Creamy Seafood Pasta Salad with Shrimp & Crab

Some dishes just feel like summer.

This seafood pasta salad is one of them. Tender pasta shells. Juicy little shrimp. Sweet crabmeat. All tossed in a creamy, Old Bay-kissed dressing that somehow tastes like you are sitting three feet from the ocean.

I have been making this for backyard cookouts, quiet Sunday lunches, and everything in between. And every single time, the bowl comes back empty.

The best part? It comes together in just 25 minutes.

What Makes This Salad So Good

It is all about the little details.

Shell pasta is not just cute. Those tiny “cups” actually scoop up the peas and hold the creamy dressing inside. Every bite is a full package. And the trick of squeezing lemon juice directly onto warm, freshly drained pasta? That is the move. The shells absorb the citrus right away, so the bright flavor runs through the whole dish, not just the sauce.

Old Bay seasoning does the heavy lifting here. That iconic Maryland blend of celery salt, paprika, and spices is practically made for seafood. One or two teaspoons depending on how bold you like it.

Everything You Need to Get Started

Before you touch the stove, get everything laid out. Seriously. This salad moves fast, and having your ingredients ready makes the whole process feel easy and fun.

Step-by-Step: Bringing the Coast to Your Kitchen

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add your shell pasta and cook it according to the package directions. You are going for al dente, which just means it still has a tiny bit of bite to it. Not mushy. Not chalky. Somewhere right in the middle.

Once it is done, drain it immediately.

Pro Tip: Run the pasta under cold water right after draining. This stops the cooking instantly and keeps your shells from turning soft and sad in the salad.

Step 2: Add the Lemon Juice

While the pasta is still slightly damp, transfer it to a large mixing bowl. Drizzle the lemon juice right over the warm shells and give them a gentle toss.

This step matters more than it seems. Warm pasta soaks up flavors like a sponge. So when the lemon hits it now, that brightness becomes part of the pasta itself, not just a surface coating.

Step 3: Make the Dressing

In a small bowl, whisk together the mayonnaise and Old Bay seasoning.

Start with one teaspoon of Old Bay. Taste it. If you want more of that classic coastal punch, go ahead and add the second teaspoon. There is no wrong answer here. It comes down to personal preference.

Step 4: Bring It All Together

Now for the fun part.

Add the finely chopped celery, minced onion, and thawed peas to the pasta bowl. Fold in the cooked baby shrimp and the chopped crabmeat. Pour the seasoned mayo dressing over everything and fold it all together with a large spatula.

Be gentle here. Crabmeat is delicate. If you stir too aggressively, it will fall apart and turn into a paste instead of staying in those beautiful little chunks.

Step 5: Season, Garnish, and Chill

Give the salad a taste. Add salt and pepper until it feels balanced.

Sprinkle the fresh parsley over the top. It adds a lovely pop of green and a hint of clean, herby freshness that balances the richness of the mayo dressing.

Now here is the hard part. You have to wait.

Cover the bowl and refrigerate the salad for at least two hours before serving. I know it is tempting to dig in right away. But the chill time lets all those flavors settle and meld together. The end result is a completely different, much better salad than what you tasted off the spatula.

Tips and Easy Variations

This recipe is very forgiving. Once you have the base down, it is easy to make it your own.

• Not a fan of raw onion? Swap it out for chopped green onions or chives. Milder flavor, same great texture.
• Want more vegetables? Diced bell peppers or shredded carrots add beautiful color and a satisfying crunch.
• Working with a tighter budget? Imitation crab works perfectly fine here. Just chop it into uniform pieces so every bite is consistent.
• Salad too thick after chilling? Stir in a small splash of milk or an extra squeeze of lemon juice to loosen the dressing back up.

Frequently Asked Questions

Can I make this a day ahead?

You can, and honestly, you probably should. The flavors deepen overnight as the Old Bay and seafood have more time to meld into the dressing. Just give it a good stir before serving to redistribute everything.

How long does it last in the fridge?

Because this recipe contains seafood and mayonnaise, you want to finish it within three days. Store it in a tightly sealed container to keep it fresh.

What if I don’t have shell pasta?

Fusilli (spirals) and farfalle (bowties) are both great alternatives. The key is finding a shape with nooks and crannies that can grip and hold onto the creamy dressing.

Can I make a lighter version?

Absolutely. Replace half of the mayonnaise with plain Greek yogurt. It makes the dressing tangier and noticeably lighter. The flavor profile shifts a little, but it is still really delicious.

There is something so satisfying about a dish this simple tasting this good.

It is the kind of recipe you make once and then find yourself craving every time summer rolls around. Whether you are feeding a crowd at a cookout or just looking for a no-fuss lunch that feels a little special, this seafood pasta salad always delivers.

Give it a try. And do not forget the two-hour chill. That patience is always worth it.
