Melt butter or warm olive oil in a large skillet or cast-iron pan over medium-high heat. Add corn kernels and sauté for 5 to 7 minutes, stirring occasionally, until tender and slightly charred. If using frozen corn, cook until heated through and lightly browned.
02 -
Remove pan from heat and allow corn to cool for several minutes to avoid curdling the dressing.
03 -
In a large mixing bowl, stir together mayonnaise, sour cream or crema, 1/4 cup crumbled cotija cheese, lime juice, chili powder, and smoked paprika if using, until well combined and smooth.
04 -
Add the cooled corn, chopped cilantro, and minced jalapeño if using to the bowl with the dressing. Stir gently to ensure all corn is evenly coated.
05 -
Taste, then add salt and freshly ground black pepper as needed. Use caution with additional salt since cotija cheese is naturally salty.
06 -
Transfer salad to a serving bowl. Garnish with extra crumbled cotija cheese, a sprinkle of chili powder, and more fresh cilantro. Serve immediately or chill for at least 30 minutes to allow flavors to meld.
