Instructions
- Prep and Season the Fish:
- Pat fish fillets completely dry with paper towels to ensure the seasoning sticks. Brush with olive oil thoroughly on both sides to create a protective layer that prevents sticking and helps the exterior get a little crispy on the grill. Mix together chili powder paprika garlic powder and cumin in a small bowl sprinkle generously over both sides of the fish fillets and finish with salt and pepper. Press the spices on gently for even coverage.
- Mix the Spicy Mayo:
- In a small bowl combine mayonnaise sriracha and lime juice. Stir until smooth and well blended. Taste a little sauce and adjust sriracha for more or less heat as you like. Cover and refrigerate while you finish the other steps this helps the flavors meld.
- Make the Pico de Gallo:
- Dice Roma tomatoes finely chop red onion and fresh cilantro and mince jalapeño if you are using it for extra spice. Put everything into a mixing bowl sprinkle with a pinch of salt then add lime juice. Stir gently to combine and set aside at room temperature this lets the flavors mingle and the tomatoes release a bit of their moisture.
- Grill the Fish:
- Preheat your grill or grill pan to medium-high heat. Coat the grates with a little oil if needed to prevent sticking. Lay the seasoned fish fillets directly on the grill. Cook for three to four minutes on the first side without moving the fish to allow grill marks to form and to build a light char. Flip carefully with a wide spatula and finish grilling another three to four minutes until the fish flakes easily and is just cooked through.
- Warm the Tortillas:
- Set corn tortillas directly on the grill for thirty seconds per side to soften and give a hint of smoky flavor. Wrap in a clean kitchen towel to keep them warm while assembling tacos.
- Assemble and Serve:
- Gently flake the grilled fish into chunky pieces with a fork. Fill each warm tortilla with a portion of fish drizzle over a generous amount of spicy mayo and pile on a spoonful of pico de gallo. Serve right away with lime wedges on the side for squeezing.
Save I always look forward to that first juicy bite with a squeeze of lime the cilantro and charred fish bring me right back to family barbecues on lazy summer evenings. I love watching my kids build their tacos just the way they like them.
Storage Tips
Store leftover fish flaked in an airtight container for up to two days in the fridge. Pico de gallo keeps best for a day and should be drained of excess liquid before storing. Warm tortillas taste best fresh but can be wrapped in foil and reheated in a low oven for a few minutes.
Ingredient Substitutions
Use any mild firm white fish you prefer and try swapping Greek yogurt for mayonnaise for a lighter spicy mayo. If sriracha is unavailable blend hot sauce with a pinch of sugar. Flour tortillas also work in place of corn if you prefer a softer bite.
Serving Suggestions
Serve these tacos with fresh lime wedges shredded cabbage or avocado slices for extra texture. Pair with quick cilantro rice a crisp salad or grilled corn for a perfect taco night spread.
Cultural and Historical Context
Fish tacos originated in the coastal areas of Mexico especially Baja California where freshly caught seafood and handmade tortillas are key. Traditional versions often feature battered fish but grilling offers a lighter twist that lets the spices and toppings shine.
Seasonal Adaptations
Use grilled zucchini or roasted peppers as a vegetarian option
Try mango for a sweet twist in the pico de gallo during late summer
In winter pan-sear the fish indoors if grilling is not possible
