Seafood Pasta Salad Recipe With Crabmeat and Shrimp and Mayo: Coastal Flavors in a Creamy Bowl

There’s something special about bringing coastal flavors to your table with this chilled pasta dish. I’ve refined this recipe to highlight the natural sweetness of crabmeat and shrimp while creating a creamy texture that holds up beautifully.

The secret lies in cooking the pasta al dente and folding it with the seafood while still warm, allowing the flavors to meld. A light hand with the mayo ensures the dressing coats without overwhelming, letting the seafood shine through.

You’ll end up with a salad that’s rich yet balanced, with tender pasta, plump shrimp, and delicate crabmeat in every bite. The flavors taste even better after a few hours in the fridge, making it perfect for meal prep.

Ideal for summer gatherings or light lunches, this dish brings the essence of the seaside to your kitchen.

Ingredients for Seafood Pasta Salad Recipe with Crabmeat and Shrimp and Mayo

Bright, fresh ingredients bring coastal flavors to your table in this creamy dish.

The seafood is the star here. Fresh lump crabmeat and wild-caught shrimp give the best texture and flavor—look for them at Whole Foods or a trusted seafood counter. If using frozen, thaw overnight in the fridge and drain well. For pasta, I love De Cecco or Barilla for their al dente hold, but any short shape works (just avoid long strands).

No crabmeat? Imitation crab works in a pinch (though texture differs). Swap shrimp for scallops or chopped lobster if you’re feeling fancy. The mayo can be light, but full-fat gives that rich, creamy coating the intro promises. No fresh herbs? Dried dill and parsley at one-third the amount gets you close. The Dijon mustard can be yellow, but Dijon adds more depth.

This keeps beautifully for 3-4 days in the fridge—actually tastes better after a few hours. Store in an airtight container, and give it a good stir before serving. Not freezer-friendly (the mayo separates), so make just what you’ll eat within the week.

Step-by-Step Instructions for Seafood Pasta Salad

This method ensures your salad stays creamy and fresh with every bite.

Step 1: Cook and Cool the Pasta

Bring a large pot of salted water to a rolling boil and cook the 12 oz pasta according to package directions until al dente. I always taste-test a minute before the suggested time—you want it just tender with a slight bite.

Drain immediately and rinse under cold water to stop the cooking process. This also washes away excess starch that could make the salad gummy. Spread the pasta on a baking sheet and refrigerate for 15 minutes to cool completely—warm pasta will melt the mayonnaise and make the dressing thin.

Step 2: Prepare the Vegetables and Herbs

While the pasta cools, finely dice the 1 cup celery and 0.5 cup red bell pepper. Consistency matters here—small, even pieces distribute better in every forkful. For the 0.25 cup red onion, I soak the chopped pieces in cold water for 5 minutes to mellow their sharpness, then drain well.

Chop the 2 tbsp fresh dill and 2 tbsp fresh parsley just before adding. Fresh herbs wilt quickly once cut, so I keep them whole until the last moment. This preserves their bright color and flavor in the finished dish.

Step 3: Make the Creamy Dressing

In a large bowl, whisk together the 0.75 cup mayonnaise, 2 tbsp lemon juice, 1 tbsp Dijon mustard, 1 tsp Old Bay seasoning, 0.5 tsp salt, and 0.5 tsp black pepper until smooth. The lemon juice and mustard balance the richness of the mayonnaise while adding a tangy brightness.

Taste the dressing and adjust seasoning if needed. I often add a pinch more salt if the Old Bay isn’t prominent enough. The dressing should be creamy but pourable—if it’s too thick, the pasta won’t coat evenly.

Step 4: Combine All Ingredients

Add the cooled pasta, 1 lb cooked shrimp, 8 oz lump crabmeat, celery, red bell pepper, and red onion to the dressing. Gently fold everything together with a spatula to avoid breaking up the seafood. The crabmeat is delicate, so I use a lifting motion rather than stirring vigorously.

Sprinkle the chopped dill and parsley over the top and fold in just until combined. At this point, the salad should look glossy and well-coated. If it seems dry, add another spoonful of mayonnaise, but remember it will release more moisture as it chills.

Step 5: Chill and Serve

Cover the bowl with plastic wrap and refrigerate for at least 1 hour before serving. This resting time allows the flavors to meld and the pasta to absorb some of the dressing. I’ve found that 2 hours is ideal for the best texture and taste.

Give it a quick stir before serving to redistribute the dressing. The seafood should glisten, the vegetables should be crisp, and every bite should have a perfect balance of creamy, tangy, and fresh flavors.

Best Sauces and Condiments for These Flavors

Creamy Additions

For extra richness, I fold in 2 tbsp sour cream or Greek yogurt to the mayo base. This adds a subtle tang that complements the seafood beautifully. The texture becomes even creamier, perfect for coating every piece of pasta. 💛

Zesty Enhancements

Add 1 tsp prepared horseradish to the dressing for a subtle kick. It pairs wonderfully with the crab and shrimp, adding a new dimension without overpowering. I also love a dash of Worcestershire sauce for umami depth.

Fresh Herb Infusions

For a brighter twist, stir in 1 tbsp chopped fresh tarragon or chives along with the dill and parsley. Tarragon adds a slight anise note that elevates the seafood flavors, while chives bring a mild onion bite.

Citrus Variations

Swap the lemon juice for 2 tbsp lime juice or a mix of both for a tropical touch. I’ve also used 1 tsp lemon zest for an extra pop of citrus aroma. The acidity balances the creaminess perfectly.

Spicy Options

For heat lovers, add ½ tsp cayenne pepper or 1 tsp sriracha to the dressing. A pinch of Cajun seasoning also works well, enhancing the Old Bay’s warmth. Adjust to taste for your preferred spice level.

Umami Boosters

Stir in 1 tsp fish sauce for a salty, savory depth that enhances the seafood. It’s a secret ingredient I learned from my favorite coastal diner. The flavor blends seamlessly with the mayo base. 🌟
