Ingredients

Pasta Salad

1 lb rotini pasta
1.5 lbs large shrimp , peeled, deveined, cooked and chilled
1 cup cherry tomatoes , halved
1 cup cucumber , diced
0.5 cup red onion , finely diced
0.5 cup black olives , sliced
1 cup celery , thinly sliced
0.25 cup fresh parsley , chopped

Creamy Dressing

1 cup mayonnaise
3 tbsp lemon juice , freshly squeezed
1 tbsp Dijon mustard
1 tsp garlic powder
1 tsp Old Bay seasoning
0.5 tsp smoked paprika
0.5 tsp salt , plus more to taste
0.25 tsp black pepper
1 tsp honey

Instructions

Cook the Pasta

Bring a large pot of well-salted water to a boil and cook the rotini according to package directions until al dente. Do not overcook, since soft pasta turns mushy once it sits in the dressing.

Drain the pasta and rinse it immediately under cold water until completely cool. Shake off the excess water and spread it on a sheet pan for a few minutes to dry out slightly.

Cook the Shrimp

If using raw shrimp, bring a pot of salted water to a boil with a halved lemon squeezed in. Add the shrimp and cook for 2 to 3 minutes, just until they turn pink and curl slightly.

Transfer shrimp immediately to a bowl of ice water to stop the cooking. Once chilled, drain, pat dry, and cut each shrimp into two or three pieces depending on their size. This makes the salad easier to scoop and serve.

Make the Dressing

Whisk together the mayonnaise, lemon juice, Dijon mustard, garlic powder, Old Bay, smoked paprika, honey, salt, and pepper in a medium bowl until smooth and fully combined.

Taste the dressing and adjust the salt and lemon to your liking. It should be tangy, a little savory, and just barely sweet.

Assemble and Chill

Add the cooled pasta, shrimp, cherry tomatoes, cucumber, red onion, olives, celery, and parsley to a large mixing bowl.

Pour the dressing over everything and toss gently until all the ingredients are evenly coated. Don't be shy with the dressing since the pasta will absorb some of it as it chills.

Cover the bowl and refrigerate for at least 1 hour before serving. Give it a good stir right before putting it out, and add a sprinkle of extra parsley and a light dusting of Old Bay on top for a nice presentation.

Tips & Notes

Cook the pasta slightly firmer than you think you need, since it softens more once tossed with the dressing and chilled.
Pre-cooked frozen shrimp works great here. Just thaw it overnight in the fridge and pat it very dry before adding it to the salad.
Make this the night before the party. The flavors meld together beautifully overnight and it saves you a ton of stress on the day.
If the salad looks a little dry after chilling, stir in a spoonful or two of mayo and a small squeeze of lemon to bring it back to life.
For a crowd of 20 or more, simply double the recipe. This scales up easily and the dressing ingredients stay proportional.

Storage: Store covered in the refrigerator for up to 3 days. Stir before serving and add a little extra mayo and lemon juice if needed to freshen the dressing.

Why This Salad Works So Well for a Potluck

The thing about potluck food is that it has to travel well, sit out for a while, and still taste good after strangers have scooped it a dozen times. This shrimp pasta salad checks every one of those boxes. The rotini holds onto the creamy dressing instead of letting it pool at the bottom, and the crunchy vegetables stay crisp even after a few hours.

The Old Bay seasoning is the secret weapon here. It gives the whole dish that unmistakable coastal, summery flavor that just makes people stop mid-bite and ask what's in it. Paired with fresh lemon juice and a tiny bit of honey, the dressing is tangy and bright without tasting heavy or overly rich.

Making it ahead is genuinely the move. Bringing a dish that is already done and just needs to be uncovered is a gift to yourself on a busy party day.

Easy Ways to Customize This Recipe

This salad is forgiving and flexible, which is part of why I love it. Swap the rotini for bowtie pasta or shells if that's what you have on hand, and it works just as well. Diced bell peppers, corn cut fresh off the cob, or sliced avocado added right before serving all make excellent additions.

If you want to lighten up the dressing, replace half the mayo with plain Greek yogurt. It keeps the creaminess but adds a little tang and cuts down on the richness. For anyone who loves a little heat, a pinch of cayenne or a few dashes of hot sauce stirred into the dressing goes a long way.
