01 - Heat olive oil in a large pot over medium heat. Add onion, carrots, celery, and parsnip. Sauté for 5 minutes until vegetables begin to soften and release their aromas.

03 - Place chicken thighs into the pot. Pour in chicken broth and add bay leaf, thyme, oregano, turmeric, black pepper, and salt.
