Tempura fish tacos are a delicious blend of crunchy, golden-battered fish tucked inside soft tortillas, topped with a refreshing slaw, and finished with a squeeze of lime. This recipe combines the light crispiness of Japanese-style tempura with the bold, zesty flavors of Mexican street food. The result is a meal that’s not only satisfying but also quick to prepare at home.
Whether you’re looking for a casual weeknight dinner, a weekend gathering centerpiece, or a fresh twist on traditional tacos, these tempura fish tacos are guaranteed to impress.
Why Tempura Fish Tacos?
Fish tacos are already popular for their lightness and versatility. But making the fish tempura-style elevates them to another level. The batter creates a delicate crunch without being greasy, keeping the fish moist and flavorful. Paired with a tangy slaw and warm tortillas, every bite is the perfect balance of textures and flavors.
These tacos are also endlessly customizable. You can add avocado, drizzle with a spicy crema, or toss in pickled jalapeños for extra heat. That’s the beauty of tacos—you can make them your own.
Ingredients You’ll Need
The recipe has three main components: the tempura fish, the slaw, and the tacos themselves. Let’s break it down:
For the Tempura Fish
- 1 lb (450 g) white fish fillets (such as cod or tilapia), cut into strips
- 1 cup all-purpose flour
- ½ cup cornstarch
- 1 tsp baking powder
- ½ tsp salt
- 1 cup ice-cold sparkling water
- Vegetable oil, for frying
For the Slaw
- 2 cups shredded cabbage (green or purple)
- 1 small carrot, julienned
- 2 green onions, thinly sliced
- 2 tbsp mayonnaise
- 1 tbsp lime juice
- 1 tsp honey
- Salt and pepper, to taste
For the Tacos
- 8 small flour or corn tortillas
- Fresh cilantro, for garnish
- Lime wedges, for serving
- Optional: sliced avocado or pickled jalapeños
Step-by-Step Instructions
1. Prepare the Slaw
The slaw adds crunch and freshness to balance the crispy fish.
- In a medium bowl, combine the shredded cabbage, julienned carrot, and sliced green onions.
- In a small separate bowl, whisk together mayonnaise, lime juice, honey, salt, and pepper until smooth.
- Toss the dressing with the cabbage mixture until everything is well coated.
- Cover and refrigerate until serving. This allows the flavors to blend while you prepare the rest of the dish.
2. Make the Tempura Batter
The secret to light, airy tempura is using cold sparkling water.
- In a large bowl, whisk together flour, cornstarch, baking powder, and salt.
- Gradually add the ice-cold sparkling water while whisking gently. Do not overmix—small lumps are perfectly fine.
- The batter should be slightly thick yet still pourable. If it seems too thick, add a splash more sparkling water.
3. Fry the Fish
Crispy tempura fish is the star of these tacos.
- Heat vegetable oil in a deep pan or fryer to 350°F (175°C). Use a thermometer for accuracy if possible.
- Pat the fish strips dry with paper towels to help the batter stick.
- Dip each strip into the batter, letting excess drip off, and carefully lower into the hot oil.
- Fry in small batches for 3–4 minutes, or until golden and crispy.
- Remove with a slotted spoon and place on a paper towel-lined plate to drain excess oil.
4. Assemble the Tacos
Now comes the fun part—putting it all together.
- Warm the tortillas in a dry skillet, directly over a gas flame, or in the oven until pliable.
- Place a few pieces of tempura fish in each tortilla.
- Add a generous spoonful of slaw.
- Garnish with fresh cilantro, avocado slices, or pickled jalapeños if desired.
- Serve immediately with lime wedges for squeezing over the top.
Tips for the Best Tempura Fish Tacos
- Keep the batter cold: Use ice-cold sparkling water and mix the batter just before frying. This ensures a light and airy coating.
- Work in small batches: Overcrowding the pan lowers the oil temperature, making the fish soggy. Fry only a few pieces at a time.
- Choose the right fish: Firm white fish like cod, tilapia, haddock, or halibut work best because they hold up to frying.
- Warm your tortillas: A quick toast enhances flavor and prevents them from breaking when filled.
- Balance flavors: The slaw provides freshness and acidity, balancing the richness of fried fish. Don’t skip it.
- Add a sauce: If you want more flavor, drizzle with spicy mayo, chipotle crema, or even a tangy yogurt sauce.
Serving Suggestions
Tempura fish tacos pair beautifully with a variety of sides and drinks. Consider serving them with:
- Mexican rice or cilantro-lime rice for a filling meal.
- Black beans or refried beans for extra protein.
- Fresh salsa or pico de gallo on the side.
- Margaritas, cold beer, or sparkling water with lime as refreshing drinks.
Variations to Try
- Spicy Kick: Add chili powder, cayenne, or smoked paprika to the batter.
- Tropical Twist: Top with pineapple salsa instead of slaw.
- Healthy Version: Bake or air-fry the fish instead of deep frying.
- Gluten-Free Option: Use rice flour instead of all-purpose flour in the batter.
Frequently Asked Questions
Can I use frozen fish for tempura tacos?
Yes, but thaw the fish completely and pat it very dry before battering. Excess moisture prevents crispiness.
Why does my tempura turn soggy?
This usually happens if the oil isn’t hot enough or if the batter is too warm. Keep the batter cold and fry at 350°F.
What tortillas are best—flour or corn?
Both work! Flour tortillas are softer and easier to fold, while corn tortillas provide a traditional flavor.
Can I make the slaw ahead of time?
Yes, but prepare it no more than 4 hours in advance for maximum crunch. Store it in the refrigerator until ready to serve.
How can I reheat leftover tempura fish?
Reheat in an oven or air fryer at 350°F (175°C) for a few minutes to restore crispiness. Avoid microwaving—it makes the coating soggy.
Can I substitute another protein?
Absolutely. Shrimp, chicken strips, or even tofu can be used with the same tempura batter.
