Spaghetti Squash Pizza Crust


Switch up your traditional pizza crust for this spaghetti squash pizza crust! It’s low-carb and grain-free, yet flavorful and the perfect base for your choice of toppings.

Man I am surrounded by some really talented friends in the wellness space and today I’m sharing a recipe from my friend, Rachel Mansfield’s new cookbook Just The Good Stuff. We met via the internet and then got to meet in real life when I visited New York a couple years ago. I was so excited when she announced she was publishing a cookbook and couldn’t wait to get my hands on a copy.

There are so many awesome recipes in her cookbook, but I was pretty pumped to see this spaghetti squash crust because although I adore a good cauliflower crust… I tend to eat a ton of cauliflower already. Plus I LOVE spaghetti squash, especially when roasted using my ring method and it makes such a delicious pizza crust. I also love that this crust is made with flaxseed so it doesn’t require an egg or cheese to hold it together like many veggie-based pizza crusts.

Just the Good Stuff Cookbook

Just the Good Stuff proves that living a healthy lifestyle doesn’t mean adhering to restrictive diets or giving up all the foods you crave. Rachel includes over 100 recipes using better-for-you ingredients, such as grain-free flours, collagen peptides, and natural sweeteners. I’ve been flipping through the book and found so many recipes I want to try (hello sea salt dark chocolate peanut butter bars), but thought I’d start with this pizza crust.

A Healthy Swap

I’m not going to lie and tell you that this pizza is a perfect substitute for real deal pizza. In my opinion, no veggie-based pizzas compare to regular pizza crust BUT it’s still so yummy and has all the pizza flavor you crave. Plus, I love that it packs in so many veggies and the fact that it doesn’t leave you feeling bloated and groggy after a few pieces. One thing to note with this variation is that the crust doesn’t get super hard or crispy so you’ll likely need a fork and knife to eat it. That said, I personally really like the texture!

Customize Your Pizza

I kept the toppings simple for my version, but you should make this pizza your own! You can add whatever toppings you like. I’ve tried this pizza a few ways and they were all delicious. Here are some ideas:

  • Traditional pizza sauce + shredded mozzarella + fresh basil
  • With herbed cashew cheese from Rachel’s cookbook… I made this and it’s so good!
  • Pesto + roasted veggies
  • BBQ sauce + chicken + caramelized onions
  • Breakfast pizza with eggs + cheese + turkey bacon
  • Sautéed greens + chicken sausage + fresh mozzarella

Spaghetti squash crust pizza cut into 8 slices on parchment paper and topped with basil, cheese and red pepper flakes.
Prep Time 40 minutes
Cook Time 45 minutes
Servings 1 small pizza


  • 1 large spaghetti squash, roasted (I used my ring method)
  • 1 flax egg, 1 Tablespoon ground flaxseed + 3 Tablespoons water
  • 1/2 teaspoon chili powder
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon ground oregano

Topping Ideas

  • pizza sauce
  • fresh basil leaves
  • grated or shredded cheese, dairy or non-dairy
  • cooked chicken sausage or vegan sausage, sliced
  • roasted veggies, sliced
  • crushed red pepper


  • Preheat the oven to 425°F and line a baking sheet with parchment paper.
  • In a large bowl, mix together the squash, flax egg, chili powder, garlic powder, and oregano.
  • On the prepared baking sheet, form the squash mixture into a pizza of your desired shape, about 1 inch thick.
  • Bake the crust just until it starts to turn golden, about 30 minutes. Remove it from the oven, add your desired toppings, and return it to the oven. I added pizza sauce, shredded mozzarella and fresh basil.
  • Cook until the edges are golden brown, 10 to 15 minutes more. Slice and serve warm. Leftover pizza will keep in an airtight container in the fridge for up to 5 days. Reheat it in the oven at 350°F.

      about how many cups of cooked spaghetti squash would you need to make 1 crust?

      Love the crust so much I made several more just for flatbread substitutes. For the flatbread I changed the spices, used a real egg, and cooked a bit longer for more crispiness. They heat up well too (more crispy in the oven but microwave is fine for a softer bread).

      Texture when it came out of the oven it tasted like normal spaghetti squash with sauce and had the same consistency as that, except with a lot of chili spice. Was a bit disappointed because of that, but it was edible (but not incredible).

      This is a good recipe, but I do want to know if you have used a pizza stone to bake the crust. I have a hard time removing it from the parchment paper and cutting on the paper was impossible. Thank you.

        Hey Mary – I made this on a baking sheet, not a pizza stone.

      I tried this recipe but it didn’t work :(. I used 1 egg and the tablespoon of flaxseeds with water… or was i only meant to use 1 of those?

      Also I mashed the butternut squash with a masher, was that right?

      any tips to make this work would be appreciated?

        Hey Amra,
        It was just supposed to be either the flax egg or you could use a regular egg, but just one or the other. And this recipe called for spaghetti squash, not butternut squash.
