Classic Seafood Salad Recipe: Crisp Celery Crowns and Zesty Lemon-Dill Dressing

This classic seafood salad recipe delivers the perfect balance of fresh seafood, crisp vegetables, and a bright lemon-dill dressing that's become a staple at my dinner table. The secret lies in chilling the salad for at least 30 minutes before serving—this allows flavors to meld and the celery to develop that signature crispness that makes every bite satisfying. I've perfected this version over years of testing, ensuring the shrimp stays tender, the crab stays sweet, and the dressing doesn't overpower the delicate seafood flavors.

The foundation of this salad is a simple yet effective technique: layering the ingredients in the right order. Start with the heartier elements—like crisp celery and avocado—then add the seafood on top, reserving the dressing until just before serving.

This keeps everything fresh and prevents sogginess. The dressing itself is where the magic happens—a zesty lemon-dill combination with just enough mayonnaise to bind everything together without making it heavy.

What you'll end up with is a salad that's elegant enough for a dinner party but simple enough for a weeknight lunch. The shrimp and crab maintain their natural sweetness, the celery stays crisp, and the dressing adds a bright, herby finish that cuts through the richness of the seafood.

The texture contrast—crisp, creamy, and tender—makes every bite exciting.

Serve this salad on its own or pair it with crusty bread and a glass of chilled white wine. The flavors improve as it sits, so making it ahead of time is a smart move. Here's how to assemble it perfectly every time.

Ingredients for classic seafood salad

Six ingredients for the seafood base, five for the dressing, plus crisp lettuce to hold it all together.

The seafood quality makes or breaks this salad. Seafood counters at Whole Foods or local fish markets are your best bet for freshness—look for shrimp with a translucent sheen and crab that smells briny, not fishy. Trader Joe's often has pre-picked lump crab at a great price, but if you're using frozen, thaw it overnight in the fridge. Celery should be rock-hard with no browning at the base; store-bought bags often have softer stalks, so grab a bunch from the produce section. The avocados need to be ripe but not mushy—press gently, and if they yield slightly, they're perfect. For dill, fresh is non-negotiable here; dried just won't cut it.

No lump crab? Chopped cooked shrimp or imitation crab works in a pinch, though texture will differ. Short on fresh dill? Dried dill at one-third the amount can substitute, but add it to the dressing just before tossing. The mayo can be light or Greek-style, but full-fat gives the best texture. For a lighter version, reduce it to 0.25 cup and add 1 tbsp Greek yogurt. Lemon juice should be freshly squeezed—bottled just won't have the same zing. If you're prepping ahead, hold off on adding the dressing until serving to keep everything crisp. The red onion can be swapped for green onion or shallots if you prefer milder flavor.

This salad tastes even better the next day—make it ahead and refrigerate for up to 2 days. The shrimp and crab stay tender, and the celery maintains its crispness if you pat it dry thoroughly before adding to the salad. For longer storage, freeze the seafood and dressing separately—combine only when ready to serve. The dressing keeps for 5 days in the fridge, so make extra for sandwiches or wraps. Lettuce should be wrapped in a damp paper towel and stored in a sealed container to stay crisp. Serve chilled, and add a sprinkle of fresh dill right before eating for maximum freshness.

Step-by-step instructions for classic seafood salad

This method delivers a restaurant-quality seafood salad with crisp celery crowns and a bright, balanced dressing.

Start by peeling and deveining the 1.5 lb fresh shrimp, leaving the tails intact for presentation. Pat them completely dry with paper towels to ensure they cook evenly. In a medium saucepan, bring 2 cups of water to a gentle boil—just enough to maintain a simmer, not a rolling boil. Add the shrimp and cook for 2-3 minutes until they turn opaque pink and curl slightly. Immediately transfer them to an ice bath to stop the cooking process and lock in their tenderness.

While the shrimp chills, pick through the 1.5 cups lump crab meat to remove any remaining shells or debris. Place it in a medium bowl and set aside. The crab should be cool to the touch before combining with other ingredients to prevent the mayonnaise from breaking later.

Cut the 3 whole celery stalks into ½-inch thick slices, keeping them whole like crowns. Blanch the celery in boiling water for 30 seconds, then immediately transfer to an ice bath again. This brief cooking step softens the celery while maintaining its crisp texture. Drain well and pat dry with paper towels.

Core the 1 head iceberg lettuce and separate the leaves. Wash them thoroughly and dry completely to prevent a soggy salad. Arrange the lettuce leaves on a large platter to form the salad base. The crisp texture of the iceberg will provide the perfect contrast to the rich seafood components.

In a small bowl, whisk together the 0.5 cup mayonnaise, 0.5 cup lemon juice, 0.25 cup extra-virgin olive oil, 1 tbsp fresh lemon zest, 1 tsp salt, and 0.5 tsp black pepper. The dressing should be smooth and well-emulsified. Add the 0.25 cup chopped fresh dill and mix gently to preserve its texture.

Taste the dressing and adjust the seasoning if needed. The lemon zest adds a bright citrus note that complements the richness of the seafood, while the dill provides a fresh herbal element. This dressing is the heart of the salad, binding all the components together with its zesty flavor profile.

Gently fold the cooked shrimp and crab meat into the dressing, coating them evenly. Add the 0.5 cup finely diced red onion and 2 diced whole avocados to the mixture. The avocados should be ripe but firm enough to hold their shape. Fold everything together just until combined—avoid overmixing to maintain the texture of the seafood and avocado.

Spoon the seafood mixture onto the prepared lettuce leaves, arranging the celery crowns around the edges for a decorative touch. The crisp celery crowns will add a satisfying crunch with each bite, while the creamy avocado and tender seafood provide a luxurious texture.

Transfer the seafood salad to a serving platter and garnish with additional chopped fresh dill and a sprinkle of freshly cracked black pepper. Serve immediately while the avocado is still firm and the dressing is vibrant. This salad is best enjoyed fresh, as the flavors and textures are at their peak right after assembly.

For an elevated presentation, arrange the salad on a large platter with the celery crowns fanned out around the edges. The contrast between the crisp lettuce, creamy avocado, tender seafood, and crunchy celery creates a harmonious bite that captures the essence of a classic seafood salad.

Serving suggestions for this recipe

Crisp Presentation

Arrange the salad on a large platter with the iceberg lettuce leaves forming a circular base. Spoon the seafood mixture in the center, then fan the blanched celery crowns around the edges for a decorative touch.

I like to use a wooden salad server to gently transfer the salad to plates, keeping everything intact. 🥗

Garnish Like a Pro

Add a final sprinkle of chopped fresh dill and a pinch of freshly cracked black pepper right before serving. For extra flair, I drizzle a thin line of extra-virgin olive oil around the edges or add a few lemon zest curls on top.

These finishing touches elevate the dish from homemade to restaurant-worthy.

Bread Pairings

Serve with crusty sourdough bread or baguette slices for dipping. I recommend toasting the bread lightly and brushing it with garlic-infused olive oil before serving. The bread soaks up any extra dressing beautifully while adding a satisfying crunch. 🍞

Wine & Beverage

A crisp Sauvignon Blanc or Chardonnay complements the bright lemon-dill flavors perfectly. For a non-alcoholic option, try sparkling lemonade or iced hibiscus tea—both enhance the citrus notes. I also love pairing this salad with a light lager like Peroni for a refreshing contrast.

Make-Ahead Serving

Assemble the salad up to 4 hours ahead and store it in an airtight container in the fridge. Keep the dressing separate until serving to maintain crispness. When ready to serve, simply toss the salad with the dressing and garnish.

This makes it perfect for potlucks or dinner parties where you need to prepare ahead. ⏰

Seasonal Variations

In summer, add sliced heirloom tomatoes and cucumber ribbons for extra freshness. For winter, swap the lettuce for arugula and add roasted butternut squash cubes. I also love adding pomegranate seeds in fall for a pop of color and sweetness.
