This crab pasta salad brings together the comfort of a creamy macaroni-style salad and the fresh, lightly sweet flavor of seafood. Rotini is especially useful because its spirals catch the lemon-dill dressing, peas, and tiny pieces of vegetable in every bite.
It is also a practical make-ahead recipe. The salad needs time to chill, allowing the flavors to mingle, so you can prepare it in the morning for lunch or assemble it before guests arrive.

Ingredients You’ll Need
The ingredient list is simple, but each component contributes something important. The pasta provides substance, imitation crab adds a sweet seafood flavor, and the vegetables keep the salad crisp and colorful.
- Pasta: Use 12 ounces of rotini or another short pasta such as elbow macaroni, shells, bow ties, or tri-color rotini.
- Crabmeat: Thaw 12 ounces of imitation crabmeat and cut it into bite-size pieces. Real cooked crabmeat can be used instead; remove any shell fragments and keep it refrigerated.
- Dressing: One cup of mayonnaise and one-half cup of sour cream create a creamy base, while lemon juice, dill, garlic powder, salt, and pepper add balance.
- Vegetables: Thawed peas, celery, red bell pepper, and green onions provide sweetness, crunch, color, and a mild onion flavor.
For the best texture, thaw the peas completely and drain them well. Chop the celery and bell pepper finely enough to distribute throughout the salad without overpowering the pasta or crab.
How to Make It Step-by-Step
Step 1: Start by bringing a large pot of generously salted water to a boil. Add the pasta and cook it according to the package directions until just tender, usually 8–10 minutes; avoid cooking it past tender because it will soften slightly as it chills in the dressing.
Step 2: Drain the pasta immediately and rinse it under cold water until it is cool to the touch. Drain it thoroughly, since water clinging to the noodles can make the creamy dressing watery and reduce its flavor.
Step 3: While the pasta cools, whisk the mayonnaise, sour cream, fresh lemon juice, dried dill weed, garlic powder, one-half teaspoon salt, and black pepper in a large bowl. Continue whisking until the dressing is smooth, with the seasonings evenly distributed.
Step 4: Add the cooled pasta, thawed imitation crabmeat, peas, chopped celery, red bell pepper, and green onions to the bowl. Use a spatula or large spoon to fold everything together gently, taking care not to crush the crab into tiny shreds.
Step 5: Cover the bowl tightly and refrigerate the salad for at least 1 hour. Chilling gives the dressing time to coat the pasta and lets the dill, lemon, garlic, and seafood flavors come together.
Step 6: Stir the salad before serving and taste it once more. If it needs more seasoning, add a small amount of salt, pepper, or lemon juice according to your preference.
Chef Tips for the Best Texture
Do not overcook the pasta. Slightly firm noodles are ideal because they remain pleasantly chewy after absorbing some of the dressing during the 1–2 hour chilling period.
Reserve a few tablespoons of the dressing before combining everything, then store it separately in the refrigerator. Mayonnaise-based pasta salads often thicken as they chill, and the reserved dressing makes it easy to refresh the consistency before serving.
Fold rather than stir aggressively once the crab is added. This keeps the pieces recognizable and gives the finished salad a more appealing texture.

Easy Variations to Try
This recipe is flexible while keeping its creamy seafood character. Swap the rotini for elbow macaroni, shells, bow ties, or tri-color rotini when you want to use what is already in your pantry.
- Add 1–2 tablespoons of sweet pickle relish or finely chopped dill pickles for a tangy, slightly sweet flavor.
- Replace part of the mayonnaise with ranch dressing for a different herb profile.
- Add 1–2 tablespoons of milk if the chilled salad becomes too thick.
- Fold in chopped hard-boiled egg, cucumber, shredded carrot, or a small amount of Old Bay seasoning.
- Use real cooked crabmeat for a richer salad, checking carefully for shell fragments before adding it.
When adding extra ingredients, keep the additions modest so the pasta and crab remain the main features. Taste after each change, particularly when using pickle relish, Old Bay seasoning, or ranch dressing because each can add salt.
Serving, Storage, and Food Safety
Serve this salad cold in a chilled bowl, garnished with a few green onion slices or a small sprinkle of dried dill. It pairs well with grilled foods, sandwiches, simple roasted vegetables, or a platter of fresh fruit.
Keep the salad refrigerated at 40°F/4°C or colder. Do not leave it at room temperature for more than 2 hours, or more than 1 hour in hot conditions, because it contains mayonnaise, sour cream, and seafood.
For a complete casual menu, serve the salad alongside a warm bowl of comforting tortellini soup. Finish with a tropical treat such as these coconut-pineapple dessert bars, or keep breakfast-style baking on hand with these bakery-style blueberry muffins.

Method
- Bring a large pot of salted water to a boil. Cook the rotini according to the package directions until just tender, usually 8–10 minutes, then drain and rinse under cold water until cool.

- In a large mixing bowl, whisk together the mayonnaise, sour cream, lemon juice, dried dill, garlic powder, salt, and black pepper until smooth and evenly combined.
- Add the cooled pasta, imitation crabmeat, thawed peas, celery, red bell pepper, and green onions to the dressing. Fold gently with a large spatula so the ingredients are coated without breaking up the crab too much.
- Cover the bowl and refrigerate the salad for at least 1 hour before serving. Stir well just before serving, then taste and adjust the seasoning if needed.
