Nutritional Yeast

Modern product, popularized primarily in vegan and vegetarian cooking in the United States and Europe from the mid-20th century onward

Deactivated yeast flakes or powder, similar in raw material to the yeast extract used in Vegemite and Marmite but processed differently (dried into flakes rather than concentrated into a paste), prized for a naturally savory, cheese-like flavor.

Flavor Profile

Savory and nutty with a distinct cheese-like quality (often described as similar to Parmesan) despite containing no dairy.

Culinary Uses

Sprinkled over popcorn, pasta, and vegetables as a dairy-free flavor enhancer and cheese substitute; stirred into vegan sauces for body and umami.

Regional Variations

Fortified versions (with added B12 and other vitamins) are common and specifically marketed toward vegans who may lack other dietary B12 sources.

Storage

Keeps many months to a year in a sealed, dry container at room temperature.

Related in raw material to Vegemite and Marmite but processed and marketed for an entirely different purpose and audience.
