Heat the olive oil in a large pot over medium heat and sauté the cubed chicken breast until browned on all sides.
Add the diced onion, carrots, and celery to the pot, cooking for 5 minutes until the vegetables begin to soften.
Pour in the chicken bone broth and add the fresh thyme, rosemary, sea salt, and black pepper.
Bring the stew to a gentle simmer, then reduce heat to low while you prepare the dumpling dough.
In a small bowl, whisk together the almond flour, tapioca starch, and baking powder with two tablespoons of the warm broth from the pot until a thick dough forms.
Drop small spoonfuls of the dough into the simmering stew, cover the pot with a lid, and steam for 5 to 7 minutes.
Remove the lid, gently stir in the coconut milk to create a creamy texture, and serve immediately.
