Gather Your Ingredients: Start by assembling all necessary ingredients on your countertop for an efficient cooking process.
Prepare Your Vegetables: Dice the onion, mince the garlic, peel and dice the carrots, chop the celery, and finely mince the parsley, setting it aside for later use.
Sauté Vegetables: In a large soup pot, add olive oil along with diced onion, carrots, and celery over medium heat; cook until softened, stirring occasionally for about six minutes.
Add Aromatics and Chicken: Incorporate minced garlic, dried basil, thyme, bay leaf, black pepper, and one teaspoon of salt into the pot; stir well before adding chicken breasts and covering them with chicken broth.
Simmer to Perfection: Cover the pot with a lid; bring everything to a boil then reduce heat to low; let simmer for one hour ensuring it bubbles gently throughout.
Final Touches: After an hour, remove chicken from pot; shred using two forks before returning it back along with egg noodles; boil until tender then finish off with fresh parsley before serving hot!
