Nutritional Yeast

Nutrition

Nutritional yeast contains about 50 grams of protein per 100 grams, and most commercial products are fortified with additional vitamin B12. That matters a great deal for vegans, since B12 naturally occurs mainly in animal foods — nutritional yeast is one of the few reliable plant-based sources.

How to Choose

Check that the product is labeled as fortified with vitamin B12, since not every brand adds it — this is especially worth confirming for anyone eating fully vegan. Look for a pale yellow color, an even flake or powder texture, and no clumping or mold.

Cooking

Nutritional yeast has a naturally cheesy, savory flavor straight out of the jar — sprinkle it over popcorn, pasta, or roasted vegetables for an instant flavor boost. It also blends into cashew sauce to make vegan cheese sauce, or gets stirred into soups for extra depth. It's an endlessly versatile staple in any vegetarian kitchen.

Storage

Keep nutritional yeast sealed in a cool, dry place away from moisture to prevent clumping — it generally keeps for 1–2 years. Once opened, sealing and refrigerating it helps preserve both flavor and vitamin potency.

Tips

Nutritional yeast is entirely different from the active yeast used in brewing or baking — it's been deactivated and has no leavening power, so don't mix the two up or your recipe won't turn out as expected. Mixing nutritional yeast with cashew powder, garlic powder, and salt in the right proportions makes a simple vegan parmesan substitute — delicious sprinkled over pasta or salad.
