This creamy, zesty Cold Italian Shrimp And Crab Seafood Pasta Salad is made with tender rotini, succulent seafood, and crisp vegetables, ready in just 25 minutes. The best flavor develops when the tangy dressing has time to meld with the chilled pasta and sweet crab meat in the refrigerator. I love serving this refreshing, crowd-pleasing dish at summer barbecues and potlucks.

Why This Classic Works

This recipe balances the natural sweetness of imitation crab and salad shrimp with the sharp, savory tang of Zesty Italian dressing. By mixing the vinaigrette with a bit of mayonnaise, you create a creamy emulsion that clings to the pasta spirals without feeling heavy or greasy like traditional mayonnaise-based salads.

When I first made this, I served it immediately and found the flavors underwhelming. I quickly learned that the secret is letting it sit; the pasta needs at least an hour to absorb the herb-infused dressing, transforming a simple mixture into a cohesive, flavorful side dish.

Cold Italian Shrimp And Crab Seafood Pasta Salad Ingredients

12 oz Tri-color rotini pasta (or shell pasta)
8 oz Imitation crab meat, flake style
8 oz Small salad shrimp, cooked and peeled
1 cup Zesty Italian dressing
1/2 cup Mayonnaise
1 cup Celery, finely diced
1/2 cup Red onion, finely chopped
1/2 cup Black olives, sliced
1/2 Red bell pepper, diced (optional)
1 tsp Old Bay seasoning
1 tbsp Fresh parsley, chopped
Salt and black pepper to taste

How To Make Cold Italian Shrimp And Crab Seafood Pasta Salad

Cook the Pasta: Boil the rotini in a large pot of salted water according to package directions until al dente. Drain immediately and rinse thoroughly under cold water to stop the cooking process and cool the noodles down.
Prepare the Seafood: While the pasta drains, chop the imitation crab meat into bite-sized chunks. Ensure the salad shrimp are fully thawed and patted dry with paper towels to remove excess water.
Mix the Dressing: In a small bowl, whisk together the Zesty Italian dressing, mayonnaise, Old Bay seasoning, and black pepper until smooth and creamy.
Combine Ingredients: In a large mixing bowl, combine the cooled pasta, crab, shrimp, celery, red onion, olives, and bell pepper. Pour the dressing mixture over the top.
Toss and Chill: Gently toss everything together until the pasta and seafood are evenly coated. Cover the bowl with plastic wrap and refrigerate for at least 1 hour before serving to allow flavors to marry.

Recipe Tips

Dry the Seafood: Water is the enemy of a creamy pasta salad. Make sure to pat your shrimp and crab dry with paper towels before adding them, or the dressing will become watery as it sits.
Don’t Skip the Rinse: Rinsing the cooked pasta under cold water removes excess starch and prevents the noodles from sticking together, ensuring a loose and appetizing salad texture.
Check Seasoning Later: Pasta absorbs salt and dressing as it chills. Taste the salad just before serving and add a splash more Italian dressing or a pinch of salt if it seems dry or bland.

What To Serve With Italian Seafood Pasta Salad

This chilled side dish pairs perfectly with grilled summer favorites like cheeseburgers, hot dogs, or BBQ chicken thighs. It also works beautifully alongside a crusty loaf of garlic bread and corn on the cob for a complete seafood-themed picnic meal.

How To Store

Store leftovers in an airtight container in the refrigerator for up to 3 days. This salad actually tastes better on the second day, but do not freeze it, as the mayonnaise and pasta texture will degrade significantly upon thawing.

FAQs

Can I use real crab meat? Yes, fresh lump crab meat is a delicious upgrade, though imitation crab is more traditional for this style of potluck salad and holds its shape well.
Why is my pasta salad dry after chilling? Pasta acts like a sponge and soaks up the dressing in the fridge. Simply stir in an extra tablespoon or two of Italian dressing just before serving to restore the creaminess.
Can I make this ahead of time? Absolutely, this dish is best made 4 to 24 hours in advance, making it an ideal choice for party prep.
