Garlicky Sweet Potato Noodle Pasta

Delicious vegan garlic Alfredo sauce over sweet potato noodles! This is a simple, healthy, flavourful, and satisfying dinner for everyone!

Garlicky Sweet Potato Noodle Pasta



  • 1 cup raw cashews
  • 3 cloves garlic ( add more or less to taste)
  • 4-5 Tbsp nutritional yeast 
  • 1/2 tsp sea salt
  • 2 tsp arrowroot starch (or cornstarch for thickening)
  • 1 1/2 – 2 cups unsweetened plain almond milk
  • 1 pinch red pepper flakes (optional//omit for less spicy)


  • 3 medium sweet potatoes (peeled and spiralized)

For Serving

  • Fresh chopped parsley
  • Sautéed kale
  • Vegan Parmesan Cheese
  • Red pepper flakes



  1. Add cashews to a small mixing bowl and cover with very hot water to soak for 30 minutes. Then drain thoroughly and set aside. (or soak cashews overnight or 6-8 hours in cool water).
  2. If serving with sautéed kale, prepare now and set aside until serving.
  3. While cashews finish soaking, peel and spiralizer potatoes using a veggie spiralizer on the thinnest blade. Or if you don’t own a spiralizer, you can use a vegetable peeler or julienne peeler instead. Set aside.
  4. Add soaked and drained cashews to a high-speed blender. Then add remaining ingredients: garlic, nutritional yeast, salt, arrowroot starch, and almond milk.
  5. Blend on high until creamy and smooth, scraping down sides as needed. Taste and adjust flavour as needed, adding more garlic, nutritional yeast for “cheesiness,” salt for saltiness, or a pinch of red pepper flake for heat. The sauce should be creamy, smooth, and pourable. If too thick, think with a bit more almond milk.
  6. Transfer sauce to a large, rimmed pan or pot and heat over medium-low heat until it just starts to bubble. Whisk as it heats, as it will thicken. Once bubbling reduce heat to a very low simmer to keep warm. The sauce will thicken, so thin with more almond milk if needed.
  7. Add 1 inch water to a large pot and top with a steamer basket (if you don’t have a steamer basket, see notes). Heat over medium-high heat and once bubbling, add potato noodles. Cover to let steam for 3-5 minutes. Be careful not to steam too long or the noodles can become soggy.
  8. Add your sweet potatoes to your sauce and gently toss to combine. If adding kale or other add-ins, add at this time.
  9. Serve as is or garnish with fresh parsley, kale, vegan parmesan, or red pepper flakes.
  10. This dish is best when fresh, as the noodles tend to get soggy after reheating, but the flavour is still delicious!


  • If you don’t have a steamer basket, sauté sweet potato noodles in a bit of oil in a large rimmed skillet for 5-7 minutes, gently stirring. 
  • To save time you can also buy store-bought spiralized sweet potato noodles.
