Sauté veggies – In a large soup pot, heat olive oil over medium heat. Add onion, garlic, carrots, and celery. Cook for 5 minutes until softened.
Simmer broth – Pour in chicken broth, add bay leaves, thyme, salt, and pepper. Bring to a boil, then reduce to a simmer for 15 minutes.
Add chicken – Stir in shredded chicken and continue simmering for another 10 minutes.
Cook noodles – Add egg noodles directly into the pot and cook until tender, about 8–10 minutes.
Finish & serve – Remove bay leaves, taste, and adjust seasoning. Ladle into bowls, garnish with parsley, and serve hot.
