This is a cold pasta salad built around Cajun-seasoned shrimp, charred corn, crunchy vegetables, and a creamy, tangy dressing. It comes together in about 40 minutes and holds up well in the fridge, which makes it a genuinely useful dish for lunches, potlucks, or a no-fuss dinner. The spice level is real but not punishing, and every component pulls its weight.
Why this recipe works
Two things make this salad succeed where similar recipes fall flat. First, the shrimp are coated with both Cajun seasoning and a small amount of brown sugar before hitting a hot skillet. The sugar accelerates browning and gives the shrimp a slightly caramelized edge that plain seasoning alone wonโt produce โ this is what keeps the shrimp interesting once everything is cold and mixed together. Second, the dressing uses a split base of mayonnaise and Greek yogurt rather than mayo alone. Mayonnaise clings to pasta well but can taste heavy; the yogurt cuts through that richness and adds a mild tang that keeps the whole bowl from feeling dense. Apple cider vinegar, lemon juice, and honey are all in there too, so the dressing is genuinely balanced โ salty, acidic, slightly sweet โ and it coats cavatappiโs ridges and spirals far better than a thinner vinaigrette would.
If something goes sideways
- Shrimp turned rubbery: They overcooked. Large shrimp need only 1โ2 minutes per side over high heat. Pull them the moment they curl into a loose C-shape and turn opaque. A tight O-shape means theyโve gone too far โ nothing fixes that, so watch the pan closely.
- Pasta tastes bland even after dressing: The pasta itself wasnโt salted enough during cooking. Rinsing it (which this recipe does to stop cooking) also washes away surface starch that helps dressing cling. Toss the cooled pasta with a small pinch of salt before adding the dressing, and taste again before serving.
- Dressing looks broken or greasy: This usually happens if the dressing hits warm pasta or shrimp. Let everything cool to at least room temperature before combining. If it still looks separated, whisk a teaspoon of cold water into the dressing bowl before pouring.
- Corn didnโt char โ it just steamed: The skillet wasnโt hot enough, or the corn was crowded. Use a dry skillet (no oil for the corn), get it very hot, and spread the kernels in a single layer. Donโt stir for at least 90 seconds. If your skillet is small, char the corn in two batches.
- Salad tastes flat after chilling: Cold mutes salt and acid. Before serving, taste and add a small squeeze of lemon juice and a pinch of salt. This is normal and expected โ always re-season a chilled pasta salad right before it goes on the table.
Leftovers and meal prep
Store leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will absorb dressing as it sits, so the salad gets denser by day two โ stir in a tablespoon of mayonnaise or a small splash of lemon juice to loosen it before serving. If youโre making this ahead for a party, dress it at the table โ a pre-dressed salad goes limp fast, and the cherry tomatoes will weep into the dressing overnight. To prep in advance, cook the pasta, char the corn, and make the dressing up to 24 hours ahead, storing each separately in the fridge. Cook the shrimp the day of serving; theyโre quick and taste noticeably better fresh. The celery and scallions can be sliced ahead and kept in a small covered bowl โ they stay crisp for two days without any extra effort.

Instructions
- Cook the pasta: Bring a large pot of water to a rolling boil (212ยฐF / 100ยฐC). Stir in 2 tbsp kosher salt, add the pasta, and cook until al dente, 8-20 minutes per package directions. Drain, rinse briefly under cool water to stop the cooking, and toss with 1 tsp olive oil to prevent sticking. Spread on a tray to cool while you proceed.
- Whisk the Cajun dressing: In a large mixing bowl, whisk together mayonnaise, Greek yogurt, Dijon, lemon juice, apple cider vinegar, honey, 1 tbsp Cajun seasoning, smoked paprika, grated garlic, black pepper, and 1/2 tsp kosher salt until smooth and emulsified, 1-3 minutes. Set aside.
- Char the corn and bell pepper: Heat a large skillet over medium-high until the oil shimmers. Add 1 tbsp neutral oil, then the corn and diced red bell pepper. Sautรฉ, stirring occasionally, until lightly charred and tender-crisp, 6-8 minutes. Season with a pinch of salt, transfer to a plate, and let cool 5 minutes. (This can be done while the pasta cooks.)
- Sear the shrimp: Pat shrimp dry with paper towels. Toss with 1 tbsp Cajun seasoning (from the shrimp section), brown sugar, and 1 tbsp olive oil. Return the skillet to medium-high heat; when just smoking, add shrimp in a single layer and cook until opaque with lightly blackened edges, about 2 minutes per side (internal temp 145ยฐF / 63ยฐC). Transfer to a plate to cool slightly.
- Assemble the salad: To the bowl with dressing, add the cooled pasta, charred corn and peppers, celery, red onion, cherry tomatoes, scallions, parsley, and lemon zest. Fold gently with a spatula until evenly coated. Add the warm shrimp and toss just to combine; season to taste. If desired, stir in hot sauce for extra heat.
- Chill and serve: Cover and chill until the salad is lightly cold and flavors meld, about 10 minutes (target 40ยฐF / 4ยฐC). Garnish with additional parsley and black pepper just before serving.
Notes
Chef's Tips
- Season your water: Salting pasta water generously ensures the pasta itself carries flavor into the salad.
- Dry shrimp = better sear: Moisture inhibits browning. Pat shrimp thoroughly before seasoning to achieve that Cajun crust.
- Balance the heat: Cajun blends vary; start modestly and build with hot sauce at the end so the spice doesn't overwhelm the sweet corn.
- Keep the crunch: Sautรฉ corn and peppers just until blistered, so they retain snap, which lifts the creamy dressing.
- Make-ahead: Toss pasta and vegetables with half the dressing, then chill. Add shrimp and the remaining dressing just before serving to keep textures vivid.
- Swap suggestions: Use andouille in place of shrimp (pan-crisp 4-5 minutes) or smoked turkey for a land option. Gluten-free pasta works well; rinse briefly to remove excess starch.
- Storage: Refrigerate airtight up to 2 days. Refresh with a squeeze of lemon and a spoon of yogurt if it tightens up.

Common questions
Can I use frozen shrimp instead of fresh?
Yes โ frozen shrimp work fine here. Thaw them completely in cold water, then pat them very dry with paper towels before seasoning; surface moisture is the main reason shrimp steam instead of sear, so drying them thoroughly is the one step you shouldnโt skip.
How spicy is this, and can I dial it back?
Itโs noticeable but not hot โ most commercial Cajun blends are more smoky and savory than fiery. To reduce the heat, cut the Cajun seasoning on the shrimp to 1 teaspoon and increase the smoked paprika in the dressing by the same amount to keep the flavor depth without adding more cayenne.
Can I use canned or frozen corn instead of fresh?
Frozen corn works well; thaw and dry it before charring, and it will brown almost as well as fresh. Canned corn is softer and holds more moisture, so it wonโt char cleanly โ drain and dry it as much as possible, and accept that youโll get color on some kernels but not the same texture as fresh or frozen.
