Preheat your oven to 400°F (200°C).
In a bowl, mix balsamic vinegar, honey, minced garlic, olive oil, salt, and pepper.
Place the chicken breasts in a baking dish.
Pour the balsamic mixture over the chicken, ensuring they are well coated.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through.
Baste the chicken with the sauce halfway through cooking for added flavor.
If using, add chopped vegetables around the chicken in the last 10 minutes of baking.
Once cooked, remove the chicken from the oven and let it rest for a few minutes.
Drizzle additional balsamic glaze over the chicken before serving.
Garnish with fresh thyme and serve warm.
