My aunt brings this to every single gathering and the pan is scraped clean before we even sit down. I still can't believe it only takes 4 ingredients.

This southern 4-ingredient baked corn casserole is the kind of dish that disappears before anyone remembers to take a proper photo. It’s based on the classic Midwestern–meets–Southern church potluck casserole: sweet corn, creamed corn, a boxed cornbread mix, and sour cream, all bound together with butter. The result is a golden, gently crisped top with a rich, custardy center that feels both nostalgic and indulgent. It’s the sort of reliable, no-fuss recipe an aunt brings to every gathering because she knows the pan will be scraped clean before you even sit down.

Serve this casserole warm, straight from the glass baking dish, alongside roast chicken, baked ham, or a simple pan-seared pork chop. It’s especially good on holiday tables next to turkey and gravy, where its sweetness balances savory mains and salty sides like green beans or collard greens. A crisp salad with a tangy vinaigrette or some simply roasted vegetables will cut through the richness nicely. Leftovers, if you manage to have any, reheat well and pair beautifully with a fried egg on top for a very comforting breakfast or brunch.

Servings: 8

1/2 cup (1 stick) unsalted butter, melted and slightly cooled

Preheat your oven to 350°F (175°C). Lightly grease a 2-quart or 8x8-inch glass casserole dish; this helps the edges crisp and release easily.

Melt the butter in a small saucepan or in the microwave, then let it cool for a couple of minutes so it’s warm but not hot. This keeps the casserole from separating.

In a large mixing bowl, whisk together the melted butter and sour cream until smooth and fully combined.

Add the drained whole kernel corn and the cream-style corn to the bowl. Stir until the corn is evenly distributed in the creamy mixture.

Sprinkle the cornbread muffin mix over the corn mixture. Using a spatula or wooden spoon, gently fold until no dry pockets of mix remain. The batter will be thick and lumpy from the corn—that’s exactly what you want.

Transfer the mixture to the prepared glass casserole dish, smoothing the top into an even layer so it bakes uniformly and browns nicely around the edges.

Bake, uncovered, for 40–50 minutes, or until the top is golden brown, the edges are deeply caramelized and crisp, and the center is set but still slightly jiggly and creamy. A toothpick inserted near the center should come out mostly clean, with a bit of moisture but no wet batter.

Remove the casserole from the oven and let it rest for at least 10 minutes. This short resting time allows the buttery, creamy center to settle so you can scoop neat portions while still keeping that luscious, spoonable texture.

Serve warm, scooping generous spoonfuls from the pan. Expect it to vanish quickly—this is one of those dishes people hover around while it’s still bubbling.

Because this recipe is intentionally only four ingredients, think of variations as optional tweaks rather than requirements. If you’d like a slightly lighter texture, you can swap half of the sour cream for plain Greek yogurt without changing the basic character of the dish. For a touch of heat, fold in a small can of diced green chiles or a pinch of cayenne with the corn. A handful of shredded sharp cheddar over the top during the last 10 minutes of baking adds a gratinéed layer without interfering with the creamy center. If you prefer a firmer, more bread-like casserole, bake it in a slightly larger dish so the layer is thinner, and extend the baking time by 5–10 minutes for extra browning and structure. Leftovers can be cooled, covered, and refrigerated for up to 3 days; reheat, covered with foil, at 325°F until warmed through, then uncover for a few minutes to re-crisp the edges.
