Ingredients
For the Blackened Fish
- 4 white fish fillets (cod, mahi-mahi, or tilapia work great)
- 2 tbsp olive oil
- 1 tbsp smoked paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp cayenne pepper (adjust to taste)
- 1 tsp dried oregano
- 1/2 tsp cumin
- Salt and black pepper to taste
For the Mango Slaw
- 2 cups shredded cabbage (green or purple, or a mix)
- 1 ripe mango, julienned
- 1/4 cup chopped cilantro
- Juice of 1 lime
- 1 tbsp honey
- 1 tbsp olive oil
- Pinch of salt
For the Elote Salad
- 3 cups corn kernels (fresh, grilled if possible)
- 1/4 cup mayonnaise
- 1/4 cup crumbled cotija cheese
- 1 tsp chili powder
- Juice of 1 lime
- 2 tbsp chopped cilantro
To Serve
- Small flour or corn tortillas
- Extra lime wedges
- Hot sauce, optional
Instructions
- Season the fish. In a small bowl, mix the smoked paprika, garlic powder, onion powder, cayenne, oregano, cumin, salt, and pepper. Pat the fish dry, brush with olive oil, then coat evenly with the spice mix on both sides.
- Cook the fish. Heat a cast iron skillet or grill pan over medium-high heat. Once hot, sear the fish for 3–4 minutes per side, until it flakes easily and has a deep, blackened crust. Set aside and let rest for a couple of minutes, then flake into large pieces.
- Make the mango slaw. In a large bowl, toss the cabbage, mango, and cilantro. Whisk together the lime juice, honey, and olive oil, then pour over the slaw. Toss well and season with a pinch of salt.
- Make the elote salad. If using fresh corn, grill or char it in a hot pan for a few minutes until it gets some color. In a bowl, mix the corn with mayonnaise, cotija, chili powder, lime juice, and cilantro until well combined.
- Warm the tortillas. Heat them briefly in a dry skillet or directly over a flame until soft and slightly charred at the edges.
- Assemble. Fill each tortilla with a generous scoop of blackened fish, top with mango slaw, and serve the elote salad on the side. Finish with extra lime wedges and hot sauce if you like it spicy.
Tips for the Best Fish Tacos
- Don’t overcook the fish — it should still be moist and flaky, not dry. 3–4 minutes per side is usually enough depending on thickness.
- Make the slaw ahead — it actually tastes better after sitting 15–20 minutes, letting the flavors meld.
- Char your corn — grilling or pan-charring the corn for the elote salad adds a smoky depth that raw corn just can’t match.
- Double the spice mix — it keeps well in a jar and is great on shrimp, chicken, or roasted veggies too.
What to Serve With It
This meal is a complete summer plate on its own, but if you want to round it out, try serving with a side of black beans, a pitcher of agua fresca, or a simple avocado salad.
