01 - In a large soup pot, heat 1 tablespoon of olive oil over medium heat. Add the diced onion, sliced carrots, and sliced celery, sautéing for 5 minutes until softened. Introduce the minced garlic and continue cooking for an additional minute until fragrant.
02 - Add the chicken breasts or thighs, chicken broth, bay leaf, dried thyme, dried parsley, salt, and black pepper to the pot. Bring the mixture to a rolling boil, then reduce the heat to a gentle simmer. Cook uncovered for 20 minutes, or until the chicken is thoroughly cooked through.
03 - Carefully remove the cooked chicken from the pot. Using two forks, shred the chicken into bite-sized pieces. Return the shredded chicken to the pot.
04 - Incorporate the egg noodles into the simmering broth. Continue to simmer for 8 to 10 minutes, or until the noodles are tender yet still firm.
05 - Taste the soup and adjust the seasoning as necessary with additional salt and pepper. Remove and discard the bay leaf before serving.
06 - Ladle the hot chicken noodle soup into individual bowls. Garnish with fresh chopped parsley if desired, and serve immediately.
