The sauce is deliciously caramelised with a savoury-sweet flavour profile that works with more than just eel. It’s made from just a few simple ingredients: soy sauce, mirin, sugar, and sake. And the steps are even more simple than the ingredients so you can create your own homemade eel sauce in no time. Take all your dishes to the next level with this quick and easy unagi sauce recipe!

What is Unagi Sauce?

Unagi sauce, called unagi no tare in Japanese, is a sweet and savoury condiment that adds a finger-licking good coating of flavour to any dish. The sauce isn’t actually made from eel but is named after the food it’s most associated to – the very popular ‘unagi don‘. This dish features a bowl of rice topped with grilled eel coated in this delicious sauce, hence the name. The sauce itself is made from 4 simple ingredients: soy sauce, mirin, sugar, and sake. These are staples in Japanese cooking and are the same used to make teriyaki, however the difference lies in the consistency. It has a thick and viscous consistency making it easy to glaze over grilled eel and other meats and to use on sushi rolls and as a dipping sauce. It’s delicious and popular and luckily making your own homemade unagi sauce is very easy.

Unagi Sauce Ingredients

This delicious sauce is made with the same few key ingredients as teriyaki sauce that give it its distinctive taste. 

Soy sauce

This is often the base of sauces. Soy sauce packs a punch of umami flavor and gives the dish an extra burst of saltiness. Low sodium and gluten-free options are available nowadays for anyone with dietary needs. If you can’t find gluten-free soy sauce then you can substitute it with tamari which contains no wheat but is still made from soybeans. 

Sugar

This balances out the salty flavours of soy sauce and adds a complimentary sweetness to unagi sauce.  It makes the sauce caramelized when cooked, creating a sticky glaze perfect for grilled eel. The sugar can be either granulated or brown depending on personal preference. 

Sake

Another essential ingredient in unagi sauce as it provides depth and complexity to the overall flavour profile and enhances the umami flavours . Sake is a Japanese rice wine that’s often used in cooking due to its subtle sweetness and mild acidity. 

Mirin 

This rounds out this tasty sauce concoction with its sweet aroma and syrupy texture. Mirin is similar to sake but sweeter as it is translated to sweet rice wine in English, making it an excellent choice for marinades and sauces like Unagi Sauce. Its natural sugars caramelise during cooking to create a glossy finish on top of grilled eel. There are two types of Mirin, I recommend to use Hon Mirin. Read more about mirin here.

These four ingredients – soy sauce, sugar, sake and mirin – work together harmoniously to create this beloved Japanese sauce. With their unique combination of flavors ranging from umami-rich soy sauce to sweet mirin syrupiness, they are what make this condiment so special. The golden ratio is 1:1 of everything. If you use 1 cup soy sauce, then use 1 cup each of mirin, sake, and sugar too. These four ingredients are Japanese pantry staple condiments, but if you don’t have any of those, see this post for substitution.

Tips for Making Unagi Sauce

  • You can adjust the sweetness of your unagi sauce by adding more or less sugar.
  • Simmer the mixture carefully over low heat to reduce, as sugar and soy sauce burns easily.

Unagi sauce can be used as a dipping sauce for sushi rolls, sashimi, tempura, and other dishes. Simply pour some into a small dish and dip away!

Unagi sauce makes an excellent marinade for grilled meats like chicken and beef. Brush the meat with the sauce before grilling or use it as a glaze during cooking. 

Drizzle over rice bowls and sushi

If you’re making rice bowls with veggies, meat or seafood then drizzling some unagi sauce on top makes them more flavorful and delicious. Unagi sauce drizzled over unagi sushi is a match made in culinary heaven! It perfectly complements the rich, smoky flavor of grilled freshwater eel and creates a mouthwatering combination of flavors and textures.

Incorporate into stir-frys:

Add the sauce while preparing stir-fry meals such as noodles or vegetable stir fry to enhance the overall taste of the dish. 

Try it with French fries:

Believe me when I say that unagi goes well with french fries too! Just simply try dipping them in unagi sauce instead of ketchup next time.
