Creating Peach Chicken with Balsamic is straightforward when you follow these simple steps:

1. Marinate the Chicken: In a large bowl, combine the balsamic vinegar, honey, olive oil, minced garlic, salt, black pepper, thyme, and red pepper flakes (if using). Add the chicken breasts and ensure they are well coated. Cover and marinate in the refrigerator for at least 30 minutes, or up to 2 hours for more flavor.

2. Preheat the Oven: Preheat your oven to 400°F (200°C).

3. Prepare the Pan: Remove the chicken from the marinade, reserving the marinade for later. Heat a large oven-safe skillet over medium-high heat and add a splash of olive oil.

4. Sear the Chicken: Once the skillet is hot, add the chicken breasts. Sear them for about 3-4 minutes on each side until browned.

5. Add the Peaches: Once the chicken is seared, add the sliced peaches to the skillet around the chicken.

6. Pour the Marinade: Pour the reserved marinade over the chicken and peaches in the skillet.

7. Bake the Dish: Transfer the skillet to the preheated oven and bake for 15-20 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).

8. Baste the Chicken: Halfway through cooking, spoon some of the sauce over the chicken to keep it moist and flavorful.

9. Serve: Once cooked, remove the skillet from the oven and let it rest for a few minutes. Garnish with fresh basil leaves before serving.
