I’m combining my love of my nut-free dairy-free alfredo sauce with one of my favorite winter veggies ever, the spaghetti squash of course! This recipe is so flexible, I added some ham and broccoli into it, but you can add chicken or bacon and any veggies you fancy, making your own delish spaghetti squash alfredo. The outcome is super creamy and rich, it will warm you right up and become one of your favorite spaghetti squash recipes yet!

This also makes a great packed lunch, easy to re-heat and switch up with toppings/mix-ins to make it different each time. So don’t skimp out on using this for meal prep. If you haven’t had spaghetti squash before, it quite literally looks like spaghetti when you fork out the cooked squash pieces and holds any sauce really nicely. My paleo alfredo sauce is pretty famous in my spaghetti squash pastitsio (Greek Lasagna) recipe and is a staple over here – you will love it!

There are so many great dairy-free and vegan alfredo sauce recipes out there, but they usually include cashews (I even have one here) which is delish and fatty! But to make a nut-free version is a little different. The mix of cauliflower and coconut cream fits the bill perfectly.

  1. This Spaghetti Squash Alfredo came out delicious! My family was asking for more they minute they finished lol! So easy to make too!

  2. Is there a modified ingredient list to substitute for coconut milk, nutritional yeast, and arrowroot starch?

    Can almond milk be used instead? Or almond/coconut flour? Not sure what another substitute for nutritional yeast would be though…

  3. This spaghetti squash alfredo looks so delicious and is a great healthy version of a comfort classic. I’m going to use it to sneak some more veggies into my kids.

  4. I love how healthy this recipe is and it really does taste like a lighter version of fettuccine alfredo! I’ll be making this all winter long!

  5. This is such a healthy side or main dish to make this fall. I am so sure I will make it soon and yes, I’m gonna love it! Thanks for sharing, my lonely squash was waiting for this recipe 🙂

  6. This was an amazing recipe that my family really fell head over heels for. I have been watching our carbs and other things and this was perfect!! I will be making this again!

  7. Spaghetti squash is the most fun of all. The perfect pasta alternative. I know this would be a hit for dinner any night of the week.

  8. Thank you for this recipe; it is delicious! We love bold flavors so added two cloves of garlic to the blend and a bit more salt. It’ll definitely be a go-to dish for sure.
