How to Make Crispy Rice Tuna Sushi Bits (Nobu Copycat Recipe)

Crispy rice spicy tuna bites are a flavor-packed appetizer that first gained popularity at the world-renowned Nobu restaurant, known for its elegant Japanese-fusion cuisine.

While this dish isn’t something traditionally found in Japan, where sushi typically takes the form of simple nigiri, maki rolls, or hand-shaped temaki, it draws inspiration from Japanese ingredients and textures.

In a way, it echoes the spirit of yaki onigiri (grilled rice balls), but adds a bold twist with a creamy, spicy tuna topping. The real magic of this dish lies in the contrast: a golden, crispy base topped with a rich and savory tuna mixture. That combination of crunch and creaminess, heat and umami, is what makes every bite so satisfying.

To make it at home, press cooked and seasoned sushi rice into a flat layer, chill it until firm, then cut it into bite-sized squares or rectangles. Fry each piece in oil at around 175–180°C (350–360°F) for 3–4 minutes per side, until evenly crispy. Chilling the rice beforehand helps it hold its shape and gives it a better crunch.

The spicy tuna topping is usually made with sashimi-grade raw tuna, Japanese mayo, sriracha, and a splash of soy sauce, but you can adjust it to taste with sesame oil, green onions, or jalapeño. For serving, top the crispy rice with avocado slices, sesame seeds, or a drizzle of unagi sauce for extra flavor.

These bites are perfect for parties, date nights, or as a fun, elevated starter. They also pair beautifully with other Nobu-inspired favorites, such as miso black cod, a dish that shares the same balance of simplicity and sophistication.

Though rooted in Japanese ingredients, crispy rice spicy tuna bites offer a creative and approachable way to enjoy sushi-style flavors with a playful, crowd-pleasing twist!
