Creamy Shrimp Pasta Salad is cool, creamy, and packed with tender shrimp, crisp celery, and bright fresh herbs.

It is perfect for summer lunches, potlucks, cookouts, or an easy make-ahead dinner on warm nights.

Prep mode (keeps screen awake)

Cook and cool the pasta

Boil the rotini in well-salted water until al dente, according to the package directions.
Drain it, rinse under cold water, and let it cool completely so the dressing stays creamy.
Mix the creamy dressing

Whisk the mayonnaise, sour cream, Dijon mustard, lemon juice, vinegar, garlic powder, paprika, salt, and pepper until smooth.
Taste and adjust the salt, pepper, or lemon if you want a brighter finish.
Combine the salad

If the shrimp are large, chop them into bite-size pieces first.
In a large bowl, combine the cooled pasta, shrimp, red onion, celery, parsley, and dill.
Fold in the dressing gently until every piece is evenly coated.
Chill and serve

Cover and chill the salad for at least 30 minutes before serving.
Stir once before serving, then garnish with extra dill or parsley if you like.

Rotini -> cavatappi: Cavatappi grabs the creamy dressing in every curl and keeps a nice chewy bite. The shape also gives the salad a playful look.
Sour cream -> plain Greek yogurt: Greek yogurt keeps the dressing tangy and creamy while making it a bit lighter. The texture stays thick and spoonable.
Cooked shrimp -> chopped cooked lobster: Lobster makes the salad sweeter and more luxurious with a tender bite. It turns the dish into a party-ready option without changing the creamy style.

Salt the pasta water: Well-salted water seasons the rotini from the inside. That keeps the finished salad from tasting flat, even when served cold.
Cool the pasta completely: Warm pasta melts the dressing and turns it greasy. Cool noodles also hold their shape better during mixing.
Pat the shrimp dry: Dry shrimp keeps extra water out of the bowl. That helps the dressing stay thick and cling to the pasta.
Chill, then stir again: A short chill helps the flavors blend and firms the dressing. Stir once before serving to redistribute any dressing at the bottom.
Cut vegetables evenly: Small, even pieces give every bite a balanced texture. They also keep the salad easy to scoop and eat.

Why did my pasta salad turn dry after chilling?: Pasta absorbs dressing as it rests in the fridge. Stir in a spoonful of mayonnaise, sour cream, or lemon juice before serving.
Should I rinse the pasta?: Yes, for this cold salad, a quick rinse stops the cooking and cools the noodles fast. Do not over-rinse, or the pasta may lose too much starch.
How far ahead can I make it?: You can make it up to one day ahead. Keep it covered, then stir and taste for seasoning before serving.
How do I keep the shrimp tender?: Use cooked shrimp only long enough to chill in the salad. If cooking raw shrimp, stop as soon as they turn pink and curl lightly.
Can I add more vegetables?: Yes, diced cucumber, sweet bell pepper, or peas work well here. Add them dry, so the dressing does not thin out.
