Prepare the Chicken: Rinse the organic chicken parts under cold water and pat them dry with paper towels. Season generously with salt and pepper.
Saute The Aromatics: Add a splash of olive oil in a large stockpot over medium heat. Sauté the diced onions, carrots, leeks, celery, and minced garlic until they soften and release their fragrant aroma, around 5-7 minutes.
Add The Chicken And Vegetables: Introduce the seasoned chicken parts to the pot, followed by the chopped parsnips, turnips, Italian parsley stems, dill stems, bay leaves, and whole peppercorns. Stir everything together, letting the flavours meld.
Pour In The Liquid: Add the water or chicken broth to the pot, ensuring it covers all the ingredients. Bring the mixture to a gentle boil, then reduce the heat to low, covering the pot partially. Allow it to simmer for 2 to 2.5 hours, letting the flavours marry and intensify.
Skim And Season: Periodically skim off any impurities or foam that rises to the surface. Taste the soup and adjust the seasoning with salt and pepper as needed.
Strain And Serve: Carefully remove the chicken pieces from the pot and set them aside. Strain the soup through a fine-mesh strainer or cheesecloth into another pot or bowl, ensuring a clear, flavorful broth.
Serve And Garnish: Serve the soup hot, and put the cooked chicken pieces back in the bowl. Garnish with additional fresh parsley for a burst of freshness.
