Sauté the Vegetables: In a large pot, heat the olive oil over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5-7 minutes, or until the vegetables begin to soften.
- Add Garlic and Broth: Add the minced garlic and cook for another 1-2 minutes until fragrant. Pour in the chicken broth, and stir to combine.
- Season the Soup: Add the shredded chicken, bay leaf, thyme, black pepper, and salt to taste. Bring the soup to a boil, then reduce the heat and simmer for about 20 minutes to allow the flavors to meld.
- Cook the Noodles: Add the egg noodles to the pot and cook according to the package instructions, typically about 8-10 minutes, until the noodles are tender.
- Finish the Soup: Once the noodles are cooked, remove the bay leaf and adjust the seasoning as needed. If desired, squeeze in the juice of one lemon for a burst of freshness.
- Serve: Ladle the soup into bowls and garnish with fresh parsley, if desired. Serve hot with crusty bread or a side salad for a complete meal.
