Melt the ghee in a medium pot over medium heat.
Add the diced onion, carrots, and celery, sautéing for 5 minutes until the vegetables begin to soften.
Stir in the cubed chicken breast and cook for 3-4 minutes until the exterior is no longer pink.
Pour in the chicken bone broth, sea salt, black pepper, and dried thyme, then bring the mixture to a gentle simmer.
In a small bowl, whisk together the cassava flour, baking powder, and chopped fresh parsley.
Add the water to the flour mixture and stir until a thick, tacky dough forms.
Using a small spoon, drop rounded tablespoons of the dough directly onto the surface of the simmering soup.
Cover the pot with a tight-fitting lid and simmer on low for 10-12 minutes without lifting the lid.
Remove from heat once the dumplings are firm and the chicken is cooked through, then serve immediately.
