How to Make Spicy Kani Roll — Japanese Crab Sushi

This spicy kani roll, also known as a spicy crab roll, is an easy and flavorful kani sushi recipe. Filled with a creamy, spicy kani salad and a drizzle of spicy mayo, it delivers the familiar sushi taste with a pleasant kick.

This recipe uses cooked imitation crab (surimi), making it a great option for people who prefer not to eat raw fish.

In Japanese, “kani” means crab. A spicy kani roll is the same concept you’ll find in many American sushi restaurants under the name “spicy crab roll.” Kani sushi refers broadly to any sushi that uses crab, either real or imitation, and because the crab used for this roll is cooked, it’s approachable for cooks of all levels.

The core of this roll is a simple kani salad: shredded imitation crab mixed with mayonnaise and sriracha to create spicy mayo. You can customize the finished roll by adding a drizzle of sweet-spicy sauce or a sprinkle of sesame for texture. If you prefer a crunchier texture, top the roll with tempura flakes or panko for a crunchy crab roll variation.

Why this kani sushi roll is the best

• This recipe uses imitation crab (kanikama or surimi), which is already cooked, so it’s a safer choice for those avoiding raw fish.
• You can make extra spicy kani salad to serve as a side or to scoop over sliced cucumbers when you want a lower-carb option.
• It’s easy to transform into a crunchy roll by adding tempura crunch or toasted panko on top.

Instructions to make spicy kani roll (spicy crab roll)

How to make the sushi rice

1. Rinse the rice in a fine-mesh strainer until the water runs clear to remove excess starch. Shake off excess water.
2. Combine the rinsed rice, water, and 1 tsp salt in a rice cooker or instant pot. Cook according to your device’s instructions (for an Instant Pot: high pressure 6 minutes, then natural release).
3. Transfer the cooked rice to a wide bowl. Sprinkle the seasoned rice vinegar evenly over the rice.
4. Using a wide, flat spatula, gently fold the vinegar into the rice without smashing the grains. Allow the rice to cool to near room temperature before rolling.

Make the spicy kani (crab) mix

1. Shred the imitation crab or flake canned/fresh crab if using real crab.
2. In a small bowl, combine the crab with mayonnaise and sriracha to taste. Adjust the ratio to make it creamier or spicier as you prefer.

How to roll the spicy kani roll

1. Cover a bamboo rolling mat with plastic wrap to keep it clean and prevent sticking. Place a nori sheet, shiny side down, on the mat.
2. Wet your hands with water to prevent rice from sticking, then spread about 1 cup of sushi rice evenly across the nori, leaving a ½–1 inch strip at the far edge free of rice.
3. Flip the nori over so the rice is facing down and the nori side is up. Place a line of the spicy kani mixture across the center, about 1 inch from the bottom edge of the nori.
4. Use the bamboo mat to lift the near edge of the nori and fold it over the filling, tucking gently with your fingers. Roll firmly but gently until you form a tight cylinder. Pull the mat back and continue shaping the roll.
5. With a sharp knife dipped in water and wiped clean, slice the roll in half, then cut each half into three equal pieces (or as desired). Wipe the knife between cuts to ensure clean slices.
6. Garnish with a drizzle of spicy mayo, sesame seeds, or a touch of additional sriracha if desired. Serve with pickled ginger and wasabi on the side.

Leftovers and storage: Sushi with mayonnaise-based filling is best eaten fresh. For best quality, eat immediately and avoid long storage.
