Heat 2 tbsp olive oil in a large pot over medium heat. Add the chopped onion, carrots, and celery. Sauté for about 5 minutes until softened.
Add the minced garlic and cook for another 1 minute, stirring frequently.
Pour in 8 cups chicken broth, then add the dried thyme, salt, and black pepper. Bring to a simmer and cook for about 10-15 minutes until the vegetables are tender.
Stir in the shredded chicken and egg noodles. Cook for another 8-10 minutes, or until the noodles are tender.
Adjust the seasoning if needed, adding more salt, pepper, or thyme to your liking. Garnish with fresh parsley if desired. Enjoy!
