📖 Instructions

1. Preheat your oven to 350°F (175°C). While the oven is heating, lightly grease a 9x13 inch baking dish. This step is crucial to prevent the casserole from sticking and ensures easy serving.
2. In a large mixing bowl, combine the two cans of drained whole kernel corn and the two cans of cream-style corn. Use a sturdy spoon or spatula to mix them thoroughly until well combined. Don't worry if it looks a bit chunky, that's what gives it character!
3. Add the sour cream to the corn mixture. Mix it in until it's fully incorporated and the mixture looks consistently creamy. This is where a lot of that rich, tangy flavor comes from.
4. Now, add the granulated sugar and salt. Stir well to dissolve the sugar and distribute the salt evenly. A little sweetness balances the savory corn and creates that classic casserole flavor.
5. Next, crack in the two large eggs. Whisk them lightly before adding them to the corn mixture, then stir until they are fully blended. The eggs act as a binder, helping the casserole set beautifully as it bakes.
6. Pour the entire corn mixture into your prepared 9x13 inch baking dish, spreading it evenly with your spatula. Make sure the top is relatively flat so the butter can settle nicely.
7. Take the stick of unsalted butter and cut it into about 8-10 pats or small cubes. Distribute these butter pieces evenly over the top of the corn mixture. These pats are the secret to the 'butter melt center'—they'll sink down and create pockets of deliciousness.
8. Carefully place the baking dish into the preheated oven. Bake for approximately 45-60 minutes, or until the casserole is golden brown around the edges and set in the center. A toothpick inserted into the middle should come out mostly clean, though it will still be moist. Keep an eye on it after 45 minutes to prevent over-browning.
9. Once baked to perfection, remove the casserole from the oven. Let it rest for 10-15 minutes before serving. This resting period allows the casserole to firm up slightly and makes for cleaner scoops, allowing that melted buttery goodness to truly shine.
10. Serve warm and enjoy the smiles this comforting, buttery corn casserole brings to the table! It's fantastic as a main dish accompaniment or a holiday side.
