Preheat the oven to 450°. Grab a baking sheet and line it with parchment paper. If you have a pizza stone, even better! (line the pizza stone as well) Take one head of cauliflower and do a rough chop to have medium-sized florets. Place the cauliflower florets into an S-bladed food processor, along with 2 cloves of garlic (this is optional). Pulse until it is a “rice” like consistency. I always pulse my cauliflower 10-15 times and it comes out perfect.
Transfer the riced cauliflower into a large bowl. Microwave the cauliflower for 5 minutes. This helps seam the cauliflower and will later help in extracting the moisture. If you prefer, you can line a baking sheet with parchment paper and bake the cauliflower in the oven for about 10 minutes to steam.
Now, transfer the steamed rice cauliflower to a cheesecloth clean dish towel. I like to let the cauliflower rice sit in a bowl lined with a cheesecloth, lightly salt the cauliflower, and let the moisture begin to seep as I prepare the other ingredients (about 5 minutes). Then, take the cloth and squeeze as much moisture out of the cauliflower as possible. You should squeeze out at least 2/3 cups. Drain as much liquid as possible.
Next, grab a clean, dry large bowl and add the cauliflower, gluten-free flour, baking powder, eggs, Italian seasoning, salt, and pepper. Mix the ingredients using a spatula. Form a ball with the dough and place it on the parchment-lined baking dish.
Place a sheet of parchment paper on top of the dough. Using your hands, gently press out the pizza dough into a circle. The dough should be about 1/2 inch to 1 inch thick (your preference). Remove the top layer of parchment paper and the dough is now ready for the oven! Place the dough in the oven and bake for 15 minutes, or until the edges become a golden brown.
While the dough is in the oven prepare the toppings. Once your toppings are prepared and cooked, top your Cauliflower Pizza Crust generously. Once your pizza has all of your desired toppings, bake it in the oven for an additional 8-10 minutes. Let the pizza cool for 5 minutes, then slice and feast on your delicious, healthy, gluten-free, cauliflower crusted pizza!
