Yes, cool the soup completely then freeze for up to 3 months. I highly recommend you DON'T freeze the soup with noodles, since they become soggy. Instead, if you plan on freezing the soup, boil the noodles separately and just add noodles to the soup you eat.  Thaw the soup overnight in the fridge, on the counter for several hours, or in the microwave. Then add a bit of extra chicken broth to loosen the soup, if needed.
