About Carapau Grelhado
Carapau Grelhado is a traditional speciality from Portugal that delights anyone with a love of seafood. The grilled horse mackerel is enjoyed all along the Atlantic coast and stands as a symbol of Portuguese food culture. The dish unites the fresh taste of the sea with the aromatic warmth of herbs and seasoning. It is perfect for hot summer days or relaxed evenings spent in good company, and it shows off the country’s love of cooking the catch as plainly and honestly as possible.
Ingredients (serves 1–2)
- 2 fresh horse mackerel (about 300–400 g)
- 2–3 tablespoons olive oil
- Juice of 1 lemon
- 1 teaspoon coarse salt
- Pepper, to taste
- Fresh herbs (such as parsley or coriander)
Shopping for the ingredients
For the perfect Carapau Grelhado, it is worth seeking out the freshest ingredients you can find. Visit your local fishmonger or fish market to buy the horse mackerel at its best. Look for fish with clear, bright eyes and firm flesh — sure signs of freshness. The remaining ingredients, especially the fresh herbs, should also be bought as fresh as possible to deepen the flavour of the finished dish.
Preparing the dish
Before you begin cooking, the horse mackerel should be cleaned and gutted with care. You can ask your fishmonger to do this for you, or tackle it yourself if you feel confident. Pat the fish thoroughly dry afterwards so it picks up an attractive, charred pattern on the grill. Have the seasoning and olive oil ready in advance to save time once the grill is hot.
Step-by-step instructions
- Clean the horse mackerel thoroughly and season inside and out with salt and pepper.
- A few minutes before grilling, mix the olive oil with the lemon juice and brush it over the fish to marinate.
- Preheat the grill and lay the fish on the hot bars.
- Grill the fish for roughly 4–6 minutes per side, depending on thickness, until golden and crisp.
- Once cooked, scatter with fresh herbs and serve with lemon wedges.

Tips for vegans and vegetarians
Carapau Grelhado cannot be recreated exactly without fish, but there are some excellent alternatives for vegans and vegetarians. In place of the mackerel, try grilling vegetables such as courgettes or aubergines, which take wonderfully to the same marinade. You can also experiment with plant-based proteins like tofu or tempeh, which offer a similar firm, satisfying texture once grilled.
More tips and tricks
For the perfect Carapau Grelhado, make sure the grill is well and truly hot before the fish goes on. A hot grill stops the fish from sticking and gives it those handsome char marks. When it is time to turn the fish, use a wide pair of grill tongs to avoid tearing the flesh. It also helps to grill the skin side first, as this keeps the fish together and holds its shape.
Adapting the recipe to your taste
The recipe is easy to adapt to your own preferences. Add extra spices such as paprika or chilli for a warmer, fierier note. Alternatively, fold Mediterranean herbs like basil or oregano into the marinade to take the dish in a fresh direction. Be playful and try out whatever appeals to you most — the simplicity of grilled fish leaves plenty of room to experiment.
Ingredient substitutions
Depending on what is available or what you fancy, you can vary the ingredients for your Carapau Grelhado. Instead of horse mackerel, sardines or trout also grill beautifully — much like the Frango de Churrasco that thrives over the same coals. With the herbs you can experiment freely: thyme or rosemary lend their own intriguing aromas. Stay open to substitutions to keep your grilled dishes interesting.
Drink pairing ideas
A light, refreshing wine is the natural partner for Carapau Grelhado. A good Portuguese Vinho Verde sits in perfect harmony with the flavour of the fish. A cool, pale lager makes a fine match too, echoing the dish’s fresh, briny character. For alcohol-free options, reach for sparkling water with a slice of lemon or a fruity smoothie — a far gentler companion than a warming Mulled Wine with Spices.
Serving and presentation ideas
Presentation matters with a dish like Carapau Grelhado. Serve the fish on a handsome plate, garnished with fresh herbs and lemon. Add a side such as a colourful salad or a tumble of grilled vegetables to bring the plate to life. A thoughtful presentation not only whets the appetite but is sure to impress your guests as well.
A bit of history
The tradition of grilling fish runs deep in Portugal, above all along its long coastline — a thread that connects this dish to coastal classics like Caldeirada de Peixe. Carapau is a much-loved fish, native to the surrounding waters and a regular feature of regional cooking. Its simple preparation and reliance on fresh ingredients sit at the very heart of Portuguese cuisine. The dish reflects the Portuguese love of the sea and a rich culinary heritage that prizes letting good produce speak for itself.
