A frozen cauliflower rice pizza crust lives or dies on one number: how much water leaves the cauliflower before it reaches the oven. Steam the bag, wring it through a towel until the liquid stops running, and the vegetable that usually slumps into a wet mat bakes into a base with a crisp freckled rim and slices firm enough to lift by hand. It is a one-hour keto dinner from one bag, one egg and two cheeses, at 7 g net carbs a serving.

Why this cauliflower crust works
- The bag has already done the ricing. Frozen riced cauliflower comes in a fine, even grain; a food processor leaves wet chunks that steam from the inside and soften the base around them.
- Steam first, squeeze second. Heat ruptures the cell walls so the water can leave. Wringing raw cauliflower rice yields a fraction of the liquid.
- Two cheeses, two jobs. Mozzarella melts into a net that binds the grains; hard Parmesan is dry and browns the surface without adding liquid. That pairing is what lets a keto cauliflower pizza crust behave like dough.
- It bakes naked before it bakes topped. Twenty bare minutes, with a flip halfway, set the structure before any sauce touches it.

Equipment
How to make it
- Heat the oven. 425°F (220°C), rack in the lower third, parchment on the baking sheet. The low rack browns the underside, which is where sogginess starts.
- Steam the cauliflower from frozen. Tip all 24 oz (680 g) into the bowl, cover, and microwave on high for 7 to 8 minutes, stirring once, until no icy patches remain and the bowl steams. On the stove, steam it covered for about 8 minutes.
- Cool it, then wring it dry. Spread it on a plate for 10 minutes so it is warm rather than scalding, then twist it through the towel in two batches. You should collect 1 to 1 1/4 cups (240 to 300 ml) of cloudy liquid. Stop when the grains feel like damp crumbs and no longer clump in your fist.
- Mix the dough. Combine the squeezed cauliflower with the egg, mozzarella, Parmesan, almond flour, Italian seasoning, garlic powder, salt and pepper. Work it with a fork, then your hands, until it gathers into one ball that holds its shape.
- Press the round. Press the ball on the parchment to an 11-inch (28 cm) circle about 1/4 inch (6 mm) thick, leaving the outer inch thicker as a rim. Even thickness matters more than a neat edge: thin patches scorch before the middle sets.
- Bake it bare, and flip it. Bake 15 minutes, slide the spatula under the crust, flip it onto a fresh sheet of parchment, and bake 5 to 7 minutes more. Both faces should be deep golden with dark freckles at the rim; a pale crust will bend.
- Top it lightly and finish. Keep toppings to about 1/3 cup (80 ml) sauce and 1 cup (113 g) cheese for the whole round, since anything heavier waterlogs the surface you just dried. Bake 6 to 8 minutes, until the cheese blisters.
- Rest before slicing. Move the crust to a wire rack for 5 minutes; cooling on the hot pan traps steam underneath. Cut into 8 wedges.
Practical cooking tips
- Measure the water you remove. If the towel yields much less than 1 cup (240 ml), the cauliflower was not hot enough; microwave it 2 minutes more and squeeze again. This step separates a frozen cauliflower rice pizza crust that slices cleanly from one that folds in half.
- Let the dough cool before shaping. Pressing while the cheese is molten smears it into a greasy sheet; at room temperature it presses like putty.
- Do not skip the flip. The underside sits against parchment for 15 minutes and cannot brown. Five minutes face down is what gives you a cauliflower crust that doesn’t fall apart under a topping.
- Bake it darker than feels comfortable. Deep brown freckles read as burnt on wheat dough but as properly done on cauliflower.
Swaps and variations
- No almond flour. Use 2 tbsp (12 g) ground golden flaxseed. It binds as well and shifts a serving by about 6 calories down and 0.4 g fiber up, so net carbs stay at 7 g.
- Dairy-free. Swap both cheeses for 1 1/4 cups (140 g) starch-based mozzarella-style shreds plus 2 tbsp (12 g) nutritional yeast. Costed against typical shred labels that lands near 193 calories and 14 g net carbs a serving, so it becomes a low carb pizza crust rather than a keto one.
- Four personal rounds. Divide the dough into four 6-inch (15 cm) discs and cut the bare bake to 12 minutes plus 4 after the flip. Macros per round are unchanged and they keep their shape better in a container.
- Zucchini to use up? The same water-removal logic drives our keto lasagna with roasted zucchini noodles, where dry-roasting rather than wringing does the drying.
Storage and meal prep
Bake the crust bare, cool it fully on a rack, and it becomes the most useful thing in the fridge. Cooked food should be refrigerated within two hours, held at 40°F (4°C) or below and eaten within three to four days, per USDA Food Safety and Inspection Service guidance, and a plain frozen cauliflower rice pizza crust sits comfortably inside that window. Stack cooled rounds with parchment squares between them in a sealed container. To freeze, wrap each bare round and keep it up to two months, then bake it from frozen at 425°F (220°C) for 6 minutes before topping. Reheat topped slices in a dry skillet over medium heat for 3 to 4 minutes; the microwave turns the base limp. A fully topped pizza is the one thing that does not survive storage, because the sauce migrates into the crust overnight. Cauliflower pizza crust meal prep therefore works best as bare rounds kept apart from their toppings, the same make-ahead logic that runs through much of the recipe archive.

Frequently asked questions
Can you make a frozen cauliflower rice pizza crust without cheese?
Not with this method. The mozzarella is the binder, and the egg alone cannot hold 680 g of cauliflower together. If dairy is out, use the dairy-free shreds described above and accept the higher carb count, or add a second egg white and treat the result as a knife-and-fork base.
How to squeeze water out of cauliflower rice without burning your hands?
Let the steamed cauliflower sit on a plate for 10 minutes, then work in two small batches through a folded cotton towel. Warm cauliflower gives up far more water than cold, so ten minutes is the compromise: cool enough to hold, hot enough to release a full cup.
Do I need to thaw the cauliflower rice first?
No, and it is better not to. Thawing on the counter lets the grains soften and clump before heat reaches them, while cooking from frozen drives the moisture out in one go.
Why is my keto cauliflower pizza crust soggy in the middle?
Almost always under-squeezed cauliflower, too much topping, or both. Measure the liquid you extract, since under a cup for 24 oz (680 g) means going back for another round, and cap the sauce at 1/3 cup (80 ml). The lower rack and the halfway flip handle the rest.
Is this crust genuinely low in carbohydrate?
Yes. A serving carries 11 g of total carbohydrate and 4 g of fiber, leaving 7 g of net carbs, most of it from the cauliflower itself. Raw cauliflower runs roughly 5 g of total carbohydrate and 2 g of fiber per 100 g according to USDA FoodData Central, which keeps a whole 680 g bag inside a keto budget.
