This rich and savory French Onion Chicken features crispy-skinned, pan-seared thighs nestled in a bed of deeply caramelized onions, topped with melty Gruyere cheese. A comforting and elegant one-pan meal inspired by the classic soup.

  • Total Time: 1 hour 15 minutes
  • Yield: 6 servings

Ingredients

  • 6 medium chicken thighs, skin-on, bone-in
  • Salt and pepper, to taste
  • 1 teaspoon onion powder
  • 2 tablespoons butter
  • 1 large onion (or 1 medium), thinly sliced
  • 1/2 cup chicken broth
  • 1 teaspoon fresh thyme leaves
  • 8 ounces Gruyere cheese, shredded

Instructions

  1. Pat the chicken thighs dry and season both sides with salt, pepper, and onion powder.
  2. In a large oven-safe skillet, melt butter over medium heat.
  3. Once hot, add chicken thighs skin-side down. Sear for 4–5 minutes until golden, flip, and cook another 4 minutes. Remove from skillet and set aside.
  4. Add sliced onions to the same pan. Season lightly with salt and pepper. Reduce heat to medium-low and cook slowly, stirring frequently, until deeply golden and caramelized (about 20 minutes).
  5. Preheat oven to 375°F (190°C) during the final 10 minutes of caramelizing.
  6. Stir in thyme and cook for 1 minute. Add chicken broth and simmer until reduced by half (about 2 minutes).
  7. Return chicken to the pan and sprinkle with shredded Gruyere cheese.
  8. Bake uncovered for 20 minutes, until cheese is melted and bubbly and chicken is cooked through.

Notes

  • Use yellow or sweet onions for deeper caramelized flavor.
  • Gruyere can be substituted with Swiss or provolone in a pinch.
  • For crispier skin, broil for the last 2 minutes.
  • Serve with crusty bread or mashed potatoes to soak up the sauce.
