How do you make sweet potato noodles?

First of all, you’ll need a spiralizer. I use a Veggie Bullet, but there are tons of different models out there ranging from manual to automatic. As long as it gets the job done, go for it! If you don’t have a spiralizer, I’m noticing that grocery stores are selling pre spiralized veggies now! Such a great option, although far more expensive than doing it yourself, of course. If you’re not a huge sweet potato fan, you may sub carrot or zucchini instead. Or even rice or wheat noodles if you’re feeling really indulgent! This sauce would also taste particularly great on gnocchi. Mmm…

Once your noodles are cooked, throw your spinach in the skillet and mix well until wilted, about 30 seconds or so. Then remove your noodles from the heat and divide among four dishes. Or you may add them all to a larger serving platter if preferred and have everyone help themselves.

How do you make vegan Alfredo sauce?

Soak your cashews for 30 minutes in freshly boiled water. I use my kettle to boil water and pour the cashews and water into a heat proof bowl. Then drain and add to your blender along with all remaining sauce ingredients and process until smooth. That’s it! Super easy! This vegan Alfredo sauce is velvety smooth, full of flavour, and so satisfying. Pour a generous amount of this mouthwatering sauce over top your noodles of choice and enjoy!

If you’re so inclined, you may even sprinkle some Vegan Parmesan Cheese over top for some extra salty, cheesy flavour. But I promise these taste great as is!

Pin Recipe Print Recipe


  • 4 medium sweet potatoes spiralized
  • 2 cups baby spinach no need to measure, just grab a couple handfuls

For The Sauce

  • 1 cup raw cashews soaked in boiling hot water for 30 minutes
  • 1/2 lemon juiced
  • 3/4 cup water
  • 1/4 tsp garlic powder
  • 1/4 tsp onion powder
  • 1/8 tsp thyme
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • Optional Garnish Vegan Parmesan Cheese


  • Add your spiralized sweet potatoes in a large skillet with 2 tablespoons of water and sautรฉ over medium heat until softened, adding more water as needed to prevent sticking. This will take about 5 minutes. Then add your spinach and mix well to get them to wilt, about 30 seconds. Remove from heat.
  • Drain your cashews and add them to your blender, along with all remaining sauce ingredients. Process on high until smooth and creamy. Then pour your sauce over your sweet potato noodles and serve.


The sauce will thicken as it cools, so if you're working ahead, you may need to add more water or re-blend before ready to serve.
