Fish Tacos with Easy Coriander Hot Sauce

Fish ‘Tacos’ with Easy Coriander Hot Sauce

I’m calling these ‘tacos’ because I’ve used lettuce leaves instead of tortillas. But don’t let that put you off.

They’re super delicious and with the fresh zesty hot sauce your taste buds will be happy!

If you’re using the lettuce leaves it’s a pretty light meal. So see the more substantial options below if you’re feeling hungry.

While this hot sauce is amazing here with fish, I also love it with chicken or pork or anything with avocado.

Total Time 20 minutes
Servings 2


  • 1 bunch coriander (cilantro)
  • 1-2 red chilli peppers
  • 2 tablespoons lime juice
  • 2 fish fillets each sliced into 3 long fingers
  • 2 medium zucchini grated
  • 6 cos lettuce leaves or zucchini tortillas to serve


  1. For the sauce, chop coriander (cilantro) leaves and stems coarsely. Place in a tall jug or wide mouthed jar large enough to fit your stick blender. Add chilli, 4 tablespoons extra virgin olive oil and lime juice. Blitz using your stick blender until you have a pureed vibrant green sauce. If you don’t have a stick blender, use a food processor, regular blender of chop everything by hand.
  2. Heat a medium frying pan on a medium high heat. Season fish with a pinch of salt. Add a splash of oil to the pan and cook fish for 2-4 minutes on each side or until browned and cooked through.

Variations & Substitutions

taco bowls – serve shredded lettuce and grated zucchini in two bowls then top with hot fish and the green sauce.

short on time – use a commercial hot sauce instead.

vegetarian – fish = pan fried halloumi cheese or fried eggs.

more substantial (carb lovers) – warm tortillas or flat bread.

more substantial (low carb) – serve with mayo, sour cream, avocado, peanuts, almonds or roast cashews. Using the zucchini tortillas makes it much more filling than the lettuce leaves.

family friendly – skip the chilli pepper.

different herbs – basil or parsley.

carnivore – pork fillet, pork sausages, chicken thigh fillets are all lovely with the sauce.

no lime – use lemon juice.

crispy fish – dust fish with almond meal or another flour before pan frying.

Waste Avoidance Strategy

coriander – best to use for another meal. Can be frozen but will wilt when defrosted.

red chillies – will keep for months in the fridge. Can be frozen or left unwrapped in the fridge they will slowly turn into dried chillies and still be edible.

lime – will keep in a plastic bag in the fridge for months.

fish fillets – freeze the fillets alone or you could make the fish cakes and freeze the mixture ready to defrost and cook.

zucchini – will keep for 2 weeks or longer in a plastic bag in the fridge. To keep it even longer, cook sliced zucchini in a little butter until just soft then store in an airtight container in the fridge.

lettuce – will keep in the fridge for a few weeks in a plastic bag. Otherwise use for another meal as it’s not great once frozen.

zucchini tortillas – freeze them.

Prepare Ahead

No. Everything is best when freshly made! Leftovers will keep in the fridge for up to a week. Don’t freeze.
