Spicy Tuna Crispy Rice Recipe

I created this Spicy Tuna Crispy Rice recipe as a home-friendly version of the iconic Nobu dish. It starts with compact sushi rice that is chilled and pan-fried until golden and crispy, then topped with a creamy, spicy tuna mixture. It makes a show-stopping appetizer or a fun bite-sized meal.

Why You’ll Love This Recipe

I love how the crunchy rice contrasts with the tender, flavorful tuna topping. The mix of spicy, sweet, and umami notes combined with creamy avocado and a hint of jalapeño is pure bliss. It’s elegant, easy to prep ahead, and terrific for entertaining or a special weeknight treat.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Rice

• Sushi-grade short- or medium-grain rice

• Rice vinegar, sugar, salt

• Neutral oil for frying

Tuna Mixture

• Sushi-grade ahi tuna, finely diced

• Japanese mayonnaise (Kewpie or regular mayo)

• Sriracha or chili crisp

• Soy sauce or tamari

• Sesame oil

• Optional: lime juice, sliced scallion

Toppings (optional)

• Thin slices of avocado

• Jalapeño or serrano slices

• Black or white sesame seeds

Directions

1. I rinse and cook sushi rice per package instructions, then toss it with rice vinegar, sugar, and salt while still warm.

2. I press the seasoned rice firmly into a square pan lined with plastic wrap, forming a compact block, then chill it for at least 2–3 hours or freeze briefly to speed it up.

3. Once chilled, I flip out the rice block and slice it into rectangles or squares about 1½–2 inches wide.

4. I heat neutral oil in a skillet or shallow pan to about 350°F and fry the rice pieces without crowding, about 3–4 minutes per side, until golden and crisp. I transfer them to a wire rack.

5. While the rice chills, I finely dice the tuna and mix it with mayo, sriracha or chili crisp, soy sauce, sesame oil, scallions, and lime if using. I chill that as well.

6. I assemble by topping each crispy rice cake with a spoonful of tuna mix. I garnish with avocado, jalapeño, and sesame seeds.

Servings And Timing

This recipe yields about 14–16 bite-sized pieces or roughly 8 more generous servings.

• Prep time: 25–30 minutes

• Chill time: 2–4 hours (can be reduced with freezing)

• Cook/fry time: 20 minutes

• Total time: About 2½ to 3 hours (mostly inactive time)

Variations

• I sometimes air-fry the rice instead: brush lightly with oil and air-fry at 370–400°F for about 10–12 minutes, flipping once.

• I substitute salmon for tuna when desired.

• I adjust the spice level by varying the amount of sriracha or using lime juice for a citrusy twist.

• For a vegan version, I use mashed chickpeas or sweet potato in place of the tuna.

Storage/Reheating

This dish is best enjoyed the same day, as the rice loses its crispiness over time. If storing leftovers, I keep the rice and tuna mixture in separate airtight containers in the fridge for up to 2 days. To reheat, I crisp the rice in a skillet or air-fryer. The tuna mix I serve chilled.

FAQs

What Type Of Rice Should I Use?

I always use sushi-grade short- or medium-grain rice because it’s sticky enough to hold together after frying.

Can I Prepare Anything In Advance?

I often prepare the rice block and tuna mixture the night before. I keep them chilled and assemble just before serving.

Can I Reduce The Chill Time?

Yes, I sometimes freeze the rice block for 30–60 minutes and then refrigerate briefly. This helps firm it up quickly for slicing and frying.

Is Pan Frying Or Air Frying Better?

Pan frying delivers a deeper golden color and crunch, but I like using the air fryer for a healthier and easier option.

How Spicy Is It By Default?

It can be moderately spicy, depending on the amount of sriracha or chili crisp. I adjust to taste by reducing or increasing the heat.

Conclusion

I love making this Spicy Tuna Crispy Rice when I want an impressive appetizer or snack that feels gourmet but is easy to prepare. With crunchy rice, spicy tuna, creamy avocado, and a kick of jalapeño, every bite delivers a burst of flavor. I prep most components in advance so the final dish comes together quickly and beautifully.
