01 - Bring a large pot of salted water to a boil and cook the rotini or penne according to package directions until al dente. Drain thoroughly and rinse under cold running water to halt cooking. Set aside and allow to cool completely.
02 - Heat a large dry skillet over medium-high heat. Add the corn kernels in an even layer and sauté without oil for 3 to 5 minutes, stirring occasionally, until lightly charred and smoky spots appear. Remove from heat and let cool.
03 - In a large mixing bowl, combine the cooked chicken, halved cherry tomatoes, diced red onion, charred corn, diced jalapeño (if using), and chopped cilantro. Toss gently to distribute evenly.
04 - In a separate bowl, whisk together the mayonnaise, sour cream, fresh lime juice, smoked paprika, chili powder, garlic powder, salt, black pepper, and crumbled Cotija cheese until smooth and well combined.
05 - Add the cooled pasta to the chicken and vegetable mixture. Pour the dressing over the top and toss thoroughly until every component is evenly coated with the creamy elote-style dressing.
06 - Just before serving, sprinkle the crushed corn tortilla chips over the salad for a crispy finish. Garnish with additional crumbled Cotija cheese, fresh cilantro leaves, and an extra squeeze of lime if desired. Serve chilled or at room temperature.
