Cut your cauliflower head into small pieces (remove green stem).
Add to a food processor. Pulse the cauliflower until it resembles small crumbs.
Add all the cauliflower crumbs to a kitchen towel or cheesecloth. Twist the cloth until water from the cauliflower comes out. Continue to squeeze until no more water comes out.
Add the cauliflower to a large bowl. Add in your eggs, flour, parmesan cheese, salt, and pepper. Mix.
Preheat your air fryer to 400 degrees. You do this by setting your air fryer to the temperature for about 5 minutes.
Cut out parchment paper the size of your Air Fryer. (This is not necessary, but it does help in the transfer of the pizza to the air fryer. You can also just use a spatula to transfer.) Take 2 tablespoon of your cauliflower pizza into the palm of your hand. Roll in a ball, and then flatten into a thin layer. Add as many pizzas as you can to your parchment paper. My air fryer will fit 4 at a time.
Cook at 400 degrees for 8 minutes. Flip the pizza over and cook at 400 degrees for 3-4 minutes (depending on your preference of softness to crunchiness).
Flip the pizza back over again where the first side is on the bottom again. Add your pizza sauce, cheese, and 3 pepperonis’. Cook again at 360 degrees for 4 minutes.
Remove with a spatula to your plate or serving dish. Top with parsley, oregano, parmesan cheese, etc. and enjoy!
