Add the coconut oil, garlic, onions, celery and carrots to a large frying pan. Saute on medium heat while you cut up the chicken breasts into small, bite-sized pieces.
Add chicken to the pan. Cover and cook until no longer pink, about 10 minutes.
Remove the cover and cook for 2 minutes to allow the juices to boil off. If there are still juices, drain and replace in pan. Set aside.
Meanwhile, add cauliflower, chicken stock and onion salt to a large saucepan. Bring to a boil, reduce heat to simmer and simmer for 15 minutes, or until cauliflower is very tender.
Drain the cauliflower, reserving the liquid in a separate bowl.
Add ⅓ cup of reserved liquid to the jug of your high-powered blender with drained cauliflower. Blend until very smooth.
Pour cream sauce over cooked vegetables and meat. Stir to combine, then transfer to 6 small ramekins.
Meanwhile, prepare the pastry by adding coconut flour, egg, and coconut oil to your stand mixer, or to a bowl and mix with a hand mixer.
Once mixed well, add hot reserved cauliflower broth. This will help melt the coconut oil completely.
Separate the dough into 6 equal parts. Taking one part at a time, transfer to a piece of parchment paper, cover with a second piece of parchment and roll until about ⅛-inch thick. Cut a circle out of the rolled dough, I used a drinking cup. And carefully peel from the parchment, transferring to the tops of the ramekins. Poke the top with the end of a fork. Repeat with remaining dough.
When complete, place ramekins on a large baking sheet, brush the egg whites over top, and bake in preheated oven for 30 minutes, or until tops are golden and crisp.
Notes
Can it be frozen: I haven't tried it (because we ate them up too quickly!), but I think it would work! Eggs: are required in this recipe because coconut flour was used. Pastry: I am sure that this recipe would work with a different pastry on top. Feel free to use whatever recipe would work for you and your family.
