This slow cooker version of the classic soup is super easy to make. We used chicken thighs because they're less expensive than breasts and tend not to dry out. If you like, skip the noodles and stir in your favorite cooked grain at the end.
The use of bone-in, skin-on chicken thighs is excellent for slow cooking as they render more flavor and remain succulent; browning them quickly before adding to the slow cooker can deepen the savory notes. Ensure vegetables are cut uniformly for even cooking. Adding the egg noodles only during the final 15 minutes is crucial to prevent them from becoming mushy and absorbing too much liquid. The fresh lemon juice at the end is vital; it brightens the entire soup, balancing the richness and elevating the overall flavor profile. Adjust salt and pepper at the end, tasting as you go. For an even richer broth, consider using homemade chicken stock.
