Ingredients for Spicy Crab Sushi
For the Base
- 4 sheets of nori
- 2 cups sushi rice (about 360 g uncooked)
For the Filling
- 1/2 lb crab meat (preferably imitation crab or kani) (about 225 g)
- 2 tablespoons mayonnaise (≈30 ml)
- 1 tablespoon sriracha (adjust to taste) (≈15 ml)
- 1 cucumber, thinly sliced
- 1 avocado, sliced
To Serve
- Soy sauce for serving
- Pickled ginger for serving
- Wasabi for serving
Ingredient Notes (Substitutions, Healthy Swaps)
- Crab: Imitation crab (kani) works well and is budget-friendly. Use real crab for a sweeter, more delicate flavor (optional).
- Mayonnaise: Use light mayo or a mix of Greek yogurt and mayo for a lower-fat option (optional, will change texture).
- Sriracha: Swap for chili paste or a few drops of hot sauce if you prefer a different heat profile. Reduce by half for mild heat.
- Rice: If you don’t have sushi rice, use short-grain rice. Long-grain rice won’t give the same sticky texture.
- Avocado: For fewer calories, replace avocado with thin slices of mango (optional) for a sweet contrast.
- Gluten-free: Use tamari or gluten-free soy sauce to make the dish gluten-free.
Step-by-Step Instructions
Step 1 – Cook the sushi rice
- Rinse the sushi rice under cold water until the water runs clear.
- Cook according to package instructions (typically on the stove or in a rice cooker).
- Let the rice rest for a few minutes after cooking.
Visual cue: Rice should be glossy and slightly sticky but not mushy.
Step 2 – Make the spicy crab filling
- Flake or chop the crab meat into bite-sized pieces.
- In a bowl, mix crab meat with 2 tablespoons mayonnaise and 1 tablespoon sriracha. Taste and adjust heat.
Visual cue: Filling should be creamy and hold together without being watery.
Step 3 – Prepare the fillings
- Thinly slice the cucumber and slice the avocado just before assembly to avoid browning.
- Keep all fillings near your work area for quick rolling.
Pro cue: If your avocado is too firm, microwave whole avocado for 10–15 seconds to soften slightly, then slice.
Step 4 – Lay out the nori and rice
- Place one sheet of nori shiny side down on a bamboo sushi mat.
- Wet your hands to prevent sticking and grab a handful of sushi rice.
- Spread rice evenly over the nori, leaving about a 1-inch clear strip at the top edge.
Visual cue: Rice layer should be even and thin — about 1/4 inch thick.
Step 5 – Add filling and roll
- Place a line of spicy crab mixture, cucumber slices, and avocado slices along the bottom edge of the rice.
- Using the mat, carefully roll starting from the bottom, pressing gently as you roll.
- Wet the top edge of the nori to seal the roll.
Pro cue: Press gently but firmly to keep the roll tight; too much pressure will squeeze fillings out.
Step 6 – Slice and serve
- Use a sharp knife to slice the roll into bite-sized pieces. Wipe the blade between cuts for clean slices.
- Serve with soy sauce, pickled ginger, and wasabi.
Visual cue: Each piece should hold shape with a visible cross-section of filling and rice.
Pro Tips for Success
- Rinse hands often and keep a small bowl of water beside you to prevent rice sticking when spreading.
- Use a very sharp knife and moisten the blade to slice cleanly without pressing down.
- Chill the roll for 5–10 minutes before slicing to help it hold its shape.
- Slice in a single clean motion — don’t saw back and forth.
- Balance rice amount: too much rice overwhelms the filling; aim for a thin, even layer.
- Make just before serving for best texture — rolls soften over time.
- Taste the crab mix before rolling and adjust sriracha or mayo to achieve your preferred heat and creaminess.
- If using real crab, handle gently to keep larger flakes intact.
Flavor Variations
- Optional: Spicy Mayo Drizzle — Mix 1/4 cup mayonnaise with 1–2 teaspoons sriracha and drizzle on top for extra heat.
- Optional: Crunch Roll — Add tempura flakes or crushed panko to the filling for a crunchy texture.
- Optional: Citrus Twist — Add a squeeze of lime or a little yuzu kosho to the crab mix for bright citrus notes.
- Optional: Sesame Boost — Sprinkle toasted sesame seeds on the rice before rolling for nuttiness.
- Optional: Vegetarian Swap — Replace crab with mashed sweet potato or seasoned tofu for a meatless roll.
- Optional: Less Heat — Omit sriracha and add a pinch of smoked paprika for a milder, smoky flavor.
Serving Suggestions
- Serve as an appetizer platter with small bowls of soy sauce, pickled ginger, and wasabi.
- Pair with a simple seaweed salad or cucumber sunomono for a light meal.
- Add miso soup or edamame on the side for a fuller dinner.
- Make a sushi party: set up a rolling station with small bowls of fillings and let guests assemble their own.
- Serve with a small green salad and sesame dressing for a balanced meal.
- For a casual gathering, arrange pieces on a wooden board and garnish with thinly sliced scallions.
Make-Ahead, Storage & Reheating
- Make-ahead: Cook rice up to 1 day ahead and store in an airtight container in the fridge. Make crab mix up to a day ahead as well.
- Prep veggies: Slice cucumber and prep avocado just before serving to avoid browning.
- Assembly: It’s best to roll and slice shortly before serving. If you must assemble early, wrap rolls tightly in plastic wrap and refrigerate no more than 3–4 hours.
- Reheating: Sushi is best served cold or at room temperature. Avoid reheating assembled rolls — reheating changes texture and makes rice dry.
Storage and Freezing Instructions
- Refrigerator: Store leftover uncut roll or cut pieces in an airtight container for up to 24–48 hours. Texture will soften after the first day.
- Freezing: Freezing assembled sushi is not recommended. Freezing breaks the rice texture and makes nori soggy.
- Freezing components: You can freeze extra cooked rice (cool it first) for up to 1 month. Thaw in the fridge and steam briefly to restore some moisture. Crab meat can be frozen if raw; imitation crab generally does not freeze well once mixed with mayo.

FAQ About Spicy Crab Sushi
Q: My rice turned out too sticky. What did I do wrong?
A: You likely didn’t rinse enough or used too much water. Rinse until water runs clear and follow package water ratios.
Q: The crab filling is watery. How can I fix it?
A: Drain any liquid from crab meat and pat dry with paper towels before mixing. Use less mayo if needed.
Q: How do I prevent the nori from getting soggy?
A: Spread rice thinly and roll just before serving. Avoid overfilling and store wrapped but not more than a few hours.
Q: Can I use canned crab meat?
A: Yes. Drain and pat dry, then mix with mayo and sriracha. Canned crab is a fine option.
Q: How do I make the roll tighter?
A: Use the bamboo mat to apply even, gentle pressure while rolling. Chill for a few minutes before slicing to firm up.
Q: Can I make this gluten-free?
A: Yes. Use gluten-free soy sauce (tamari) and ensure your imitation crab is gluten-free.
Notes
- Use a sharp knife moistened with water for clean slices.
- Slice avocado right before assembly and rub with a little lime juice to slow browning if needed.
- For clean presentation, wipe your cutting board and knife between rolls.
- If you like a glossy finish, brush a tiny amount of sesame oil on cut pieces just before serving.
- Keep a damp towel over the rice while working to prevent it from drying out.
Troubleshooting
- Problem: Rice is mushy. Fix: Use less water next time and shorten cooking time slightly; rinse rice thoroughly before cooking.
- Problem: Roll falls apart. Fix: Use less filling and press more firmly while rolling; chill briefly before slicing.
- Problem: Filling is bland. Fix: Taste the crab mix and add more sriracha, mayo, or a small pinch of salt.
- Problem: Knife drags and squashes rolls. Fix: Moisten the blade between slices and use a sharp chef’s knife.
- Problem: Avocado browns quickly. Fix: Slice right before serving; a light brush of lime or lemon helps.
- Problem: Nori tastes chewy. Fix: Serve soon after rolling; nori softens with moisture over time.
