This Jiffy Corn Casserole with sharp cheddar and a buttery Ritz cracker topping is a creamy, savory twist on the classic. It’s quick, easy, and always a crowd-pleaser—even for self-proclaimed corn casserole haters.
Don’t overmix the batter—stir just until combined. Let ingredients come to room temperature for best results. For make-ahead, assemble the casserole (without topping) the night before, refrigerate, and add topping just before baking. Leftovers keep in the fridge for up to 4 days and can be frozen for up to 3 months.
