The Korean inspired marinated Gochujang spice chicken breast offer a quick fuss free meal. Chef recommendation for cooking the juiciest chicken breast. 1. In pan / grill over high heat add a dash of cooking oil. Pan sear each side for 1-2 min each. 2. When chicken is nicely caramelised, transfer to a 200 degree celcius oven and allow to roast for 8 min at 220C. Allow the chicken to rest for 5 mins before serving. This will allow juice to distribute throughout.
