01 - Heat a large cast iron skillet or grill pan over high heat. Ensure the pan is well-seasoned to prevent sticking if not using oil.
02 - Add corn kernels to the preheated skillet or grill pan. Cook, stirring occasionally, until the kernels are slightly charred and tender, approximately 8-10 minutes.
03 - In a large mixing bowl, combine the mayonnaise, sour cream, minced garlic, chili powder, smoked paprika, kosher salt, black pepper, lime zest, and lime juice.
04 - Add the grilled corn kernels to the mixing bowl containing the dressing. Toss thoroughly to ensure all kernels are evenly coated.
05 - Gently stir in the crumbled cotija cheese and chopped fresh cilantro.
06 - Transfer the prepared corn to a serving dish. Garnish with additional cotija cheese, chili powder, and cilantro. Serve warm or at room temperature with optional lime wedges.
