My Spaghetti Squash Pizza Bake with Quinoa and White Beans is a protein-packed vegetarian pizza bake that’s perfect for a weeknight dinner or as the main dish for a vegetarian holiday feast.

Happy Thanksgiving week, friends! I feel like Thanksgiving is one of those holidays that is just so cozy. For us, it usually consists of eating too much while hanging out with wonderful friends. We usually have a very traditional Thanksgiving dinner at our house because my husband is quite obsessed with all things Thanksgiving. But if it were entirely up to me, I would be 100 percent OK with going less traditional and having a delicious dinner like this Spaghetti Squash Pizza Bake with Quinoa and White Beans.
I’m often asked about ideas for vegetarian and vegan holiday main dishes, and I think this recipe is perfect.
Spaghetti Squash Pizza Bake Recipe Ingredients
- Quinoa
- Spaghetti squash
- Beans – I used one 15-ounce can of white beans, drained and rinsed.
- Vegetables – This recipe calls for chopped red onion, diced red and green pepper, and minced garlic.
- Olive oil
- Spices – I used salt, black pepper, and dried Italian herbs.
- Tomato sauce – You can, of course, make your own tomato sauce. I used one 25-ounce can of store-bought sauce.

How To Make This Spaghetti Squash Pizza Bake with Quinoa and White Beans
- Cook quinoa according to package directions. Cut the spaghetti squash in half, scrape out the seeds, and then use a metal spoon to scrape out the “meat” of the spaghetti squash. You should get about 3 cups.
- Preheat the oven to 400 degrees F. Heat a large skillet over medium heat and add olive oil, then add the onion. Cook the onion for 2 minutes and then add the peppers, spaghetti squash, garlic, and all the spices. Cook the vegetables until tender, about 7 minutes.
- Next, add the quinoa, white beans, and tomato sauce to the skillet and mix until combined.
- Place the skillet into the oven and bake for about 15 minutes. Let cool for a few minutes before serving and garnish with basil or parsley, if desired.

Is there anything you can substitute the spaghetti squash out for?? Not in stock at two different grocers, ugh.
Oh no! Hmm, You could leave it out and add extra white beans or quinoa or you could try using a different variety squash puree. I hope that helps!
This looks great! What would you serve this with?
Thanks! I like to serve it with garlic bread and salad 🙂
This may be a silly question… but are you cooking the squash and quinoa first, or do they cook enough when they are in the oven? Thanks!
I scrape the spaghetti squash out and sauté it in a pan so it gets cooked and the quinoa goes in pre-cooked 🙂
I used black beans instead of white plus one jalapeno for kick. And then I baked it in (2) 9> round cake pans because I have a wok not oven skillet. Delicious and a lot of food, both pans are full. Not sure about freezing or reheats but fresh out the oven, this is delicious and nutritious. Thanks for sharing Izzy, You Make Today a Great Day.
I’m so glad you enjoyed it! Thank you for your comment! 🙂
We always do a traditional Thanksgiving meal in my family too, though I would be fine with pizza, or in this case, a spaghetti squash pizza bake! Love the flavors in here, Izzy! Especially with the quinoa and white beans, YUM!
