Preheat your oven to 375°F (190°C).
Prepare the chicken breasts by placing them between two sheets of plastic wrap. Gently pound them to an even thickness, about 1/2 inch thick.
Season both sides of the chicken breasts with salt, black pepper, garlic powder, and dried thyme.
Take a slice of Brie cheese and place it on one side of each chicken breast. Top the cheese with a spoonful of cranberry sauce.
Fold the chicken breasts over, encasing the Brie and cranberry sauce, and secure them with toothpicks if necessary.
In an oven-safe skillet, heat olive oil and butter over medium heat. Once hot, carefully add the stuffed chicken breasts, cooking for about 4-5 minutes on each side until golden brown.
Once browned, remove the skillet from the heat. Pour in the chicken broth, balsamic vinegar, and honey. Spoon some of the liquid over the chicken.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Remove the skillet from the oven, and let the chicken rest for 5 minutes before serving. Garnish with fresh parsley.
