Crispy rice topped with spicy tuna has become a modern sushi bar classic, popularized by restaurants such as Nobu, where it has become one of their signature dishes. While the exact origin of the dish is debated, it has inspired countless variations and remains a favorite for its contrast of textures.
This version starts with seasoned sushi rice that is pressed, chilled, cut into rectangles, and pan-fried until crisp and deeply golden. Each piece is topped with creamy spicy ahi tuna and finished with a generous spoonful of tobiko—red, black, or green wasabi—so every bite offers a slightly different experience.
The magic is in the contrast: warm, crunchy rice against cool, silky tuna, with the tobiko adding bursts of briny flavor and a satisfying pop. The result is a bite that’s crisp, creamy, savory, and just a little spicy—one that’s as fun to eat as it is beautiful to look at.
To plate this, I used a 2.16 × 1.4-inch rectangle cookie cutter as a mold to hold the tuna in place and keep the tobiko from falling far off onto the plate. I also used the same cookie cutter to cut out perfect rectangles of rice for frying.
Where to Get Tobiko

This recipe calls for “sushi-grade” tuna since we are eating it raw.
What “Sushi Grade” Actually Means (and Doesn’t)
“Sushi grade” and “sashimi grade” get thrown around like they’re an official stamp of approval — they aren’t. There’s no USDA or FDA certification behind the term. No government inspector signs off on a fish and declares it “sushi grade.” It’s a designation the seafood merchant applies themselves, based on their own standards for freshness, handling, and sourcing.
The one place federal regulation does enter the picture is around parasite risk. The FDA has freezing guidelines — commonly citing something like freezing at -4°F for 7 days, or -31°F until solid followed by storage at -31°F for 15 hours — designed to kill parasites in fish destined to be eaten raw. But even that isn’t a blanket rule; some species (certain tuna, most farmed salmon) are considered low-risk enough to be exempt.
In other words: “sushi grade” tells you the seller believes the fish is safe to eat raw at the moment you bought it. It says nothing about what happens after that. The responsibility shifts to you the second it’s in your hands. I bring a cooler packed with ice every single time I pick up fish from a trusted seafood counter — whether I plan to eat it raw or cook it — because keeping the cold chain unbroken is what actually keeps you safe, not the label on the package.
There’s a lot more nuance to sourcing raw-grade seafood responsibly, but that’s a deep dive for another post.
Crispy Rice with Spicy Tuna & Tobiko Trio
Ingredients
Crispy Rice
- 3 cups cooked sushi rice
- 3 tablespoons seasoned rice vinegar
- Neutral oil grapeseed, canola, or rice bran, for shallow frying
- Flaky sea salt
Spicy Tuna
- 12 ounces sushi-grade ahi tuna small diced
- 3 tablespoons Kewpie mayonnaise
- 2 teaspoons sriracha or to taste
- 1½ teaspoons toasted sesame oil
- 1½ teaspoons soy sauce
- 1½ teaspoons finely sliced scallions
- 1 teaspoon toasted sesame seeds
- 1 teaspoon chili crisp oil optional
Tobiko Trio & Garnish
- Red tobiko for topping 6 pieces
- Black tobiko for topping 6 pieces
- Green wasabi tobiko for topping 6 pieces
- White sesame seeds for garnishing the black tobiko pieces
- Microgreens for garnishing the red tobiko pieces
- Chives finely sliced for garnish
Instructions
- Prepare the rice: While the rice is still warm, gently fold in the seasoned rice vinegar. Line one end of a 9x13-inch baking dish with parchment or plastic wrap. Press the rice into a rectangle approximately 9x6 inches, about 3/4 inch thick. Cover and refrigerate for at least 4 hours, preferably overnight.
- Make the spicy tuna: In a chilled bowl, gently combine the diced tuna, Kewpie mayonnaise, sriracha, sesame oil, soy sauce, scallions, sesame seeds, and chili crisp oil (if using). Refrigerate until ready to assemble.
- Cut the rice: Invert the chilled rice slab onto a cutting board. Cut into 18 rectangles (3 rows by 6 columns). I used a 2.16 × 1.4-inch rectangle cookie cutter to cut out little rectangles of rice.
- Fry the rice: Heat about 1/4 inch of neutral oil in a cast-iron skillet over medium-high heat. Fry the rice until deep golden and crisp, about 3-4 minutes per side. Transfer to a wire rack and lightly season with flaky sea salt right away while it's still wet so the salt will cling to it.
- Assemble: Top each crispy rice rectangle with about 1 tablespoon of the spicy tuna mixture. Finish six pieces with black tobiko and a scatter of white sesame seeds, six pieces with red tobiko and microgreens, and six pieces with green wasabi tobiko. I used the 2.16 × 1.4-inch rectangle cookie cutter as a mold to hold the tuna in place for the topping of each piece.
