Step 1

Combine the cashews, broth, tomatoes, nutritional yeast, lemon juice, and garlic in a blender or food processor. Blend on high until the sauce is completely smooth. Stir in the basil and season with salt and pepper to taste.

Step 2

Transfer the pasta to a large bowl and toss it with the alfredo sauce. If the sauce is too thick, add a tablespoon or two of cooking water from the pasta.
