Ingredients

Scale

Chicken

  • 2 boneless, skinless chicken breasts

French Onion Filling

  • 2 large yellow onions, thinly sliced
  • 2 tablespoons butter
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves (or parsley)
  • 1/2 cup shredded Gruyère cheese

Cooking

  • 2 tablespoons olive oil
  • Salt and freshly ground black pepper, to taste

Garnish (optional)

  • Fresh parsley or thyme
  • Cracked black pepper
  • Balsamic glaze (for drizzling)

Instructions

  1. Prepare the onions: Thinly slice the yellow onions and sauté them in butter over medium heat. Stir occasionally until the onions are soft, golden, and caramelized, which takes about 15 minutes. This builds the rich foundation of flavor for the stuffing.
  2. Prep the chicken breasts: While the onions cook, butterfly each chicken breast by slicing horizontally without cutting all the way through, creating a pocket. Season both sides generously with salt and pepper.
  3. Assemble the stuffing: Once the onions are caramelized, stir in minced garlic and fresh thyme. Stuff each chicken breast generously with the onion mixture and shredded Gruyère cheese, carefully closing the pocket to hold the filling.
  4. Cook the stuffed chicken: Heat olive oil in a skillet over medium-high heat. Place the stuffed chicken breasts seam-side down first to seal the filling, then cook for 4-5 minutes on each side until golden brown and cooked through. Optionally, finish in a preheated oven to fully melt the cheese.
  5. Rest and serve: Let the chicken rest for a few minutes after cooking to lock in the juices, ensuring each bite is tender and succulent. Garnish with fresh herbs, cracked black pepper, or a drizzle of balsamic glaze as desired.

Notes

  • Pat dry the chicken breasts before cooking to achieve better browning and prevent steaming.
  • Caramelize onions slowly and patiently for maximum sweetness and depth of flavor.
  • Use toothpicks to secure stuffed chicken breasts if they tend to open during cooking.
  • Do not overcook the chicken; internal temperature should reach 165°F (74°C) for perfect juiciness.
  • Allow the chicken to rest before slicing to keep it moist and prevent cheese from spilling out.
