Preheat the oven to 200°C (400°F).

Rice the cauliflower by pulsing florets in a food processor until fine and rice-like.

Steam or microwave the cauliflower rice for 3-4 minutes, then let it cool slightly.

Place the cauliflower rice in a clean kitchen towel or cheesecloth and squeeze out as much moisture as possible.

In a mixing bowl, combine the cauliflower rice, Parmesan cheese, shredded mozzarella, egg, garlic powder, onion powder, oregano, salt, and black pepper.

Transfer the mixture onto a parchment-lined baking sheet and shape it into a pizza crust.

Bake for 15-20 minutes until golden and crispy around the edges.

Remove from the oven and spread a thin layer of tomato sauce over the crust.

Sprinkle with mozzarella cheese and bake for another 5-7 minutes, or until the cheese is melted and bubbly.

Garnish with fresh basil before serving.
