Cajun spiced fish tacos

Ingredients

Servings:
4
  • 2 tbsp cajun
  • 1 tsp cayenne pepper
  • 4 fillets white fish
  • 1 tsp vegetable oil
  • 8 flour tortilla
  • 1 sliced avocado
  • 2 shredded little gem lettuce

  • 1 pot sour cream
  • 1 lemon
  • 1 clove finely chopped garlic

Instructions

5 steps · ~28 minutes total

  1. Step 1

    Cooking in a cajun spice and cayenne pepper marinade makes this fish super succulent and flavoursome. Top with a zesty dressing and serve in a tortilla for a quick, fuss-free main that's delightfully summery.

    2 minutes
    For best results, marinate in the refrigerator for at least 30 minutes.
  2. Step 2

    On a large plate, mix the cajun spice and cayenne pepper with a little seasoning and use to coat the fish all over.

    3 minutes
    Taste as you go and adjust seasoning gradually — you can always add more but can't take it away.
  3. Step 3

    Heat a little oil in a frying pan, add in the fish and cook over a medium heat until golden. Reduce the heat and continue frying until the fish is cooked through, about 10 minutes. Cook in batches if you don’t have enough room in the pan.

    8 minutes
    Test the oil temperature with a small piece of food — it should sizzle immediately.
  4. Step 4

    Meanwhile, prepare the dressing by combining all the ingredients with a little seasoning.

    5 minutes
    Taste as you go and adjust seasoning gradually — you can always add more but can't take it away.
  5. Step 5

    Soften the tortillas by heating in the microwave for 5-10 seconds. Pile high with the avocado, lettuce and spring onion, add a spoonful of salsa, top with large flakes of fish and drizzle over the dressing.

    10 minutes
    A pinch of salt helps onions soften faster and release their natural sweetness.
