In a large pot, melt the butter over medium heat. Add in the diced onions, grated carrots, chopped celery, and minced garlic to the pan. Cook until vegetables are softened and fragrant, about 4-5 minutes.
Toss in the thyme leaves and bay leaves and cook for 1 minute more.
Pour in the chicken broth and bring it to a boil over high heat. Then reduce the heat to low and simmer for 20 minutes.
Add salt, pepper, onion powder, and turmeric to the soup and mix until all ingredients are combined.
Boil egg noodles in a large pot of salted boiling water (according to package directions). Once cooked, strain the noodles and toss them with 1 teaspoon of olive oil to avoid sticking. Set aside.
Slice chicken breast into small cubes and add it to the pot with noodles (you may use any kind of noodle). Cover with a lid and simmer for 15 minutes.
After the chicken and noodles are fully cooked, remove the bay leaves from the pot and discard them.
Drizzle with olive oil and garnish with freshly chopped parsley before serving.
