Sweet, savory, and full of flavor, this delicious Homemade Eel Sauce recipe is the dream sauce for Japanese broiled eel fillets and BBQ dishes. You only need four ingredients!
Eel sauce, or unagi no tare (うなぎのたれ), is a thick and sweetened soy sauce. Traditionally, it is used on grilled eel or dishes that feature grilled eel, such as unagi don or unagi sushi, and doesn’t contain eel.

What Is Eel Sauce
What is that caramelized brown sauce with a syrup-like consistency that goes with unagi? Well, the irresistible glossy sauce is Eel Sauce or Unagi Sauce.
Although many commercial sauce brands are available, the best eel sauce is the homemade version.
What Does It Taste Like
It tastes savory-sweet from the sake, soy sauce, mirin, and sugar. Since the ingredients are the same as teriyaki sauce, you might wonder if eel sauce is the same. Yes, both sauces are similar, but you’ll notice the slight differences in the richness and sweetness.

How to Make Eel Sauce
Making homemade unagi sauce is as simple. You only need four ingredients to create a rich, umami-packed sauce.
The Ingredients You’ll Need
- Sake (Japanese Rice Wine) – Adds umami to the sauce (the alcohol will burn off during cooking, so it’s suitable for all ages).
- Mirin (Sweet Rice Wine) – Adds a mild sweetness and luster to the sauce.
- Soy sauce – Use Japanese soy sauce as it tastes different from Chinese, Korean, or Thai. Use Gluten-Free Soy Sauce or Tamari to make a gluten-free sauce.
- Sugar – Besides sweetness, sugar is a thickener, so it’s easy to pour.
Sake, mirin, and soy sauce are essential staples for Japanese cooking, so it’s worth stocking up if you’re thinking of cooking your favorite Japanese recipes.
Note: Authentic unagi sauce does not use rice vinegar as it adds an acidic tang and does not contribute to the integrity of the sauce. Also, don’t add garlic, ginger, or cornstarch to the sauce. It wouldn’t be unagi sauce with all these additions or it’ll overwhelm the unagi.
The Cooking Step
- Combine the mixture in a small saucepan and simmer on medium heat until the sauce caramelizes and thickens to your desired richness.
The great thing about making the sauce instead of buying the bottled variety is you can decide on the balance of sweet and salty. Plus, there are no additives or preservatives.
How To Use Eel Sauce
Aside from unagi dishes, unagi sauce is finger-licking delicious on BBQ. Think grilled fish, pan-fried chicken, tofu, mushrooms, and onigiri rice balls. All you need is a light brush or a drizzle of this sweet-savory sauce to heighten the flavor. In addition, you can use it as a marinade for meats or as a dressing for noodles.

How To Store
Store leftovers in an airtight container or jar in the fridge or freezer for 2-3 months.

Is there a preference for the type of sugar used for this recipe?
Hi Andrea! Thank you so much for trying Nami’s recipe!
Nami uses organic cane sugar (natural blond/tanned color sugar; She gets one from Trader Joe’s), but other sugar would work.
We hope this helps!
Just wish to say your yaki onigiri and unagi sauce recipe maintain Japanese umami flavours. It never ceases to surprise me when gaijin san substitute ingredients and say it is the same. As a gaijin too
it is apparent some readers must not have ‘ lived Japan’ to appreciate the subtleties of its food and umami delights. Your site is perfect Nami san.
Hello there, Daivd! Thank you for reading Nami’s post and for your kind words.
We appreciate your love and support. Happy cooking!☺️
This is basically Teriyaki sauce, There is no eel or fish base in the sauce. I bacally used this recipe but added fish sauce and adjusted the sugar to taste and I used agave nectar instead of sugar. Keep in mind that there is sugar in Mirin and you want a sugar salt balance
Hi William, Thank you for your feedback. Yes. There is no eel in the sauce and uses it for many dishes.
We hope you have a chance to read this recipe post. Nami explains what Eel Sauce is.🙂
As for sweetness, Mirin is our traditional ingredient, and it offers a delicate sweetness and a nice aroma to many Japanese dishes. So most Japanese recipes use Mirin and Sugar to balance the flavor and taste.
Here is a post about Mirin: https://www.justonecookbook.com/mirin/.
We hope this helps!
Ohhh myyyy god… it’s so gooood. Perfect bliss point between salty and sweetness. The taste was so addictive, couldn’t stop eating the sauce on its own haha. Thank you very much for sharing such a great yet simple recipe. It tastes even better than the one from restaurants.
Forgot to mention, I marinaded the sauce and cooked it with salmon. It made my salmon taste so divine.. ❤️😋 just have to find the way to make the skin stays crispy. Any tips? 😊
Hi Aoh! Thank you very much for trying Nami’s recipe and your kind feedback!
We are glad to hear you enjoyed homemade Unagi Sauce!
To make the skin crispy, brush the sauce and put it in the oven for a few minutes, or use a broiler and cook the skin sides until it gets crispy. You can also use Cooking Torch.
