Corn casserole is a creamy, savory baked side made with just 5 ingredients — Jiffy corn muffin mix, whole kernel corn, creamed corn, sour cream, and butter — baked at 350°F until golden on top and set underneath. It’s the dish that shows up on nearly every Thanksgiving table, and for good reason: it’s fast, it’s foolproof, and everyone goes back for seconds.
I’ve made this one for more holidays than I can count, and I’ll give you the classic version exactly the way I make it, plus how to make it without Jiffy if you can’t find it, how to fix it if it comes out too wet or too dry, and how to prep the whole thing ahead so you’re not juggling one more dish on Thanksgiving morning.

What Is Corn Casserole?
Corn casserole is a baked side dish built on a corn muffin mix base, folded with whole kernel corn, creamed corn, and sour cream, then baked until it sets into something between a cornbread and a pudding. It’s a Thanksgiving and Christmas staple in most American kitchens, but honestly, it earns a spot at cookouts, potlucks, and weeknight dinners year-round too. It sits in an interesting spot on the corn-side spectrum — firmer than a corn pudding, softer than a slice of cornbread — and we’ll sort out exactly where the lines are a little further down.
The 5 Ingredients You Need
The classic version comes down to five ingredients, and each one is doing a specific job:
- Jiffy corn muffin mix — just the dry box, not a prepared muffin batter. This is what gives the casserole its cornbread-like structure and a hint of sweetness.
- Whole kernel corn, drained — adds texture and pops of whole corn throughout. Draining it matters more than people think (more on that in the troubleshooting section).
- Creamed corn — this is the moisture and body of the dish. Don’t drain this one; you want all of it.
- Sour cream — adds richness and keeps the crumb tender instead of dry.
- Butter, melted — rounds everything out and helps the top turn golden.
That’s it. No eggs required for the classic spoonable version — though I’ll walk you through when you might want to add one.
How to Make Corn Casserole
This is a one-bowl recipe, and it comes together in minutes:
- Mix. In a large bowl, stir together the dry corn muffin mix, drained whole kernel corn, creamed corn, sour cream, and melted butter until just combined.
- Pour. Transfer the mixture into a greased 8×8-inch baking dish. Doubling the recipe? Use a 9×13-inch dish instead.
- Bake. Bake at 350°F for 45–55 minutes.
- Rest. Let it sit for 10 minutes before serving. This isn’t optional — it’s part of how the casserole finishes setting.
How do you know it’s done? Look for a golden top and a center that’s set, not jiggly or wet-looking. If you want to double-check, an internal temperature of 165°F or higher confirms it’s fully cooked. The resting time afterward firms it up further, so don’t skip it even if it looks ready straight out of the oven.
Egg or No Egg? (Choose Your Texture)
This is a real fork in the road, and most recipes don’t tell you it’s a choice at all.
No egg is the classic 5-ingredient version, and it bakes up soft, creamy, and spoonable — closer to a corn pudding in texture. This is the version most people picture when they think “corn casserole,” and it’s what I make by default.
With 2 eggs added to the same base, the casserole turns firmer and more sliceable. It holds its shape when you cut into it instead of scooping, which some people prefer for a more structured side dish. This is also the direction Southern-style versions tend to lean.
Neither is more “correct” — it comes down to whether you want something you scoop or something you slice. If you do add eggs, know that egg-based casseroles should reach a minimum internal temperature of 160°F to be fully and safely cooked through, so don’t pull it early just because the top looks golden.
Can You Make Corn Casserole Without Jiffy?
Yes — and this is worth knowing whether Jiffy isn’t sold near you, you’re out of a box, or you’d just rather make it from scratch.
Jiffy corn muffin mix is doing three jobs at once: it supplies the cornmeal and flour structure, a leavening agent so the casserole rises slightly, and a touch of sugar for sweetness. To replace one box, combine:
- ⅔ cup cornmeal
- ⅓ cup all-purpose flour
- 2 tablespoons sugar
- 1 tablespoon baking powder
- ¼ teaspoon salt
Whisk that together and use it in place of the box, measure for measure, in the recipe above. The result is very close to the original, though you have more control here — cut the sugar back if you prefer a less sweet casserole, or add a bit more if you like it closer to cornbread. If you want a version built entirely from scratch rather than as a mix substitute, that’s a deeper project worth its own recipe — we’ll link that one here once it’s live.
Why Is My Corn Casserole Wet / Dry / Not Set? (Troubleshooting)
This is the section that actually solves the problem most people run into. Corn casserole texture depends on a handful of levers — how well you drained the corn, how long it baked, whether you rested it, even the pan you used — and once you know what each one does, you can fix (or prevent) almost any texture issue.
| Problem | Likely Cause | Fix |
|---|---|---|
| Wet or mushy center | Undrained whole kernel corn, watery creamed corn, underbaked, or not rested | Drain the whole kernel corn well, bake a little longer, and let it rest a full 10 minutes before cutting |
| Too dry or crumbly | Overbaked, too much mix relative to corn, or missing the creamed corn | Pull it from the oven a little earlier next time, and don’t skimp on the creamed corn — it’s your main source of moisture |
| Won’t set / stays loose | Pan is too large or shallow for the volume, or oven is running cool | Bake in an 8×8-inch dish for the standard recipe, verify your oven temperature, and consider adding an egg for extra structure |
| Too dense | Overmixed batter, or too much dry mix | Stir just until the ingredients are combined — don’t overwork it |
| Pale, un-browned top | Oven running low, or rack positioned too low | Finish with 1–2 minutes under the broiler, watching closely |
If you take one thing from this table: draining the whole kernel corn (but never the creamed corn), giving it the full bake time, and letting it rest afterward will solve the vast majority of texture complaints on their own.
Corn Casserole vs Corn Pudding vs Cornbread
These three get mixed up constantly, so here’s the quick distinction:
- Corn casserole is built on a corn muffin mix base and bakes up creamy but set — the texture we’ve been describing throughout this guide.
- Corn pudding is a milk-and-egg custard base, often without any muffin mix at all, and it bakes up noticeably softer and looser than a casserole.
- Cornbread casserole (sometimes called a corn spoonbread cousin) leans firmer and more bread-like, closer to a dense cornbread than a scoopable side.
- Corn soufflé and spoonbread sit at the lighter, eggier end of the spectrum, with a texture closer to a savory soufflé.
If a recipe you’re reading calls itself “corn casserole” but describes something loose and custardy, it’s really closer to corn pudding — the name gets used loosely online, but the ingredients tell you which one you’re actually making.
Variations
Once you’ve got the base down, it’s easy to riff on it.
Cheesy Corn Casserole
Stir 1 cup of shredded cheddar into the batter and sprinkle another ½ cup over the top before baking, for a melty, golden finish.
Cream Cheese Corn Casserole
Fold in 4 ounces of softened cream cheese along with the sour cream for a noticeably richer, tangier casserole. This is an underrated upgrade that doesn’t get much attention, but it makes a real difference.
Southern-Style Corn Casserole
Add an egg and a cup of shredded cheddar to the base for a firmer, richer, more Southern take on the dish — the direction cooks like Paula Deen have leaned toward, with egg and cheese building a more structured casserole than the classic spoonable version.
Jalapeño, Bacon, or Sweet
Stir in diced pickled or fresh jalapeños for heat, crumbled cooked bacon for smokiness, or an extra tablespoon of sugar if you like your casserole on the sweeter side.
Crockpot and Mexican Street Corn
Two more directions worth knowing about: a crockpot version (handy for freeing up oven space on Thanksgiving) and a Mexican street corn–inspired version with lime, cotija, and chili powder. We’ll link both of these full recipes here once they’re live.
Make It Ahead for Thanksgiving
Corn casserole is genuinely make-ahead friendly, which makes it a good pick when your oven is already fighting for space with a turkey.
Assemble ahead: Mix the casserole, cover, and refrigerate for up to 48 hours unbaked. Let it sit at room temperature for 30–60 minutes before it goes in the oven so it bakes evenly.
Bake ahead and reheat: You can also bake it fully in advance, then reheat, covered, at 300°F for 10–20 minutes until warmed through.
Oven-space strategy: If your oven is maxed out with the turkey, a crockpot version of this casserole is worth having in your back pocket — it frees up the oven entirely and keeps the side warm on its own timeline.
Transport and doubling: For a crowd, double the recipe into a 9×13-inch dish rather than two separate 8x8s — it bakes more evenly and travels better in one piece. It also freezes well, for up to 3 months, if you want to get ahead on holiday prep even further out.
What to Serve It With
Corn casserole pairs naturally with turkey, ham, or roast chicken, and it holds its own next to other Thanksgiving classics — try it alongside green bean casserole, sweet potato casserole, and homemade stuffing. If you’re planning dessert too, it leaves plenty of room for sweet potato pie or easy apple pie later in the meal.
Outside the holidays, it’s just as at home next to barbecue, a bowl of chili, or as a simple weeknight side.
Storage & Leftovers
Store leftover corn casserole covered in the refrigerator for 3–4 days. Reheat gently, either in a 300°F oven or in a skillet over low heat, until warmed through. When reheating any leftovers, including casseroles, the safe target is an internal temperature of at least 165°F, checked with a food thermometer.
Corn casserole also freezes well for up to 3 months. One note: versions made with egg tend to hold their texture better after freezing and reheating than the very soft, no-egg version, which can turn slightly more watery once thawed.
Frequently Asked Questions
What are the 5 ingredients in corn casserole?
Jiffy corn muffin mix, whole kernel corn, creamed corn, sour cream, and butter — mixed and baked at 350°F.
Can you make corn casserole without Jiffy?
Yes. Replace the box with ⅔ cup cornmeal, ⅓ cup flour, 2 tablespoons sugar, 1 tablespoon baking powder, and ¼ teaspoon salt.
Why is my corn casserole mushy or not setting?
Usually undrained whole kernel corn, not enough bake time, or skipping the rest period. Drain the corn well, bake the full time, and let it rest 10 minutes before serving.
What’s the best Southern-style corn casserole?
Southern versions typically add an egg and shredded cheddar to the classic base for a firmer, richer casserole — a direction associated with cooks like Paula Deen.
What’s the difference between corn casserole and corn pudding?
Corn casserole is built on a corn muffin mix; corn pudding is a milk-and-egg custard, which bakes up softer and looser.
Can I make corn casserole ahead of time?
Yes — assemble it up to 48 hours ahead and refrigerate unbaked, or bake it fully ahead and reheat at 300°F before serving.
Can I make corn casserole in a crockpot?
Yes, and it’s a smart move when your oven is full on Thanksgiving. We’ll link our full crockpot version here once it’s live.
Do I need to drain the corn?
Drain the whole kernel corn, but not the creamed corn — the creamed corn is your moisture source and should go in as-is.
You’ll sometimes see this dish tied to names like Jackie Kennedy or Dolly Parton online; there’s no verified recipe behind those claims, so we won’t repeat them here as fact.
