Dice the chicken breast into bite-sized pieces and season with half of the salt and pepper.
In a medium pot, melt the ghee over medium heat and sauté the diced onion, carrots, and celery until the onions are translucent.
Add the minced garlic and fresh thyme to the pot, stirring for one minute until fragrant.
Pour in the chicken bone broth and bring the mixture to a gentle simmer.
Add the chicken pieces to the pot and cook for 5 minutes.
While the chicken simmers, whisk the flour, baking powder, and remaining salt and pepper in a small bowl.
Stir in the water and half of the fresh parsley to the flour mixture until a soft dough forms.
Drop small spoonfuls of the dough into the simmering broth, cover the pot tightly, and steam for 10 minutes without lifting the lid.
Garnish with the remaining fresh parsley and serve immediately.
