Heat olive oil in a large dutch oven or heavy pot over medium to medium-high heat until hot and shimmering.
Add carrots, celery, and onion to the pot. Sauté on medium heat for around 10 minutes until the veggies are softened.
Stir in garlic, turmeric, thyme, rosemary, lemon zest, salt, pepper, and optional cayenne. Sauté over medium heat for about 1–2 minutes until garlic is fragrant.
Stream in chicken broth while adding one bay leaf and the juice of half a lemon. Stir well to combine before bringing it all to a boil over medium-high heat.
Once boiling, add in your egg noodles and shredded chicken. Bring back to a boil before covering and reducing heat to low. Simmer over low heat for about 10–15 minutes until the pasta is soft.
Remove from heat once cooked through. Taste your soup and add additional salt & pepper according to preference. Stir in chopped parsley before serving.
