Preheat the oven to 375F and move the rack to the middle position. Grease a 9x13 casserole dish.
In a medium-to-large mixing bowl, add the eggs (beat them with a fork), then the sour cream, creamed corn, canned corn, and melted butter. Stir until smooth.
Stir in the corn muffin mix (make sure it's smooth but don't over-mix).
Pour the batter into the casserole dish and smooth it out.
Bake, uncovered, for 40-50 minutes or until the middle has set and the top is golden (I bake mine for 45). Keep in mind that ovens and baking dishes can vary so timing isn't exact. I use a ceramic casserole dish.
Rest 10 minutes prior to serving. The texture of corn casserole is moist and creamy, so it won't be as firm as cornbread. I find it easiest to use a serving spoon to scoop it out into individual portions.
