Follow these easy steps to create delicious Italian Basil Chicken that will tantalize your taste buds:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Marinade: In a bowl, whisk together olive oil, balsamic vinegar, minced garlic, salt, pepper, and red pepper flakes.
3. Marinate the Chicken: Place the chicken breasts in a large resealable bag or a shallow dish. Pour the marinade over the chicken, ensuring it is well coated. Marinate for at least 15 minutes (or up to 2 hours in the refrigerator for extra flavor).
4. Sear the Chicken: In a large oven-safe skillet, heat a drizzle of olive oil over medium-high heat. Remove the chicken from the marinade (discard the marinade) and sear the chicken for 4-5 minutes on each side until golden brown.
5. Add Tomatoes and Basil: Add the halved cherry tomatoes and chopped basil around the chicken in the skillet.
6. Bake: Transfer the skillet to the preheated oven. Bake for 15-20 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
7. Add Cheese: During the last 5 minutes of baking, sprinkle grated Parmesan cheese over the chicken and tomatoes for an extra layer of flavor.
8. Rest the Chicken: Once done, remove the skillet from the oven and let the chicken rest for 5 minutes before serving.
