For 4 servings
- prep · ~2 min
Rinse the sushi rice.
Place rice in a fine-mesh sieve and rinse under cold running water, gently agitating with your fingers, until the water runs clear. Drain well.
- steam · ~25 min
Cook the rice.
Combine rinsed rice and water in a rice cooker or medium saucepan. If using a saucepan, bring to a boil, cover with a tight lid, reduce heat to the lowest setting, and cook undisturbed for 15 minutes. Remove from heat and let stand covered for 10 minutes.
- mix · ~5 min
Season the rice.
In a small bowl, stir together rice vinegar, sugar, and salt until dissolved. Transfer hot rice to a large mixing bowl. Drizzle the vinegar mixture evenly over the rice and use a rice paddle to gently fold and cut through the rice — don't mash it. Fan the rice while folding until it cools to just warm and looks glossy.
TIPFanning the rice gives it that classic sushi-bar shine and the right sticky-cool texture. - mix · ~2 min
Make the spicy tuna filling.
In a medium bowl, combine cubed tuna, mayonnaise, sriracha, soy sauce, and sesame oil. Fold gently until the tuna is evenly coated. Taste and adjust with an extra drop of sriracha if you prefer more heat.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use sashimi-grade tuna only; freshness is critical for raw consumption.
- 2Fan the seasoned rice while folding to remove excess moisture and achieve a glossy finish.
- 3Keep your hands slightly damp with a bowl of water (vinegar water works too) to prevent rice from sticking.
- 4Assemble rolls just before serving — nori loses its crunch within minutes after contact with rice.
- 5Slice avocado just before assembling to prevent browning; brush with a little citrus if needed.
- 6For the tightest cone, fold the bottom-left corner first, then roll upward, sealing with a rice grain.
Adapt it for your goals.
Salmon or Hamachi
Substitute the tuna with sashimi-grade salmon or yellowtail (hamachi) — both offer a buttery richness that pairs beautifully with the spicy mayo.
Low Carb / KetoLow-Carb / Keto
Replace sushi rice with finely chopped cauliflower rice seasoned with the same vinegar-sugar-salt mixture; reduces carbs drastically while keeping the hand-roll concept intact.
Vegan / Plant BasedVegan / Plant-Based
Swap tuna with marinated and diced hearts of palm or tomato 'tuna' (salt-brined and smashed cherry tomatoes), and use vegan mayo — retains the creamy-spicy profile without animal products.
Spicy MangoSpicy Mango
Add thin mango slices alongside the avocado for a sweet tropical contrast that balances the heat from sriracha and the richness of the tuna.
Crunchy TempuraCrunchy Tempura
Top the filling with a sprinkle of store-bought tempura flakes (tenkasu) for an extra layer of crunch just before rolling.
Why this is on our healthy list.
Rich in Omega-3s
Sashimi-grade tuna is an excellent source of heart-healthy omega-3 fatty acids, which support brain function and reduce inflammation.
Healthy Fats from Avocado
Avocado provides monounsaturated fats that help absorb fat-soluble vitamins and promote satiety without raising bad cholesterol.
Lean Protein Boost
Each hand roll delivers a substantial amount of high-quality, low-fat protein from the tuna, essential for muscle repair and maintenance.
Digestive Support
Cucumber adds hydration and fiber, while the pickled ginger aids digestion and the rice provides easily digestible carbohydrates.
Low in Processed Ingredients
This recipe uses minimal processed foods — just nori, sesame oil, and a touch of mayonnaise — making it a relatively whole-food-focused sushi option.
Frequently asked questions
Short-grain sushi rice is key for its sticky, cohesive texture; long-grain rice won't hold the hand-roll shape and will fall apart easily.
