This seafood pasta salad combines tender pasta with fresh shrimp and crab, all tied together in a creamy, tangy dressing. It’s perfect for a light lunch or a side dish at a summer gathering. The mix of textures and flavors always makes it a crowd-pleaser in my house.
I first made this for a beach picnic and the fresh lemon and dill made it feel so bright and refreshing. Now it’s a frequent request from friends and family.
Ingredients
- Pasta: such as rotini or penne, cooked al dente for a nice bite
- Cooked shrimp: peeled and ready to go for easy mixing
- Fresh crab meat: checked carefully for shells to keep every bite smooth
- Celery: chopped small to add a crisp freshness
- Cherry tomatoes: halved for bursts of sweetness
- Red onion: finely diced for that gentle sharpness
- Good quality mayonnaise: to create that creamy base
- Fresh lemon juice: to add brightness and balance the richness
- Dijon mustard: gives a subtle tang and depth to the dressing
- Salt and freshly ground pepper: to taste enhancing all the flavors
- Fresh dill: chopped to lend a lovely herbal note
- Lemon wedges: for serving that extra zesty finish
Step-by-Step Instructions
- Cook the Pasta:
- Prepare pasta according to the package directions until al dente. Drain thoroughly then rinse with cold water to stop cooking and cool it down. This step keeps the pasta from becoming mushy and helps the salad stay fresh.
- Combine the Main Ingredients:
- In a large bowl, gently mix the cooled pasta with shrimp, crab meat, celery, cherry tomatoes, and red onion. Toss carefully so the seafood stays intact and all the components are evenly distributed.
- Make the Dressing:
- In a separate bowl, whisk together mayonnaise, lemon juice, Dijon mustard, salt, and pepper until smooth. Whisking well ensures the dressing is creamy and balanced.
- Dress the Salad:
- Pour the dressing over the pasta and seafood mixture. Add fresh dill and toss gently until everything is coated evenly. This lets every forkful have that perfect creamy tang and fresh herb aroma.
- Chill and Serve:
- Place the salad in the fridge for at least 30 minutes for the flavors to meld and the salad to chill thoroughly. Serve cold with lemon wedges on the side for an extra pop of citrus.

My favorite ingredient is fresh dill which really brightens the whole salad. I remember a family barbecue where everyone kept going back for more and asking what gave it that fresh twist – the dill definitely steals the show here.
Storage Tips
Keep the salad in an airtight container in the refrigerator and consume within two days for the best texture and flavor. If you plan to store it longer, consider adding the dressing just before serving to keep pasta from absorbing too much moisture.

Cultural Context
