01 - In a large pot, heat a small amount of oil over medium heat. Add the onion, carrots, and celery. Sauté for 4–5 minutes until softened. Add the garlic and cook for 1 minute more until fragrant.
02 - Pour in the chicken broth and add the chicken breasts, bay leaf, thyme, and dried parsley. Bring to a gentle boil, then reduce the heat and simmer for 20–25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F.
03 - Remove the chicken breasts from the pot and shred the meat using two forks. Set aside.
04 - Add the egg noodles to the simmering broth and cook for 7–8 minutes, or until tender.
05 - Return the shredded chicken to the pot. Season with salt and black pepper to taste. Remove and discard the bay leaf.
06 - Ladle the soup into bowls and garnish with fresh chopped parsley if desired. Serve hot.
