Ingredients You'll Need
The magic of the Nobu Crispy Rice Spicy Tuna Recipe lies in its straightforward yet carefully chosen ingredients. Each component plays a crucial role in delivering that fantastic blend of texture, flavor, and visual appeal, so don’t skip out on these essentials.
- Sushi rice: Short grain rice is sticky and perfect for molding into crispy blocks that hold their shape.
- Water: Used to cook the rice just right for a perfect soft interior.
- Unseasoned rice vinegar: Adds subtle tang that brightens the rice and balances richness.
- White granulated sugar: Slightly sweetens the rice seasoning to enhance overall flavor.
- Salt: Enhances the natural taste and rounds out the seasoning.
- Vegetable oil: For frying the rice, choose a neutral oil with a high smoke point for a crisp finish.
- Sushi-grade ahi tuna: The star ingredient, ensuring freshness and silky texture.
- Japanese kewpie mayonnaise: Creamy and slightly sweet mayo that complements the spicy tuna beautifully.
- Sriracha sauce: Adds vibrant heat and a touch of garlicky spice.
- Soy sauce: Brings umami depth to the spicy mayo mixture.
- Lime juice: Fresh acidity that brightens the spicy tuna topping.
- Avocado: Adds creaminess and a gentle buttery flavor that balances the heat.
- Jalapeños: For a fresh, crisp crunch and additional mild heat.
How to Make Nobu Crispy Rice Spicy Tuna Recipe
Step 1: Prepare the Sushi Rice
Start by rinsing your sushi rice under cold water until the water runs mostly clear; this removes excess starch and helps achieve that signature sticky-yet-fluffy texture. Next, cook the rice with water in a covered saucepan—once bubbling starts, lower the heat to gently absorb all the liquid, creating perfectly cooked rice that’s not mushy.
Step 2: Season the Rice
While your rice is cooking, warm the rice vinegar with sugar and salt in a small pan to dissolve all the flavors evenly. When your rice is ready, gently fold this seasoning into the rice and press it firmly into a baking dish. This step is important because it helps the rice hold together when frying and infuses it with subtle flavor.
Step 3: Chill and Cut
Allow the rice to cool to room temperature and then chill it for at least 30 minutes. This chilling step makes it easier to slice the rice into firm rectangles or your preferred shapes without crumbling. I usually cut mine into 15 rectangles—each about the right size to be a delightful finger food.
Step 4: Fry the Rice
Heat about half an inch of vegetable oil in a skillet until it reaches around 350°F. Carefully fry the rice pieces on each side until golden and crispy, usually 2-3 minutes per side. The goal is a satisfying crunch outside with a tender interior, and the oil temperature is key to getting this just right.
Step 5: Prepare the Spicy Tuna Mixture
In a medium bowl, combine kewpie mayonnaise, sriracha, soy sauce, and lime juice. Then, finely chop your sushi-grade tuna and mix it thoroughly into this spicy sauce. The mayo provides creaminess, while the sriracha and lime juice add heat and brightness that make each bite exciting.
Step 6: Assemble and Garnish
Slice avocado into thin, firm pieces and get your jalapeños ready (removing seeds if you prefer milder heat). To serve, place a few avocado slices on each crispy rice block, top with the spicy tuna mixture, add a slice of jalapeño on top, and finish with a sprinkle of toasted sesame seeds for that nutty touch. Serve immediately for the best texture contrast.

Garnishes
Garnishes elevate this dish visually and flavor-wise. I love adding sesame seeds for nuttiness and a sprinkle of finely chopped green onions or microgreens for freshness. A little drizzle of extra sriracha or a small dollop of wasabi mayo can kick things up a notch, too.
Side Dishes
This crunchy, spicy tuna dish pairs wonderfully with simple sides like a light seaweed salad or pickled ginger to cleanse the palate. A crisp cucumber salad with rice vinegar dressing keeps the meal fresh and balances the richness of the mayo sauce perfectly.
Creative Ways to Present
For parties, consider serving the Nobu Crispy Rice Spicy Tuna Recipe on a large wooden board or slate platter with lemon or lime wedges on the side. You can also create mini skewers by stacking the crispy rice and spicy tuna topped with avocado and jalapeño for easy one-bite enjoyment and stylish presentation.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover crispy rice or spicy tuna, store them separately in airtight containers in the refrigerator. The rice is best consumed within 24 hours to avoid sogginess, while the tuna mixture will stay fresh for up to 2 days.
Freezing
Freezing is not ideal for crispy rice since it tends to lose its texture once thawed. However, if necessary, freeze only the un-fried rice blocks tightly wrapped and use within a week. The spicy tuna should never be frozen, as the raw fish texture will degrade.
Reheating
To reheat the rice, gently pan-fry it again in a little oil to regain its crispy exterior. Avoid microwaving because it will soften the texture. Always add the tuna mixture fresh to preserve its vibrant flavor and creaminess.
FAQs
Can I use canned tuna instead of sushi-grade ahi tuna?
Yes, you can substitute canned tuna for sushi-grade ahi if needed. Just make sure to drain it well and choose a good-quality tuna packed in water. The flavor and texture won’t be exactly the same, but it still makes a tasty spicy topping.
Is it necessary to use Japanese kewpie mayonnaise?
While traditional mayonnaise works, Japanese kewpie mayo is whiskier, slightly sweeter, and richer, which really enhances the flavor and creaminess of the spicy tuna mix. It’s worth seeking out for authenticity and best taste.
Can I make this recipe vegetarian or vegan?
You can try replacing the tuna with diced avocado or marinated mushrooms for a vegetarian take, and use vegan mayo to keep it dairy-free. Just remember it won’t replicate the exact taste, but it’ll still be delicious and fresh.
How do I keep the rice from falling apart during frying?
Chilling the pressed sushi rice block thoroughly before cutting helps it hold together better. Also, press the rice firmly in the pan and handle the pieces gently but confidently when frying. Hot oil and correct temperature are crucial for a sturdy, crispy crust.
What can I serve with Nobu Crispy Rice Spicy Tuna Recipe for a full meal?
This dish pairs nicely with light Asian-inspired sides like miso soup, edamame, or a refreshing cucumber salad, creating an elegant, balanced meal with plenty of texture and flavor variety.

Ingredients
For the Sushi Rice
- 1 cup (210 g) sushi rice (short grain)
- 1 and ¼ cup (310 ml) water
- 2 tbsp (30 ml) unseasoned rice vinegar
- 2 tsp white granulated sugar
- ½ tsp salt
- Vegetable oil (or sunflower or peanut oil, for frying)
For the Spicy Tuna Mixture
- ½ lbs (225 g) sushi-grade ahi tuna (or cured smoked salmon or canned tuna)
- 1 and ½ tablespoon (17 g) Japanese kewpie mayonnaise
- 1 tbsp (15 g) sriracha sauce
- ½ tbsp (7 g) soy sauce
- 1 tsp freshly-squeezed lime juice
- 1 avocado (ripe but still quite firm)
- 1-2 jalapeños
- Sesame seeds (for garnish)
Instructions
- Make the Sushi Rice: Rinse the sushi rice under cold water in a mesh strainer until the water runs mostly clear, approximately 1 to 2 minutes. Transfer the rinsed rice to a large saucepan, add the water, cover with a tight-fitting lid that has a vent hole (or crack the lid open if it doesn’t), and place over medium-high heat. Cook until water begins bubbling, then reduce heat to medium-low and cook until water is fully absorbed. Remove from heat.
- Prepare the Sushi Rice Seasoning: In a small saucepan over low heat, combine the rice vinegar, sugar, and salt. Heat gently until sugar and salt dissolve completely, stirring occasionally, then turn off the heat.
- Season and Shape the Rice: Transfer the cooked rice into an 8” x 8” (20 x 20 cm) baking dish. Gently fold in the vinegar seasoning with a spatula or spoon. Press the rice down evenly to form a block about ½ to 1 inch (1.2 to 2.5 cm) thick. Allow the rice block to cool to room temperature, then cover with plastic wrap and chill in the refrigerator for at least 30 minutes or preferably overnight.
- Cut the Rice: Remove the chilled rice block and use a sharp knife to cut into 15 rectangles. Alternatively, use a small greased cookie cutter for different shapes like squares or circles.
- Fry the Rice: Pour vegetable oil into a medium skillet to a depth of about ½ inch (1.2 cm). Heat the oil over medium heat until it reaches 350°F (180°C), ideally using a kitchen thermometer for accuracy. Fry the rice rectangles for 2-3 minutes on one side until golden and crispy, then flip and fry the other side for another 2-3 minutes. Transfer fried rice to a plate lined with parchment paper to absorb excess oil.
- Make the Spicy Mayo Sauce: In a medium bowl, whisk together Japanese kewpie mayonnaise, sriracha sauce, soy sauce, and freshly squeezed lime juice until smooth and combined.
- Prepare Tuna, Avocado, and Jalapeño: Finely chop the sushi-grade ahi tuna (or smoked salmon or canned tuna). For canned tuna, make sure it is well drained. Cut the avocado by slicing lengthwise around the pit, twisting the halves to separate, removing the pit, peeling off the skin, and slicing the flesh thinly. Finely slice the jalapeños, removing seeds and membranes for less heat if desired.
- Assemble the Crispy Rice Spicy Tuna: Combine the chopped tuna with the spicy mayo sauce. Place a few slices of avocado on each crispy rice rectangle, spoon 1-2 teaspoons of the spicy tuna mixture on top, add a slice of jalapeño, and sprinkle with sesame seeds. Serve immediately and enjoy this flavorful and textural delight!
