What is Nutritional Yeast (Nooch)?

Although I assume that most of the non-vegans who read my blog are familiar with things like tofu and chickpeas, it’s occurred to me that there may be a few questions surrounding some of the lesser-known vegan/health food ingredients. So with that, I’ve added a new section to my blog called What’s That?, and every now and then I’ll write a post about one of these ingredients, and link to it when my recipes call for it.

What is Nutritional Yeast?

First up: Nutritional Yeast. Because (lacto-ovo) vegetarians get their cheese-fix from dairy, many of them are not familiar with this ingredient. But because it imparts a “cheesy” taste to food, it is loved by vegans and other people who do not consume dairy. It’s not something that you see used in a lot of commercial food products (to the chagrin of us vegans), so you kind of have to be “in-the-know” to have heard about it. But it’s not that difficult to find and it’s even easier to use, so I really encourage you to try it if you haven’t already.


  • It is a deactivated yeast and a fungus
  • It is produced by culturing the yeast with a mixture of sugarcane and beet molasses for a period of 7 days, then harvesting, washing, drying and packaging the yeast
  • The flakes are bright yellow in color
  • It is a complete protein, meaning it contains an adequate proportion of all nine essential amino acid that we need to function
  • It is a good source of protein and B vitamins (If you’re vegan, you should seek-out a brand that is fortified with B-12)
  • It is low in fat and sodium and is free of sugar, dairy and gluten
  • It has a strong nutty/cheesy flavor that can be added to any dish to impart a cheesy taste

Nutritional Yeast


  • Grind it in a food processor with an equal part of blanched almonds to mimic Parmesan – this is great sprinkled on pasta!
  • Add a tablespoon or two to risotto, quiches, cannelloni, stuffed mushrooms – anywhere you would normally use Parmesan or other cheese
  • Sprinkle it on popcorn
  • Blend it with nuts to make vegan cheese sauce, and soft or hard cheese

Where to Buy / What to Ask For

  • It is sold as “savoury yeast flakes” in Australia and Brufax in New Zealand
  • Do NOT confuse it with Brewer’s Yeast, which is a by-product of the brewing industry! (MANY health food store employees have tried to sell me this in the past so be vigilant!)
  • It is affectionately called “Nooch” by those who love it (If you’ve ever seen that term, now you know what it is!)
  • Most good health food stores will stock nutritional yeast
  • It can be easily ordered online via Amazon
  • In Australia, I order from Aussie Health Products (sold as “savoury yeast flakes”)


  • This is a great alternative for vegans and those who are lactose-intolerant or trying to cut-back on dairy and/or fat
  • Because of it’s strong smell/taste, some people find Nooch off-putting the first time they eat it (especially if they still eat dairy cheese and/or recently went vegan)
  • In my experience, the longer you’ve been vegan, the more likely you are to think that this tastes like “real cheese”
  • When trying nutritional yeast for the first time, start by sprinkling it on pasta (to mimic Parmesan) or using a tablespoon or two in other savory dishes, such as those mentioned above
  • Once you’re ready to go “Full-Nooch”, I encourage you to try making the Best Ever Mac & Cheese I’ve ever had – it’s life-changing!

PS. According to Wikipedia, some movie theaters offer nutritional yeast as a popcorn condiment. Have you ever seen this? I would die and go to heaven if I ever saw that!!
