Baked Creamy Corn Casserole with Fresh Kernels

A rich and comforting corn casserole that combines fresh or frozen corn kernels with a creamy custard base made from milk, heavy cream, and eggs. The result is a golden, puffy side dish with a silky interior and lightly caramelized top. Perfect for holiday gatherings, potluck dinners, or alongside grilled meats. Optional Asiago cheese adds a subtle nutty flavor that complements the natural sweetness of the corn. This version creates a more refined texture than typical corn casseroles by using a proper custard technique.
