Dice the chicken breast into bite-sized pieces and finely chop the carrots, celery, and onion.
Heat the ghee in a small pot over medium heat. Add the chicken, carrots, celery, and onion, sautéing for 5 minutes until the vegetables soften.
Pour in the chicken bone broth, dried thyme, sea salt, and black pepper. Bring the mixture to a gentle simmer.
In a small bowl, whisk together the almond flour, tapioca starch, and baking powder. Add 1 tablespoon of the warm broth to the flour mixture and stir until a thick, sticky dough forms.
Scoop small spoonfuls of the dough and drop them carefully into the simmering broth. Do not stir.
Cover the pot with a tight-fitting lid and reduce heat to low. Steam for 8-10 minutes until the dumplings are firm and the chicken is fully cooked.
Garnish with freshly chopped parsley and serve warm in a shallow bowl.
