Corn casserole is a warm, comforting dish that combines sweet corn, creamy ingredients, and a touch of cheese. It’s like a hug on your plate!
This dish is perfect for family dinners or potlucks. The best part? It’s super easy to make and always a crowd-pleaser. I like to serve it with a dollop of sour cream on top. Yum!
Ingredients & Substitutions
Corn: Both the whole kernel corn and creamed corn add great texture and sweetness. If you have fresh corn, you can use about 4 ears of corn, boiled and cut off the cob. Frozen corn can also work well in place of canned, just thaw before using.
Corn Muffin Mix: Jiffy is a popular choice, but you can substitute any corn muffin mix if needed. You can also make your own mix by combining flour, cornmeal, sugar, baking powder, and salt.
Sour Cream: This adds creaminess and tang to the casserole. If you want a lower-fat option, you can use Greek yogurt. For a dairy-free alternative, try coconut yogurt.
Cheddar Cheese: While optional, shredded cheddar gives extra flavor. Feel free to substitute with mozzarella for a milder taste or leave it out for a lighter version.
Fresh Herbs: Thyme and parsley add a nice touch. If you don’t have fresh herbs, dried herbs can work, but use sparingly as they’re more concentrated.
How Do I Ensure My Corn Casserole Sets Perfectly?
To achieve that ideal texture in your corn casserole, it’s important to mix the ingredients well without overmixing. Overmixing can incorporate too much air and lead to a gummy texture. Gently stir just until everything is combined.
- Preheat the oven properly to create a nice crust.
- Use a toothpick tester — it should come out clean when the casserole is done. If it’s a bit gooey, give it more time.
- Resting for about 10 minutes after removing it from the oven helps it set nicely and makes it easier to serve.

How to Make Delicious Corn Casserole
Ingredients You’ll Need:
For the Casserole:
- 1 can (15 oz) whole kernel corn, drained
- 1 can (14.75 oz) creamed corn
- 1 cup corn muffin mix (such as Jiffy)
- 1 cup sour cream
- 1/2 cup (1 stick) unsalted butter, melted
- 1 cup shredded cheddar cheese (optional)
- 1 teaspoon baking powder
- 2 large eggs
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
For Garnish (Optional):
- Fresh thyme or parsley
How Much Time Will You Need?
This hearty corn casserole takes about 15 minutes to prep. You will then need to bake it for 45 to 55 minutes. After baking, let it rest for 10 minutes before serving. So, in total, you’re looking at around 1 hour and 20 minutes from start to finish!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). While it’s heating, grease a 9×13-inch baking dish or a similar size, so your casserole doesn’t stick when it’s done.
2. Mix the Ingredients:
In a large mixing bowl, add the drained whole kernel corn, creamed corn, corn muffin mix, sour cream, melted butter, (optional) shredded cheddar cheese, baking powder, eggs, salt, and black pepper. Give everything a good stir until it’s all mixed together. Be careful not to overmix—just stir until combined!
3. Pour and Garnish:
Pour the corn mixture into your prepared baking dish. Spread it out evenly. If you’d like, you can sprinkle some fresh thyme leaves or chopped parsley on top for extra flavor and a lovely presentation.
4. Bake:
Place the baking dish in the oven and bake it uncovered for about 45 to 55 minutes. You’ll know it’s ready when the top is golden brown, and a toothpick inserted in the center comes out clean.
5. Cool Down:
Once it’s done baking, take it out of the oven and let the corn casserole sit for about 10 minutes. This step is essential as it helps the casserole set up nicely, making it easier to serve.
6. Serve and Enjoy:
Now it’s time to serve your warm corn casserole as a comforting side dish. It pairs beautifully with any meal. Enjoy the creamy, slightly sweet, and savory flavors!
Can I Use Frozen Corn Instead of Canned?
Absolutely! If using frozen corn, make sure to thaw it first before adding it to the mixture. This helps maintain the right texture in your casserole.
How Do I Store Leftover Corn Casserole?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat it in the microwave or oven until warmed through. If reheating in the oven, cover it with foil to prevent it from drying out.
Can I Make This Corn Casserole Ahead of Time?
Yes, you can prepare the casserole mixture in advance and refrigerate it (covered) for up to 24 hours before baking. When you’re ready to bake, just pour it into the greased dish and pop it in the oven! You may need to adjust the baking time slightly if starting from cold.
What Can I Substitute for Sour Cream?
If you don’t have sour cream, you can use Greek yogurt for a similar tangy flavor. For a dairy-free option, try coconut yogurt or a nut-based yogurt alternative!
