Step 1: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.
Step 2: Prepare the cauliflower rice. Wash and trim the cauliflower, then cut it into florets. Pulse the florets in a food processor until they resemble rice or couscous. Be careful not to over-process, or it will become mushy.
Step 3: Cook the cauliflower rice. Transfer the riced cauliflower to a microwave-safe bowl. Cover and microwave on high for 5-7 minutes, or until tender. Alternatively, you can steam it on the stovetop. This step is crucial for making a firm Riced Cauliflower Crust Pizza.
Step 4: Remove excess moisture. This is the MOST important step for a crispy Riced Cauliflower Crust Pizza! Once cooked, transfer the warm cauliflower rice to a clean kitchen towel or several layers of cheesecloth. Allow it to cool slightly, then squeeze out as much liquid as humanly possible. You’ll be surprised how much water comes out! The drier the cauliflower, the crispier your Riced Cauliflower Crust Pizza.
Step 5: Make the crust mixture. In a large bowl, combine the thoroughly squeezed cauliflower rice with 1/2 cup shredded mozzarella, Parmesan cheese, the beaten egg, oregano, garlic powder, salt, and pepper. Mix well until everything is evenly combined and forms a sticky ‘dough’.
Step 6: Form the pizza crust. Transfer the cauliflower mixture to the prepared baking sheet. Using your hands, press the mixture firmly and evenly into a 10-inch circle or square, about 1/4 to 1/2 inch thick. Ensure the edges are slightly raised to form a crust. This firm pressing is key to a sturdy Riced Cauliflower Crust Pizza.
Step 7: Bake the crust. Bake for 20-25 minutes, or until the crust is golden brown and firm. It should be dry to the touch. Let it cool on the baking sheet for 5 minutes.
Step 8: Add toppings. Carefully remove the partially baked crust from the oven. Spread the pizza sauce evenly over the crust, leaving a small border for the edge. Sprinkle with your desired amount of mozzarella cheese and arrange your favorite toppings.
Step 9: Final bake. Return the pizza to the oven and bake for another 10-15 minutes, or until the cheese is melted and bubbly and the crust is golden brown and crispy. Keep an eye on the Riced Cauliflower Crust Pizza to prevent burning.
Step 10: Cool and serve. Remove the Riced Cauliflower Crust Pizza from the oven and let it cool on the baking sheet for a few minutes before slicing and serving. This helps the crust firm up even more. Enjoy your homemade Riced Cauliflower Crust Pizza!
