Ingredients

Scale

Chicken

  • 4 boneless, skinless chicken breasts or thighs

Onions & Aromatics

  • 3 large yellow onions, thinly sliced
  • 3 tbsp butter
  • 2 tbsp olive oil
  • 2 garlic cloves, minced
  • 1 tbsp brown sugar
  • 1 tsp fresh or dried thyme

Liquids & Seasonings

  • 1 cup beef broth or stock
  • Salt, to taste
  • Freshly ground black pepper, to taste

Toppings

  • 68 slices Swiss or Gruyere cheese
  • 46 slices baguette or 1/2 cup breadcrumbs (optional, for topping)

Instructions

  1. Caramelize the onions: Thinly slice the yellow onions and cook them gently in a mixture of butter and olive oil over medium-low heat. Stir frequently and cook for 20-30 minutes until the onions soften and develop a rich golden brown color. Add brown sugar and thyme during cooking to enhance sweetness and flavor complexity.
  2. Prepare the chicken: While the onions caramelize, season the chicken breasts or thighs generously with salt and pepper. Heat a skillet over medium-high heat and sear the chicken for 2-3 minutes on each side until browned to lock in juices.
  3. Assemble the bake: Transfer the caramelized onions into a baking dish, spreading them out evenly. Pour beef broth over the onions, then nestle the seared chicken pieces on top. Spoon some more broth over the chicken for moisture and flavor.
  4. Add cheese and bread topping: Layer slices of Swiss or Gruyere cheese generously over the chicken. If desired, add baguette slices or sprinkle breadcrumbs on top for a crispy, toasted finish.
  5. Bake until bubbly and golden: Preheat the oven to 375°F (190°C). Bake the assembled dish for 25-30 minutes until the chicken is thoroughly cooked, the cheese is melted and bubbly, and the top is golden brown. Let rest for a few minutes before serving to allow flavors to settle.

Notes

  • Take your time caramelizing onions to develop deep sweetness and color.
  • Searing chicken before baking locks in juices and adds flavor.
  • Use quality beef or vegetable broth for richer flavor.
  • Don’t skip the cheese for the classic French onion taste and texture.
  • Let the bake rest 5 minutes before serving to redistribute juices.
