Unagi Sushi Rolls are filled with bbq eel, crunchy cucumber, then rolled in nori seaweed sheet and sushi rice! I like to drizzle it with delicious unagi sauce for an extra flavor. This eel sushi is a popular Japanese sushi item and one of my favorite sushi rolls. In this homemade recipe, you will learn how to make sushi rice, how to prepare unagi, and how to roll the sushi!
What is Unagi Sushi?
Unagi Sushi is a type of Maki sushi (rolled sushi) made by rolling ingredients in nori seaweed sheet and seasoned rice. The key ingredient is unagi or freshwater eel, which is known for the bold, rich, naturally sweet flavor, and soft texture. It’s a popular ingredient in many Japanese dishes.
For this recipe I made it into an inside-out roll where the rice is on the outside and the nori is on the inside, wrapping the filling.
Ingredients You’ll Need
- Unagi: Traditional unagi sushi contains grilled BBQ unagi (eel), a cooked fish flavored with teriyaki sauce or unagi sauce. It’s available in the frozen section at local Japanese grocery stores, or you can order canned unagi online from Amazon.
- Cucumber or Avocado: You can add cucumber strips or avocado slices to your roll. I also added some green onions for extra flavor.
- Sushi Rice: Use Japanese short-grain rice for the best result.
- Sushi Vinegar: For seasoning the rice and adding more flavor to the dish. If you don’t have sushi vinegar, you can mix rice vinegar, sugar, and salt as a replacement.
- Nori Seaweed Sheet: Look for seaweed sheets with a black color with a slightly green hue.
- Unagi Sauce: It’s optional, but it’ll take your unagi roll to the next level. Buy it at a Japanese grocery store, or order it online.
- Sesame Seeds: You can use black, white, or a combination of white and black sesame seeds. I recommend toasting them in a frying pan for 5 minutes, and it’ll add a wonderful nutty flavor and aroma to your rolls.
You’ll also need a sushi rolling bamboo mat for easy rolling.
How to make Unagi Eel Sushi
Cook Sushi rice
A great sushi roll starts with good sushi rice, which will stay fluffy even after it’s tightly rolled. So use high-quality short-grain rice for sushi rolls. I recommend using less water than cooking regular rice. The best water to rice ratio is 1:1 (or use 1.2:1 if you prefer softer rice). Once cooked, transfer the hot rice to a large bowl and let it cool down slightly. When it’s still very warm, stir in the sushi vinegar (the mixture of rice vinegar, sugar, and salt).
Take the unagi from the package and bake at 360F for 10-12 minutes or according to the package instruction. Then cut it into 1/2 inch strips.
Make the Unagi Roll
For this recipe, the rice is on the outside, covering the nori and fillings.
1. You’ll need half of a nori sheet for one roll. So cut the sheet into two halves with kitchen scissors.
2. Lay out your bamboo mat with a piece of plastic wrap on top. Then place the nori sheet on top of the bamboo shining side facing down.
3. Evenly spread rice (about 3/4 cup) over nori. And sprinkle sesame seeds.
4. Then flip the sheet and add unagi slices and cucumber, green onions (or any other fillings) to the middle of the nori sheet.
5. Place the thumbs underneath the bamboo mat and lift the edge up and over the filling. Roll the bamboo mat away from you and press the rice and filling together. Keep rolling until the ends meet.
6. Cut the roll into 8 pieces. Drizzle unagi sauce on top of the sushi for some extra delicious flavor. Serve and enjoy immediately.
- To prevent the rice from sticking to your hands: Before handling rice, you can dip your hands in Tezu water, which is a hand dipping liquid made with 1/4 cup water and 2 teaspoons of rice vinegar.
- To prevent sushi rolls from falling apart: You’ll need to squeeze the roll gently while rolling. Once you finish, you can place the bamboo mat over the sushi roll and gently squeeze the roll again.
Also called eel sauce or kabayaki, unagi sauce is a sweet and salty sauce that’s often used to drizzle grilled chicken or fish in Japanese cuisine. You can buy them at local Japanese grocery stores or order online.
To make homemade unagi sauce, simply add 1/4 cup mirin, 1/4 cup soy sauce, 2 tablespoons sugar, and 1 ½ tablespoons sake to a saucepan. Bring to a boil and simmer for about 10 minutes.
Is Unagi Cooked in Sushi?
Yes, in this recipe we used cooked unagi. If you use the frozen unagi from the package, you’ll need to bake it at 360F for 10-12 minutes or according to the package instruction. Then cut it into 1/2-inch strips. You can also use canned unagi.
How to Select Nori Sheets?
Best nori sheets have a black color with a slightly green hue. They should have the same thickness without any holes. The fresh ones are crisp and easy to break when folding in half.
