This Spaghetti Squash Crust is a grain-free alternative to traditional pizza and a great way to get more vegetables and fiber. Along with spaghetti squash, I used egg, mozzarella, and parmesan to bind everything together and seasoned it was garlic and oregano. This veggie crust is so tasty – it’s even good as a snack without the sauce and cheese on top.

How to Cook Spaghetti Squash

The first thing you’ll need for this pizza crust recipe is cooked spaghetti squash. You can cook spaghetti squash in the oven or, if you’re pressed for time, in the microwave.

How do you cook spaghetti squash in a microwave?

To cook spaghetti squash in the microwave, pierce it all over with a knife and heat for five minutes. Then continue to cook in two-minute increments until the skin gives when pressed.

Once done, cut it open, remove the seeds, and scrape the squash out with a fork. Spaghetti squash has a lot of water, so you’ll need to squeeze all the water out with a clean cheesecloth or dishcloth.

How to Get Crispy Spaghetti Squash Pizza Crust

I tested this spaghetti squash crust recipe dozens of times to get it perfect! The thinner you make the crust, the crispier it will be. I also found that parchment paper helped get the crust crisper than a Silpat.

This recipe makes four 7-inch rounds, which makes them easier to handle. Before baking, spray the crusts lightly with olive oil spray and bake for 15 minutes until golden. Then carefully flip with a spatula and bake for about six minutes until crisp.


  • Seasonings: Switch up the crust’s flavors by adding other dried herbs to the mix.
  • Toppings: Add your favorite pizza toppings to this crust. It’d be great with some pepperoni or sausage and veggies, like bell pepper, onion, and mushrooms.

  1. I had trouble imagining how squash could work as a crust, but I made this last night and was blown away by good it tastes! The crust was really crunchy and I made sure to squeeze out as much water from the squash as possible. Will definitely be making this regularly. 

  2. How does one shred parmesan cheese as opposed to grating it? Use a food processor?

  3. If I wanted to make a bunch of pizza crust can I freeze them to be used at a later date?

  4. Made this tonight and the whole family loved it. Mine was not crispy enough to be eaten with your hands, as you would a regular slice of pizza, possibly because I didn’t have shredded Parmesan, only grated (which the recipe says not to use). No matter to us, we ate it with a fork and knife and it was delicious. We made ours like a margherita pizza with fresh mozzarella and some basil on top. Love all of your recipes I’ve tried so far! Thank you.

  5. Do you have recipes that are weight watchers friendly? 

  6. This is THE BEST crust. It’s tasty and so easy to make. It’s become my go to crust on pizza night.

  7. Delish! Both my husband & I loved the flavor of the crust, (I could have left them in to bake a little longer to get them a little crispier…next time.) Paired this up with a side salad.

  8. We loved this & will be making it again!

  9. Did anyone else have a problem getting it to be crispy?? Maybe I didn’t get enough of the water out? I made a second batch that I baked for longer but even those were more omelette consistency than pizza crust??

  10. I’d like to make the spaghetti squash pizza, but have a severe egg allergy, and gluten allergy.  Can you make this with another bonding ingredient?

  11. I made this last night.  I cooked the squash in the oven first and then squeezed out the liquid.  This was a great supper last night and I served your Chicken parmisan on the side.   (I had some chicken tender leftovers from the night before from  that chicken meal)  I did put 4 small pieces of pepperoni on each pizza.  We loved it and will definitely do it again.

  12. Made tonight. Delicious! Topped with turkey pepperoni and green olives! Thank you Gina! Love your recipes!

  13. This was super tasty would make again

  14. No matter how I try to squeeze out the water I can’t get the spaghetti squash to form a pizza crust it is soggy and does not hold together. Any ideas on how to get all of the water out?

  15. The crust worked out really well! I would like to request you create a clan white pizza maybe with this crust 🙂 

  16. Delicious. Easy to follow

  17. Oh my gosh this is simply delicious!!!!  Even my husband who was skeptical said this was so so good.  Will definitely be making it again.

  18. My son and I loved this recipe. He thought the crispy crust could be eaten alone as a bread replacement. I agree. It was delicious.

  19. I made this today for lunch – added mushrooms and it was excellent. We have having your chicken schnitzel with potatoes and green beans tonight for dinner. 

      • This was delicious and I had great success making it vegan! Substituted apple sauce for the egg, and Trader Joe’s almond mozzarella and Parmesan substitute. I definitely increased the cooking time, probably 30 minutes before toppings and 10 minutes with, which may have had something to do with the substitutions. But it was delicious and worth the time!
