To begin, dice the onion, carrots, and celery. All of the pieces should be 1/2 inch or so. Cut the chicken breasts into 3/4 inch pieces. Mince the garlic.
In a Dutch oven, heat the butter over medium heat. Add in the carrot, celery, and onion and cook until the onions are translucent – about 2 or 3 minutes. Add in the chicken and cook until it is opaque.
Pour in the chicken broth.
Add in the salt, black pepper, thyme, turmeric, and the bay leaf. Bring it to a boil, reduce heat to medium-low, cover, and simmer together for 1 1/2 hours.
Bring the soup up to a boil and add in the egg noodles. Cook until the noodles are done. Give the broth a taste and add salt if needed.
