If you like Japanese yakisoba noodles, then you’ll love my easy recipe for Homemade Yakisoba Sauce! It’s so quick to whip up with five common ingredients from the pantry.
You are probably familiar with the yakisoba sauce found a Japanese or Asian grocery store. My favorite is made by the famous Otafuku brand, so I made my Homemade Yakisoka Sauce recipe to copy its taste. Let me show you how easy it is to make!

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.

Yakisoba Sauce Ingredients
You’ll need just 5 simple ingredients from your kitchen pantry for this recipe:
- Worcestershire sauce — use vegan Worcestershire sauce for vegan/vegetarian
