Corn Casserole

There are side dishes that complete a meal — and then there are side dishes that people specifically show up for. This corn casserole is the second kind. Soft, custardy, golden on top, and tasting like the very best version of cornbread and creamy corn pudding all in one — made with just six ingredients, one bowl, and almost zero effort. This is the recipe that disappears before anything else on the holiday table, every single time.

One hour, six ingredients, and a result that earns compliments from everyone who tries it. This classic belongs on your table all year long.

Why You’ll Make This Again

Corn casserole sits in a beautiful middle ground between cornbread and corn pudding — soft and custardy in the center with a lightly golden, slightly firm top that gives way to the most comforting, creamy interior with every single scoop. The cream-style corn keeps it rich and moist while the whole kernel corn adds pops of texture throughout. And the sour cream — that is the secret ingredient that makes this casserole more tender, more tangy, and more deeply satisfying than any version made without it. Six ingredients, one bowl, and something that tastes like it took all day to make.

This is the ultimate fall and winter comfort side dish. It belongs at Thanksgiving, Christmas, Easter, and every potluck and Sunday dinner in between. Once you bring it somewhere, you will be asked to bring it everywhere.

How This Comes Together

Combine everything in one bowl, stir until smooth, pour into a baking dish, and bake. That is genuinely the entire recipe from start to finish. The beauty of this casserole is that it requires almost no technique — if you can stir ingredients together in a bowl, you can make this perfectly every single time. The oven does all the real work, transforming that simple batter into something golden, custardy, and completely irresistible in just 45 minutes.

What You’ll Need

Six simple pantry ingredients. This is the kind of recipe you can pull together on short notice because everything stays shelf-stable until you need it.

• 1 box corn muffin mix (about 8.5 oz)
• 1 can cream-style corn (15 oz)
• 1 can whole kernel corn, drained (15 oz)
• 2 large eggs
• 1/2 cup (1 stick / 0.25 lb) unsalted butter, melted
• 1 cup sour cream

Step-by-Step Directions

1. Preheat oven to 350°F. Lightly grease a 9×13-inch baking dish and set aside.
2. In a large mixing bowl, combine the corn muffin mix, cream-style corn, drained whole kernel corn, eggs, melted butter, and sour cream. Stir until smooth and well blended.
3. Pour the mixture into the prepared baking dish and spread evenly with a spatula.
4. Bake for 45 minutes until the top is lightly golden and a toothpick inserted into the center comes out clean.
5. Remove from oven and allow to cool slightly for 5–10 minutes before serving so the casserole sets up and scoops cleanly.

How to Serve It

Scoop generous portions straight from the baking dish into wide bowls or onto plates while still warm. It looks beautiful served alongside roasted turkey, glazed ham, or a classic pot roast — the sweet, creamy corn flavor pairs perfectly with any savory main course you put next to it. For a holiday spread, set the whole baking dish on the table between the mashed potatoes and the green beans and watch it hold its own against every other dish. A sprinkle of fresh chives or a small pat of butter melting over each warm scoop makes the presentation simple but genuinely lovely.

Leftovers & Storage

Cover the casserole tightly and store in the fridge for up to 4 days. Reheat individual portions in the microwave for 60–90 seconds or in the oven at 325°F for 10–15 minutes until warmed through. This casserole reheats beautifully and the flavor actually deepens and improves overnight — leftovers the next day taste just as good as freshly baked. It also freezes well for up to 2 months — portion into individual freezer-safe containers before freezing and thaw overnight in the fridge before reheating in the oven. Make it ahead and freeze it for a stress-free holiday side dish that is ready whenever you need it.

Make It Even Better (Pro Tips)

• Don’t drain the cream-style corn — all that liquid is part of what makes this casserole so rich and moist throughout.
• Do drain the whole kernel corn thoroughly — excess liquid from the can makes the batter too wet and affects the final texture of the casserole.
• Make sure your butter is fully melted and slightly cooled before adding to the bowl — hot butter added to eggs can begin to cook them and affect the texture of the finished batter.
• Don’t overmix — stir until just combined and smooth. Overmixing develops gluten in the muffin mix and can make the casserole slightly tough instead of tender and custardy.
• Check for doneness at the 40-minute mark — every oven is slightly different and overbaking dries out the center and removes that beautiful custardy quality that makes this dish so special.
• Grease the baking dish very generously — this casserole has a tendency to stick around the edges if the dish isn’t thoroughly coated.
• Let it rest the full 5 to 10 minutes before scooping — it firms up significantly as it cools slightly and serves much more cleanly in neat, satisfying portions.

Easy Ways to Change It Up

• Cheesy version: Stir 1 cup of shredded cheddar cheese into the batter before baking and sprinkle another 1/2 cup over the top for a rich, cheesy corn casserole that is even more indulgent and crowd-pleasing.
• Jalapeño version: Fold in 2 tablespoons of diced pickled jalapeños for a gentle heat that contrasts beautifully with the sweetness of the corn and the richness of the sour cream.
• Bacon addition: Stir 4 strips of crumbled cooked bacon into the batter for a smoky, savory depth that makes this casserole even more hearty and satisfying.
• Honey butter finish: Mix a tablespoon of honey into the melted butter before adding to the batter for a subtly sweeter, more dessert-like corn casserole that works beautifully alongside savory holiday mains.
• Smaller dish option: Bake in an 8×8-inch dish for a thicker, more custardy, pudding-like result — increase the baking time by 10 minutes and check for doneness with a toothpick.

Quick Questions

Can I make corn casserole without Jiffy mix?

Yes. Make a simple homemade substitute by whisking together 1/2 cup all-purpose flour, 1/2 cup yellow cornmeal, 3 tablespoons granulated sugar, 1 tablespoon baking powder, and 1/4 teaspoon salt. Use this in place of the boxed corn muffin mix in the same quantity and the casserole will taste just as delicious and homemade as ever.

Can I make this casserole ahead of time?

Absolutely — and it’s one of the best make-ahead side dishes for holiday cooking. Mix the batter, pour into the greased baking dish, cover tightly with plastic wrap, and refrigerate for up to 24 hours before baking. When ready to cook, remove the plastic wrap and bake as directed, adding 5 extra minutes to account for the cold batter. The result is just as golden, custardy, and delicious as baking it fresh on the day.

Why is my corn casserole too wet or runny?

The most common causes are underbaking or whole kernel corn that wasn’t drained properly before adding to the batter. Make sure to drain the whole kernel corn very thoroughly and bake until the toothpick test comes out completely clean with no wet batter attached. If the center still seems very loose at the 45-minute mark, cover loosely with foil and bake for an additional 10 minutes before testing again.
