Ingredients and Substitutions

Cashews give this pasta sauce its luscious, creamy consistency. You can use either raw or roasted cashews, just make sure they’re unsalted. Or if you prefer to use salted, reduce the salt in the recipe to taste.

Nutritional yeast adds a cheesy, umami flavor to this sauce. It’s often available at health food stores, or you can order it online.

I like to include a small amount of ground nutmeg in this sauce. It adds a lovely warm flavor. You can omit the nutmeg if you prefer.

How to Make Creamy Cashew Pasta Sauce

Place the unsalted cashews in a bowl and add water to cover. Let the cashews soak for at least 6 hours in the fridge (overnight is fine too).

Drain and discard the soaking liquid, then add the cashews to a high-powered blender. Add the cold water, nutritional yeast, garlic, salt, pepper, and nutmeg to the blender. Blend until smooth and creamy.
