6-Ingredient Spaghetti Squash Pizza Casserole is dairy-free, egg-free, gluten-free and vegan. This dinner casserole is low-carb, hearty, and healthy!
Spaghetti squash is one of those ingredients that I adore but often forget about. Sorry, spaghetti squash! It's so versatile, usually on sale, and yields so much yumminess.
My friend Christina, over at The Whole Cook has an awesome recipe for Baked Spaghetti Squash Casserole and that's what inspired this recipe. One of my most popular blog posts, How To Cook Spaghetti Squash in the Oven, recently got a little makeover so I've been cooking with this squash a lot more than usual.
I realize that a lot (A LOT) of my recipes are either taco related or pizza, but I haven't heard any complaints! I could seriously live off tacos and pizza, they're just so delicious and always hit the spot. Sometimes though, I like to keep myself in check and eat a little healthier.
This recipe is perfect for when you're craving a cheesy and comforting pizza, but you haven't worked out all week... Oops, guilty!
This spaghetti squash pizza casserole is seriously so simple, as the oven does most of the work. It's one of those recipes perfect for weeknights that also serve as an awesome lunch the next day.
I used to hate leftovers but they truly make my life so much easier now that I'm cooking just about all my meals. If you have any casserole leftovers, just store the baking dish covered in your refrigerator and when you're ready to reheat, grab a serving, and pop it in the microwave.
How to Make Spaghetti Squash Pizza Casserole
Start by cooking down your onions and mushrooms, then stir in cooked marinara sauce, olives, and your other favorite pizza toppings. Transfer to a prepared casserole dish, top with vegan cheese and any additional toppings you have (maybe some basil or crushed red pepper). Bake for 25 minutes, remove from oven, and enjoy!

I've done something similar with gluten free pasta, but I really love the idea of the spaghetti squash. It is a great way to lighten up the meal. I'm glad to see that it reheats well, too. Perfect for my husband's lunches!

Hi Jenna,
wow, I never have seen anything like this!! Can’t wait to try this recipe, I know my family will love it! If I don't use marinara sauce, is it test well?
Jenna | The Urben Life
Thanks so much for your comment! I have not tested it without marinara so I'm not sure how it will turn out. Could you try a pesto or other sauce? If you try it, please let me know how it goes.

Nicole Kauffman
This looks awesome! How is vegan cheese? I'm lactose-intolerant and have struggled to find a good cheese replacement - especially one my husband will like!!
Jenna | The Urben Life
Thanks Nicole 🙂 I'm lactose intolerant too. I've been trying different vegan cheeses for years. My favorites are Daiya Cutting Board, Go Veggie, and So Delicious. I like cheese alternatives but my husband isn't a fan so he just takes his meals without it.
Alexandra @ It's Not Complicated Recipes
Another amazing recipe, Jenna 🙂
This sounds SO good, and I love the idea of using spaghetti squash!
Jenna | The Urben Life
I really appreciate that 🙂 Thanks so much!
Tatiana
I think I might actually be able to do this! My oldest daughter is a vegan, and I constantly struggle to find something I can make, something she can eat, and something the rest of the family would actually eat.
Jenna | The Urben Life
I hope y'all give it a try 🙂 I love that the whole family can enjoy this together.
Kelly Bolen
