Step 1

If you have a high powdered blender such as a Vitamix, Blendtec, or Breville you can skip to step If you don’t have a high-powered blender, you might want to boil the cashews first to ensure they are tender enough to blend into a smooth sauce. To do this add the cashews to a small pot and cover with water. Bring to a boil and cook for about 10 minutes until the cashews are very tender. Drain and rinse with cold water. You can now proceed to make the cheese sauce.

Step 2

Make the cheese sauce by adding 2 cups of water along with the cashews, nutritional yeast, cornstarch, miso paste, truffle oil, salt, garlic powder, and pepper to your blender until it is completely smooth. At this stage, the sauce will be quite watery. Set aside.

Step 3

Bring a large pot of water to a boil and then cook the pasta according to package directions.

Step 4

Drain the pasta and quickly rinse the pot to remove any leftover starch from the pasta water. Return the empty pot to the heat and pour in the cheese sauce. Cook over medium-high heat, stirring frequently and scraping the bottom of the pan with a spatula until the sauce thickens, about 5 minutes. Add the cooked hot pasta to the sauce and toss to coat. Serve hot.
