Heat the oil in a large pot over medium heat.
Add the onion, carrots, and celery. Sauté for 5-7 minutes until softened and fragrant.
Stir in the garlic, ginger, and turmeric. Cook for another 1-2 minutes.
Pour in the chicken broth. Add the chicken pieces, bay leaves, thyme, and a pinch of salt/pepper.
Bring to a boil, then reduce to a simmer.
Cover and simmer for 20-30 minutes until the chicken is cooked through.
Remove the chicken, shred it with two forks, and return it to the pot.
Add the noodles and cook according to package directions until tender.
Taste and adjust seasoning—add lemon juice here if using.
Remove bay leaves and serve hot, garnished with fresh herbs.
