Preheat the oven to 450 F and line a baking sheet with parchment paper. Set aside.
Chop the cauliflower head into florets, removing any green leaves. If you have a kitchen scale, weighing out 600 grams of cauliflower is helpful to ensure you get the perfect crust.
Working in batches, place the cauliflower florets into a food processor and pulse for about 10 seconds or until the cauliflower is processed into pieces about the size of rice grains. Remove the cauliflower rice and place it in a microwave-safe bowl. Set aside and repeat with the remaining florets, until all the cauliflower has been riced.
Place the cauliflower rice in the microwave and microwave for about 7 minutes on high (5-7 depending on the wattage of your microwave). You want the cauliflower cooked enough to be able to easily remove most of the moisture by squeezing it. After it has cooked, remove it from the microwave and set it aside to cool.
While the cauliflower cools, whisk together the eggs in a large mixing bowl. Add the herbs, garlic powder, and salt and mix until there are no clumps.
Once the cauliflower has cooled enough to handle, fold a clean kitchen towel in half. Top it with several folded paper towels and place the cauliflower rice in the center of the towels. Grab the corners of the towel and pinch them together, gathering the cauliflower in the center. Twist the gathered portion of the towel and hold it over the sink or a bowl, pressing the cauliflower to remove moisture from it. Continue to press and wring it until about 1 cup of water has been removed.
Once most of the moisture has been removed from the cauliflower, add it to the bowl with the eggs, along with ¾ cup of parmesan, and ¾ cup of mozzarella. Mix together creating a dough.
Place the dough on the lined baking sheet. Press the dough down to flatten it so it is about ¼ inch thick and form the shape you want for your pizza crust using your hands. Ensure that the dough is an even thickness to allow for even cooking.
Place pizza crust in the oven and bake for about 15 minutes or until it becomes golden brown.
Remove the crust from the oven and set the oven to broil.
Top the crust with pizza sauce, the remaining 2 cups of cheese, and desired toppings. Place back in the oven for about 5 minutes or until the cheese gets melty and bubbly. Remove from the oven, slice, and enjoy.
