Creating Grandma’s Chicken Noodle Soup is simple when you follow these steps:

1. Prepare the Chicken: Place the whole chicken in a large pot and cover it with 12 cups of water. Bring it to a boil over medium-high heat.
2. Add Vegetables: Once boiling, add the carrots, celery, onion, garlic, salt, pepper, thyme, rosemary, and bay leaf. Reduce the heat to low and let it simmer for about 30 minutes.
3. Cook the Chicken: After 30 minutes, check if the chicken is cooked through. It should reach an internal temperature of 165°F (75°C). Remove the chicken from the pot and let it cool slightly.
4. Shred the Chicken: Once cool enough to handle, shred the chicken into bite-sized pieces, discarding the skin and bones.
5. Add Noodles: While the chicken cools, add the egg noodles to the pot and cook them according to package instructions, usually about 8-10 minutes.
6. Combine Chicken and Broth: Return the shredded chicken to the pot and stir to combine. Let it heat through for an additional 5 minutes.
7. Adjust Seasoning: Taste the soup and adjust the seasoning if needed. You can add more salt, pepper, or herbs to suit your preference.
8. Serve: Ladle the soup into bowls and garnish with fresh parsley.

These steps will guide you in creating this incredible soup effortlessly.
