I first made this Easy Corn Casserole Recipe for a church potluck, and I honestly didn’t expect it to disappear before the main dish even hit the table. It’s the kind of side that looks like it took real effort, but I’m just stirring everything in one bowl and letting the oven do the rest. I make it with a box of Jiffy corn muffin mix, two kinds of corn, sour cream, and butter, no eggs, no fuss.
If you’re already planning a full spread, I usually pair this with something like a cheesy chicken and gravy bake or a lighter side like a fresh lentil salad to balance out the richness. Once you try this corn casserole recipe, I promise it earns a permanent spot on your table too.

Cooking Time
- Prep Time: 5 minutes
- Cook Time: 45-50 minutes
- Total Time: 50-55 minutes
Ingredients
- 1 box (8 oz) Jiffy corn muffin mix — use only the dry mix, skip the egg and milk printed on the box
- 15 oz whole kernel corn, drained — gives the casserole its soft, bite-sized texture
- 15 oz creamed corn, not drained — this is what makes the whole dish creamy and rich
- 1 cup sour cream — let it sit at room temperature so it blends in smoothly
- ½ cup butter, melted — adds that golden top and buttery flavor throughout
Note: This recipe serves 8 people as a side dish.
Equipment You’ll Need
- Large mixing bowl — for combining all five ingredients in one go
- 8×8-inch baking dish — the right size for even baking and a creamy center
- Measuring cups — to keep ingredient ratios accurate
- Rubber spatula — for folding the batter and scraping the bowl clean
- Oven mitts — because that dish comes out hot and bubbly

How to Make an Easy Corn Casserole Recipe?
I love this recipe because it really only takes two real steps from bowl to oven. There’s no layering, no pre-cooking anything, and no fancy technique required. Here’s exactly how I put mine together every single time.
Preheat and Prep the Pan
I start by preheating my oven to 350ºF so it’s fully hot by the time my batter is ready. While that’s warming up, I spray my 8×8-inch baking dish with cooking spray so nothing sticks later. This small step saves me from fighting with the pan when it’s time to serve.
Mix the Batter
In a large bowl, I add the dry Jiffy mix, drained whole kernel corn, undrained creamed corn, sour cream, and melted butter all at once. I stir everything together until it’s just combined and no dry streaks remain. I never add the egg or milk listed on the Jiffy box, since the sour cream and creamed corn already give it plenty of moisture.
Pour and Bake
I pour the mixed batter straight into my prepared baking dish and smooth the top with my spatula. Then it goes into the oven, uncovered, for about 45 to 50 minutes. I’m watching for a golden top and a center that no longer looks wet when I nudge the pan.
Check for Doneness
I know my casserole is ready when the internal temperature hits at least 165ºF and the top is lightly golden brown. A gentle jiggle in the center is completely normal, since this dish is meant to be soft and creamy, not firm like cornbread.
Rest Before Serving
Once it’s out of the oven, I let my casserole rest for about 10 minutes before cutting into it. This resting time lets it firm up slightly, which makes serving so much cleaner. I finish mine with a pinch of salt and pepper right before bringing it to the table.
Additional Tips for Making This Recipe Better
I’ve made this corn casserole more times than I can count, and these are the little things I’ve learned along the way:
- I always bring my sour cream to room temperature first, because cold sour cream doesn’t blend in as smoothly and can leave lumps.
- I never skip draining the whole kernel corn, since extra liquid is usually what makes my casserole turn out watery.
- I sometimes swap in about 12 ounces of frozen sweet corn instead of canned, and it works beautifully.
- I like doubling this recipe in a 9×13 pan for bigger gatherings, just knowing it needs about 15 extra minutes in the oven.
- I always let mine rest the full 10 minutes, because cutting into it too early makes it look messier than it actually is.
Common Mistakes to Avoid
Here are the slip-ups I made early on, and how I fixed them for good:
- I used to add the egg and milk from the Jiffy box instructions, which made my casserole too wet. I stick to the dry mix only now.
- I once forgot to drain the whole kernel corn, and it turned my casserole soupy. I always drain it well before mixing.
- I pulled mine out of the oven too early a couple of times, thinking the jiggle meant it wasn’t done. I bake until it hits 165ºF in the center instead.
- I didn’t grease my baking dish once, and half the casserole stuck to the bottom. I always spray it generously now.
- I tried rushing the rest time right out of the oven, and serving was a mess. I give it the full 10 minutes before scooping.
How to Serve Easy Corn Casserole?
I usually scoop this straight from the baking dish with a big spoon, letting each serving show off that golden top and creamy center. A light garnish of chopped fresh parsley or sliced green onion adds a nice pop of color against the yellow casserole.
It’s an easy side for a Sunday pot roast, grilled chicken, or a full holiday spread, and I often set it right next to a heartier main like a comforting chicken and grain bowl so the table feels balanced between rich and fresh flavors. For potlucks, I just keep it in the baking dish, wrap it loosely in foil, and let people help themselves family-style.

Variations
I love how forgiving this recipe is when I want to switch things up:
- Corn Casserole with Eggs — stir in 2 eggs for a slightly firmer, more sliceable texture.
- Cheesy Corn Casserole — mix in ½ to 1 cup of shredded cheddar cheese for extra richness.
- Sweet Corn Casserole — add ¼ to ½ cup sugar if you prefer a dessert-like, cornbread-style sweetness.
- Spicy Corn Casserole — toss in diced jalapeños for a little kick alongside the creamy base.
- Dairy-Light Version — use light sour cream and reduce the butter slightly without losing much texture.

Make Ahead and Storage
I often mix this casserole up to 48 hours in advance, cover the unbaked dish with plastic wrap, and keep it in the fridge until I’m ready to bake. I just pull it out about 30 to 60 minutes before baking so it’s not going into the oven ice cold.
For leftovers, I store mine in an airtight container in the fridge for up to 3 to 4 days. I reheat individual portions in the microwave, or warm the whole dish in a 350ºF oven until it’s heated through.
I don’t recommend freezing the full unbaked casserole, since the texture can turn watery once thawed. Leftover baked portions do freeze okay in an airtight container for a few weeks if needed.

- It’s incredibly easy to make. I only need one bowl, five ingredients, and about five minutes of actual prep work before it goes in the oven.
- It’s endlessly versatile. I can dress it up with cheese and eggs for a firmer bite, or sweeten it for a dessert-style treat.

FAQs
Can I make corn casserole without Jiffy mix?
Yes, you can swap in any 8.5-ounce corn muffin mix, or make a homemade blend using cornmeal, flour, sugar, baking powder, and salt in similar proportions.
Why is my corn casserole watery or mushy?
This usually happens when the whole kernel corn isn’t drained well or the casserole comes out of the oven before the center fully sets at 165ºF.
Can I make this corn casserole ahead of time?
Yes, I mix it up to 48 hours ahead, keep it covered in the fridge, and let it sit out briefly before baking as usual.
Can I double this recipe for a larger group?
Absolutely, I just bake it in a 9×13-inch pan instead of an 8×8, and give it about 15 extra minutes in the oven.
How long does leftover corn casserole last in the fridge?
I keep mine in an airtight container in the refrigerator for up to 3 to 4 days, reheating portions in the microwave or oven as needed.
