7 Reviews

Cut the carbs and keep the flavor with this keto pizza with spaghetti squash crust. Indulge in this healthy, heavenly pizza!

I have mixed feelings about the keto diet, I’m not totally sold on any diet, more a balanced diet of many things vs full on cutting out, but I know a lot of you are all about it, so here is a keto approved pizza crust that will bring pizza night back into your week!

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!

How to Make Keto Pizza with Spaghetti Squash Crust

First of all, if you don’t already have a batch of our favorite pizza sauce already in the fridge, start by making that! Then we will jump into making the crust.

  1. Cut the spaghetti squash in half, scoop out the seeds and strings in the middle, and brush with olive oil.
  2. Place them cut side down on a cookie sheet lined with parchment and bake for 50-60 minutes.
  3. Remove them from the oven and let them cool.
  4. Use a fork to remove all the squash from the skin and place it on a fine mesh cheese clothe or dish towel.
  5. Squeeze the heck out of it removing as much moisture as possible.
  6. Whisk together the eggs and some of the mozzarella, then add the parmesan and spices and stir everything together.
  7. Add the cooled squash to the bowl and stir again.
  8. Press the squash into a 12″ circle on a parchment lined cookie sheet that has been sprayed with nonstick spray.
  9. Bake until golden brown.

Then your crust is ready to go! Add your sauce, cheese, and toppings and bake for 10 minutes more! See section below for some of our favorite topping combos.
