Ingredients

2 cups sushi rice, cooked and seasoned with rice vinegar, sugar, and salt
4 nori sheets
1 cup imitation crab, shredded
1/2 avocado, sliced thinly
1/4 cup cucumber, julienned
1/4 cup spicy mayo (mayonnaise + sriracha)
1 tbsp sriracha (additional, for drizzle)
1 tsp sesame seeds
2 tbsp tobiko (flying fish roe, optional)
Green onions, finely chopped for garnish

Instructions

Prepare Sushi Rice: Cook sushi rice according to package directions. While still warm, season with 2 tbsp rice vinegar, 1 tbsp sugar, and 1 tsp salt. Gently fold to combine and cool slightly.
Prepare Crab Mixture: In a small bowl, combine shredded imitation crab with 2 tbsp spicy mayo. Mix until fully coated.
Roll Sushi: Place a bamboo sushi mat on a clean surface and cover with plastic wrap. Lay a nori sheet shiny side down. Spread an even layer of sushi rice, leaving the top edge free.
Add Fillings: Layer crab mixture, avocado slices, and cucumber along the bottom third of the nori sheet.
Roll Tight: Using the bamboo mat, carefully roll the sushi from the bottom, pressing gently but firmly. Seal the edge with a little water.
Top Roll: Spread a thin layer of spicy mayo on top. Drizzle with sriracha, sprinkle sesame seeds, and add tobiko if using.
Slice and Serve: Using a sharp, wet knife, cut the roll into 6–8 even pieces. Garnish with chopped green onions. Serve immediately.

Fun Facts & Cultural Context

The spicy crab roll is a Japanese-American sushi creation that became popular in fusion sushi restaurants. Unlike traditional sushi, it’s fully customizable and often baked or topped with creamy sauces to enhance flavor. Spicy mayo, a signature in fusion sushi, combines Japanese mayonnaise with chili sauce to create a bold and creamy topping.

This roll is widely served in sushi restaurants across the U.S. and is known for its vibrant appearance and rich flavor profile. Making it at home allows you to control spice levels and ingredients while enjoying restaurant-style sushi in the comfort of your kitchen.

Variations
