Prep: Preheat oven to 375 degrees F and line baking sheet with unbleached parchment paper.
Make "rice": Rinse cauliflower, remove the outer leaves, separate into florets and chop into smaller pieces. Process in a food processor in batches, until "rice" texture forms. Do the same with frozen (thawed) cauliflower and skip this step if using store-bought cauliflower rice.
Cook "rice": Transfer riced cauliflower on a prepared sheet pan or any oven safe baking dish and bake for 15 minutes or microwave in a microwave-safe bowl for 8 minutes. Transfer cooked cauliflower to a large bowl lined with double layered cheesecloth or linen towel, and let cool for 10-15 minutes or until safe to the touch.
Squeeze: Then hold onto 4 corners, twist cauliflower into a ball and squeeze the liquid out as hard as you can. Be patient and do this quite a few times until barely any liquid comes out. It takes about 3-4 minutes, you should get about 1 1/2 cups water out and your hands will be sore.
Make dough: Increase oven temperature to 450 degrees F. In a large bowl, add dry cauliflower, egg, cheese, Italian seasoning, salt and pepper. Mix very well with spatula until combined.
Form crust: Line same baking pan or pizza stone with new parchment paper (just make sure to scrape off any bits of cauliflower) and spray with cooking spray. Transfer cauliflower pizza dough in the middle and flatten with your hands until thin pizza crust of about 11 inches in diameter forms. Be sure to avoid thin edges, so push them in with a palm of your hand.
Bake it first: Bake crust for 20 minutes. If you would like more crispy crust, carefully flip it with spatula and bake for a few more minutes.
Bake pizza with toppings: Top cauliflower pizza base with your favorite toppings and bake again until cheese on top turns golden brown. Let cool 1-2 minutes, cut into 8 slices with a pizza cutter and enjoy!

Notes
Store: Refrigerate leftovers in an airtight container for up to 2 days.
Freeze: You can freeze 2 larger crusts or 4 smaller individual pizza crusts. Bake, cool and wrap crust in plastic wrap. Or place in a resealable extra large Ziploc bag. Freeze for up to 3 months. When you are craving pizza, place frozen crust on a pizza sheet and bake at 400 degrees F for 10 minutes. Then add toppings and bake for another 5-10 minutes.
Frozen cauliflower rice: No need to thaw, just cook from frozen.
Squeeze more than you think: The best advice I can give you for foolproof cauliflower crust is to squeeze cooled cauliflower very well. You really do need to squeeze out more water than you think you’ll ever be able to. Cauliflower should be pretty dry. I squeezed for about 3-4 minutes, until I couldn’t get any more liquid out. If your hands and arms are sore for a bit after, you did it well.
Double the recipe: Make 2 pizza crusts at a time if you want to feed more than two. Means two large heads of cauliflower.
Where can I find cheesecloth? You can find cheesecloth in most well-stocked supermarkets, dollar store or on Amazon for a very reasonable price. Linen towel works great too. You can throw both in the washer after.
What baking sheet can I use? Any sheet pan that can fit 11 inch wide crust or pizza stone works.
If you don't have a food processor: Grate cauliflower on a box grater or buy cauliflower rice.
