A one-pot Seafood recipe with Mexican flavors, built for busy weeknights when you want real food without a sink full of dishes. Comes together in roughly 49 minutes, serves about 4, and uses ingredients you can find at any normal grocery store. The technique is simple: build a base in your pot, layer in the main ingredients, simmer until everything has had time to talk to each other, and serve straight from the pan. If you're cooking for picky eaters, this one tends to land — the flavors are recognizable, the texture is comforting, and there's nothing weird hiding in the ingredient list. Perfect for the kind of evening where you want dinner on the table by 7pm and the kitchen empty by 7:30.

Ingredients

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
4 shredded Spring Onions
1 x 300ml Salsa
1 pot Sour Cream
1 Lemon
1 clove finely chopped Garlic

Step-by-step instructions

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.
On a large plate, mix the cajun spice and cayenne pepper with a little seasoning and use to coat the fish all over.
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.
Meanwhile, prepare the dressing by combining all the ingredients with a little seasoning.
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.

Why this works on a weeknight

Cajun spiced fish tacos lands at about 31 minutes total — a little longer than our 30-minute target, but most of that time is hands-off simmering, which is why it earned a spot in our Skillet & One-Pan collection. The technique is forgiving, the ingredient list is grocery-store standard, and the active cooking time is short enough that you can answer a text message in the middle without ruining dinner.

Cleanup notes

This is a single-pan recipe, so the cleanup is exactly one pan, one cutting board, and one knife. While the dish rests, fill the pan with hot soapy water — by the time you are done eating, the residue lifts off with a single pass of a sponge. Skip the steel wool on cast iron; a stiff brush and warm water are all you need to keep the seasoning intact.

Make-ahead and leftovers

Leftovers keep covered in the fridge for up to three days. Reheat in a dry pan over medium-low with a splash of water or stock to loosen the sauce. Cajun spiced fish tacos actually improves overnight as the flavors keep talking to each other, so doubling the recipe and packing tomorrow's lunch is a high-leverage weeknight move.
