This 3-ingredient corn Beaumont casserole is the kind of old-school potluck side dish that earns a permanent place on the table because it is easy, comforting, and always disappears fast. With a creamy corn base and a golden baked top, it has that familiar church-supper charm that feels especially handy on busy weeknights when you want something warm and dependable without a long ingredient list.
Serve this casserole alongside baked ham, roast chicken, meatloaf, or barbecue for a simple family-style meal. It also fits right in at holiday dinners and casual gatherings, especially with green beans, a crisp salad, or sliced tomatoes to balance the rich, creamy texture.
3-Ingredient Corn Beaumont Casserole
Servings: 8
Ingredients
2 cans whole kernel corn, drained (15.25 ounces each)
1 cup sour cream
1 box Jiffy corn muffin mix (8.5 ounces)
Directions
1. Preheat the oven to 350°F and lightly grease a medium casserole dish or 8x8-inch baking dish.
2. In a large mixing bowl, stir together the drained corn, sour cream, and corn muffin mix until evenly combined.
3. Spread the mixture into the prepared baking dish and smooth the top into an even layer.
4. Bake for 35 to 40 minutes, until the center is set and the top is lightly golden around the edges.
5. Let the casserole rest for 5 to 10 minutes before serving so it can firm up slightly and scoop more neatly.
Variations & Tips
Extra Rich Version: For an even creamier casserole, use full-fat sour cream and let the baked dish rest the full 10 minutes before serving. That short cooling time helps the texture set while still staying soft and spoonable.
Make-Ahead Tip: Mix the ingredients and spread them in the baking dish a few hours ahead, then cover and refrigerate until you are ready to bake. If it goes into the oven cold, add a few extra minutes to the baking time.
Double Batch: This recipe is easy to double for a potluck or holiday meal. Bake it in a 9x13-inch dish and watch for the same signs of doneness: a set center and lightly golden top.
Texture Tip: If you prefer a smoother casserole, stir the mixture very thoroughly so the corn muffin mix fully hydrates before baking. If you like more texture, fold everything together just until combined.
