This creamy, cheesy corn casserole uses Jiffy mix, sour cream, and sharp cheddar for a moist, custard-like texture. It’s the perfect side dish for potlucks, holidays, or any comfort food craving.
For best results, shred your own cheddar cheese (pre-shredded contains anti-caking agents that affect melting). Use room temperature eggs to prevent butter from seizing. Let casserole rest after baking to set properly. If top browns too quickly, tent with foil for last 10 minutes.
