Chop onion, carrots and celery and place in mixing bowl.
Place chicken (do not chop or cut) and vegetables in Crockpot, then fill with water to about an inch of the top of the Crockpot.
Add all spices and Better Than Boullion, then stir thoroughly with a large mixing spoon, making sure that the Better Than Boullion is fully dissolved.
Cover and cook on low for 5-6 hours or on high for 2-4 hours (I recommend using the low method). Stir occasionally (it's okay if you won't be home to do so). note: noodles will be prepared right before serving so they won't be mushy
Using a slotted spoon, remove chicken from Crockpot and place into a medium mixing bowl or stand mixer bowl (I prefer using a stand mixer). Shred chicken using forks or on the lowest setting for the stand mixer (make sure not to over mix the chicken or it will get mushy) to desired shred size. After shredding, add chicken back to Crockpot and stir.
Prepare noodles according to package instructions (only make the amount you need, save the rest for leftovers), then drain and set aside. Ladle chicken soup into serving bowls and add desired amount of noodles to each bowl. Serve with crackers!
