Absolutely! To get the most flavor from the boneless-skinless chicken breast, searing it in the soup pot first is such a great way of bumping up the rich chicken flavor. Let it sit undisturbed until it is browned on the bottom, then stir it, so it doesn’t stick to the soup pot. Those tasty crusty bits on the bottom of the pot (fond) will add a ton of flavor to the soup. Remove it and keep it warm while finishing the soup, so that it does’t overcook and dry out.
