2
celery ribs, diced (about 1 cup)

Method
Heat the olive oil in a large stockpot or Dutch oven over medium heat. Once the oil is glistening, add the onion, leeks, celery, and carrots and cook, stirring often, until the onions are translucent, about 5 minutes. Stir in the garlic and cook until fragrant, about 1 minute more.
Add the chicken stock, bay leaves, thyme, and salt. Increase the heat to high and bring to a boil, then add the chicken. Reduce the heat to a simmer and cook until the internal temperature of the chicken reaches 165°F on an instant-read thermometer and the vegetables are tender, about 20 minutes.
Transfer the chicken to a cutting board. Let cool slightly, then use two forks to shred the chicken into 1-inch pieces. Discard the bay leaves and thyme sprigs.
Return the shredded chicken to the pot. Stir in the lemon juice, parsley, and pepper and cook for 2 to 3 minutes, or until the chicken is heated through.
Ladle the soup into bowls and top with parsley, pepper, and Parmesan, if desired.
