Vegan Cooking 101: What is Nutritional Yeast?

If you’re new to vegan cooking, you might not be familiar with nutritional yeast. It’s a great ingredient to get to know though, as nutritional yeast is popular in many vegan recipes. Dishes like my Easy Vegan Lasagna, No Coq au Vin with Creamy Vegan Polenta and even Vegan Fettuccini Alfredo are all possible (and delicious) by using nutritional yeast as a vegan cheese substitute.

What is Nutritional Yeast

In its commercial form, nutritional yeast consists of pale, yellow flakes that, unfortunately, remind me of fish food more than anything else. Don’t be dissuaded by this though – nutritional yeast doesn’t taste (or smell) anything like fish food. On its own, the flavor is a little strong. It’s not “sprinkle it on some crackers” for happy hour cheeseboard substitute. However, it does work wonderfully to add a cheesy taste to vegan foods. It’s also more than just a flavor substitute. Nutritional yeast is packed with essential nutrients that are sometimes hard to come by if you’re on an exclusively vegan diet. Oh, and if you’re going to be cooking with it, you need to know its common nickname –“nooch.”

Here are some additional facts on nutritional yeast; it’s: 

  • gluten free
  • low fat
  • soy free
  • sugar free
  • a good source of Vitamin B12
  • A plant-based source of a complete protein (containing all nine essential amino acids)

What is Nutritional Yeast: A Good Source of Vitamin B12

Fortified nutritional yeast can be a good source of Vitamin B12 for vegans and plant-based eaters. One-quarter cup of nutritional yeast contains 17.60 mcg of Vitamin B12, with the recommended daily requirement being about 2.4 mcg/day.1 Many of my vegan recipes call for 2 tbsp to ¼ cup of nutritional yeast in their ingredients, so getting B12 this way is very possible.  

Vitamin B12 is an essential vitamin needed for cell division and blood formation.2 However, humans largely meet their need for Vitamin B12 through animal-products, so vegans need to be especially diligent in making sure that they are also getting it. Not getting enough Vitamin B12 in your diet can have severe consequences.3

What is Nutritional Yeast: A Good Vegan Source of a Complete Protein

Nutritional yeast is also a good source of a complete protein, containing all nine essential amino acids.4 One ¼ cup of nutritional yeast has 8 grams of protein. Not bad for a flavor-enhancer, eh? 

What is Nutritional Yeast

“Wait a second…,” you might be thinking. What does that even mean? A complete protein?

If you’re an omnivore, the concept of a complete protein isn’t something you need to think very hard about. Animal products are complete proteins. This means that they contain all nine of the essential amino acids, or the amino acids that are not produced by the human body but rather need to be consumed. In nutrition speak, you might often hear people ask, “but how do you get your protein?” when questioning a vegan diet. This naysayer favorite is easy to rebuff – plenty of vegan foods contain protein. What’s important though, is to make sure that the protein being consumed is the right kind of protein.

Nutritionists used to think that vegans needed to eat plant-based proteins in certain sequences to ensure that all nine essential amino acids were being absorbed by the body. Current opinions recognize that a variety in plant-based proteins throughout a vegan’s diet is sufficient. Variety being the operative word. So, sprinkle on that nutritional yeast generously!

What is Nutritional Yeast: Friend to the Elite (Athlete)

In my trip down the rabbit hole researching nutritional yeast, I also came across some information about the effect of nutritional yeast on energy levels, particularly in elite athletes. The research indicated that a small amount of nutritional yeast following intense training or exercise could improve energy levels and decrease susceptibility to upper respiratory infections. Check it out for yourself at  

Some Words of Caution Around Nutritional Yeast

Some time ago, I had a follower on Instagram express concern over my use of nutritional yeast. It alarmed me a little, so I did a little research on it. With respect to bad press, nutritional yeast does get some of it because of its chemical similarities to MSG. If you’re not familiar with MSG, it’s a long-vilified (but also long-ago-pardoned) flavor-enhancer that speaks directly to our tastebuds and screams the word “Umami!” Not up to speed on MSG’s current status? You can learn more about it here. If you’re short on time though, my research shows that the MSG-correlation shouldn’t be of concern.5

However, if you have certain autoimmune diseases, such as Crohn’s disease, consuming nutritional yeast is not recommended. You can learn more about that here and other rare, but possible, concerns with consuming too much nutritional yeast are covered here (including niacin, tryamine and fiber sensitivities).

My Favorite Vegan Recipes Using Nutritional Yeast

I’m particularly grateful for this vegan ingredient as it finds its way into many of my vegan recipes. It’s very helpful in combating the “but I could never give up cheese” argument for those who are interested in the vegan diet but see cheese as their major hurdle. Here are some of my favorite vegan recipes to hopefully convince you as well!
