Typically, white sauce is heavy in dairy products and therefore not plant-based or vegan. White sauce, also known as béchamel sauce, is often used in French and Italian pasta recipes, such as lasagna. If you want to make a traditional white sauce that is vegan, you need to swap the dairy milk for a dairy-free alternative and use vegan butter or margarine. To add some cheesy flavor, a good pinch of nutritional yeast is highly recommended! However, the low-fat white sauce for our easy vegan pasta recipe is not made with any flour or butter at all — it’s an entirely whole food plant-based yet really flavorful dairy-free white sauce that only requires a handful of staple ingredients.
