Ingredients You’ll Need
Get ready to gather a vibrant palette of ingredients that bring this Dynamite Roll alive—imagine the silky smoothness of ripe avocado mingling with crispy tempura shrimp embraced by the nutty crunch of toasted sesame seeds.
- 1 recipe sushi rice: The essential base providing sticky yet tender texture for perfect rolling.
- 8 oz imitation crab sticks: Flaked into luscious chunks, blended with Japanese mayo to add creaminess.
- 3 Tbsp Japanese mayonnaise: Adds a sweet tang that complements seafood wonderfully.
- 1 avocado (ripe): Offers buttery richness and smoothness.
- 1/2 English cucumber: Fresh crunch balancing the creamier textures.
- 8 sheets toasted nori seaweed (Cut in half): Provides that classic umami wrapper with a hint of smokiness.
- Toasted sesame seeds: Adds a toasty nuttiness on top of the rice.
- Black sesame seeds: Creates visual contrast and deeper flavor bursts.

Ingredient Substitutions & Tips
- Imitation crab sticks: You can swap for cooked real crab meat or flaked cooked shrimp for a fresher seafood taste.
- Japanese mayonnaise: If unavailable, mix regular mayo with a little rice vinegar and a pinch of sugar as a tasty alternative.
- Tempura fried shrimp: If you’re short on time, store-bought frozen tempura shrimp works wonderfully without sacrificing crunch.
- Unagi sauce: Substitute with a mixture of soy sauce and a touch of honey or brown sugar if unagi sauce isn’t at hand.
👨🍳 Pro Tips for Perfect Results
- Prepare sushi rice ahead: Making sushi rice in a rice cooker and letting it cool fully ensures the perfect sticky texture.
- Wrap the bamboo mat: Always wrap your sushi mat in plastic wrap for easy cleanup and better rolling control.
- Keep your hands wet: Wetting hands before handling rice helps prevent it from sticking everywhere.
- Use a sharp, wet knife: For slicing, dip your knife in water before each cut to get clean, intact slices.
- Trim nori if needed: Cutting a quarter off the seaweed sheet balances rice and filling perfectly.
How to Make Spicy Tuna and Tempura Shrimp Dynamite Roll Recipe
Step 1: Make the sushi rice
First things first, cook your sushi rice to perfection—making it in a rice cooker is a game-changer for consistent results. Once it’s fluffy and ready, allow it to cool; this step is crucial to keep the rice sticky but not soggy.
💡 Pro Tip: Spread the cooked rice on a large plate to cool faster and avoid clumping.
Step 2: Prepare crab mixture
Next, finely chop 8 ounces of imitation crab meat and mix it lovingly with 3 tablespoons of luscious Kewpie Japanese mayonnaise in a bowl. This mixture adds creamy texture and subtle sweetness to your roll.
💡 Pro Tip: Taste your crab mix; you can adjust mayo amounts depending on desired creaminess.
Step 3: Wrap sushi mat
Wrap your bamboo sushi mat tightly in plastic wrap to keep it pristine and make rolling easier—trust me, cleanup will be a breeze!
💡 Pro Tip: Stretch the plastic wrap smoothly for an even surface.
Step 4: Prepare nori
Grab one sheet of toasted nori seaweed, place it on the sushi mat, and trim off a quarter with scissors. This small modification helps balance rice and filling for a perfect roll.
💡 Pro Tip: Toast nori briefly over low heat if it’s not pre-toasted to enhance its aroma.
Step 5: Spread rice
Wet your hands to keep the rice from sticking and gently spread a thin, even layer over the nori. Be careful not to press too hard or your roll will turn dense instead of airy.
💡 Pro Tip: Use the back of a spoon to evenly distribute rice if you prefer.
Step 6: Add sesame seeds and flip
Sprinkle a combination of toasted white and black sesame seeds on top of the rice, lending a nutty crunch and contrasting colors. Then carefully flip the seaweed over so the rice side faces down.
💡 Pro Tip: Use a gentle hand to flip so the rice layer stays intact.
Step 7: Add fillings
Place about one ounce of the imitation crab mix, a few cucumber strips, two slices of ripe avocado, and two tempura-fried shrimp (tails removed) along the center of the nori.
💡 Pro Tip: Arrange the tempura shrimp so they lay neatly for better roll shape.
Step 8: Roll sushi
Now comes the fun and tricky part: using your sushi mat, roll the nori tightly around the fillings. Compress just enough to hold everything together without smooshing the ingredients.
💡 Pro Tip: Apply even pressure and take your time for a tight, neat roll.
Step 9: Cut sushi
Transfer the roll to a cutting board and slice into eight equal pieces with a sharp knife dipped in water between cuts to prevent sticking.
💡 Pro Tip: Clean the knife blade with a damp towel after every few cuts for clean edges.
Step 10: Add toppings and serve
Drizzle your rolls with spicy mayo and unagi sauce to bring that rich, fiery, and sweet flavor combo to life. Serve immediately with soy sauce and wasabi for dipping delight.
💡 Pro Tip: Add a sprinkle of extra sesame seeds or finely sliced green onions for garnish.
Common Mistakes to Avoid
Learn from these common pitfalls:
- Using hot rice: Placing warm rice on nori can cause sogginess and tears. Always cool your rice first.
- Pressing the rice too hard: This leads to dense, gummy sushi and poor texture.
- Overfilling the roll: Too many fillings cause the roll to burst apart when slicing or eating.
- Not wetting hands or knife: Rice will stick stubbornly, making rolling and cutting a frustrating mess.
- Skipping the plastic wrap on the mat: Rolling without it often results in rice sticking to the bamboo and a difficult cleanup.
- Using a dull knife: This crushes the roll instead of slicing cleanly, ruining the presentation.
Delicious Variations to Try
Once you’ve mastered the classic Spicy Tuna and Tempura Shrimp Dynamite Roll Recipe, why not mix things up with some tasty twists?
Crunchy Veggie Dynamite Roll
Swap tempura shrimp for crispy tempura sweet potato or asparagus for a delightful vegetarian option that still retains that satisfying crunch.
Spicy Salmon Dynamite Roll
Replace imitation crab with finely chopped fresh salmon mixed with spicy mayo for a melt-in-your-mouth texture and a new flavor profile.
Tofu Tempura Dynamite Roll
For a halal-friendly vegetarian alternative, use tempura-fried tofu cubes alongside avocado and cucumber; it’s hearty and packed with flavor.
Sesame-Crusted Dynamite Roll
Roll the finished sushi lightly in additional sesame seeds to amp up the nuttiness and create an elegant texture contrast perfect for entertaining.
Sweet Mango Dynamite Roll
Add thin slices of juicy mango with the traditional fillings to introduce a tropical sweetness that beautifully balances the spicy mayo.
How to Serve Spicy Tuna and Tempura Shrimp Dynamite Roll Recipe

Garnishes
A sprinkling of toasted sesame seeds, a drizzle of unagi sauce, and a touch of spicy mayo elevate the rolls visually and flavor-wise—don’t forget a side of pickled ginger for palate cleansing!
Side Dishes
Complement your sushi with a light seaweed salad, miso soup, or a crisp cucumber sunomono to keep the meal balanced and refreshing.
Creative Ways to Present
Serve your rolls on a long wooden platter or slate board with small bowls of soy sauce, wasabi, and pickled ginger arranged artfully. For fun, add edible flowers or shiso leaves for a burst of color and fragrance.
Make Ahead and Storage
Make-Ahead Instructions
You can prepare your sushi rice and crab mixture several hours ahead. Keep the rice covered with a damp cloth to prevent it from drying out. Assemble rolls just before serving for the best texture.
Storage
Store plated rolls in an airtight container in the fridge for up to 24 hours. Note that tempura shrimp is best enjoyed immediately for crunchiness, but the rolls remain tasty chilled.
Freezing
This sushi roll is not ideal for freezing as the texture of the rice and tempura shrimp will degrade significantly.
Reheating
Reheat tempura shrimp separately in a hot oven for a few minutes to regain crispness; sushi rolls themselves are best eaten cold or at room temperature.
Expert Tips for Success
- Always cool sushi rice before assembling to prevent sogginess.
- Keep your sushi mat clean and wrapped in plastic for easy rolling and cleanup.
- Use a sharp knife moistened with water for precise, clean slices.
- Don’t rush the rolling step—steady, even pressure makes a perfect roll.
- Fresh, ripe avocado and crisp cucumber make all the difference.
- Add sauces sparingly at first—you can always add more for flavor balance.
- Practice makes perfect; the more rolls you make, the better your technique.

Description
This Dynamite Roll recipe delivers a delightful combination of crispy tempura shrimp, creamy avocado, and flavorful imitation crab meat wrapped in sushi rice and nori, finished with spicy mayo and unagi sauce for a tasty sushi experience at home.
Ingredients
Ingredients
- 1 recipe sushi rice
- 8 oz imitation crab sticks
- 3 Tbsp Japanese mayonnaise
- 1 avocado (ripe)
- 1/2 English cucumber
- 8 sheets toasted nori seaweed (Cut in half)
- Toasted sesame seeds
- Black sesame seeds
- 16 tempura fried shrimp
- Unagi sauce
- Spicy mayo
Instructions
- Make the sushi rice: Make the sushi rice according to the recipe. I highly recommend making the rice in a rice cooker. Then let it cool. Note: my sushi rice recipe makes 8 rolls. But you can cut this in half if needed.
- Prepare crab mixture: Finely chop 8 oz of imitation crab meat and place it into a bowl and mix it with 3 Tbsp of kewpie Japanese mayonnaise. Then set it aside.
- Prepare sushi mat: Now wrap your bamboo sushi mat in plastic wrap. This will make your life a lot easier then it comes to clean up.
- Set up nori: Place 1 sheet of toasted nori seaweed on top off the sushi mat and cut off 1/4 of it with scissors. You don’t have to do this but I find that if you use the full sheet, you end up with too much rice vs filling.
- Spread sushi rice: Now wet your hands in a bowl of water and grab a handful of rice and begin spreading a thin even layer of sushi rice on top of the seaweed. Be careful not to press on the rice too hard, or you’ll end up with a mashed up mess. Continuously wetting your hands will prevent the rice from sticking to your fingers.
- Add sesame seeds and flip: Now sprinkle toasted white sesame seeds along with black sesame seeds on top of the rice. Then flip the entire sheet of seaweed over.
- Add fillings: Now, in the middle of the seaweed, add about 1 oz of the imitation crab meat mixture, a few strips of cucumber, and two slices of avocado, and 2 tempura fried shrimp (tails off).
- Roll sushi: Now, this is the tricky part. While turning in the front of the nori with the sushi mat, slightly compress the inner ingredients. Keep rolling the sushi with the sushi mat, making sure to keep the roll tight.
- Slice roll: Place the sushi roll onto a cutting board and use a sharp wet knife, cut the sushi into 8 equal pieces. I usually wet the knife before each slice.
- Serve: Then top with spicy mayo and unagi sauce, and serve with soy sauce and wasabi.
Notes
- Use a rice cooker for the sushi rice for best results.
- Wrap the bamboo sushi mat in plastic wrap for easier cleanup.
- Wet your hands and knife to prevent sticking while shaping and cutting sushi.
- Cut nori sheets to prevent too much rice compared to filling.
