Preheat your oven to 450 degrees and line a baking sheet (round if you prefer) with parchment paper

In a large mixing bowl, combine the almond flour, tapioca or arrowroot, 3 Tbsp of the coconut flour, onion and garlic powder, Italian seasoning, and salt. Stir well to fully combine.

In a measuring cup, combine the water, oil, and vinegar , then pour into the dry mixture and stir with a wooden spoon until a dough forms.

Now stir in the whisked egg to combine well. Once you have a sticky mixture, you will slowly add the remaining coconut flour. I recommend adding a Tbsp at a time and mixing well, allowing the dough to sit a bit after each Tbsp to absorb the liquid, until you have a dough that's still a bit sticky yet able to be spread out. Don't add more than 3 additional Tbsp of coconut flour in this step, even if the dough seems sticky to work with - you can use extra tapioca to help spread it out.

Sprinkle extra tapioca or arrowroot on your parchment lined baking sheet, transfer the dough to the sheet and sprinkle with more tapioca/arrowroot. Work the dough into a 10 inch circle (12 for a very thin crust), then bake in the preheated oven for 10-15 minutes depending on how crisp you want the crust. I baked mine for about 10 minutes before adding my toppings, and baking again. Bake time will depend on the toppings you plan to add, how crispy you want the crust, and how thin you spread it out.

Top your crust however you like! Enjoy!
