Ingredients

For the Crispy Crust:

  • 2 cups finely grated cauliflower, riced (approx. 300g)
  • 2 cups shredded mozzarella cheese (plus extra for topping later)
  • 2 large eggs
  • 1/4 tsp Himalayan pink salt

For the Keto Pizza Sauce:

  • 5 oz (approx. 10 tbsp) concentrated tomato paste
  • 1/4 cup water
  • 1/2 tbsp olive oil
  • 1/2 tsp dried oregano
  • 1/2 tsp dried basil
  • 1/4 tsp garlic powder
  • A pinch of black pepper

Suggested Toppings:

  • Fresh mushrooms
  • Sliced tomatoes
  • Pepperoni or sausage
  • Black olives
  • Fresh basil leaves

Step-by-Step Instructions

  1. Preheat & Prep: Preheat your oven to 200°C (400°F). Line a large baking tray with parchment paper. (Do not use aluminum foil, or the crust will stick!)
  2. Prep the Cauliflower: If using fresh cauliflower, grate it finely. Microwave or steam the riced cauliflower for 5 minutes to soften it.
  3. The Crispy Secret: Allow the cauliflower to cool slightly, then transfer it to a clean kitchen towel or cheesecloth. Squeeze as much water out of the cauliflower as humanly possible. This is the most important step for a crispy crust!
  4. Mix the Dough: In a large mixing bowl, combine the dry, squeezed cauliflower, the 2 cups of mozzarella cheese, the eggs, and the salt. Mix thoroughly until it forms a cohesive "dough."
  5. Shape the Crust: Transfer the mixture onto your parchment-lined tray. Use your hands or a spatula to press it out into a thin, even layer, about 1/4-inch thick. You can shape it into a circle or a large rectangle.
  6. First Bake: Bake the crust bare for 15 minutes until it is firm to the touch and golden brown around the edges.
  7. Make the Sauce: While the crust bakes, whisk all the keto pizza sauce ingredients together in a small bowl.
  8. Top & Final Bake: Remove the baked crust from the oven. Spread your sugar-free sauce evenly over the top. Add your extra mozzarella cheese and favorite toppings. Return to the oven for another 8 to 10 minutes until the cheese is melted and bubbly.

Slice, serve, and enjoy your healthy, cheesy low-carb pizza!

💡 Ketoavie Pro Tips

  • Dry Cauliflower is Everything: We cannot stress this enough. If you don't squeeze the water out, you will end up with a soggy casserole, not a pizza. Squeeze it twice!
  • Keep it Thin: Press the dough out to 1/4-inch thickness. If it is too thick, the center will remain soft and mushy.
  • Broil for Extra Crunch: For an ultra-crispy finish, move the pizza to the lower rack for the main bake, and hit it with the broiler for the final 1 to 2 minutes after adding toppings.
  • Storage: Store leftovers in the fridge for up to 2 days. Reheat in a dry skillet or an air fryer to revive the crispiness. You can also freeze the pre-baked, un-topped crust between parchment paper for up to 1 month.

Frequently Asked Questions (FAQ)

1. Why is my cauliflower crust soggy?
You did not squeeze enough water out of the cauliflower. Cauliflower holds a massive amount of liquid. You must microwave/steam it first, let it cool, and then wring it out forcefully in a towel until it feels dry and crumbly.

2. Can I use frozen cauliflower rice?
Yes, it works perfectly! Thaw it, steam it for 5 minutes, and then squeeze it extra well. Freezing actually breaks down the cell walls and releases more water, so be prepared to squeeze it twice.

3. Does this taste strongly of cauliflower?
It has a very light cauliflower taste when plain, but the baked mozzarella and eggs mellow it out beautifully. Once you add sauce, pepperoni, and herbs, most people don't even notice the vegetable base.

4. Can I make this crust without mozzarella?
Mozzarella is the primary binder that gives the crust its chew. You can substitute 1 cup of parmesan cheese plus 1 extra egg, but be aware that the resulting crust will be more brittle and lack the traditional pizza texture.

5. Is tomato paste keto-friendly?
Yes, in small amounts. Because tomato paste is highly concentrated, using 5 oz for an entire large pizza only yields about 10g of net carbs for the whole pie (about 1.2g per slice). This is vastly lower than using store-bought pizza sauces, which are usually loaded with added cane sugar.

6. Can I make mini pizzas instead?
Absolutely. Divide the dough into 4 small rounds on the same baking tray. They will bake in roughly the same amount of time.
