Method
Prep and preheat
- Preheat oven to 350°F and grease a 9x9-inch baking dish so the casserole releases easily.
Mix
- Stir together whole kernel corn, cream-style corn, corn muffin mix, sour cream, and melted butter until evenly combined and no dry mix remains.
Bake
- Pour the mixture into the greased baking dish and spread it out evenly.
Finish baking
- Bake 40-45 minutes at 350°F until golden on top and set in the center; the edges should look set while the center springs back slightly.
Optional cheddar melt
- Sprinkle with shredded cheddar if using and bake 5 minutes more until melted and lightly bubbling.
Rest
- Rest 10 minutes before serving so the center firms up into a sliceable, custardy texture.
Notes
For clean slices, let the casserole rest the full 10 minutes before cutting. Refrigerate leftovers in an airtight container for up to 3-4 days; reheat portions in the microwave at 50% power until warmed through. Freezing is not recommended for the best texture, but if needed, freeze in portions and reheat gently. For a lighter option, use reduced-fat sour cream and butter.
