Creating Apple and Brie Stuffed Chicken is a rewarding experience if you follow these clear steps:

1. Preheat Oven: Start by preheating your oven to 375°F (190°C).

2. Prepare the Chicken: Place the chicken breasts on a clean surface. Use a sharp knife to create a pocket in each chicken breast by making an incision along the side without cutting all the way through.

3. Make the Stuffing: In a bowl, combine the diced apple, Brie cheese, fresh thyme, garlic powder, and a pinch of salt and pepper. Mix well until all ingredients are combined.

4. Stuff the Chicken: Generously fill each chicken breast pocket with the apple and Brie mixture. Secure the openings using cooking twine or toothpicks to keep the filling inside during cooking.

5. Season the Chicken: Drizzle olive oil over the stuffed chicken breasts. Season both sides with garlic powder, salt, and pepper.

6. Add Breadcrumbs (Optional): If desired, sprinkle breadcrumbs over the tops of the chicken breasts for added texture and crunch.

7. Bake: Place the stuffed chicken breasts in a baking dish and bake for 30-40 minutes. The chicken should be cooked through and the internal temperature should read 165°F (75°C).

8. Rest: Once the chicken is done, remove it from the oven and let it rest for 15 minutes. This allows the juices to redistribute, ensuring a moist bite.

9. Slice and Serve: Carefully remove the toothpicks or twine before slicing the chicken to reveal the delightful filling.
