramelized onions, spreading them evenly.
  6. Sprinkle shredded Gruyère cheese over the top.
  7. Bake in the preheated oven for 25-30 minutes until the chicken is cooked through and the cheese is bubbly and golden.
  8. Garnish with freshly chopped parsley if desired before serving.

Notes

For extra crispness, place the bake under the broiler for 2-3 minutes until the cheese is browned on top. Serve with a side of crusty bread or a fresh green salad.
