Everybody loves pizza — but the carbs? Not so much. A single slice of regular pizza can send your carb count soaring, which is why I set out to create a truly satisfying low-carb version.

I’ll be honest, I was skeptical about cauliflower at first. But after a few experiments (and some flops), I finally nailed a crust that holds together, crisps up, and actually tastes like pizza. It’s not a traditional Italian pie, but it’s a delicious, cheesy compromise that I loved from the very first bite.

The trick? Baking the crust twice. That’s what gets the base firm enough to hold the toppings without turning soggy. With this method, you’ll have a cauliflower crust pizza that smells amazing, tastes fantastic, and has just 17 grams of net carbs for the whole pie — compared to more than 100 grams in a typical pizza.

Why You’ll Love This Cauliflower Crust Pizza

  • Low in carbs, big on flavor – Just a fraction of carbs for the whole pizza, compared to 100+ g in a traditional crust. Only 7.7 g net carbs per serving (2 slices)!
  • Crispy and sturdy – Unlike most cauliflower pizza crust, this one is sturdy. Baking the crust twice makes it firm enough to hold all your toppings without going soggy.
  • Naturally gluten-free and nut-free – Made without grains and almond flour, so it’s perfect for anyone avoiding gluten and nuts.
  • Cheesy and satisfying – Parmesan and mozzarella in the crust give it flavor and structure.
  • Easy to customize – Top it with pepperoni, veggies, or your favorite low-carb pizza toppings.

Ingredients & Swaps

  • Cauliflower rice – The base of the crust. Be sure to cook it well to remove moisture. You can also use frozen cauliflower rice (thawed and squeezed dry).
  • Egg white – Helps bind the crust without making it too soft. Whole eggs can be used, but the crust will be more fragile.
  • Mozzarella cheese – Use low-moisture shredded mozzarella for the crust, and fresh mozzarella for the topping.
  • Parmesan cheese – Adds flavor and extra structure to the crust. Pecorino Romano works too.
  • Seasonings – Garlic powder, oregano, basil, and a pinch of salt for a pizza-like flavor.
  • Olive oil or ghee – For greasing and brushing the crust to help it crisp up.
  • Toppings – Pizza sauce (I make my own Marinara Sauce), pepperoni, mushrooms, mozzarella, Parmesan, and fresh basil. Swap with your favorite low-carb toppings (olives, spinach, peppers, sausage).

Tips for Best Results

  • Remove as much moisture as possible – This is the single most important step. Whether you pan-cook or microwave the cauliflower rice, always squeeze it well before mixing.
  • Keep the crust thin – About 1/4 inch (1/2 cm) thick is ideal. Too thick and it will stay soggy in the middle.
  • Bake the crust twice – First bake it plain, then flip and bake again before adding toppings. This gives you a sturdy, crisp base.
  • Don’t overload toppings – Too much sauce, cheese, or veggies with high water content (like fresh tomatoes) will soften the crust.
  • Serve fresh – Cauliflower pizza is at its best right out of the oven. Reheating works, but the crust won’t be as crisp.

Cauliflower Crust Pizza FAQ

Why is my cauliflower crust soggy?

The key is to remove as much moisture as possible from the cauliflower. Cook it first to evaporate water, then bake the crust twice, flipping it once for best results, and then baking more once you add toppings. If you skip either step, the crust will likely stay soft.

Can I microwave the cauliflower rice?

Yes. Instead of cooking the cauliflower rice in a pan, you can microwave it for 5–6 minutes until soft. Let it cool slightly, then transfer to a nut milk bag or clean kitchen towel and squeeze out as much liquid as possible before mixing with the other crust ingredients.

Can I use frozen cauliflower rice?

Yes, but thaw it completely first. Then squeeze out excess water in a clean kitchen towel or nut milk bag before cooking, or the crust will be too wet.

Can I make this without cheese?

Cheese helps bind the crust and gives it structure. If you need it dairy-free, try using extra egg whites plus 2–3 tablespoons of almond flour or ground flax meal, but note that it won’t get as crispy as the cheese version, and the flavor will be different.

How do I make the crust hold together better?

Keep it thin — about 1/4 inch (1/2 cm) thick. A thinner crust dries out more and holds up better. Also, avoid too many watery toppings like fresh tomatoes or zucchini unless they’re pre-cooked.

Can I make this ahead of time?

Yes! You can bake the crust, cool it, and refrigerate for up to 3 days or freeze it. When ready to use, add toppings and bake again until heated through and crisp.

Storage Tips

This cauliflower crust pizza is best enjoyed fresh while the crust is still crisp. If you have leftovers, let them cool completely, then store in an airtight container in the fridge for up to 3 days. Reheat in a hot oven or air fryer to bring back some of the crispness—avoid microwaving, as it will make the crust soft.

You can also freeze the crust (before adding toppings) for a quick meal prep option. Bake the crust, let it cool, then wrap tightly and freeze for up to 3 months. When ready to use, bake from frozen for a few minutes before adding your toppings.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I have a question on the Pizza Base ingredients list.
How is the Mozzarella cheese and the Parmesan Cheese both 1/2 a cup when the grams are 60 and 30?
Thanks in advance!!!

Hi Lizzie, it's actually even less (30 grams should be just 1/3 cup parmesan - fixed). The reason for the different weights is different density.

This is such a good pizza crust.  Today I made a breakfast pizza for friends. Most of them  know I am Low Carb, but not necessarily Keto. I made the crust as shown and topped it with a Keto Alfredo sauce, mushrooms, onions, eggs, spicy pork sausage & cheese. My non-Keto Friends loved it.

I am making this tonight. I used a whole bag of trader joes cauli rice but the crust overall is pretty small! The photos make it seem much more substantial. Am I missing something??

Hi Talia, I don't think it's that small - have you tried weighing the ingredients? Here's an improved recipe - I recommend you use this one: Foolproof Pepperoni Cauliflower Pizza

Can you make these without the cheese and still get a good result?

I've tried it without the cheese in the crust. So basically i take 2 cups of cauli rice and dry them on medium heat on the pan. then mix it up with 3/4th cup of quick oats and an egg and mix the dough. Pat the crust in shape on a baking tray and bake till golden brown.
and to avoid the cheese in the topping you can simply use sour cream or ranch dressing to make it saucy.

Thank you! In this case we'd need to use almond flour to keep the recipe keto (oats are high in carbs).

I have not tried the cauli pizza recipe but I did try the recipe on www.dietdoctor.com for the vegeterian pizza and it was an instant hit with family and friends. In fact I even made it for my husband's birthday party and our guests loved it. Here is the link.

Sounds delicious!

I tried this on the weekend. It was lovely.
Thank You.

Thank you Leslie! Here is an updated version in case you want to check it out: Foolproof Pepperoni Cauliflower Pizza

Can you freeze these bases?

Yes, it should work but I'd probably bake the crust first (not freeze it raw) and freeze the crust separated by parchment paper (if making more crusts).

I did it today, it has a fantastic taste!! It didn't come up from the baking paper, but next time I will try it again. Thank you very much for the receipt!!

Thank you! I've fine-tuned this recipe and will soon post an updated version with a crunchier base and less carbs 😊

Wow this looks amazing!!! Just starting the LCHF diet and didnt realise how many awesome receipes are out there, thank you so much for sharing, am loving ur blog!

Thank you Sophie!

Thanks to all of you! 😊

Yummy! I made it last night (my second attempt) and it was fabulous! First time I made it I forgot to squeeze the juice out of cauliflower and it was too soggy :-(

This looks damn delicious. I will be making this pizza this upcoming weekend. *Drools*** 😊~~~~

Thanks for the recipe. I miss pizza... I'll try it soon!
