Italian Seafood Salad tastes bright, briny, and citrusy with tender shrimp, silky calamari, and meaty octopus. It suits holiday antipasto lovers and warm-weather cookouts, and the whole recipe takes about 45 minutes start to finish. I learned to squeeze an extra lemon from my Nonna-in-law, and it stuck.
Why This Italian Seafood Salad
Italian Seafood Salad comes together with quick poaching and a no-cook lemon garlic dressing. You use one pot, one bowl, and a handful of pantry staples. The seafood cooks fast, and the dressing ties everything together without fuss.
You can mix and match seafood based on what your market carries. Frozen, pre-cleaned shrimp and calamari work great, and pre-cooked octopus shaves off time. The salad tastes even better after a short rest, so you can prep ahead and take a victory lap later.
Ingredients You Need
- Shrimp, 1 pound, large 16-20, peeled and deveined (frozen works; thaw overnight in the fridge)
- Calamari, 1 pound, cleaned rings and tentacles (pre-cleaned rings save time)
- Cooked octopus, 1 pound, chopped bite-size (buy pre-cooked or simmer your own until tender)
- Mussels or littleneck clams, 1 pound, scrubbed and debearded if needed (vacuum-packed cooked mussels work in a pinch)
- Optional: scallops, 8 ounces, small bay scallops or quartered sea scallops
- Celery, 2 ribs, thinly sliced
- Red onion, 1 small, very thinly sliced (or sub shallot for a milder bite)
- Fennel bulb, 1 small, cored and shaved thin
- Roasted red pepper, 1 large, diced (jarred is perfect)
- Capers, 2 tablespoons, drained
- Castelvetrano or Gaeta olives, 1/2 cup, pitted and halved
- Flat-leaf parsley, 1/2 cup, chopped
- Lemon, 2 large, zested and juiced
- Red wine vinegar, 2 tablespoons
- Extra-virgin olive oil, 1/2 cup (a fruity Sicilian oil like Partanna tastes great, but use your favorite)
- Garlic, 3 to 4 cloves, finely minced
- Dried oregano, 1 teaspoon
- Red pepper flakes, 1/2 teaspoon, more to taste
- Kosher salt and black pepper
- Optional pinch of sugar to balance acidity
Equipment:
- Large pot for poaching and steaming

- Sharp knife, cutting board, paper towels, fine zester
How to Make Italian Seafood Salad
- Prep: 20 minutes
- Cook: 15 minutes
- Chill: 10 minutes
- Total: about 45 minutes
- Set up the basics: Fill a large bowl with ice water for an ice bath. Bring a large pot of well-salted water to a gentle simmer with 1 lemon half, a bay leaf, a few peppercorns, and parsley stems if you have them.
- Poach the shrimp: Slide in the shrimp and cook until just opaque, 1.5 to 2 minutes. Transfer to the ice bath to stop the cooking, then drain and pat dry.
- Poach the calamari: Add the calamari to the same pot and cook 45 to 60 seconds until just tender. Move to the ice bath, drain, and pat dry.
- Steam shellfish: In a clean pot with 1 cup water or dry white wine, steam mussels or clams over medium-high heat until they open, 3 to 5 minutes. Discard any that stay closed, remove the meat, and set aside.
- Prep octopus and optional scallops: Cut cooked octopus into bite-size pieces. If using scallops, poach them in the simmering water 1 to 2 minutes and chill, then pat dry.
- Mix the dressing: In a small jar or bowl, combine lemon zest and juice, red wine vinegar, garlic, oregano, red pepper flakes, 1 teaspoon kosher salt, and several grinds of black pepper. Whisk in olive oil until glossy. Taste and adjust with a pinch of sugar if the lemons run extra tart.
- Combine the salad: In a large bowl, add shrimp, calamari, octopus, mussels or clams, celery, red onion, fennel, roasted red pepper, capers, olives, and parsley. Pour over most of the dressing and toss gently to coat.
- Marinate and finish: Let the salad sit 15 to 30 minutes in the fridge. Toss again, add the remaining dressing if needed, and adjust salt, pepper, and lemon to taste.
- Plate and garnish: Mound onto a chilled platter. Drizzle a little more olive oil and sprinkle extra parsley for color.
Tips & Common Mistakes
- Salt the poaching water like the sea so your seafood tastes seasoned from within.
- Keep the water at a gentle simmer, not a rolling boil, to prevent rubbery texture.
- Cook seafood in batches and shock it in an ice bath to lock in tenderness.
- Pat everything dry before dressing so the vinaigrette clings instead of watering down.
- Cut seafood and veg into similar bite-size pieces for even flavor in every forkful.
- Dress while the seafood sits slightly warm to help it absorb flavor, then chill briefly.
- Zest the lemons before juicing so you do not lose that aroma.
- Taste chilled, then adjust salt and acid right before serving since cold mutes flavors.
- Use good olive oil; this salad leans on it for body and flavor.
- Do not over-marinate overnight with lots of acid or the proteins can firm up too much.
Variations I’ve Tried
- Citrus-herb: Add orange zest and segments, swap vinegar for more lemon, and fold in basil with parsley.
- Calabrian heat: Stir in 1 to 2 teaspoons Calabrian chili paste and a splash of the chili oil for a gentle burn.
- Ligurian vibes: Add toasted pine nuts and small cubes of boiled waxy potato with extra olives.
- Bean boost: Fold in 1 cup rinsed cannellini beans for extra protein and a creamy contrast.
- Grilled twist: Lightly grill the octopus and shrimp for smoky edges, then toss with the same dressing.
- No-shellfish version: Use shrimp, calamari, and octopus only, or swap in firm white fish cubes poached 1 to 2 minutes.
How to Serve Italian Seafood Salad
Serve it chilled or cool on a big platter as an antipasto, with lemon wedges and crusty bread to soak up the juices. Pair it with a crisp white wine like Vermentino or Pinot Grigio, or pour a spritzy Aperol Spritz if the sun feels generous. Add marinated artichokes, shaved Parm, and olives to round out the spread. For a light meal, spoon it over arugula with extra olive oil and a squeeze of lemon.
Make-Ahead and Storage
You can poach the seafood up to 24 hours ahead and chill it dry. Mix the dressing up to 3 days ahead and keep it in a sealed jar in the fridge, then shake before using. Store the dressed salad in the fridge for 2 to 3 days, and refresh with a touch of lemon and olive oil before serving. Skip freezing the finished salad since texture suffers; if you must freeze, freeze cooked octopus or shrimp separately and dress fresh later.
