Ingredients You’ll Need
The beauty of this Eel Sauce (Unagi Sauce) Recipe lies in its simplicity and the thoughtful balance of its ingredients. Each one contributes uniquely to the sauce’s luscious texture, rich taste, and beautiful sheen, making it a breeze to whip up something extraordinary.
- Granulated sugar: Adds the perfect sweetness that balances the salty and tangy components of the sauce.
- Soy sauce: Brings that deep umami flavor and saltiness that is essential to authentic eel sauce.
- Mirin: A sweet Japanese rice wine that adds a mild tang and glossy finish to the sauce.
How to Make Eel Sauce (Unagi Sauce) Recipe
Step 1: Combine Your Ingredients
Start by whisking together ½ cup granulated sugar, ½ cup soy sauce, and ½ cup Mirin in a small saucepan. Blending these at room temperature ensures the sugar dissolves evenly and sets the stage for a smooth, cohesive sauce.
Step 2: Simmer and Thicken
Place the saucepan over medium heat and let the mixture gently simmer. Stir occasionally so the sugar doesn’t stick or burn. This step requires patience because the sauce will gradually thicken and reduce to about ¾ cup, concentrating those vibrant flavors into a luscious glaze.
Step 3: Cool Before Using
Once thickened, remove the sauce from heat and allow it to cool completely. The texture will become similar to honey when it cools down, making it easy to drizzle or brush onto your favorite dishes. It’s now ready to enhance your culinary creations or store for later delight.
How to Serve Eel Sauce (Unagi Sauce) Recipe

Garnishes
To really make your dish sing, consider pairing the eel sauce with toasted sesame seeds, finely sliced green onions, or a sprinkle of crushed nori. These garnishes add crunch, color, and an extra dimension of flavor that creates a perfectly balanced bite.
Side Dishes
This sauce isn’t just for eel or unagi rolls. It complements steamed white rice, grilled vegetables, or even tempura with its rich, sweet-savory profile. Serving alongside lightly pickled ginger can also brighten your palate between bites.
Creative Ways to Present
Drizzle eel sauce artistically over sushi platters, poke bowls, or roasted meats. You can even use it as a dipping sauce or glaze for grilled chicken skewers or roasted eggplant to add a delightful Asian-inspired twist to your meals.
Make Ahead and Storage
Storing Leftovers
After preparing your Eel Sauce (Unagi Sauce) Recipe, store any leftovers in an airtight container in the refrigerator. It will keep well for up to two weeks, allowing you to conveniently add that rich, sweet-savory flavor any time you want.
Freezing
While you can freeze eel sauce, it’s best enjoyed fresh or refrigerated. If you do choose to freeze it, use a freezer-safe container and thaw slowly in the refrigerator. Freezing may slightly alter the texture but the flavor will remain intact.
Reheating
When you want to use stored eel sauce, gently reheat it on the stove over low heat or briefly in the microwave until it reaches your desired consistency. Stir well to restore its smooth texture and glossy appearance before serving.
FAQs
Can I use a substitute for Mirin in this eel sauce?
Yes, if you don’t have Mirin, you can substitute with a combination of dry white wine and a pinch of sugar to mimic the sweetness and acidity, though the flavor won’t be exactly the same as traditional Mirin.
Is this sauce only for eel?
Not at all! While traditionally served with grilled eel, this versatile sauce pairs beautifully with many dishes, such as sushi, grilled vegetables, chicken, and even drizzled over rice bowls or noodles.
How thick should the eel sauce be?
The ideal consistency is thick enough to coat the back of a spoon, similar to honey once cooled. This allows it to cling nicely to your food without running off too quickly.
Can I make this sauce vegan?
Absolutely! Just ensure you use a vegan-friendly soy sauce. Since this recipe contains no animal products, it’s easily adaptable to vegan and vegetarian diets.
Why does the sauce need to be cooled before using?
Cooling thickens the sauce further and lets the flavors meld together. It also makes it easier to handle and apply as a glaze or drizzle without being too runny.
