How long can chicken noodle soup simmer?

Chicken noodle soup can simmer for up to 2 hours, depending on the desired consistency and flavor intensity. A longer simmering time allows the flavors of the chicken, vegetables, and broth to meld together and create a more flavorful soup. However, it is important to monitor the soup to ensure it does not overcook or reduce too much, as this could result in a loss of flavor and texture.
