Creating Cranberry Brie Stuffed Chicken is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prep Chicken: Place each chicken breast between two sheets of plastic wrap. Pound them to about 1/2 inch thick with a meat mallet.
3. Season Chicken: Sprinkle both sides of the chicken breasts with salt and pepper.
4. Stuff Chicken: On each chicken breast, place a few pieces of Brie cheese and a generous spoonful of cranberry sauce. Sprinkle some fresh thyme on top.
5. Fold and Secure: Fold the chicken breasts over the stuffing and secure them with toothpicks or kitchen twine.
6. Sear Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Add the stuffed chicken and sear for about 4-5 minutes on each side until golden brown.
7. Add Broth: Carefully pour the chicken broth and balsamic vinegar (if using) into the skillet around the chicken.
8. Bake: Transfer the skillet to the preheated oven and bake for 25-30 minutes until the chicken is cooked through (internal temperature should reach 165°F or 75°C).
9. Rest Chicken: Remove the skillet from the oven and let the chicken rest for about 10 minutes.
10. Serve: Remove toothpicks or twine before serving. Garnish with fresh parsley if desired.
