  • Total Time: 1 hour
  • Yield: 4 servings

Ingredients

Chicken

  • 2 pounds boneless skinless chicken breast, split in half lengthwise
  • 2 tablespoons olive oil, plus more as needed
  • 1 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper, plus more to taste

Onion Sauce

  • 3-4 large yellow onions, sliced 1/4 inch thick
  • 4 cloves garlic, finely minced
  • 1 tablespoon arrowroot starch
  • 1 cup low-sodium chicken broth
  • 1/2 tablespoon fresh thyme
  • Additional salt and black pepper, to taste

Topping

  • 8 oz Gruyere cheese, shredded
  • Fresh thyme, for garnish

Instructions

  1. Preheat and Heat Oil: Heat a large oven-safe braising pan with a lid over medium-high heat. Once hot, add 2 tablespoons of olive oil to the pan.
  2. Season and Sear Chicken: Liberally season both sides of the chicken breasts with salt and pepper. Add the chicken to the hot skillet and cook for 4-5 minutes on each side until golden and cooked through. Remove the chicken from the pan and set aside.
  3. Caramelize Onions: Reduce the heat to medium-low. Add the sliced onions to the pan and stir to coat in the oil. Cover the pan with the lid and let the onions cook for 20-30 minutes, stirring every 5 minutes, until they become soft and golden brown.
  4. Add Garlic and Arrowroot: Once onions are caramelized, add the minced garlic and cook for 1 minute until fragrant. Sprinkle the arrowroot starch over the onions and stir well to combine.
  5. Make Sauce: Pour in the chicken broth, add fresh thyme, salt, and pepper. Stir until well combined. Increase the heat and bring the mixture to a simmer. Let it simmer uncovered for 3-5 minutes until the sauce slightly thickens. Remove from heat.
  6. Combine Chicken and Sauce: Return the cooked chicken breasts to the pan, spoon the onions and sauce generously over each piece.
  7. Add Cheese and Broil: Top each chicken breast with a generous amount of shredded Gruyere cheese. Place the pan under the broiler until the cheese melts and is bubbly, about 2-3 minutes. Watch carefully to prevent burning.
  8. Garnish and Serve: Remove from the broiler, garnish with fresh thyme sprigs, and serve immediately.

Notes

  • Use an oven-safe braising pan or cast iron skillet to allow for stovetop cooking and broiling.
  • Slice onions uniformly to ensure even caramelization.
  • Arrowroot starch can be substituted with cornstarch if unavailable.
  • Adjust seasoning to taste after the sauce simmers.
  • Keep a close eye while broiling the cheese, as it melts quickly and can burn.
  • Leftover chicken can be refrigerated and reheated gently to preserve moisture.
