This is a creamy shell pasta salad built around oven-roasted sweet corn, with a lime-and-chili dressing that leans on elote flavors โ cotija, smoked paprika, jalapeรฑo. It feeds six as a side and holds up well at room temperature, which makes it genuinely useful at cookouts and potlucks. The total active time is under 25 minutes.
What makes this version work
Two things separate this from a standard mayo pasta salad. First, the corn goes into a 450ยฐF oven rather than straight from the can or cob. Twelve to fifteen minutes of dry heat drives off moisture and chars the edges, which gives the kernels a slightly smoky flavor that a creamy dressing would otherwise bury. Second, the dressing uses both mayonnaise and sour cream โ mayo for body and cling, sour cream for tang. That combination is thick enough to coat every shell without pooling at the bottom of the bowl, so the last scoop tastes as good as the first.
About the ingredients
- Cotija cheese: Sold near other Mexican cheeses at most grocery stores. Itโs dry, crumbly, and salty โ closer to a dry feta than to Parmesan. If you canโt find it, a well-drained dry feta works, but reduce any added salt in the dressing slightly since feta runs saltier.
- Smoked paprika: Regular paprika wonโt give the same result. The smoked version reinforces the char on the corn. Itโs widely available and worth keeping on hand.
- Sour cream swap: Plain full-fat Greek yogurt works as a 1:1 replacement and adds a bit more tang. Low-fat versions make the dressing thinner and slightly watery.
- Fresh vs. frozen corn: Fresh corn cut from the cob roasts better because it has less surface moisture. Frozen corn works, but pat it dry with paper towels before tossing with oil or it will steam instead of char.
What can go wrong
- Pasta absorbs all the dressing and the salad turns dry: Shell pasta keeps drinking up dressing as it sits. Reserve two or three tablespoons of dressing separately and stir it in just before serving if the salad looks tight.
- The corn steams instead of roasting: This happens when kernels are crowded or still wet. Spread them in a genuine single layer with space between โ use two pans if needed. A crowded pan traps steam and you lose the char entirely.
- The dressing tastes flat: Lime juice varies a lot in acidity. Taste the dressing before adding the pasta and adjust with a small extra squeeze of lime or a few drops more apple cider vinegar. Season after mixing everything together, not just the dressing alone.
- Jalapeรฑo heat is uneven: Capsaicin concentrates near the seeds and membrane. After seeding, rinse the minced jalapeรฑo briefly under cold water and pat dry โ this softens the heat without losing the flavor.
- Cotija disappears into the salad: If you stir it in too early, it breaks down and turns the dressing gritty. Add it last, right before serving, so it stays in distinct crumbles.
Keeping leftovers crisp
Store leftovers in an airtight container in the refrigerator for up to three days. The pasta will continue to absorb dressing overnight, so the salad will be noticeably denser on day two โ loosen it with a tablespoon of sour cream or a small squeeze of lime before eating. The scallions and cilantro soften after about 24 hours; if youโre making this a day ahead, hold those two ingredients out and stir them in fresh before serving. Dress it at the table if youโre bringing it to a party โ a pre-dressed salad that sits in a warm car for an hour goes limp and loses the textural contrast that makes it worth eating. The roasted corn and diced bell pepper hold up fine either way.

- 3 cups sweet corn kernels fresh cut from 4 ears, or thawed if frozen
- 1 tbsp extra-virgin olive oil for roasting corn
- ยผ tsp kosher salt for roasting corn
- ยผ tsp freshly ground black pepper for roasting corn
- 1 tbsp kosher salt for pasta water
- 12 oz small shell pasta or ditalini or elbows
- 1 cup red bell pepper small dice
- 4 whole scallions thinly sliced
- 1 pepper jalapeรฑo seeded and finely minced
- โ cup fresh cilantro chopped
- ยฝ cup cotija cheese crumbled
For the dressing
- ยฝ cup mayonnaise full-fat for best texture
- โ cup sour cream or plain Greek yogurt
- 2 tbsp fresh lime juice about 1 large lime
- 1 tbsp apple cider vinegar
- 1 tsp Dijon mustard
- 1 tsp honey
- 1 clove garlic finely grated
- 1 tsp chili powder
- ยฝ tsp smoked paprika
- 1 tsp kosher salt for dressing
- ยฝ tsp freshly ground black pepper for dressing
Instructions
- Roast the corn: Preheat the oven to 450ยฐF / 230ยฐC. Line a rimmed baking sheet with parchment. In a bowl, toss the corn kernels with olive oil, 1/4 tsp kosher salt, and 1/4 tsp black pepper until lightly coated. Spread in a single layer and roast for 12โ15 minutes, stirring once at about 8 minutes, until edges are charred and fragrant. Cool on the pan for 5 minutes.
- Cook the pasta: Bring about 4 quarts of water to a rolling boil. Season with 1 tbsp kosher salt, then add the small shell pasta and cook 9โ11 minutes until al dente. Drain in a colander, rinse under cold water for 20 seconds to stop cooking, and shake off excess water.
- Whisk the creamy dressing: In a large mixing bowl, combine mayonnaise, sour cream, lime juice, apple cider vinegar, Dijon, honey, garlic, chili powder, smoked paprika, 1 tsp kosher salt, and 1/2 tsp black pepper. Whisk until smooth, glossy, and emulsified, about 45โ60 seconds.
- Assemble the salad: Add the cooled pasta, roasted corn, diced red bell pepper, scallions, jalapeรฑo, and cilantro to the bowl with the dressing. Fold gently with a spatula until every piece is well coated. Sprinkle in the cotija and fold once more. Taste and adjust seasoning with additional salt, pepper, or lime to balance richness and brightness.
- Chill and serve: For best texture, cover and chill for 15 minutes in the refrigerator (about 40ยฐF / 4ยฐC) to let flavors meld. Give the salad a quick stir before serving. Serve cool, not icy-cold, so the dressing stays creamy and aromatic.
Notes
Chefโs Tips
- Char depth: A hot pan or high oven (450ยฐF / 230ยฐC) caramelizes natural sugars in the cornโspread kernels out so they roast, not steam.
- Pasta shape matters: Shells and ditalini trap dressing beautifully; avoid long shapes that clump.
- Season in layers: Lightly season the corn, the pasta water, and the dressingโthis builds a balanced flavor without over-salting.
- Keep it creamy: Rinse pasta briefly to stop carryover cooking, then dry well so the dressing clings instead of thinning out.
- Make-ahead: Dress just before serving or reserve 2โ3 tablespoons of dressing to refresh leftovers the next day.
- Variations: Add crisp bacon, grilled chicken, or swap cotija for feta; fold in cherry tomatoes or avocado right before serving.

FAQ
Can I make this pasta salad the night before?
Yes, but hold back the cilantro, scallions, and cotija and add them right before serving. The pasta and corn can sit in the dressing overnight in the fridge; just stir in a spoonful of sour cream to loosen it up before it goes on the table.
Can I use canned corn instead of fresh or frozen?
You can, but drain and dry it very thoroughly first โ canned corn is wet and will steam rather than roast. Spread it on paper towels for a few minutes before tossing with oil, and expect slightly less char than youโd get from fresh.
How do I make this without cotija if I canโt find it?
Dry feta is the closest swap โ crumble it in the same amount but cut the salt in the dressing by about a quarter teaspoon since feta is saltier. Queso fresco also works and is milder if you want less salt overall.
Can I turn this into a main dish?
Yes โ grilled shrimp or shredded rotisserie chicken both fold in cleanly without changing the dressing. Add the protein at the same stage as the corn so it gets coated evenly, and taste for salt again after mixing since both proteins add their own seasoning.
