Instructions
-
Boil the lobsters. Bring a large pot of heavily salted water to a rolling boil. Tie each lobster's claws with kitchen twine to prevent them from flailing. Plunge the lobsters headfirst into the water. Cover and cook for 15 to 20 minutes, depending on size. The shell should be bright red and the tail meat opaque.
Tip: Use about 1 tablespoon of coarse salt per liter of water. The water should taste like the sea. A heavily salted cooking liquid seasons the meat from the outside in. -
Cool and shell the lobsters. Remove the lobsters from the pot and let them rest until cool enough to handle. Twist off the claws and crack them open. Cut the tail section from the body. Use scissors to snip along the underside of the tail shell and remove the meat in one piece. Peel away the membrane. Cut the tail meat crosswise into medallions about 1.5 cm thick. Crack the claws and remove the meat whole.
Tip: Work while the lobster is still warm. The meat separates from the shell more easily when it has not fully cooled. Keep the claw meat intact for presentation. -
Prep the vegetables. Halve the cherry tomatoes. Thinly slice the red onion into rounds. Cut the carrots into thin julienne sticks. Slice the celery thinly on the bias. Cut both bell peppers into strips. Separate the endive leaves. Slice the radishes into thin rounds. Thinly slice the spring onions.
Tip: Cut everything as thinly and evenly as you can. The vegetables should be fine enough to eat comfortably alongside the lobster without needing a knife. -
Make the vinaigrette. In a small bowl, whisk together the Dijon mustard, white wine vinegar, and lemon juice. Slowly drizzle in the olive oil while whisking constantly to emulsify. Season with salt and a generous amount of black pepper.
Tip: The mustard acts as the emulsifier. Add the oil in a very thin stream and keep whisking. The dressing should be thick enough to coat the back of a spoon. -
Assemble the salad. Arrange the sliced vegetables on a large serving platter or individual plates. Scatter the cherry tomatoes, radishes, and spring onion over the top. Lay the warm lobster medallions and claw meat over the vegetables.
-
Dress and serve. Spoon the vinaigrette over the lobster and vegetables. Serve immediately while the lobster is still warm. The contrast between the warm meat and the cold, crisp vegetables is the point of the dish.
Storage & Meal Prep
This dish is best served immediately while the lobster is still warm. If you need to prepare ahead, cook and shell the lobsters up to 4 hours in advance, then reassemble just before serving. The dressed vegetables can sit for up to 30 minutes without wilting.
Variations
- Simple Version: Skip the full vegetable bed and serve the lobster simply with sliced red onion and cherry tomatoes dressed with olive oil, lemon, and salt. This is the everyday Alghero version.
- With Boiled Potatoes: Add 300g of boiled waxy potatoes cut into chunks for a more substantial dish. In some Alghero households this turns the salad into a light main course.
- With Capers and Olives: Add 1 tablespoon of rinsed capers and a handful of Taggiasca olives to the vegetable bed for a brinier, more complex flavor.
FAQ
What is aragosta alla catalana?
Aragosta alla catalana is a boiled lobster salad from Alghero, on the northwest coast of Sardinia. The city has strong Catalan roots, and this dish reflects that heritage: boiled lobster served warm over a bed of finely cut raw vegetables with a sharp vinaigrette. It is one of the most celebrated dishes on the Alghero table.
How do you humanely kill a lobster before boiling?
Place the lobster in the freezer for 30 minutes to sedate it, then split it lengthwise with a heavy knife through the head. This is the fastest method. Alternatively, some cooks plunge the live lobster directly into rapidly boiling salted water, which kills it almost instantly.
Can I use frozen lobster tails?
Yes, but the result will be different. Whole lobster gives you the claw meat and the roe, which are part of the dish. If using tails only, boil them for 8 to 10 minutes and skip the splitting step. The flavor will be cleaner but less complex.
Why is it called 'catalana'?
Alghero was a Catalan colony for centuries, and its cuisine carries clear Catalan markers. The combination of boiled seafood with raw vegetables and a sharp oil-and-vinegar dressing follows a pattern found across Catalan cooking. The name refers to this shared heritage rather than a specific technique.
What wine pairs with this?
A cold Vermentino from northern Sardinia is the traditional pairing. The wine's acidity and slight bitterness match the lemon vinaigrette and cut through the richness of the lobster. A dry Catalan Cava also works well.

The Story Behind This Dish
Aragosta alla catalana is one of the signature dishes of Alghero, the Catalan-speaking city on Sardinia’s northwest coast. It is a deceptively simple preparation: boiled lobster, served warm, laid over a bed of finely cut raw vegetables and dressed with a sharp vinaigrette. The dish is all about the contrast between the sweet, warm lobster meat and the cold, crunchy vegetables beneath it.
In Alghero this appears on every seafood restaurant menu and at every holiday table. The version I know best is the one with the full vegetable bed: carrots, celery, endive, radishes, bell peppers, spring onion, and cherry tomatoes, all cut thin and arranged so that every forkful has a bit of lobster and a bit of crunch.
Why this works
- Boiling, not grilling. The traditional Alghero method is to boil the lobster in heavily salted water. This keeps the meat tender and sweet. Grilling adds smokiness but dries out the delicate tail meat.
- Warm lobster, cold vegetables. The temperature contrast is deliberate. The warm meat releases its juices into the dressing, which then coats the cold vegetables. Serve it at room temperature and the dish falls flat.
- A sharp vinaigrette. The mustard and white wine vinegar give the dressing enough acidity to cut through the richness of the lobster without masking its flavor. Lemon juice adds brightness.
A note on buying lobster
Buy live lobsters from a fishmonger you trust. They should be active, with their tails curling when picked up. The most common size for this dish is 500 to 600 grams each. Two lobsters of this size will serve four as a starter. If you can only find frozen tails, the dish still works, but you lose the claw meat and the roe, which are part of what makes the full version special.
Serving
This is an antipasto or a light second course. In Alghero it often opens a seafood meal alongside marinated anchovies or a bowl of spaghetti with clams. A cold Vermentino from northern Sardinia is the standard pairing.
