Ingredients

Instructions

  1. Step 1: Pat dry 1 lb white fish fillets and coat evenly with 2 tbsp Cajun seasoning on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the seasoned fish and cook for 3-4 minutes per side until blackened and cooked through, flaking easily with a fork.
  3. Step 3: In a mixing bowl, combine 1 large diced mango, 1/2 diced red bell pepper, 1/4 cup finely chopped red onion, 3 tbsp chopped cilantro, 2 tbsp lime juice, 1/2 tsp salt, and 1/4 tsp black pepper. Toss gently to make mango salsa.
  4. Step 4: Warm 8 corn tortillas in a dry skillet or microwave until pliable.
  5. Step 5: Assemble tacos by placing pieces of the blackened fish into each tortilla, topping with a generous spoonful of mango salsa, and a dollop of 1/2 cup sour cream. Add hot sauce if desired and serve immediately.

How do I scale Cajun-Spiced Blackened Fish Tacos with Mango Salsa for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
