Mix in Veggies: Stir in the diced carrots and celery, then pour in the chicken broth.
Add Chicken and Herbs: Add the shredded chicken, fresh thyme, and bay leaves. Bring the mixture to a boil.
Let It Simmer: Reduce heat to low and let the soup simmer gently for 15-20 minutes, allowing the flavors to meld and the vegetables to soften.
Cook the Noodles: Add the uncooked egg noodles to the pot and cook them according to the package instructions, typically about 7-8 minutes, until tender.
Final Touches: Remove the bay leaves, season the soup with salt and pepper to taste, garnish with fresh parsley if desired, and serve warm.
Notes
For a richer flavor, roast the vegetables before adding them to the soup. This soup can be made in a slow cooker as well.
