-
Blend the Sauce: Add all of the sauce ingredients to your blender. Blend on high speed until silky smooth and creamy, about 1 minute. Set the sauce aside while you prepare the noodles.

Sweet Potato Noodles with Vegan Alfredo Sauce Recipe FAQs
How do I choose the right sweet potatoes?
When picking sweet potatoes, look for those that are firm, with smooth skin and free of dark spots or blemishes. The sweeter and denser the sweet potato, the better the flavor for your noodles!
How should I store leftover sweet potato noodles and sauce?
Store leftover sweet potato noodles and vegan alfredo sauce in airtight containers in the fridge for up to 3 days. I recommend reheating gently on low heat to keep that creamy texture intact.
Can I freeze the vegan alfredo sauce?
Absolutely! You can freeze the sauce in ice cube trays for up to 3 months. To use, simply take out the cubes the night before and thaw in the fridge. When ready to enjoy, warm it over low heat, adding a splash of water if needed for creaminess.
What should I do if my sweet potato noodles are mushy?
If you find your noodles are too mushy, it might be due to overcooking. To prevent this in the future, cook them only until tender but still slightly “al dente.” When cooking, stir occasionally and check for doneness after 3 minutes.

This dish is nut-based due to the cashews, so be cautious of nut allergies! It is also gluten-free and vegan-friendly, making it suitable for a range of dietary preferences. For an added touch, swap out cashews for silken tofu if you need a nut-free alternative.
