Creating One Pan Balsamic Chicken is simple when you follow these easy steps:

1. Prepare the Marinade: In a small bowl, mix balsamic vinegar, olive oil, minced garlic, oregano, thyme, salt, and pepper.
2. Marinate the Chicken: Place chicken breasts in a shallow dish and pour the marinade over them. Let them marinate for at least 15 minutes (or up to a few hours if you have time).
3. Preheat the Oven: Preheat your oven to 400°F (200°C).
4. Sear the Chicken: In a large, oven-safe skillet, heat a drizzle of olive oil over medium-high heat. Add marinated chicken and sear for about 4-5 minutes on each side until golden brown.
5. Add Vegetables: Scatter the cherry tomatoes and broccoli (or green beans) around the chicken in the skillet.
6. Pour Remaining Marinade: Drizzle the remaining marinade over the chicken and vegetables.
7. Bake: Transfer the skillet to the oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the vegetables are tender.
8. Garnish: Remove from the oven and let rest for a few minutes. Garnish with fresh basil, if desired.
9. Serve: Slice the chicken, serve it alongside the cooked vegetables, and drizzle some of the pan sauce over the top.

Following these steps will help you create a dish that is not only visually appealing but also bursting with flavor.
