I did all sorts of research on keto pizza crust and almost everything talked about fathead pizza dough. And while that sounded alright, I thought, let’s not even pretend to make a dough and just use spaghetti squash! You loved our zucchini pizza crust, so I thought…why not spaghetti squash?

We were coming off of our quarterly detox and trying to incorporate more veggies into our diet and fully expected the kids to pout and whine.

I prepped the crust that morning and then threw it together at dinner. I didn’t say a single word and just served it up. Not one peep and my 5yo had 4 pieces! While cleaning up it dawned on me that it was squash and told everyone and the kids were shocked!

This crust is not limp or soggy, and makes the perfect base for all your favorite pizza toppings!
