French Onion Chicken is a comforting, flavorful dish that combines tender chicken breasts with caramelized onions, melted cheese, and a savory broth-based sauce. Inspired by classic French onion soup, this skillet meal is rich, elegant, and perfect for both weeknight dinners and special occasions.

Ingredients

  • 4 boneless, skinless chicken breasts
  • 3 large onions, thinly sliced (yellow or sweet)
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 2 cloves garlic, minced
  • 1 1/2 cups beef broth (or chicken broth)
  • 1 tbsp Worcestershire sauce
  • 1/2 tsp dried thyme
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1/4 cup all-purpose flour (for dredging)
  • 1 cup shredded Gruyère or Swiss cheese (mozzarella optional)
  • 1 tbsp chopped fresh parsley (for garnish)

Instructions

  1. Season chicken breasts with salt and pepper, then lightly dredge them in flour, shaking off any excess.
  2. In a large skillet, heat olive oil and butter over medium heat. Sear chicken for 4–5 minutes per side until golden brown. Remove and set aside.
  3. In the same skillet, add sliced onions and cook over medium-low heat for 20–25 minutes, stirring frequently until caramelized and golden brown. Add more butter if needed.
  4. Stir in minced garlic and cook for 30 seconds.
  5. Pour in beef broth and Worcestershire sauce, scraping up browned bits. Add dried thyme and bring to a gentle simmer.
  6. Return the chicken to the skillet and spoon the onion mixture over it. Cover and simmer for 10–15 minutes, until the chicken is cooked through.
  7. Sprinkle shredded Gruyère or Swiss cheese over each chicken breast, cover again, and cook until the cheese melts completely.
  8. Garnish with chopped parsley and serve hot with mashed potatoes, rice, or noodles.

Notes

  • Use Gruyère for the best authentic flavor, but Swiss or provolone are great substitutes.
  • Add mushrooms for a deeper, umami twist.
  • Deglaze the pan with white wine for extra richness.
  • For a creamy variation, stir in ¼ cup heavy cream before adding cheese.
  • To make it gluten-free, use gluten-free flour for dredging.
