The magic behind this Spicy Tuna Crispy Rice (Nobu Copycat) Recipe lies in its simplicity and the freshness of each component. Every ingredient plays a key role in creating the balance of flavors and textural contrast—from the perfectly seasoned sushi rice to the creamy, spicy tuna topping.

Sushi Rice: 1.5 cups sushi rice, rinsed until water runs clear to ensure a non-sticky, fluffy base.
Water: 2 cups, for perfectly cooking the sushi rice to ideal tenderness.
Salt: 1 teaspoon, to season the rice subtly and enhance flavor complexity.
Rice Vinegar: 3 tablespoons, essential for that classic sushi rice tanginess.
Granulated Sugar: 1 tablespoon, balances the vinegar’s acidity perfectly.
Sesame Oil: 1 teaspoon for the rice, plus 2 teaspoons for the tuna mix; adds a toasty, nutty note that elevates the overall dish.
Ahi Tuna (Sushi Grade): 1 pound finely chopped, the star protein that brings freshness and silky texture.
Japanese Kewpie Mayonnaise: 3 tablespoons, richer and creamier than regular mayo, perfectly smooths the spicy tuna mixture.
Sriracha: 2 tablespoons, provides that fiery kick but can be adjusted based on your spice preference.
Soy Sauce: 1 tablespoon, preferably a version suited for sushi or sashimi to add depth and umami.
Lime Juice: 1 to 2 teaspoons, brightens the tuna mix with a refreshing citrus tang.
Avocado: Thinly sliced, to add creaminess and freshness as a gorgeous topping.
Toasted Sesame Seeds: For garnish, add a subtle crunch and nuttiness.

How to Make Spicy Tuna Crispy Rice (Nobu Copycat) Recipe

Step 1: Prepare and Flavor the Sushi Rice

Start by rinsing your sushi rice several times until the water runs clear—this is crucial for that perfect sticky yet light texture. Then, cook the rice with water and salt until tender. While it’s still warm, gently fold in a mixture of rice vinegar, sugar, and sesame oil to season the rice delicately and give it that addictive sushi-rice flavor that will form the crispy base.

Step 2: Shape and Chill the Rice

Press the seasoned rice into a small square baking tray lined with plastic wrap, forming an even 1/2-inch-thick block. Refrigerate this block for at least an hour; chilling makes slicing easier and helps the rice keep its shape when frying. If you’re short on time, freezing it for about 30 minutes works as a handy shortcut!

Step 3: Cut and Pan Fry the Rice Cubes

Once chilled, slice the rice into bite-sized rectangles—you want pieces that will crisp beautifully but stay tender inside. Heat a thin layer of vegetable oil in a skillet over medium-high heat, then carefully pan-fry the rice pieces, giving them about 3 minutes per side until they turn a gorgeous golden brown and crunchy. Place them on a wire rack to drain excess oil, so each piece stays crisp and light.

Step 4: Prepare the Spicy Tuna Mix

In a mixing bowl, combine the finely chopped ahi tuna with Kewpie mayonnaise, sriracha, soy sauce, sesame oil, and lime juice. This mixture should have a perfect balance of creamy, spicy, salty, and citrusy notes. Adjust the lime and sriracha amounts to your taste for mild or fiery results. Mix until everything is fully incorporated and beautifully vibrant.

Step 5: Assemble Your Spicy Tuna Crispy Rice (Nobu Copycat) Recipe

Top each crispy rice rectangle with a thin slice of avocado for a creamy contrast. Then, dollop 1-2 tablespoons of your spicy tuna on top, ensuring each piece gets that luscious, flavorful punch. Finally, sprinkle with toasted sesame seeds, minced chives or scallions, and a slice of jalapeño or serrano pepper for a fresh and spicy finish. Each bite is a blend of textures and flavors that will make you smile.

Garnishes

Garnishing is where you can add your personal flair. Beyond the suggested sesame seeds, chives, and pepper slices, try a drizzle of unagi sauce or a few microgreens for color contrast and extra flavor layers. These garnishes not only make the dish look stunning but enhance the taste of the spicy tuna and crispy rice perfectly.

Side Dishes

This dish shines as an appetizer but pairs wonderfully with light sides. A simple seaweed salad, pickled ginger, or edamame provide freshness and offset the heat. Alternatively, a cold cucumber salad with sesame oil dressing complements the crispy rice texture and spicy topping elegantly.

Creative Ways to Present

For a fun presentation, serve your spicy tuna crispy rice on slate boards or wooden platters arranged with small dipping bowls of soy sauce or spicy mayo. Stack the rice pieces into small towers and skewer them with decorative toothpicks for parties. You could even turn these into mini bites on lettuce cups for a bite-sized sushi experience that’s as eye-catching as it is delicious.

Make Ahead and Storage

Storing Leftovers

You can store leftover crispy rice separately from the spicy tuna mix in airtight containers in the refrigerator. The rice will retain some of its crispness if stored properly, but best to consume within 1-2 days to enjoy the freshest flavors and textures.

Freezing

Freezing is a bit tricky because the texture of fried rice can change when thawed. You can freeze the uncooked shaped rice block before frying for up to 1 week. When ready to use, thaw it in the fridge and pan fry as usual. The spicy tuna topping should not be frozen to maintain its freshness and texture.

Reheating

For the best texture when reheating crispy rice, give the pieces a quick pop in a hot skillet or a toaster oven rather than microwaving. This will help revive the crispness. Avoid reheating the spicy tuna mix; serve it cold on the reheated rice for the best taste and safety.

FAQs

Can I use a different type of fish instead of ahi tuna?

Absolutely! While ahi tuna is traditional and provides a clean, buttery flavor, you can substitute with salmon or yellowtail if you prefer. Just make sure your fish is sushi-grade for safety and taste.

How spicy is this Spicy Tuna Crispy Rice (Nobu Copycat) Recipe?

The heat mainly comes from the sriracha and pepper slices. You can easily adjust the spiciness by reducing the sriracha amount or leaving out the jalapeños. It’s a versatile recipe that suits mild to spicy preferences.

Can I make the rice crispy without using a lot of oil?

If you prefer less oil, try using a non-stick skillet and fry with a thinner layer of oil, turning frequently. The rice won’t be as deeply golden but will still have a pleasant crisp. Another option is using an air fryer for a lighter crunch.

Is there a vegetarian version of this recipe?

You can make a vegetarian version by swapping the spicy tuna mix for a spicy marinated tofu or diced avocado with a similar sauce blend. The crispy rice remains the same, offering that delightful texture contrast.

Can I prepare this recipe ahead for a party?

Yes! Prepare the rice and spicy tuna separately in advance and assemble just before serving to keep everything fresh and crispy. This recipe is perfect for impressing guests with minimal last-minute effort.
