  • It’s super easy to make: All you need is five minutes to mix together the five simple ingredients.
  • It’s flavour-packed: The combination of oyster sauce, soy sauce, ketchup, Worcestershire sauce and sugar creates an umami-packed sauce with a perfect balance of sweet, savoury and umami flavours.

Yakisoba sauce ingredients and substitutes

This yakisoba sauce is an easy-to-make Japanese sauce that is the perfect companion for Japanese stir-fried noodles.

Ingredients for yakisoba sauce in small bowls including oyster sauce, soy sauce, tomato ketchup, and sugar. With a bottle of Lea and Perrins Worcestershire sauce.

It requires just a few ingredients:

  • Oyster sauce: Oyster sauce adds a sweet and savoury flavour to this yakisoba sauce. But if you are allergic or prefer a plant-based sauce, you can use vegan stir-fry sauce instead.
  • Soy sauce: Use all-purpose or light soy sauce. Dark soy sauce is too intense for this recipe.
  • Ketchup: Use your favourite tomato ketchup for a flavourful yakisoba sauce. If your tomato sauce is not very acidic, you can add a small splash of rice vinegar to balance the sauce.
  • Sugar: I use white sugar, but you can use brown sugar or your preserved sweetener.
  • Worcestershire sauce: I use Lea & Perrins, but you can use any brand you have.

Store-bought oyster sauce, soy sauce and Worcestershire sauce typically contain gluten. You can swap the combination for a shop-bought gluten-free stir-fry sauce. But you’ll need to adjust the sweetness and acidity of tomato ketchup to taste.

How to make yakisoba sauce

This simple sauce is similar to classic Otafuku Yakisoba sauce, a popular Japanese stir-fry sauce found in many Asian grocery stores.

But once you see how easy it is to make homemade yakisoba sauce, you’ll never buy store-bought sauce again!

Step 1: Gather your ingredients. You will need:

  • three tablespoons of oyster sauce or vegan stir-fry sauce,
  • one and a half tablespoons of soy sauce,
  • two tablespoons of ketchup,
  • one and a half tablespoons of sugar and
  • four tablespoons of Worcestershire sauce.

This makes about a ¾ cup of sauce. You can easily double the recipe if you need more sauce.

Step 2: Combine the ingredients. In a small bowl, add the oyster sauce, soy sauce, ketchup and sugar. Whisk together until the sauce is well combined and sugar has dissolved.

You can also microwave the mixture in a microwavable bowl for 20 seconds to help the sugar dissolve.

Step 3: Adjust the seasoning. Stir in the Worcestershire sauce. Taste and season with more sugar for a sweeter sauce or a pinch of salt for a savoury boost – until the sauce is balanced to your liking.

It should be punchy and bold in flavour because you will only add 2 tablespoons per portion of noodles.

The sauce works great with yakisoba noodles – the traditional Japanese choice. But it is delicious with all noodle dishes.

Try it with ramen noodles, udon noodles, egg noodles or any other stir-fried noodle dish.

Storage: Refrigerate leftover yakisoba sauce in an airtight container for up to two weeks.
