How It Actually Works
You blend raw cashews with nutritional yeast, garlic powder, and salt until you get something that resembles coarse sand. That's the foundation. The rest is just tweaking ratios until the salt and umami feel right for whatever you're putting it on. I've made this probably two dozen times over the years, and every batch lands somewhere between fine and slightly too salty, depending on how careful I am with measurements. The real trick isn't the recipe, which is straightforward enough. It's the equipment. A standard blender leaves you with uneven chunks of nut and powder. You want a food processor or a decent high-powered blender that can actually pulverize cashews into a fine meal before the other ingredients go in. If you're using a basic blender, pulse first, scrape down the sides, then pulse again. Total time is about two minutes.
Vegan Parmesan Cheese Recipe
Here's the baseline ratio I use: 1 cup raw cashews
3 tablespoons nutritional yeast
½ teaspoon garlic powder
¼ teaspoon fine sea salt
A pinch of onion powder if you want extra depth Pulse the cashews first until they reach a coarse meal, about 30 seconds. Add the rest and pulse another 15 to 20 seconds. The mixture should look like freshly grated parmesan, not a paste. If it starts clumping together, you've blended too long and the natural oils are coming out. Stop immediately.
This keeps in the fridge for roughly two weeks in an airtight container. Some people freeze it for longer, but I haven't tested that personally and wouldn't recommend it without knowing how the texture changes after thawing.

Why It Works and Where It Fails
Cashews provide the fat content that mimics dairy cheese mouthfeel. Nutritional yeast brings the umami flavor. Garlic and onion powder add savory complexity. Salt controls both taste and moisture — which sounds obvious but matters more than people realize. I learned this after my first batch went bad. I was short on salt and just dumped in a pinch instead of measuring. Two weeks later, the mixture had developed a sour smell. I tossed it. Since then I weigh everything. Not because precision is fun, but because under-salted batches spoil faster. Salt reduces water activity, and that's the whole reason this stays edible for more than a few days. The most common mistake is using salted cashews and then adding the full measured salt on top. The result is inedible. If you're using salted cashews, cut the added salt in half or skip it entirely. Taste the ground nut meal before adding anything else. It tells you immediately whether you're on track.
Things Beginners Miss
Most people toast their nuts first. I don't. Raw cashews give a milder, more neutral base that lets the nutritional yeast carry the flavor. Toasted cashews introduce a bitter, roasted note that fights with the umami. If you do toast them, three minutes at 300°F maximum. Longer and the oils begin to oxidize, which shortens shelf life and changes the taste in a way most people don't notice until it's already in the jar. Another detail nobody talks about: nutritional yeast brand matters. Some are finer and clump instantly. Others are coarser and blend unevenly. If yours tends to cake, pulse it with the cashews separately first, then add the spices. This distributes everything more evenly and prevents those weird pockets of pure yeast powder that hit your tongue all at once. Also, this does not melt. Don't expect it to brown on pizza or form a crust. It stays granular under heat. It's a finishing topping, meant for pasta, risotto, roasted vegetables — anywhere residual warmth is enough to release the aroma without cooking it further. If you need something that melts, a commercial vegan cheese blend or a cashew cream sauce is what you should make instead.
Practical Numbers
Yield is about ½ cup, which covers 4 to 6 servings as a pasta garnish. One batch lasts me about a week and a half with regular use. The entire process takes roughly 3 minutes from start to finish if your processor is any decent quality. Storage is the only real variable. A glass jar works better than plastic because cashew oils can degrade certain plastics over time and leave a slight taste. I keep mine in a small mason jar. Fridge or counter both work, though refrigeration firms up the oils slightly and makes the texture a bit grainier. Room temperature keeps it loose and free-flowing. Just keep it out of direct heat and light.
