This sweet corn casserole is like a warm hug on a plate! With fluffy corn, creamy goodness, and a touch of sweetness, it’s perfect for family dinners or potlucks.
What I love about this dish is how easy it is to make! Just mix the ingredients, bake, and watch it disappear. It’s a crowd-pleaser that makes your kitchen smell amazing!
Key Ingredients & Substitutions
Whole Kernel Corn: Canned corn is convenient, but you can use frozen corn if that’s what you have! Just thaw it first. Fresh corn off the cob would work too—just cook it slightly before adding.
Cream-Style Corn: This adds extra creaminess. You can use homemade cream-style corn by blending cooked corn with some milk. If you’re watching sugar, look for low-sugar options.
Cornmeal: Yellow cornmeal gives a lovely texture, but white cornmeal is a suitable substitute. You could also consider using cornbread mix if you’re in a pinch.
Sour Cream: You can swap in Greek yogurt for a lower-fat option, or use a dairy-free yogurt if needed. I’ve done this before, and it works great!
Butter: For a healthier option, swap unsalted butter with coconut oil or olive oil. It might change the taste a bit, but adds a nice twist!
How Do I Ensure My Corn Casserole is Perfectly Baked?
Baking this casserole just right is key to its fluffy texture. To avoid undercooking or overcooking, follow these simple steps:
- Set your oven to 350°F (175°C) before you start mixing. This ensures your casserole gets even cooking from the start.
- To check doneness, insert a toothpick into the center. It should come out clean, or with a few moist crumbs, but not wet batter.
- If you notice the top is browning too quickly, cover it loosely with aluminum foil to protect it while it finishes baking.
Let it cool a little before serving. This allows the flavors to settle, and the texture will firm up for easier serving.

- 1 can (15 oz) whole kernel corn, drained
- 1 can (15 oz) cream-style corn
- 1 cup yellow cornmeal
- 1 cup sour cream

How Much Time Will You Need?
This sweet corn casserole takes about 10 minutes to prepare and approximately 45 to 55 minutes to bake. So, in total, you’ll need roughly 55 minutes to 1 hour to have this delicious dish ready for your table!
Step-by-Step Instructions:
1. Prepping the Oven and Dish:
Start by preheating your oven to 350°F (175°C). While the oven is heating, grease an 8×8-inch baking dish or any similar-sized casserole dish to prevent sticking.
2. Mixing the Corn:
In a large mixing bowl, take the drained whole kernel corn and cream-style corn. Mix these two types of corn together until they are well combined.
3. Adding in Other Ingredients:
Now, it’s time to make it a casserole! Add the cornmeal, sour cream, melted butter, sugar, eggs, baking powder, and salt to the corn. Stir everything together thoroughly until the mixture is smooth and blended well.
4. Pouring into the Dish:
Once your mixture is ready, pour it into the greased baking dish. Make sure to spread it out evenly so it cooks nicely.
5. Baking:
Place your casserole in the preheated oven and bake for 45 to 55 minutes. Keep an eye on it! You’ll know it’s done when the top is golden brown and a toothpick inserted into the center comes out clean.
6. Cooling Down:
When it’s finished baking, take the casserole out of the oven. Allow it to cool for a few minutes to settle before you dig in.
7. Garnishing Before Serving:
For a pop of color and freshness, sprinkle chopped parsley or chives on top just before serving. It makes your dish look beautiful and adds a lovely flavor!
Enjoy your deliciously sweet, creamy, and slightly crispy Sweet Corn Casserole!
Can I Use Frozen Corn Instead of Canned?
Absolutely! Just make sure to thaw and drain the frozen corn before adding it to the mixture. This will help maintain the right consistency in your casserole.
How Can I Make This Corn Casserole Gluten-Free?
To make this dish gluten-free, simply substitute the yellow cornmeal with a certified gluten-free cornmeal or corn flour. This will ensure you enjoy the same great taste without the gluten!
Can I Make This Ahead of Time?
Yes, you can prepare the casserole a day in advance! Simply mix all the ingredients and store them in the greased baking dish, covered in the fridge. When ready to bake, just add a few extra minutes to the cooking time if baking straight from the fridge.
How Do I Store Leftover Corn Casserole?
Store leftover corn casserole in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply warm it in the microwave or oven until heated through. Enjoy it again as a tasty side dish!
