Ingredients
  

Corn
  • 1 can (15 oz) whole kernel corn, drained
  • 1 can (14.75 oz) cream-style corn
  • 1 box (8.5 oz) corn muffin mix
  • 1 cup sour cream
  • 0.5 cup butter, melted
  • 1 cup shredded cheddar optional

Equipment

  • 1 sheet pan

Method
 

Prep and mix
  1. Preheat the oven to 350°F and grease a 9x9-inch baking dish, so the casserole releases cleanly after baking. Use a visible coating of grease on the bottom and sides as a quick visual cue.
  2. Stir together whole kernel corn, cream-style corn, corn muffin mix, sour cream, and melted butter until evenly combined. The mixture should look thick and creamy with no dry muffin mix pockets.
  3. Pour the mixture into the greased baking dish and smooth it into an even layer. Keep the surface level so it bakes uniformly.
Bake
  1. Bake for 40-45 minutes at 350°F until the top is golden and the center is set. Look for a puffed, browned top with a slight jiggle that no longer looks loose in the middle.
  2. Sprinkle with cheddar if using, then bake 5 minutes more at 350°F until melted. Watch for melted cheese pooling slightly across the surface.
Rest and serve
  1. Rest the corn casserole for 10 minutes before serving to help the center finish setting. The texture should cut cleanly instead of running.

Notes

Pro tip: use a greased 9x9-inch dish and keep the oven fully preheated so the top puffs instead of staying flat. Store leftovers covered in the refrigerator up to 3 days; reheat in the oven or microwave until warmed through. Freezing is not recommended for the best creamy texture. For a lighter option, swap sour cream for low-fat sour cream (similar thickness) without changing the bake time.
