It’s a dish made from soybeans that are fermented in a process that uses a bacteria, Bacillus subtilis. The beans are then aged for a week, resulting in a very unique dish. So are you wanting to know what natto tastes like? We’ll take a close look at its flavor, texture, aroma, and much more. Let’s dive in!

What does natto taste like?

Natto has a mild fermented flavor with a slightly bitter, earthy undertone that some describe as similar to aged cheese. However, it is not the flavor that many people find off-putting, it’s the aroma.

Natto has a pungent acrid smell that is similar to old socks or smelly cheese. The bacteria that produce this smell, are similar to those that are used to make many smelly cheeses, which is why their smell is comparable.

If you can’t tolerate the aroma of Munster or bleu cheese then this Japanese dish will cause problems for you.

The texture of natto will also test a newcomer to their limits, thanks to its sticky, gooey nature. If you eat the dish with larger soybeans, they are less sticky and easier to eat. The option that uses crushed soybeans (hikiwari) is a much stickier version with more flavor and an extra powerful aroma.

Locals in Japan usually eat natto for breakfast or lunch, and it is traditionally served with hot rice, vegetables, green onions, and condiments like karashi mustard or soy sauce (tare).
