Ingredients
For the Casserole
- 1 can (15.25 ounces) whole-kernel corn, drained
- 1 can (14.75 ounces) cream-style corn
- 1 package (8 ounces) Jiffy corn muffin mix
- 1 cup sour cream
- 6 tablespoons salted butter, melted
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 cup shredded cheddar cheese
- 2 large eggs, optional
- 2 tablespoons chopped fresh parsley, optional
Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.
A slightly smaller dish can also be used if you prefer a thicker casserole, although the baking time may need to be adjusted.
Step 2: Combine the Corn
Drain the whole-kernel corn thoroughly.
Add it to a large mixing bowl along with the cream-style corn.
Stir gently until combined.
The whole corn provides texture and sweetness, while the cream-style corn helps create the casserole’s moist consistency.
Step 3: Add the Remaining Ingredients
Add the corn muffin mix, sour cream, melted butter, salt, and black pepper.
If using eggs, add them now.
Stir everything together just until combined.
Don’t worry if there are a few small lumps. Avoid overmixing the batter.
Step 4: Add the Cheese
Fold the shredded cheddar cheese into the mixture.
Sharp or mild cheddar can be used depending on your preference.
For a more pronounced cheesy flavor, you can combine cheddar with Monterey Jack.
Step 5: Transfer to the Baking Dish
Pour the mixture into the prepared baking dish.
Spread it evenly with a spatula.
If desired, sprinkle a little additional shredded cheese over the top for a golden, cheesy crust.
Step 6: Bake
Bake for approximately 45–55 minutes, or until the center is set and the top is lightly golden.
The center should remain moist and tender but should not look liquid or raw.
If you’ve added extra cheese to the top, it should be melted and lightly browned.
Step 7: Rest Before Serving
Remove the casserole from the oven and let it rest for 5–10 minutes.
This allows the center to firm up slightly and makes the casserole easier to serve.
Garnish with fresh parsley if desired.
Serve warm.
Tips for the Best Buttery Corn Casserole
Drain the corn well
Excess liquid can make the casserole too loose or watery.
Use real butter
Melted butter gives the casserole much of its rich, comforting flavor.
Don’t overmix
Stir just until the ingredients are combined to maintain the tender texture.
Don’t overbake
The casserole should be moist and soft rather than dry and cake-like.
Let it rest
Allowing the casserole to sit for a few minutes after baking helps it set before serving.

Make-Ahead Instructions
Corn casserole is an excellent make-ahead side dish.
You can mix the ingredients several hours before baking and keep the uncooked casserole refrigerated.
When you’re ready to bake, remove it from the refrigerator while the oven preheats.
If the casserole is very cold, it may require a few additional minutes in the oven.
Storage
Allow leftover casserole to cool before transferring it to an airtight container.
Refrigerate promptly.
Reheat individual portions in the microwave or oven.
For a larger portion, cover the casserole with foil and warm it in a 325–350°F (165–175°C) oven until heated through.
Can You Freeze Corn Casserole?
Yes, although the texture may change slightly after freezing because of the dairy ingredients.
Allow the casserole to cool completely, wrap it tightly, and place it in a freezer-safe container.
Thaw in the refrigerator before reheating.
Frequently Asked Questions
Is corn casserole the same as corn pudding?
The names are sometimes used interchangeably, although recipes vary. Corn pudding is generally softer and more custard-like, while corn casserole can have a firmer, more cornbread-like texture.
Can I use frozen corn?
Yes. Thaw the corn completely and drain away excess liquid before adding it to the batter.
Can I use Greek yogurt instead of sour cream?
Yes. Plain Greek yogurt can replace sour cream, although the finished flavor and texture may be slightly different.
Can I make it without cheese?
Absolutely. Simply leave out the cheddar. The corn, sour cream, butter, and corn muffin mix will still create a rich and flavorful casserole.
Why is my corn casserole watery?
Too much liquid, insufficient baking time, or poorly drained corn can cause a watery casserole. Drain the corn well and make sure the center is fully set before removing it from the oven.
Can I use a smaller baking dish?
Yes. A smaller dish will create a thicker casserole, but it may require additional baking time.
