Corn Casserole

Corn casserole is the side dish that disappears first at every holiday table. Sweet corn kernels and creamed corn baked into a soft, golden cornbread base, somewhere between a pudding and a spoonbread.

It goes together in one bowl, needs no special technique, and works just as well on a Tuesday as it does at Thanksgiving. We keep it on rotation because it pairs with nearly everything.

Why This Recipe Works

Three things keep this version consistent, even when you are cooking for a crowd.

• Two forms of corn build depth. Whole kernels give bursts of sweet crunch while cream-style corn adds body and moisture to the batter, so the casserole stays soft inside without being soupy.
• Sour cream keeps it tender for hours. The fat and acidity slow starch firming, which means the casserole stays creamy on a buffet line instead of turning rubbery as it cools.
• Cornbread mix handles structure and flavor. It brings the leavening and cornmeal in one pour, so the casserole rises slightly and sets with a golden, cakey top.

Ingredient Notes

Simple pantry ingredients, but a couple of choices shape the result.

• Cornbread mix: The small 8.5 oz box is the standard here. Any brand works, though the sweetness varies slightly between them.
• Whole kernel corn: Drain it well. Extra liquid thins the batter and can leave the center undercooked.
• Cream-style corn: This is canned corn in a thick starchy sauce, and it is the main binder in the casserole. Do not substitute regular corn and cream.
• Sour cream: Full-fat gives the richest texture. Greek yogurt is a reasonable stand-in, though the tangier flavor comes through.
• Cheddar cheese: Sharp cheddar melts into the batter and adds a savory edge that balances the sweet corn. Shred from a block for the smoothest melt.

How to Make Corn Casserole

The short version. Full amounts and times are in the recipe card below.

Step 1: Mix the batter. Stir together both cans of corn, the cornbread mix, sour cream, melted butter, and eggs until just combined. Fold in the cheese. A few lumps are fine.

Step 2: Pour and spread. Transfer the batter into a greased 9x13 baking dish and smooth the top with a spatula.

Step 3: Bake until golden and set. Bake at 350°F for 45 to 55 minutes. The top should be deep golden and the center should feel firm when pressed lightly. A toothpick comes out clean or with just a few moist crumbs. Rest 10 minutes before serving.

Variations

The base takes swaps without losing its texture. Here are the ones we come back to.

• Jalapeno cheddar: Fold in 2 tablespoons of minced pickled jalapenos and swap half the cheddar for pepper jack.
• Bacon and chive: Stir 4 strips of crumbled cooked bacon and 2 tablespoons of chopped fresh chives into the batter.
• Sour cream and onion: Add 2 tablespoons of dry onion soup mix to the batter for a savory, onion-forward version.
• Mexican street corn style: Mix in 1/4 cup of crumbled cotija, 1 teaspoon of chili powder, and a squeeze of lime juice.

Storage & Reheating

Cool leftovers to room temperature, then cover and refrigerate within 2 hours. Corn casserole keeps in the fridge for 3 to 4 days.

Reheat individual servings in the microwave for 60 to 90 seconds, or warm a larger portion covered in a 325°F oven for 15 to 20 minutes. The casserole freezes well for up to 2 months. Wrap tightly in foil and plastic, then thaw overnight in the fridge before reheating.

FAQ

Can I make corn casserole ahead of time?

Yes. Mix the batter, pour it into the dish, cover, and refrigerate up to 24 hours. Bake it straight from the fridge and add 5 to 10 extra minutes since it starts cold. Watch for the golden top and firm center as your cues.

Can I double this recipe?

Double all ingredients and use two 9x13 dishes or one large roasting pan. Bake time stays about the same as long as the batter depth is similar. Avoid stacking it deeper in one smaller dish, which extends the bake time and risks a raw center.

Why did my corn casserole sink in the middle?

Usually underbaking. The cornbread mix leavens the batter, and if the center has not fully set, it collapses as it cools. Bake until a toothpick inserted in the center comes out without wet batter, and let it rest in the pan.

Is corn casserole the same as corn pudding?

They are close relatives. Corn pudding tends to be softer and more custard-like, with more eggs and dairy. Corn casserole uses cornbread mix for structure, which gives it a firmer, cakey texture. Both land on the same holiday tables.

What to Serve With

Corn casserole is a natural side for roasted or grilled proteins. It sits well alongside our tater tot casserole for a crowd-sized spread, or next to chicken broccoli casserole when you want two baked dishes that cover a whole dinner table.
