Follow these steps to create your Balsamic Glazed Chicken:

1. Prepare Marinade: In a bowl, whisk together balsamic vinegar, honey, minced garlic, olive oil, rosemary, salt, and pepper.
2. Marinate Chicken: Place chicken breasts in a zip-top bag and pour half of the marinade over them. Seal the bag and refrigerate for at least 15 minutes, or up to 2 hours for deeper flavor.
3. Preheat Oven: While chicken is marinating, preheat your oven to 375°F (190°C).
4. Sear Chicken: In a large, oven-safe skillet over medium heat, add a drizzle of olive oil. Once hot, add the marinated chicken breasts and sear for 3-4 minutes on each side until golden brown.
5. Add Remaining Marinade: Pour the remaining marinade over the chicken in the skillet.
6. Bake: Transfer the skillet to the preheated oven and bake for about 15 minutes or until the internal temperature reaches 165°F (74°C).
7. Glaze Chicken: Once cooked, remove the skillet from the oven. Carefully transfer the chicken to a plate. Boil the remaining sauce in the skillet over medium-high heat for about 2-3 minutes to thicken it slightly.
8. Serve: Drizzle the thickened glaze over the chicken breasts.
