4-Ingredient Corn Casserole
Servings: 8
Ingredients
1 box (8.5 ounces) corn muffin mix
Directions
1. Preheat the oven to 350°F and lightly grease an 8x8-inch baking dish or similar small casserole dish.
2. In a medium mixing bowl, stir together the corn muffin mix, drained whole kernel corn, creamed corn, and sour cream until evenly combined.
3. Spread the batter evenly into the prepared baking dish, smoothing the top so it bakes up evenly.
4. Bake for 45 to 50 minutes, or until the top is golden brown and the center is set.
5. Let the casserole rest for 5 to 10 minutes before scooping and serving so it can firm up slightly and stay nice and fluffy.
Variations & Tips
Butter boost: For an even richer casserole, stir in 1/2 cup melted butter with the other ingredients. It adds extra flavor and gives the edges a deeper golden finish.
Cheesy version: If your family loves a savory twist, mix in 1 cup shredded cheddar cheese before baking. This makes the casserole a little heartier and especially nice with ham or chili.
For picky eaters: If you want a smoother texture, give the batter a gentle stir just until combined and make sure the whole kernel corn is well drained. That helps the casserole stay soft and fluffy without becoming too wet.
Make-ahead tip: You can mix the batter a few hours ahead, cover it, and refrigerate it until ready to bake. Give it a quick stir before spreading it in the dish.
Holiday serving tip: This casserole stays warm well, so it is a wonderful choice for buffet-style meals. If needed, cover it loosely with foil after baking and keep it in a low oven for a short time before dinner.
