What is Yakisoba Sauce?

Yakisoba sauce (焼きそばソース) is a sweet, salty, and savory sauce. Compared to similar brown sauces, such as tonkatsu sauce, it’s less fruity and sweet, with a more prominent soy sauce flavor. It’s also a bit thinner to more easily combine with ingredients like noodles and vegetables when frying in a large skillet or on a griddle.

This condiment is very popular in Japanese cooking! We use it mainly to season Yakisoba, the classic Japanese stir-fried noodle dish and common street food. However, you can use this versatile and delicious sauce to boost the flavor of any stir-fry recipe like chow mein, stir-fried vegetables, and fried rice as well as other fried dishes like okonomiyaki, tonkatsu, and takoyaki.
