Prepare the ingredients by washing and cutting vegetables.
Heat a large pot over medium heat and add a splash of oil.
Sauté onions, garlic, and ginger until fragrant.
Add chicken and cook until lightly browned.
Pour in the chicken broth, carrots, celery, and lemon zest.
Bring the soup to a boil, then reduce the heat to simmer.
Simmer for about 20 minutes until the chicken is cooked through.
Remove the chicken, shred it, and return it to the pot.
Add lemon juice, salt, and pepper to taste.
Garnish with fresh parsley before serving.
