This sweet corn casserole is incredibly easy to make with simple ingredients like canned corn, corn muffin mix, sour cream, and cheddar cheese, with a subtle kick from jalapeño. It’s a crowd-pleasing side dish perfect for potlucks, holidays, or any gathering.
For best results, shred your own cheese from a block. Let the casserole cool for at least 10 minutes before serving to allow it to set. To make ahead, assemble the casserole (minus the final cheese topping) up to 24 hours in advance, refrigerate, then add cheese and bake, adding about 10 minutes to the baking time. For a deeper flavor, toast the diced jalapeño in a dry skillet for 2 minutes before adding.
