Spicy Crispy Tuna Recipe

1. Prepare tuna

Pat the tuna loin dry with paper towels. Trim any sinew and cut the tuna into 6 equal rectangular pieces (about 3 oz / approx. 85 g each). Keep the pieces uniform so they cook evenly.

2. Marinate

In a shallow bowl, whisk together soy sauce, sesame oil, Sriracha, rice vinegar, grated ginger, minced garlic, kosher salt, and black pepper. Place the tuna pieces in the bowl and spoon marinade over them to coat. Marinate for 10–15 minutes at room temperature (no more than 20 minutes to avoid 'cooking' the tuna). Reserve the remaining marinade for brushing if desired.

3. Make dredging stations

Set up three shallow dishes: 1) flour and cornstarch mixed together; 2) eggs beaten with 3 tablespoons cold water until combined; 3) panko mixed with optional fine breadcrumbs, crushed nori, and sesame seeds. Season the flour and panko lightly with a pinch of salt and pepper.

4. Coat tuna

Remove each tuna piece from the marinade, letting excess drip off. Dredge first in the flour mixture, shaking off excess. Dip into the egg wash, allowing extra to drip off, then press into the panko mixture to fully coat all sides. For an extra-thick crust, repeat egg wash and panko step once. Place coated pieces on a wire rack briefly while you heat the oil.

5. Heat oil

Pour neutral oil into a heavy skillet or frying pan to a depth of about 1/4 inch (roughly 1 cup depending on pan). Heat over medium-high until the oil reaches 350°F (175°C) or until a pinch of panko sizzles immediately. If you don't have a thermometer, test with a small breadcrumb — it should brown in about 30–40 seconds.

6. Fry tuna

Carefully add tuna pieces to the skillet, leaving space between them. Fry for 30–45 seconds per side for a very rare interior (recommended for sushi-grade tuna) or 60–75 seconds per side for medium-rare. Adjust time depending on thickness. Use tongs or a spatula to turn gently so the crust stays intact. Total cook time per piece should be about 1–2.5 minutes depending on doneness preference.

7. Drain and rest

Transfer fried tuna to a wire rack set over a baking sheet or to paper towels to drain briefly. Let rest 1–2 minutes — this helps the crust set and the interior equilibrate.

8. Slice (optional)

For serving, you may slice each piece into 2–3 diagonal slices (to make 12–18 bite-sized pieces) or serve whole as 6 pcs. If slicing, use a very sharp knife and wipe the blade between cuts for clean edges.

9. Plate and garnish: Arrange the 6 pieces (or sliced pieces) on a serving plate. Drizzle or dollop spicy mayo alongside and offer soy-ginger dipping sauce. Sprinkle sliced scallions, microgreens or cilantro, and a light squeeze of lime over the tuna. Serve immediately while crust is crisp.
