Keto Cauliflower Pizza Crust (Vegan)

This isn't a classic yeast dough, but a vegetable matrix. Our biggest enemy here is water: cauliflower is 92% water, which we must remove to get a crispy base instead of cooked puree. The binding agent is the gelling power of flaxseed instead of eggs.

Ingredients

Equipment Needed

  • Food processor (S-blade)
  • Clean kitchen towel or cheesecloth (for squeezing)
  • Parchment paper
  • Baking sheet

Allergen Information

⚠️ Wheat (unless certified GF Oats used)

Instructions

1

Mix the ground flaxseed with water and set aside for 10 minutes until it becomes jelly-like ('flax egg').

Tip: The mucilage in the flaxseed hull forms a hydrogel network when in contact with water; this will hold the dough together.
2

Pulse the cauliflower in a food processor into crumbs (rice-sized).

Tip: Don't over-process or it will become a puree, not crumbs!
3

Steam the cauliflower crumbs (5 mins in microwave or in a pan), let cool slightly, then place in a kitchen towel and squeeze out ALL the water. It's good when it comes together in a dry ball.

Tip: Heat weakens plant cells, allowing them to release water more easily. This is the most important step!
4

Knead the dry cauliflower, flour, spices, and flax egg into a dough ball.

Tip: The flour helps absorb remaining moisture.
5

Press the dough onto parchment paper into a circle about 1/4 inch thick. Pre-bake at 400°F (200°C) for 20-25 minutes until the edges start to brown and the surface is dry.

Tip: Pre-baking solidifies the structure. It wouldn't cook through in the middle with toppings on it.
6

Spread with sauce, sprinkle with cheese, and bake for another 10 minutes until cheese melts.

Tip: Don't overload with heavy toppings, as this crust is less sturdy than wheat dough.

Recipe FAQ

Why does the crust fall apart?
Because water remained in it. The cauliflower must be squeezed ruthlessly, almost bone-dry. If you think you're done, squeeze a bit more!
Can I use frozen cauliflower?
Yes, actually! Freezing damages cell walls, making it even easier to squeeze out water after thawing.
