Surprisingly, it wasn’t just the sushi; even my kids couldn’t resist asking for more of the sauce with their meals. 

If you aim to infuse a rich, slightly sweet, and savory kick into your dishes, the best way is by introducing eel sauce to your kitchen. Ready to transform your meals? Here’s how this magical sauce can be the answer.

What Is Eel Sauce Recipe?

Eel sauce, often called “unagi sauce” or “kabayaki sauce,” is a staple condiment in Japanese cuisine. It’s important to note that despite its name, eel sauce doesn’t contain eel.

Instead, it’s a sweet and savory reduction made primarily from soy sauce, sugar, and mirin (a rice wine). 

This dark, glossy sauce is commonly drizzled over grilled eel dishes, sushi rolls, and other Japanese delicacies.

With its rich, deep flavor profile, it’s one of the simplest ways to add a touch of gourmet elegance to various dishes.

History Of Eel Sauce Recipe

Eel sauce, or “unagi sauce,” has deep roots in Japanese culinary tradition. While the exact origins are somewhat shrouded in time, the sauce is intrinsically linked to kabayaki, a method of preparing eel where it’s split, deboned, skewered, and grilled, often over charcoal.

This preparation dates back to the Edo period (17th to 19th century). The sauce itself was developed as a perfect complement to eel’s rich, fatty texture. Over time, the distinct flavor of this sauce became popular beyond just eel dishes.

Though it’s hard to pinpoint a single inventor, the culinary artisans of Edo-era Japan deserve credit for its creation.

Eel Sauce Recipe

Ingredients List

Soy Sauce1/2 cup
White Sugar1/2 cup
Mirin (Japanese sweet wine)1/2 cup

Ingredient Tips 

  • Soy Sauce Choice: Opt for a high-quality, traditionally brewed soy sauce. It imparts a deeper, richer flavor.
  • Sugar Substitutes: If you want a healthier version, consider using honey or agave nectar instead of white sugar. Adjust to taste.
  • Mirin Authenticity: Ensure you’re using authentic mirin, not just a “mirin-like” seasoning. Genuine mirin brings a unique sweetness and depth.
  • Storage: Always store soy sauce and mirin in a cool, dark place to retain their flavors.
  • Consistency: Slow reduction is the best way to achieve a thick eel sauce. Take time to simmer the mixture until it reaches the desired thickness.
  • Taste Test: As ingredients vary in flavor intensity, always taste and adjust the sweetness or saltiness as needed.
  • Freshness: Be aware of the expiry dates, especially for mirin, to ensure you use fresh ingredients for the best outcome.

What Are The Variations Of Eel Sauce Recipe? 

With its foundational ingredients, Eel sauce invites various adaptations to cater to diverse tastes.

Here are some variations:

  • Spiced Version: Introduce a pinch of chili flakes or a splash of sesame oil for an Asian kick.
  • Citrus Twist: A bit of lemon or orange zest can brighten the sauce and add a fresh note.
  • Ginger Infused: Grate a small piece of fresh ginger into the sauce for an aromatic warmth.
  • Reduced sugar: Consider using brown sugar or molasses for a deeper, caramelized flavor while reducing the quantity.
  • Garlic Punch: A clove of minced garlic can give an added layer of flavor.
  • Vegan Adaptation: Replace traditional soy sauce with a vegan-friendly version.
  • Thick and Syrupy: Increase the simmering time for a more robust, sticky sauce suitable for glazes.

Recipe Directions

Cooking Method

  • Combine the soy sauce, sugar, and mirin in a small saucepan.
  • Place the saucepan over medium heat, stirring occasionally to dissolve the sugar.
  • Allow the mixture to come to a slight boil, and then reduce the heat to low.
  • Continue to cook, stirring occasionally, until the liquid has reduced to about 3/4 cup. This may take around 20-25 minutes.
  • Once reduced, remove the saucepan from heat and allow the sauce to cool for about 10 minutes. As it cools, it will thicken slightly.

Ferment Method

  • Eel sauce does not traditionally involve fermentation. However, remember that some of its ingredients, like soy sauce, are fermented.

Scaling The Eel Sauce Recipe 


  • If you’re serving a larger crowd or want extra for future use, simply double the ingredients. Use 1 cup each of soy sauce, white sugar, and mirin. Adjust the cooking time slightly, as a larger volume may take longer to reduce.


  • For a smaller batch, halve the quantities. Use 1/4 cup each of soy sauce, sugar, and mirin. The reduction time on the stove might be slightly shorter due to the lesser volume.

Yes, eel sauce can be stored and preserved for future use. After cooking and cooling, transfer the sauce to an airtight container or a glass jar with a tight-fitting lid.

Store it in the refrigerator to maintain its freshness and flavor. The shelf life of homemade eel sauce in the refrigerator is typically 2 to 3 weeks

However, it’s important to always check for any signs of spoilage, like an off smell or mold. Consider adding a small amount of a natural preservative like citric acid for a longer shelf life.

However, this might slightly alter the taste. Always use a clean utensil for serving to prevent contamination.

What Are The Substitutes For Eel Sauce?

If you find yourself without eel sauce, several alternatives can come to your rescue:

  • Teriyaki Sauce: While it has a similar sweet and savory profile, teriyaki is a bit thinner but can be reduced for a closer consistency.

  • Sweet Soy Sauce (Kecap Manis): An Indonesian sauce that’s both sweet and thick but lacks the complexity of mirin.
  • DIY Mix: Combine soy sauce, brown sugar, and a splash of cooking wine or sherry for a makeshift version.
Eel Sauce Recipe

How To Adjust The Consistency Of The Sauce? 

Adjusting the consistency of eel sauce can be achieved through simple cooking techniques:

  • To Thicken: Simmer the sauce over low heat for a longer duration, allowing it to reduce further. The sauce will become more concentrated and syrupy as the water content evaporates.
  • To Thin: Add a small amount of water, broth, or more mirin to the sauce and stir well. Heat briefly to ensure the ingredients integrate seamlessly.
  • Cornstarch Slurry: For a quicker thickening method, mix a teaspoon of cornstarch with a little water to create a slurry. Add this to the simmering sauce, stirring constantly until it reaches the desired thickness.
  • Straining: If your sauce has lumps or is too thick, consider straining it through a fine sieve for a smoother texture.

Should We Serve The Sauce Cold Or Warm? 

The serving temperature of eel sauce largely depends on the dish it’s accompanying:

  • With Sushi: Typically served at room temperature or slightly chilled. Cold sauce can complement sushi’s fresh, delicate flavors without overpowering them.
  • As a Glaze: It’s best used warm. A warm sauce ensures even application and better absorption when glazing grilled meats or vegetables.
  • Dipping Sauce: Room temperature is ideal for tempura or fried foods, though some may prefer slightly warmed.
  • Marinade: Room temperature or cold works best, ensuring meats or vegetables marinate uniformly.

Nutrition Table

What Are The Common Mistakes While Making This Sauce?

While making eel sauce is relatively straightforward, there are some common pitfalls to be aware of:

  • Over-reducing: Cooking the sauce for too long can result in an overly thick and sticky consistency. It can also lead to a burnt taste.

  • Substituting Ingredients Improperly: While there are substitutes for mirin, like rice vinegar, incorrect proportions can alter the sauce’s flavor profile.
  • Using Low-Quality Ingredients: The flavor depth of the sauce largely depends on the quality of the ingredients. Opting for low-quality soy sauce or mirin can affect the result.
  • Not Tasting as You Go: Adjusting sweetness or saltiness is easier when you taste the sauce during the cooking process rather than after it’s done.
  • Improper Storage: Storing the sauce while it’s still hot or not using an airtight container can reduce its shelf life.
  • Skipping Straining: If the sauce has lumps or inconsistencies, straining it can ensure a smoother texture.
