01 - Bring a large pot of salted water to a boil. Cook rotini or penne according to package directions until al dente. Drain and rinse under cold running water to halt cooking. Set aside and allow to cool completely.
02 - Heat a dry large skillet over medium-high heat. Add corn kernels and sauté without oil for 3 to 5 minutes, tossing occasionally, until lightly charred and caramelized 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 mayonnaise, sour cream, fresh lime juice, smoked paprika, chili powder, garlic powder, salt, black pepper, and crumbled Cotija cheese until smooth and well blended.
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 crushed corn tortilla chips over the salad for a crispy finish. Garnish with additional crumbled Cotija, fresh cilantro, and an extra squeeze of lime if desired. Serve chilled or at room temperature.
