01 - Bring a large pot of salted water to a rolling boil. Add the rotini or penne and cook according to package directions until al dente. Drain thoroughly and rinse under cold running water to halt cooking. Set aside 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, tossing occasionally, until lightly charred and smoky spots appear. Remove from heat and let cool.
03 - In a large mixing bowl, combine the diced chicken, halved cherry tomatoes, finely diced red onion, charred corn kernels, jalapeño (if using), and chopped cilantro. Toss gently to distribute evenly.
04 - In a separate medium 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 blended.
05 - Add the cooled pasta to the chicken and vegetable mixture. Pour the dressing over the top and toss thoroughly, ensuring every component is evenly coated with the creamy elote-style dressing.
06 - Just before serving, scatter the crushed 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.
