Ingredients

Scale

Chicken

  • 4 boneless, skinless chicken breasts
  • 2 tablespoons olive oil
  • Salt and pepper, to taste

Stuffing

  • 3 large yellow onions, peeled and thinly sliced
  • 2 tablespoons butter
  • 3 garlic cloves, minced
  • 1 teaspoon fresh thyme leaves (plus extra for garnish)
  • 3 tablespoons Dijon mustard
  • 1 cup shredded Gruyere or Swiss cheese
  • Salt and pepper, to taste

Instructions

  1. Prepare the Onions: Peel and thinly slice the yellow onions. In a skillet, melt butter over medium heat and add the onions with a pinch of salt. Cook slowly, stirring occasionally, for 25-30 minutes until deep golden brown and caramelized. Stir in minced garlic and fresh thyme, let the aromas develop as garlic softens, then remove from heat.
  2. Prep the Chicken Breasts: While onions cook, butterfly each chicken breast by slicing horizontally through the thickest part without cutting all the way through. Open like a book and gently pound to even thickness for stuffing and even cooking.
  3. Stuff the Chicken: Spread a thin layer of Dijon mustard on one side of each butterflied chicken breast. Add a generous scoop of caramelized onion mixture and top with shredded Gruyere or Swiss cheese. Fold chicken back over to encase filling.
  4. Sear the Chicken: Heat olive oil in a large oven-safe skillet over medium-high heat. Place stuffed chicken breasts seam side down and sear until golden brown, about 3-4 minutes per side, sealing in juices and creating a crust.
  5. Bake Until Juicy: Transfer skillet to a preheated oven at 375°F (190°C) and bake for 15-20 minutes until chicken is cooked through and cheese melts. Let rest a few minutes before slicing to lock in juices.

Notes

  • Slow caramelization develops the natural sweetness of onions.
  • Pounding chicken to even thickness ensures even cooking and juiciness.
  • Press chicken edges firmly after stuffing to keep filling inside while cooking.
  • Use an oven-safe skillet to sear and bake in the same pan for less cleanup and locked-in flavor.
  • Let the chicken rest after baking to keep it tender and juicy.
