This seafood pasta salad brings together shrimp, crab, and vibrant vegetables all tossed in a creamy lemon dressing. It’s a refreshing, easy-to-make dish that works perfectly for summer dinners or potlucks. The balance of flavors and textures makes it a favorite whenever I need a break from heavy meals or want something light yet satisfying. I first served this at a family barbecue last summer, and it quickly became the highlight of the meal.

Ingredients

  • Eight ounces of rotini penne or your favorite pasta shape: choose a sturdy pasta that will hold up well in the salad without getting mushy
  • One cup cooked shrimp peeled and ready: fresh cooked shrimp tastes best but frozen works fine, make sure to dry them well
  • One cup fresh crab meat checked for shells: fresh crab adds sweetness and a delicate texture
  • Half a cup chopped celery: adds crunch and freshness
  • Half a cup halved cherry tomatoes: for bursts of juicy sweetness
  • Quarter cup finely diced red onion: brings a mild sharpness that brightens the salad
  • Half a cup good quality mayonnaise: use full-fat for the best creamy mouthfeel
  • Two tablespoons fresh lemon juice: essential for brightness and balancing the richness of mayo
  • One tablespoon Dijon mustard: adds depth and subtle tang
  • Salt and freshly ground pepper to taste: enhances all the flavors
  • One tablespoon finely chopped fresh dill: a fragrant herb that complements seafood beautifully
  • Lemon wedges for serving: adds a fresh finishing touch when squeezed over the salad

My favorite ingredient is the fresh dill. Its herbal brightness brings the whole salad to life and pairs perfectly with seafood. This dish holds a special place in my family’s heart because it was the first thing we cooked together on a summer afternoon, creating wonderful memories as we shared the meal outdoors.

Storage tips

Store this salad in an airtight container in the refrigerator. It keeps well for up to two days though best eaten within that time for freshness. If it seems a bit dry after standing in the fridge you can stir in a little extra mayonnaise or a squeeze of fresh lemon juice before serving.

Ingredient substitutions

If you cannot find fresh crab use canned lump crab meat drained well. You can also swap the shrimp for cooked lobster or cooked scallops for a twist. For a lighter dressing substitute half the mayo with Greek yogurt.

Serving suggestions

Serve this salad chilled as a main for light lunches or dinners. It pairs beautifully with crusty bread or a crisp green salad. A cold glass of white wine or sparkling water with lemon is a refreshing pairing.
