Ingredients (serves 1–2)
- 300 g fish fillet (e.g. tilapia or sea bream)
- 2 large onions
- 2 cloves of garlic
- 1 lemon (juice and zest)
- 2 tablespoons olive oil
- 1 teaspoon mustard
- 1 teaspoon paprika
- Salt and pepper to taste
- Fresh coriander, to garnish
Shopping for the ingredients
When shopping for the ingredients for Poisson Yassa, it pays to pick the freshest produce you can find. The fish should be as fresh as possible to bring out the best flavour — glossy skin and a mild, clean smell are good signs of freshness. The onions and lemon should be firm and unblemished too, so the dish keeps its full, rounded taste.
Preparing the dish
Good preparation is the key to a successful Poisson Yassa. Start by cutting the fish into even pieces so it cooks through uniformly. Next, make the marinade by slicing the onions into thin rings and mixing them with lemon juice, garlic, mustard, paprika, salt and pepper. Leave the fish to sit in this mixture for at least 30 minutes so it can soak up all the aromas.
Step-by-step instructions
- Place the fish fillets in a bowl and pour the prepared marinade over them.
- Leave to marinate for at least 30 minutes, ideally in the fridge.
- Heat the olive oil in a large pan and add the onion rings.
- Fry the onions until golden brown, then lay the fish in the pan.
- Cook the fish for 5–7 minutes per side, until it is cooked through.
- Garnish with fresh coriander and serve warm.
Gluten-free / lactose-free version
The recipe for Poisson Yassa is naturally gluten-free and lactose-free. You can follow the method exactly as written without altering any of the ingredients. The marinade and the main components make the dish suitable for anyone with particular dietary needs. Enjoy it with complete peace of mind while you savour all the aromas and the delicate texture of the fish.
Tips for vegans and vegetarians
For a vegan version of Poisson Yassa, swap the fish for smoked tofu or tempeh. Marinate the tofu pieces just as you would in the original recipe, then pan-fry them until golden. Vegetables such as aubergine or courgette can also step in for the fish and give the dish a lovely character of their own. That way the meal stays every bit as tasty and aromatic while turning fully plant-based.
More tips and tricks
One easy trick to make Poisson Yassa even more flavourful is to add a little chilli or more of your favourite spices. Experiment with different ingredients to tune the dish to your own taste. Remember that you can brown the onions for longer to coax out a sweeter note. A side of rice or Couscous also works beautifully with the lemony sauce and the fish.
Adapting the recipe to your taste
A great advantage of Poisson Yassa is how easily it adapts. You can try different kinds of fish depending on what is available or what you prefer. You can also vary the marinade by adding herbs and spices of your choosing. The combination with Mediterranean flavours is especially appealing and lends the dish a unique twist.
Ingredient substitutions
If you happen to be missing certain ingredients for Poisson Yassa, there are plenty of alternatives. Instead of fresh fish you can use frozen fillets, which are a good option when fresh fish is hard to come by — the same approach works nicely for a Poisson Braise. For the marinade, another vegetable oil can stand in for the olive oil, and the lemon can even be replaced with lime for a different but equally delicious note.
Drink pairing ideas
Several drinks pair well with a flavourful Poisson Yassa. A fresh, zippy white wine such as a Sauvignon Blanc complements the citrus notes of the dish perfectly. Alternatively, you might serve a refreshing non-alcoholic drink like lemonade or sparkling water with lemon. For an exotic touch, a cocktail with pineapple or mango is an excellent choice that rounds off the whole experience.
Serving and presentation ideas
To present Poisson Yassa attractively to your guests, use handsome plates and garnish the dish with fresh coriander. You can also arrange lemon slices around the fish to add colour and a sense of freshness. Serve everything on a large platter so each guest can help themselves. A small extra dish of the marinade offered as a dip rounds off the presentation perfectly.
A bit of history

The preparation of fish reflects the coastal traditions of the region, while the use of onions and citrus mirrors the area’s varied agricultural produce.
