Preheat your oven to 425°F (220°C).
Cut the cauliflower into florets and pulse in a food processor until it resembles rice.
Steam the riced cauliflower for about 5 minutes until tender.
Let the cauliflower cool, then wring out excess moisture using a clean kitchen towel.
In a mixing bowl, combine the cauliflower, mozzarella, Parmesan, egg, oregano, garlic powder, salt, and pepper.
Form the mixture into a dough-like consistency.
Place the dough on a parchment-lined baking sheet and shape it into a round crust.
Bake the crust for 25-30 minutes until golden and crispy.
Add your favorite toppings and return to the oven for an additional 10 minutes.
Remove from oven, slice, and enjoy!
