Creamy Seafood Pasta Salad with Crab, Celery & Lemon-Dill Dressing
This creamy seafood pasta salad is the perfect recipe when you want something fresh, creamy, colorful, and incredibly easy to prepare. Inspired by the dish in your photo, it combines tender pasta shells with imitation crab, crisp celery, green onion, creamy mayonnaise dressing, and a bright touch of lemon and fresh dill.
The little pasta shells are especially good for this recipe because their shape catches the creamy dressing and small pieces of seafood and vegetables in every bite. The result is a satisfying cold salad that works beautifully as a light lunch, a picnic side dish, a potluck recipe, or a make-ahead summer meal.
The combination of creamy dressing, sweet crab-style seafood, crunchy celery, and fresh lemon gives this salad a wonderful balance. It isn’t overly heavy despite the creamy texture, and the lemon and dill help keep the flavors bright.

Ingredients
For the Pasta Salad
- 12 ounces (340 g) small shell pasta or medium shell pasta
- 12 ounces (340 g) imitation crab meat
- 2 celery stalks, finely diced
- 3–4 green onions, thinly sliced
- 2 hard-boiled eggs, chopped
- 2 tablespoons fresh dill, finely chopped
- 1 small cucumber, finely diced, optional
- ½ cup finely shredded carrot, optional
- ¼ teaspoon salt
- ¼ teaspoon freshly ground black pepper
For the Creamy Dressing
- 1 cup mayonnaise
- ¼ cup sour cream or plain Greek yogurt
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon Dijon mustard
- 1 teaspoon sugar or honey
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- 1–2 tablespoons finely chopped fresh dill
- Salt, to taste
- Black pepper, to taste
For Garnishing
- Fresh dill
- Lemon wedges
- A few thin slices of green onion
- Optional paprika
- Optional additional shredded imitation crab
Step 1: Cook the Pasta
Begin by bringing a large pot of generously salted water to a boil.
Add the shell pasta and cook according to the package directions until it is al dente. You want the pasta to be tender but still have a little bite because it will continue absorbing some moisture from the dressing while the salad chills.
Avoid overcooking the pasta. Very soft pasta can become mushy once combined with mayonnaise and refrigerated.
Once the pasta is finished, drain it thoroughly.
For a cold pasta salad, rinse the pasta briefly under cold running water. This stops the cooking process and cools the pasta quickly. It also removes some excess starch, which helps prevent the shells from sticking together.
Allow the pasta to drain completely.
You don’t want excess water sitting in the bottom of your salad because it can dilute the dressing.
Transfer the cooled pasta to a large mixing bowl.
Step 2: Prepare the Imitation Crab
For this recipe, imitation crab meat works extremely well. It has a slightly sweet seafood flavor and a soft texture that blends beautifully with the creamy dressing.
You can either cut the imitation crab into small pieces or gently pull it apart into strips with your fingers.
For a salad like the one pictured, I recommend using a combination of small chunks and shredded pieces. This gives the finished salad a more interesting texture and distributes the seafood throughout the pasta.
Place the prepared crab in a bowl.
If your imitation crab contains excess moisture, gently pat it dry with paper towels before adding it to the salad.
You can also use real cooked crab meat if you prefer. However, imitation crab makes this recipe much more economical and convenient for a large gathering.
Step 3: Chop the Vegetables
Next, prepare the vegetables.
Finely dice the celery. Celery is important because it adds a wonderful crunchy texture to an otherwise creamy salad.
Thinly slice the green onions.
If you’re using cucumber, cut it into very small cubes. If the cucumber contains a lot of watery seeds, you can remove the seeds before chopping. This helps keep the salad from becoming watery.
For extra color and a slight natural sweetness, you can add finely shredded carrot.
Chop the hard-boiled eggs into small pieces.
Finally, finely chop the fresh dill.
Fresh dill is particularly delicious in seafood salads because its fresh, slightly grassy flavor complements both crab and lemon.
Step 4: Make the Creamy Lemon-Dill Dressing
Now prepare the dressing.
In a medium bowl, combine:
- mayonnaise
- sour cream or Greek yogurt
- lemon juice
- lemon zest
- Dijon mustard
- sugar or honey
- garlic powder
- onion powder
- fresh dill
- salt
- black pepper
Whisk everything together until completely smooth.
Taste the dressing before adding it to the salad.
This is an important step because the flavor can easily be adjusted at this point.
If you want it brighter, add another teaspoon of lemon juice.
If you want it creamier and richer, add another spoonful of mayonnaise.
If you prefer a slightly sweeter seafood salad, add a small amount of sugar.
If you love dill, add another tablespoon.
The dressing should taste slightly stronger than you might expect because the pasta and vegetables will soften its flavor once everything is mixed together.
Step 5: Combine Everything
Add the imitation crab, celery, green onions, chopped eggs, cucumber if using, carrot if using, and fresh dill to the cooled pasta.
Gently toss everything together.
Don’t mix too aggressively because the imitation crab and eggs can break apart easily.
Pour about three-quarters of the dressing over the pasta mixture.
Using a large spoon or rubber spatula, gently fold the dressing through the salad.
Make sure the dressing reaches the bottom of the bowl and coats the pasta shells evenly.
Add more dressing as needed.
You may not need every drop depending on how creamy you prefer your pasta salad.
Remember that the pasta will absorb some of the dressing while it chills, so don’t make the salad too dry at this stage.
Step 6: Season and Taste
Taste the finished salad.
Add additional salt and pepper if needed.
You can also add another squeeze of lemon juice if you want a fresher flavor.
For a little extra seafood flavor, you can add a tiny amount of Old Bay-style seafood seasoning or paprika.
Be careful with salty seasonings, though, because imitation crab can already contain a fair amount of sodium.
At this point, the salad should taste creamy, slightly tangy, mildly sweet, fresh, and savory.
Step 7: Chill the Salad
Cover the bowl tightly with plastic wrap or transfer the salad to an airtight container.
Refrigerate for at least 1 hour.
For the best flavor, I recommend chilling it for approximately 2 hours.
This gives the ingredients time to blend together.
The pasta will absorb some of the dressing, while the celery, dill, lemon, and seafood flavors will become more pronounced.
If you’re making the salad the day before serving, reserve a few tablespoons of dressing in a separate container.
The following day, stir the salad and add the reserved dressing if it has become too thick.
Why This Seafood Pasta Salad Works So Well
One of the best things about this recipe is the contrast between textures.
The pasta is soft and tender.
The imitation crab provides a delicate, slightly chewy seafood texture.
The celery gives the salad a crisp crunch.
The green onions add freshness and mild onion flavor.
The eggs contribute richness.
And the creamy lemon-dill dressing ties everything together.
The lemon is particularly important. Mayonnaise-based salads can sometimes taste heavy, but lemon juice adds acidity that cuts through the richness and makes every bite taste fresher.
Fresh dill adds another layer of flavor that pairs naturally with seafood.
Tips for Making the Best Seafood Pasta Salad
1. Don’t overcook the pasta
This is probably the most important tip.
Cook the pasta only until al dente. Overcooked shells can become soft and fall apart after they absorb the dressing.
2. Cool the pasta completely
Never mix hot pasta directly with mayonnaise.
Hot pasta can make the dressing greasy and cause the vegetables to lose their crisp texture.
Let the pasta cool first.
3. Don’t add too much dressing immediately
Start with about three-quarters of the dressing.
You can always add more, but it’s difficult to rescue a salad that has become excessively wet.
4. Use fresh lemon
Fresh lemon juice makes a noticeable difference.
Bottled lemon juice can work in a pinch, but fresh lemon gives the dressing a cleaner, brighter flavor.
5. Give it time to chill
This isn’t a salad that needs to be served immediately.
A little refrigeration makes it significantly better.
The flavors become more integrated and the dressing coats the pasta beautifully.
6. Add fresh dill at the end
If possible, reserve a little fresh dill for garnish.
It adds a beautiful fresh aroma and makes the salad look much more appetizing.
Optional Variations
Add Shrimp
For a more substantial seafood salad, add approximately 1 cup of small cooked shrimp.
Chop larger shrimp into bite-sized pieces before mixing them into the salad.
The combination of shrimp and crab is delicious.
Use Real Crab
If you have access to good-quality cooked crab meat, you can substitute it for imitation crab.
Real crab will give the salad a more delicate and authentic seafood flavor.
Add More Vegetables
You can customize the salad with vegetables such as:
- Bell peppers
- Sweet corn
- Peas
- Cucumber
- Shredded carrot
- Red onion
- Radishes
Keep the pieces relatively small so that they blend naturally with the pasta.
Make It Spicy
If you enjoy a little heat, add:
- A pinch of cayenne pepper
- A few drops of hot sauce
- Finely chopped jalapeño
- Crushed red pepper flakes
A small amount is enough to give the salad a pleasant kick without overpowering the seafood.
What to Serve With It
This seafood pasta salad is extremely versatile.
Serve it as a side dish alongside grilled chicken, grilled fish, burgers, sandwiches, or barbecue dishes.
It also works beautifully as a light lunch.
For a summer gathering, place the salad in a large serving bowl and garnish it with fresh dill and lemon wedges. The bright colors make it especially attractive on a buffet table.
You can also serve it with toasted bread, crackers, or a simple green salad for a complete meal.
How to Store It
Store leftover seafood pasta salad in a tightly covered container in the refrigerator.
Because this recipe contains mayonnaise, seafood, and eggs, keep it properly refrigerated and don’t leave it sitting at room temperature for extended periods.
For the best quality, enjoy it within 2–3 days.
Before serving leftovers, stir the salad well.
If the pasta has absorbed a lot of dressing and the salad seems dry, mix in a spoonful of mayonnaise or sour cream together with a small squeeze of lemon juice.
Make-Ahead Instructions
This is actually an excellent make-ahead recipe.
You can prepare the pasta and vegetables several hours before serving.
For the best texture, combine everything with most of the dressing and refrigerate it.
If preparing it the day before, reserve a little dressing separately.
The next day, stir everything together and add the reserved dressing as necessary.
Garnish with fresh dill and lemon slices immediately before serving.
This makes it a convenient recipe for parties, family dinners, picnics, holidays, and potlucks.
