Nutritional yeast is a vegan substitute that has received a lot of recent attention, but what is it? And how can it be added to foods?

What Is Nutritional Yeast?

Nutritional yeast is composed of a deactivated yeast (Saccharomyces cerevisiae). Used in making beer (brewer's yeast) and leavening bread (baker's yeast). Nutritional yeast contains dead yeast cells without fermentation or leavening properties.

Nutritional yeast is grown in large tanks with molasses from either sugar cane or beets. It is an excellent protein, B complex vitamins, and minerals source. It is also a rich source of compounds known as beta-glucans that can support immune and gastrointestinal health.

How to Add Nutritional Yeast to Your Diet

Nutritional yeast has a mild, nutty, or cheesy flavor, making it more helpful to add to foods than Brewer's yeast, which has a more pungent bitter taste. Nutritional yeast's unique, appealing flavor makes it a popular vegan substitute for grated cheeses like parmesan. 

It can be commonly sprinkled not only on popcorn and cooked vegetables but pasta as well. In fact, for those looking for cheesy flavors in a diet that utilizes no animal products or by-products, nutritional yeast may feel like a miracle product because of its ability to mimic the flavors of parmesan, mozzarella, and even cheese-based sauces like alfredo. 

Nutritional Yeast Recipes

Even though nutritional yeast is one of the most versatile vegan substitutes available, it can still take work to determine the best recipes and uses. Here are some best-tasting recipe options that use this vegan substitute to improve the cheese flavor.

Creamy Alfredo Pasta With Vegan Parmesan

Italian cooking often uses rich, non-vegan ingredients like eggs, cheese, and cream. Still, with nutritional yeast, it's possible to craft Italian-style dishes like pasta and not lose any of the traditional flavors. This dish also adds vegan nutritional yeast parmesan to add to the cheesiness.

Ingredients for the pasta:

Instructions:

  1. Combine the cauliflower, veggie stock, yeast and all of the other ingredients in a large pot.
  2. Cook the ingredients for about three minutes or until the cauliflower softens.
  3. Place the cooked alfredo sauce into a blender and blend until the sauce achieves a thick consistency that's similar to traditional, non-vegan alfredo.
  4. Meanwhile, prepare the pasta based on the package's directions.
  5. Pour the sauce from the blender atop the pasta and serve with vegan parmesan.

Ingredients for the vegan parmesan:

Instructions:

  1. Combine all ingredients in a food processor and blend until it resembles parmesan cheese. 
  2. Serve atop the linguine and save the remainder by placing it in an airtight container and refrigerating it. This nutty and cheesy-tasting food additive can be used on pizza and other pasta dishes like pasta bakes.
