Creamy spaghetti squash “carbonara” is a perfect fall pasta alternative that uses spaghetti squash “noodles”. Creamy paleo cashew sauce will give that extra creamy flavor and makes sure that all the carbs cravings are gone.
Pumpkin & Pasta ?!
If you would have told me to make a carbonara out of pumpkin eight years ago, then I would probably had a strange look on my face. That sounds so unreal to taste good. However, if you have already tasted my butternut pumpkin (squash) “carbonara” (recipe here), then you might love this spaghetti one as well.
Culinary Alchemy
The first time I learned about spaghetti squash when I read this article at the Kitchen. It explains perfectly the culinary alchemy behind this special pumpkin texture. Spaghetti squash has its name for a reason, and I believe it’s magical! It’s one of my favorite pasta alternatives together with zucchini noodles (zoodles) recipes (chicken recipe here are mushrooms one here).

We’ve made spaghetti squash many times, but it’s never been as good as when we baked it this way. Thanks so much for the idea!
