This corn casserole is a warm and comforting dish that’s super easy to make! It combines sweet corn, creamy goodness, and a touch of cheese for that extra yum factor.
Honestly, it’s like a hug in a bowl! I love serving it at family dinners—it always brings smiles and happy tummies. Plus, it’s such a crowd-pleaser! 😊
Ingredients & Substitutions
Whole Kernel Corn: This adds texture and pops of sweetness to your casserole. If you don’t have canned corn, frozen corn works well too! Just thaw it before using.
Creamed Corn: This ingredient creates that creamy consistency. You can substitute with homemade creamed corn or pureed corn if you’re looking for a fresh twist.
Corn Muffin Mix: Jiffy is a popular choice, but any corn muffin mix will do. If you prefer, you can make your own mix using cornmeal, baking powder, and sugar.
Sour Cream: For a lighter option, Greek yogurt is a great substitute and adds protein. If you want to avoid dairy, try a dairy-free sour cream alternative!
Cheddar Cheese: While cheese adds a nice richness, you can use a different cheese, like Monterey Jack or pepper jack, for a different flavor. You can also skip it for a dairy-free version.
Butter: If you’re looking to cut back on fat, olive oil or vegetable oil can replace butter. It’s a tasty alternative that keeps the casserole moist.
How Do I Ensure My Corn Casserole Comes Out Perfectly Cooked?
To achieve a perfectly baked corn casserole, be mindful of a few key steps. Firstly, preheat your oven properly; no one likes a baking surprise! Use a 9×9-inch dish for even cooking and ensure it’s greased to prevent sticking.
- Mix the dry ingredients thoroughly into the wet mixture. Avoid over-mixing, as this can make the casserole dense.
- When you pour the mixture into the baking dish, spread it evenly. This will help it cook uniformly.
- Check for doneness by inserting a toothpick into the center; it should come out clean. Keep an eye on the edges, too—golden brown is the goal!
Once baked, let it cool for a few minutes. This helps the casserole set up a bit before serving. Enjoy your delicious creation!

How Much Time Will You Need?
This corn casserole takes about 10 minutes of prep time and 45-50 minutes to bake. So, in under an hour, you’ll have a delightful side dish that’s perfect for any meal!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it’s heating up, lightly grease a 9×9-inch baking dish. This will help prevent sticking and make cleanup easier!
2. Mix the Base Ingredients:
In a large bowl, combine the drained whole kernel corn, creamed corn, sour cream, and melted butter. Stir everything together until it’s well mixed. You want a nice creamy base for your casserole!
3. Incorporate the Muffin Mix:
Next, add the corn muffin mix to your corn mixture. Stir until everything is combined thoroughly. If you like a touch of sweetness, feel free to add 1-2 teaspoons of sugar, along with salt and pepper to taste.
4. Add Optional Cheese:
If you’re using cheese, now’s the time to mix in the shredded cheddar cheese! Save a little bit for the top if you want a cheesy crust.
5. Bake the Casserole:
Pour the mixture evenly into your greased baking dish and smooth the top. Pop it in the oven and bake uncovered for about 45-50 minutes. You’re looking for a golden brown top and a toothpick inserted in the center should come out clean.
6. Cool and Garnish:
Once baked, let your casserole cool for a few minutes. This helps it firm up a bit. If desired, garnish with fresh parsley or chives for a pop of color and flavor!
7. Serve and Enjoy:
Serve your warm corn casserole as a comforting side dish. It’s perfect with roasted meats, barbecues, or even during the holidays! Enjoy every delicious bite!
Can I Use Fresh Corn Instead of Canned?
Absolutely! If using fresh corn, you’ll need about 3 cups. Just cut the kernels off the cob and cook them slightly to soften before adding them to the mixture. This will give a delightful fresh flavor!
How Can I Make This Casserole Gluten-Free?
To make the casserole gluten-free, substitute your corn muffin mix with a gluten-free corn muffin mix. Ensure all other ingredients, like sour cream and cheese, are also labeled gluten-free.
Can I Add Other Ingredients For Extra Flavor?
Yes! Feel free to customize your corn casserole. You can add diced jalapeños for spice, bell peppers for sweetness, or some cooked bacon for a savory touch. Just keep the overall balance in mind!
What’s the Best Way to Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave, sprinkled with a little cheese on top if you like it extra cheesy!
