Whisk together the balsamic vinegar, chicken stock, sugar, garlic and Italian herbs in a bowl, place the chicken breasts in the marinade, and marinate for 10 minutes on each side.
Heat the olive oil in a large frying pan over medium-high heat. Remove the chicken from the marinade and reserve the marinade. Place the chicken in the heated pan and cook until it starts to brown and is no longer pink inside, about 7 minutes per side. Pour the marinade into the pan, and cook until it thickens slightly, turning the chicken breasts over once or twice, about 5 minutes.
I recently tried balsamic vinegar on a chicken salad and thought how nice it was and so looked for a recipe using it. I found this recipe and decided to give it a go. I served it with pasta and tried it out on my children and they loved it and so did I! This will definately be a recipe that will be used again! - 24 Mar 2010
This was delicious and the kids all loved it!! I only browned the chicken though then poured over the marinade and let it slow simmer for 30 mins. Next time might put in less sugar but overall was very good!! - 18 May 2010
