What is a Volcano Roll?

A Volcano Roll is an inside-out sushi roll typically filled with crab, cucumber, avocado, or shrimp, then topped with a creamy seafood mixture made from imitation crab, shrimp, scallops, or spicy tuna blended with Japanese mayonnaise and spicy sauces. The topping is briefly baked or torched until warm and lightly browned, creating the signature "volcanic" appearance.

Unlike traditional sushi, the Volcano Roll is a modern creation that combines Japanese ingredients with bold fusion flavors.

Preparation Time

  • Prep Time: 30 minutes
  • Cook Time: 8 minutes
  • Total Time: 38 minutes

Servings: 4 rolls (32 pieces)

Step 1: Prepare the Sushi Rice

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

Allow it to cool to room temperature before assembling the rolls.

Step 2: Make the Volcano Topping

In a bowl, combine:

  • Chopped shrimp
  • Chopped imitation crab
  • Japanese mayonnaise
  • Sriracha
  • Chili garlic sauce
  • Soy sauce
  • Sesame oil

Mix until creamy and evenly combined.

Step 3: Assemble the Sushi Roll

Place a sheet of nori on a bamboo 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 cucumber, avocado, and crab across the center.

Roll tightly using the bamboo mat.

Repeat with the remaining ingredients.

Step 4: Slice the Roll

Using a sharp knife moistened with water, cut each roll into 8 equal pieces.

Arrange the pieces on an oven-safe tray.

Step 5: Add the Volcano Topping

Spoon the seafood mixture generously over each sushi piece.

Create small rounded mounds to give the roll its signature volcano-like appearance.

Step 6: Bake or Torch

Bake in a preheated oven at 220°C (425°F) for 6–8 minutes, or until the topping is hot and lightly browned.

Alternatively, use a kitchen torch to lightly caramelize the topping for a restaurant-style finish.

Tips for Perfect Volcano Rolls

  • Use freshly cooked sushi rice that has cooled completely.
  • Wet your hands when handling sushi rice to prevent sticking.
