Easy Gluten-Free Corn Casserole (No Jiffy Mix Needed)
This gluten-free corn casserole is creamy in the middle, golden at the edges, and disappears fast. It uses a good gluten-free cornbread mix so you get the same sweet corn flavor and tender crumb without any wheat.
If you grew up with the classic Jiffy version and thought you had to give it up, this recipe gets you right back to that same cozy dish, just as simple as the original.
What Makes This Corn Casserole a Keeper
It comes together in one bowl and bakes into a spoonable side that works with almost anything. The creamed corn and sour cream keep it moist all the way through, while the butter gives the top that lightly crisp, toasted edge.
I make this one for holidays, potlucks, and weeknight dinners because it holds well and reheats like a dream. The taste is sweet corn, a little savory from the salt and eggs, and rich without being heavy.
Ingredients
- 1 can (14.75 oz) creamed corn: the base that gives it that classic soft, pudding-like texture
- 1 can (15.25 oz) whole kernel corn, drained: adds little pops of texture
- 1 cup sour cream: full-fat keeps the casserole creamy and rich
- ½ cup unsalted butter, melted and cooled slightly: brings the buttery flavor and helps the top set
- 2 large eggs, lightly beaten: binds everything together
- 1 box (about 8.5 oz) gluten-free cornbread mix: I use Krusteaz or Bob’s Red Mill; both work well here
Variations / Substitutions
- Dairy-free: use a thick plant-based sour cream alternative and a good vegan butter. The texture will be a little softer but still good.
- Less sweet version: look for a gluten-free cornbread mix labeled “honey-free” or “unsweetened” if you prefer a more savory casserole.
- Add heat: stir in a small can of diced green chiles or a pinch of cayenne with the wet ingredients.
- Cheesy version: fold in 1 cup shredded sharp cheddar before baking for a cheesy corn casserole.
- Herb finish: scatter chopped chives or parsley on top right before serving.

How To Make Gluten-Free Corn Casserole
Step 1: Whisk the Wet Ingredients
Heat the oven to 350°F (175°C). In a large mixing bowl, whisk together the 1 cup sour cream, ½ cup melted butter, and 2 beaten eggs until smooth. Stir in the whole can of creamed corn and the drained whole kernel corn until everything is evenly combined.
The mixture will look loose and pale yellow at this point. A few streaks of butter are fine; they’ll disappear in the oven.
Step 2: Fold in the Dry Mix
Pour the gluten-free cornbread mix over the wet ingredients. Using a spatula, gently fold until no dry pockets remain. Stop as soon as the batter comes together — overmixing can make the finished casserole dense instead of tender.
The batter will be thick but pourable, with little flecks of corn throughout. If it seems too stiff, trust the process; the creamed corn releases moisture as it bakes.
Step 3: Bake the Casserole
Lightly grease an 8-by-8-inch or 9-by-9-inch baking dish. Scrape the batter into the dish and spread it even with the spatula. Bake on the center rack for 45 to 50 minutes, until the top is deep golden and the center barely jiggles when you nudge the pan.
The edges will pull slightly away from the sides, and the middle should read about 200°F on an instant-read thermometer if you want to check. The surface gets a nice, lightly crackled top that crisps up around the rim.
Step 4: Scoop and Serve
Let the casserole rest for 5 to 10 minutes before serving. This short pause helps it set just enough to spoon out in neat scoops without falling apart. Serve it warm right from the dish with a big spoon, and watch it go fast.
Tips for the Best Gluten-Free Corn Casserole
- Let the melted butter cool for a few minutes before whisking in the eggs so you don’t scramble them.
- Check your cornbread mix: some gluten-free mixes already contain salt and sugar, so taste the batter before adding extra salt.
- For a deeper golden top, run the dish under the broiler for 1 to 2 minutes at the very end, watching closely so it doesn’t burn.
Bake times by dish size:
| Dish Size | Bake Time |
|---|---|
| 8×8-inch | 45 to 50 mins |
| 9×9-inch | 40 to 45 mins |
| 9×13-inch (doubled) | 35 to 40 mins |
Storing Leftover Corn Casserole
- Refrigerate: cover tightly and refrigerate for up to 4 days. The texture stays creamy.
- Reheating: warm individual portions in the microwave for 30 to 60 seconds, or reheat the whole dish covered with foil at 300°F for 15 minutes.
What Goes Well With Gluten-Free Corn Casserole
This dish shines next to anything with a little smoky or savory contrast. Try it with barbecue chicken, or glazed ham where the sweet corn offsets the tangy sauce. It’s also right at home beside roast turkey or meatloaf for a classic comfort plate.
Frequently Asked Questions
Can I use fresh corn instead of canned?
Yes, you can. Use about 1½ cups of fresh corn kernels cut from the cob in place of the drained whole kernel corn, and keep the creamed corn as written.
What gluten-free cornbread mix works best?
Krusteaz and Bob’s Red Mill are both reliable and easy to find. Avoid any mix that contains sugar alcohols or has a noticeable bean aftertaste, as that will change the flavor.
Can I make this ahead of time?
You can assemble the batter and refrigerate it, covered, up to 1 day ahead. When ready to bake, let the dish sit at room temperature while the oven heats, then bake as directed, adding 5 extra minutes if needed.
Why did my casserole come out dry?
Overbaking is the usual culprit. Start checking at 40 minutes, and pull it when the center is still slightly jiggly; it will set as it rests.
