Step‑by‑Step Instructions for Nobu Crispy Rice Spicy Tuna
Step 1: Prepare Sushi Rice
Start by rinsing 1 cup of sushi rice under cold water until the water runs clear, removing excess starch. Cook the rice with 1¼ cups of water in a rice cooker or saucepan, bringing it to a gentle boil before reducing the heat. Once the water is absorbed (about 15-20 minutes), allow the rice to sit covered for 10 minutes to steam and become tender.
Step 2: Season Rice
In a small saucepan, combine 2 tablespoons of unseasoned rice vinegar, 1 tablespoon of sugar, and ½ teaspoon of salt over low heat until the sugar dissolves. Once the sushi rice has cooled slightly, fold this mixture into it gently using a wooden spoon, ensuring the rice is evenly coated. Spread the rice on a tray to cool completely as the seasoned flavor develops.
Step 3: Shape and Cut Rice
Lightly grease a baking dish with oil to prevent sticking, then firmly press the cooled sushi rice into it, about 1 inch thick. Chill the rice for at least 30 minutes in the refrigerator. Once set, use a sharp knife to cut the rice into rectangles or squares, ready for frying, which will create the iconic crispy exterior found in Nobu’s Crispy Rice Spicy Tuna.
Step 4: Fry Rice
Heat around 1 cup of vegetable oil in a pan over medium-high heat until it reaches 350°F (180°C). Carefully fry the rice pieces in batches, for about 2-3 minutes on each side, until they are golden brown and crispy. Use a slotted spoon to transfer the fried rice pieces to a plate lined with paper towels, absorbing excess oil while keeping them warm.
Step 5: Make Spicy Mayo
In a mixing bowl, combine ½ cup of Japanese Kewpie mayonnaise, 1 tablespoon of sriracha sauce (or more to taste), 1 teaspoon of soy sauce, and 1 teaspoon of freshly squeezed lime juice. Stir until smooth, creating a flavorful spicy mayo that will complement the crunch of the crispy rice and enhance your Nobu Crispy Rice Spicy Tuna appetizer.
Step 6: Prepare Tuna and Toppings
Dice 8 ounces of sushi-grade ahi tuna into small cubes and mix it in a bowl with a drizzle of soy sauce, freshly squeezed lime juice, and a dash of the spicy mayo. Slice a ripe avocado into thin pieces and, if using, thinly slice jalapeños, removing seeds for milder heat. This mixture of fresh ingredients will add layers of flavor and texture to your finished dish.
Step 7: Assemble
On each crispy rice piece, place a slice of avocado, followed by a generous scoop of the spicy tuna mixture. Add a slice of jalapeño on top for added spice and finish with a sprinkle of sesame seeds for an elegant touch. Serve the assembled Nobu Crispy Rice Spicy Tuna immediately, allowing everyone to enjoy the contrast of flavors and textures at their peak freshness.

Expert Tips for Nobu Crispy Rice Spicy Tuna
- Perfect Rice Texture: Use short-grain sushi rice for the ideal sticky consistency. Avoid using long-grain rice, which won’t hold together as well.
- Frying Temperature: Ensure the oil is at 350°F (180°C) for perfectly crispy rice. A kitchen thermometer will help avoid greasy or undercooked pieces.
- Fresh Fish Matters: Always use sushi-grade fish to guarantee safety and enhance flavor. If unsure, ask your fishmonger for guidance.
- Chill Before Frying: Allow the pressed rice to chill in the refrigerator. This step firms the rice, making it easier to fry without breaking apart.
- Customizable Heat: Adjust the amount of sriracha in the spicy mayo to suit your spice preference. Remember, you can always add more!
- Garnish Wisely: Top with fresh, ripe avocado and optional jalapeños. They not only add flavor but also elevate the presentation of your Nobu Crispy Rice Spicy Tuna.

Nobu Crispy Rice Spicy Tuna Recipe FAQs
What type of sushi rice should I use for this recipe?
Absolutely! Use short-grain Japanese sushi rice. It’s crucial for getting that sticky texture that holds the shape well when cutting and frying. Avoid long-grain varieties as they won’t bind together perfectly.
How should I store leftovers?
For the best results, store leftover crispy rice in an airtight container in the fridge for up to 2 days. Keep the spicy tuna topping in a separate container to maintain its flavor and texture—this way, the rice won’t get soggy!
Can I freeze the crispy rice?
Yes, you can freeze the cooked sushi rice! Here’s a step-by-step guide:
- Once the rice is fully cooled, portion it into individual servings.
- Wrap each portion tightly in plastic wrap or place it in a freezer bag, removing as much air as possible.
- Label and date the bags, storing them in the freezer for up to 3 months.
- When ready to enjoy, reheat in the oven at 375°F (190°C) for 10-15 minutes, ensuring they become crispy again. Just remember, it’s best to assemble once you’ve reheated for optimal freshness!
What should I do if my crispy rice falls apart while frying?
Very! If your rice is falling apart, it’s likely that it hasn’t chilled properly after pressing it into shape. Make sure to chill it in the refrigerator for at least 30 minutes before frying. Additionally, ensure the oil is at the correct temperature of 350°F (180°C) while frying; too low oil temperature can lead to soggy rice!
Are there any dietary restrictions I should be aware of?
