Preheat your oven to 425°F and line a baking sheet with parchment paper.
Steam the cauliflower florets until very tender, about 8-10 minutes, then allow to cool slightly.
Grate or pulse the steamed cauliflower in a food processor until it has a rice-like consistency.
Place the cauliflower in a clean dish towel or cheesecloth and squeeze out as much moisture as possible.
In a bowl, combine the drained cauliflower, eggs, almond flour, garlic powder, salt, and pepper. Mix well until a cohesive dough forms.
Press the cauliflower mixture onto the parchment paper, shaping it into a thin, even circular pizza crust.
Bake the crust for 15-18 minutes until it starts to turn golden and becomes crispy.
Remove from oven and spread the tomato sauce evenly over the crust.
Top with slices or torn pieces of fresh mozzarella.
Return the pizza to the oven and bake for an additional 5-7 minutes, until the cheese just melts.
Garnish with fresh basil before serving and enjoy your crunchy, flavorful cauliflower crust pizza.
