Why does my chicken create so much liquid when cooked in the skillet?

Once you dice up your chicken and pop it into the skillet, try to leave it undisturbed for 3-4 minutes while it cooks. Once browned on that side, flip it and do not disturb it again until the other side is browned. This will help reduce the amount of liquid created in your skillet. If you do end up with too much liquid, and you want to reduce it due to seasonings and flavor that may be present, you can take the chicken out and put it on a plate. This will allow you not to overcook the chicken but also reduce the liquid left in the skillet and intensify the flavor that is left.
