What is a Caterpillar Roll?

A Caterpillar Roll is an inside-out sushi roll (uramaki) typically filled with grilled freshwater eel (unagi), cucumber, and sometimes avocado. Thin slices of ripe avocado are arranged over the top of the roll to resemble the back of a caterpillar. The roll is often finished with a drizzle of sweet unagi sauce, sesame seeds, and occasionally tobiko for decoration.

  • Total Time: 40 minutes

Servings: 4 rolls (32 pieces)

Step 1: Prepare the Sushi Rice

Season the cooked sushi rice with rice vinegar, sugar, and salt.

Allow the rice to cool to room temperature.

Step 2: Prepare the Fillings

Warm the grilled unagi according to the package instructions or briefly under a broiler.

Slice the cucumber into thin strips.

Peel the avocados and cut one avocado into thin slices for the topping. Slice the second avocado into strips if you'd like additional filling.

Step 3: Assemble the Roll

Place a sheet of nori on a bamboo sushi mat covered with plastic wrap.

Spread an even layer of sushi rice over the nori.

Flip the nori so the rice faces downward.

Arrange the grilled unagi and cucumber across the center. Add avocado strips if desired.

Roll tightly using the bamboo mat.

Step 4: Add the Avocado Topping

Arrange the thin avocado slices neatly across the top of each roll, slightly overlapping to create the caterpillar effect.

Cover with plastic wrap and gently press with the bamboo mat to secure the avocado.

Step 5: Slice the Roll

Using a sharp knife dipped in water, cut each roll into 8 even pieces.

Wipe the knife clean between cuts to keep the slices neat.

Drizzle generously with unagi sauce.

Tips for Perfect Caterpillar Rolls

Frequently Asked Questions

Why is it called a Caterpillar Roll?

The roll gets its name from the overlapping avocado slices placed on top, which resemble the segmented body of a green caterpillar.

Is the eel cooked?

Yes. Traditional unagi is fully cooked and glazed before being used in sushi, making Caterpillar Rolls a great option for those who prefer cooked seafood.

Can I use another fish instead of eel?

Yes. Cooked shrimp, crab, smoked salmon, or grilled salmon are delicious alternatives, though the classic version uses grilled eel.

What is unagi sauce?

Unagi sauce is a sweet and savory glaze made with soy sauce, mirin, sugar, and sake. It complements grilled eel and many sushi rolls.

Can I make Caterpillar Rolls ahead of time?

You can prepare them a few hours in advance, but for the freshest flavor and best texture, they should be assembled and served the same day.
