A comforting and cheesy Mexican street corn casserole featuring tangy Cotija cheese, creamy sauce, and a subtle zing of lime and chili powder. Perfect for quick weeknights, potlucks, and family gatherings.

Ingredients

Scale
  • 4 cups fresh or frozen (thawed) corn kernels
  • 1 cup Cotija cheese, crumbled
  • 1/2 cup mayonnaise
  • 1/2 cup sour cream
  • 2 tablespoons fresh lime juice
  • 1 teaspoon garlic powder
  • 1 teaspoon chili powder (optional but recommended)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons butter, melted
  • 1 small jalapeño, finely chopped (optional)
  • 2 tablespoons cilantro, chopped (optional)

Instructions

  1. Preheat the oven to 375°F (190°C). Butter your 9×9-inch baking dish generously to prevent sticking and help browning.
  2. Prepare the corn kernels: cut fresh corn off the cob or thaw frozen corn and drain excess moisture.
  3. In a medium mixing bowl, combine mayonnaise, sour cream, fresh lime juice, garlic powder, chili powder, salt, and black pepper. Stir until smooth and well blended.
  4. Fold in the corn kernels, crumbled Cotija cheese, and jalapeño if using. Gently fold to combine without mashing the corn.
  5. Pour the mixture into the prepared baking dish and spread evenly. Drizzle melted butter over the top.
  6. Bake uncovered for 25 to 30 minutes until the top is golden and bubbly with browned spots.
  7. Let the casserole rest for 5 minutes after baking to set. Garnish with extra Cotija cheese and chopped cilantro if desired before serving.

Notes

Drain corn well to avoid soggy casserole. Fold gently to keep corn kernels intact. Use fresh lime juice for best flavor. Tent with foil if top browns too quickly. Can substitute Greek yogurt for sour cream and vegan mayo for dairy-free version. Feta cheese can replace Cotija if unavailable.
