In a large pot, heat the olive oil over medium heat. Add the diced onion, carrots, and celery. Sauté for about 5 minutes until the vegetables are softened.
Stir in the minced garlic and cook for an additional minute until fragrant.
Pour in the chicken broth and bring the mixture to a boil.
Add the shredded chicken, thyme, parsley, bay leaf, and season with salt and pepper. Reduce the heat to a simmer and let it cook for 10 minutes.
Add the egg noodles and continue to simmer for another 8-10 minutes, or until the noodles are tender.
Remove the bay leaf before serving. Taste and adjust seasoning if necessary.
Serve hot, garnished with fresh chopped parsley.
