Nutritional yeast, or 'nooch,' is a deactivated yeast with a cheesy, savory flavor. Learn what it is, its benefits, and simple ways to use it in everyday cooking.
Quick Answer
Nutritional yeast is a deactivated yeast with a savory, cheesy flavor, often used as a vegan cheese substitute. You can sprinkle it on popcorn, stir it into sauces, or blend it into dressings for an umami boost.
Why It's Not the Same as Baker's Yeast
Nutritional yeast is different from the active yeast you use for bread. During processing, the yeast is heated and dried, which deactivates it. This means it won't make dough rise, but it also means it's safe to eat in large amounts and adds flavor without fermentation.
Because it's inactive, you can use it as a seasoning rather than a leavening agent. That distinction is key if you're new to nooch and want to avoid confusion in the kitchen.
Fortified vs. Unfortified: A Practical Trade-Off
Fortified nutritional yeast has added vitamins, typically including B vitamins and sometimes B12. Unfortified versions contain only the nutrients naturally present in the yeast. If you're using nooch as a source of B12, you'll want a fortified product, but if you're strictly monitoring your vitamin intake, check the label to see what's added.
For most home cooks, fortified yeast is a convenient way to add a cheesy flavor and some extra nutrients to meals, especially on a plant-based diet.
Nutritional Yeast FAQ
- What does nutritional yeast taste like?
- It has a savory, umami, and slightly cheesy flavor. Some people describe it as nutty or similar to parmesan, which is why it works well as a cheese substitute.
- How do I use nutritional yeast in cooking?
- Sprinkle it over popcorn, pasta, or roasted vegetables; stir it into soups, sauces, or scrambled tofu; or blend it into dressings and dips for a cheesy flavor. Start with a teaspoon and adjust to taste. Try it on popcorn first for an easy introduction.
- Is nutritional yeast the same as brewer's yeast?
- No. They are different strains and have different flavors. Brewer's yeast is often more bitter and is not a direct substitute in recipes that call for nooch. Stick with nutritional yeast for the cheesy flavor you're looking for.
- Can nutritional yeast replace cheese in recipes?
- It can replace the flavor of cheese in sauces, dips, and toppings, but it won't melt or stretch like cheese. For a melty texture, combine it with other ingredients like cashews or potatoes in a sauce. Use it as a flavor booster, not a direct 1:1 cheese swap.
- How should I store nutritional yeast?
- Keep it in an airtight container in a cool, dark place. It can last for months if stored properly. Refrigeration is not required but can extend freshness. Check the expiration date and store away from heat and moisture.
