For a deeper flavor, try using bone-in, skin-on chicken thighs. Just be sure to remove the bones and skin before serving. Feel free to add other vegetables to the stew, such as potatoes, parsnips, or peas. A splash of dry sherry or white wine added to the stew in the last 15 minutes of cooking can add a wonderful depth of flavor. Leftover stew can be stored in the refrigerator for up to 3 days or frozen for up to 2 months.
