Sweet Potato Noodles with Creamy Cashew Sauce

Sweet Potato NoodlesWhen it comes to pasta—in my opinion, the creamier the sauce, the better. Anyone else agree?

Now, pair that creamy sauce with a slightly sweet, vibrant, and perfectly textured “noodle”.

Say hello to my Sweet Potato Noodles with Creamy Cashew Sauce!

sweet potato pastaIf you’ve yet to explore the spiralized veggie world, your mind is about to be blown. To be honest, I’ve had some not-so-great spiralized veg attempts, but the sweet potato was not one of them. In fact, sweet potato noodles are incredibly easy to cook + even hold up as leftovers!

Paired with the delicious sweet potato noodle is my take on a vegan Alfredo sauce. It is perfectly rich, thick, cheesy, and creamy—what is not to love? 

Soak those cashews, throw the sauce ingredients in the blender, sauté up the sweet potato, toss it all together and you’ve got yourself a hearty, 100% plant-based noodle dish.
