01 - Set oven temperature to 450°F (230°C). Place pizza stone on the center oven rack and allow to preheat thoroughly.
02 - Process cauliflower florets in a food processor until the texture resembles fine rice.
03 - Transfer cauliflower rice into a clean kitchen towel and squeeze firmly to extract as much liquid as possible.
04 - In a large mixing bowl, combine drained cauliflower, eggs, 1 cup shredded mozzarella, 1/4 cup Parmesan, oregano, garlic powder, salt, and black pepper. Mix until even.
05 - Line a pizza peel or baking sheet with parchment. Press cauliflower mixture onto parchment, shaping into a 12-inch round about 1/4 inch thick.
06 - Carefully transfer the crust with parchment onto the preheated pizza stone. Bake 12–15 minutes until golden brown and set.
07 - Remove crust from oven. Evenly spread pizza sauce across the surface. Distribute 1 1/2 cups shredded mozzarella, 1/4 cup Parmesan, and optional toppings as desired.
08 - Return assembled pizza to oven. Bake an additional 8–10 minutes until cheese is melted and bubbling.
09 - Allow pizza to cool for 3–4 minutes. Finish with fresh basil leaves if desired. Slice and serve immediately.
