Following a "highly successful" cauliflower pizza crust test in the SoCal area, California Pizza Kitchen has decided to put the veggie-based crust on menus nationwide.

The cauliflower pizza crust game is hot right now, with one brand that offers it overtaking all frozen pizzas on Amazon in less than half a year. The gluten-free crust option is popular both because it has no wheat and that it's veggie-based, appealing to those looking to switch most of their carbs to produce or looking for veggie-centric meals.

A word of warning to those with Celiac disease, however: CPK isn't guaranteeing that trace gluten amounts won't be on their cauliflower crust. Current kitchen space limits their restaurants to only produce their four gluten-free regular pizzas in the gluten-free kitchen. The crust is certified gluten-free, but it'll be cooked in the same space as regular pizzas for now.

Guests can swap cauliflower crust onto any pizza on CPK's menu at any location, barring those in universities, hospitals, airports, and hotels. It'll be a $2.50 upcharge to get the crust typically, but CPK is waiving that through Feb. 9 as a way to get people to come in and try this increasingly popular pizza crust option for themselves.
