Crispy Tempura Nori Tuna Tacos Tips, FAQ & printable recipe

Tips for success

For the crispiest shells, keep the batter as cold as possible. Use ice-cold sparkling water and, if needed, set the batter bowl over a larger bowl of ice.

Fry in small batches to maintain the oil temperature. Do not overcrowd the pot, as this drops the heat and makes the shells greasy.

When assembling, use a light hand with the filling. Too much moisture from the mango or mayo can soften the shell. Serve immediately after garnishing.

If making multiple batches, keep the fried shells warm in a low oven on a wire rack, but note they are best eaten fresh.

Variations

• Spicy Tuna Version: Swap the yellowtail for sushi-grade tuna and toss with a bit of sriracha mayo instead of yuzu kosho ponzu. Keep the mango and serrano for a sweet-heat balance.
• Vegetarian Option: Replace the fish with diced avocado and cucumber, and use a soy-based sauce instead of ponzu. The crispy nori shell and rice make it a satisfying meatless meal.
• Mango Salsa Twist: Instead of separate mango and serrano, mix them with a little lime juice and cilantro to make a quick salsa. Spoon it over the fish and rice.
• Shrimp Tempura Taco: Add small cooked shrimp to the filling for extra protein. Toss the shrimp with the yuzu ponzu and mix with the yellowtail for a surf-and-turf taco.

Storage and make-ahead

Fridge

Store leftover fish and rice separately in airtight containers in the refrigerator for up to 1 day.

Freezer

Do not freeze the assembled tacos; the texture will suffer.

Reheat

Reheat leftover nori shells in a 350°F oven for 3-5 minutes to restore crispness. Avoid microwaving.

Store any leftover fried nori shells separately from the filling in an airtight container at room temperature for up to 1 day. The fish and rice should be refrigerated. Reheat the shells in a 350°F oven for a few minutes to re-crisp.

The sushi rice can be cooked and seasoned a day ahead and kept refrigerated. The yellowtail can be diced and marinated up to 2 hours in advance, stored in the fridge.

The batter is best made fresh, but the nori shells can be fried a few hours ahead and reheated.

Serving ideas

Serve these tacos as a fun appetizer for a party or as a main course for a casual dinner. Arrange them on a platter with extra spicy mayo on the side. The contrast of temperatures—warm shell, cool fish—makes each bite exciting.

Pair with a crisp lager or a citrusy sake. The bright yuzu and mango flavors also work well with a dry Riesling.

For a complete meal, add a simple green salad or edamame. These tacos are best enjoyed immediately, while the shells are at their peak crunch.

Crispy Tempura Nori Tuna Tacos

Prep 20 minCook 10 minTotal 30 minServes 4

Ingredients

• 8 half-sheet nori (cut into half-moons)
• 1 cup ice-cold sparkling water
• 1 cup all-purpose flour
• 2 tbsp cornstarch
• 1/2 tsp kosher salt
• 200 g yellowtail (hamachi), diced
• 1 tbsp yuzu kosho ponzu
• 1/2 cup diced mango
• 1 serrano pepper, thinly sliced
• 2 cups cooked sushi rice
• spicy mayo, for drizzling, to taste
• crispy fried shallots, for sprinkling, to taste

Instructions

1. In a large bowl, whisk together the all-purpose flour, cornstarch, and kosher salt. Slowly pour in the ice-cold sparkling water while whisking gently until just combined; the batter should be lumpy and thin. Keep the bowl over an ice bath if possible. Cut the half-sheet nori into half-moon shapes by folding each sheet in half and cutting along the fold with scissors. Dice the yellowtail into small, even cubes and toss with the yuzu kosho ponzu in a separate bowl. Set aside in the refrigerator.
2. Dice the mango into small, bite-sized pieces and thinly slice the serrano pepper. Have the sushi rice ready at room temperature. Set up a station with the batter, nori, and a plate lined with paper towels for draining.
3. Pour about 2 inches of neutral oil (such as canola or vegetable) into a large heavy-bottomed pot. Heat over medium-high until a deep-frying thermometer reads 365°F (185°C). Adjust the heat to maintain the temperature.
4. Dip each nori half-moon into the batter, coating only one side. Let the excess drip off briefly. The nori should be fully covered on the dipped side but still visible on the other.
5. Place the battered nori half-moon into a taco tong mold and carefully lower it into the hot oil. Fry for about 90 seconds, turning once, until the batter is puffed and golden brown. Remove with a slotted spoon and drain on paper towels. Repeat with the remaining nori.
6. Let the fried nori shells rest on paper towels for a minute. They will crisp up as they cool. Keep them in a warm oven (200°F) if frying in batches.
7. Spoon a small amount of sushi rice into each crispy nori shell, spreading it gently along the bottom. Top with the diced yellowtail mixture, then add mango and serrano slices.
8. Drizzle spicy mayo over the filled tacos and sprinkle with crispy fried shallots. Serve immediately while the shells are still crisp.
