Ingredients

Scale

Chicken

  • 4 boneless, skinless chicken breasts

Caramelized Onions

  • 3 large yellow onions, thinly sliced
  • 2 tbsp butter
  • 1 tbsp olive oil, plus extra for searing
  • 2 cloves garlic, minced
  • 1 tbsp balsamic vinegar (optional)

Cheese

  • 3/4 cup shredded mozzarella or Gruyere cheese

Seasoning and Herbs

  • 1 tsp fresh thyme leaves
  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Prepare the caramelized onions: Slice the yellow onions thinly and cook them slowly in butter and olive oil over medium-low heat until golden brown and sweet, stirring occasionally to avoid burning. Toward the end, add minced garlic and a splash of balsamic vinegar to deepen the flavor. Remove from heat once caramelized.
  2. Prep the chicken breasts: Using a sharp knife, carefully slice a pocket into each chicken breast without cutting all the way through; this pocket will hold the stuffing.
  3. Stuff and season the chicken: Fill each chicken pocket generously with the caramelized onions and sprinkle with your choice of cheese. Season the outside of each breast with salt, black pepper, and fresh thyme.
  4. Sear the chicken: Heat a drizzle of olive oil in a skillet over medium-high heat. Sear the stuffed chicken breasts for 2-3 minutes per side until golden brown to seal in juices and add texture.
  5. Bake until cooked through: Transfer the seared chicken breasts to a baking dish. Bake in a preheated oven at 375°F (190°C) for about 20 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and bubbly.

Notes

  • Caramelize onions slowly to develop rich, sweet flavor; rushing this step reduces depth.
  • Don’t overstuff chicken pockets to prevent stuffing leakage and ensure even cooking.
  • Use a meat thermometer to confirm chicken is cooked safely to 165°F (74°C).
  • Sear chicken before baking to lock in moisture and create a flavorful crust.
  • Let the chicken rest for 5 minutes after baking to keep it juicy.
