Tip: save now, cook later.Creamy Corn Casserole for Thanksgiving is a comforting and delicious side dish that brings a little sweetness and a lot of creaminess to the table. It’s made with tender corn kernels, creamy cheese, and a smooth, buttery base that comes together in a golden, bubbly casserole that everyone will want to try.
I love making this dish because it’s so simple but feels special. The blend of sweet corn and cheesy creaminess always reminds me of cozy family meals. I usually make it the day before and let it chill in the fridge overnight — it helps the flavors come together perfectly and makes it super easy to pop into the oven right before dinner.
For serving, I like to scoop big portions onto plates alongside turkey and mashed potatoes. It’s one of those comforting dishes that feels just right for holiday dinners. Plus, it’s great for left-overs the next day! Whenever I serve it, I’m always happy when there’s enough to go around because it seems like everyone asks for seconds.
Key Ingredients & Substitutions
Corn Kernels & Creamed Corn: Both add texture and sweetness. Fresh corn is great in season, but frozen works just as well. If you want a smoother casserole, add a bit more creamed corn.
Sour Cream: This gives creaminess and a slight tang. You can swap it with Greek yogurt to lighten the dish or use a dairy-free alternative if needed.
Butter: Melting butter adds richness. Use salted butter but watch salt amounts, or swap with margarine for a dairy-free version.
Corn Muffin Mix: This is key for the soft, bready texture. If you can’t find it, use regular cornmeal with a bit of baking powder as a substitute but the rise may differ.
Cheddar Cheese: Sharp cheddar adds a nice punch of flavor. Mild cheddar works too, or try a blend with Monterey Jack or mozzarella for a milder taste.
How Can I Avoid Overmixing the Casserole Batter?
It’s tempting to stir everything thoroughly, but overmixing can make your casserole tough or gummy.
- Combine wet ingredients first, then gently fold in dry ingredients along with corn and cheese.
- Mix just until everything is combined and no large pockets of dry mix remain.
- A few small lumps are okay – they bake out and keep the texture light.
- Using a spatula instead of a whisk helps control how much you mix.
Taking care with mixing ensures your casserole turns out tender and creamy every time!

Equipment You’ll Need
- 9×9-inch baking dish – perfect size for even baking and easy serving.
- Large mixing bowl – roomy enough to combine all ingredients without spilling.
- Measuring cups and spoons – helps get the right amounts for best texture and flavor.
- Rubber spatula – great for folding ingredients without overmixing.
- Oven mitts – essential for safely handling the hot casserole dish.
Flavor Variations & Add-Ins
- Add diced jalapeños or a pinch of cayenne pepper for a spicy kick that balances the sweetness.
- Mix in cooked, crumbled bacon for smoky, salty flavor and added crunch.
- Try swapping sharp cheddar for pepper jack cheese to add a gentle heat and creamy melt.
- Stir in chopped green onions or fresh herbs like parsley or chives for fresh, bright notes.
Creamy Corn Casserole for Thanksgiving
Ingredients You’ll Need:
Main Ingredients:
- 2 cups corn kernels (fresh or frozen)
- 1 cup creamed corn
- 1 cup sour cream
- 1/2 cup unsalted butter, melted
- 1 package (8.5 oz) corn muffin mix (such as Jiffy)

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and around 45-50 minutes to bake. Allow an extra 5 minutes to cool before serving. So, plan on roughly 1 hour from start to finish.
Step-by-Step Instructions:
1. Prepare Your Oven and Pan:
Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking dish or similar casserole dish lightly to prevent the casserole from sticking.
2. Mix the Ingredients:
In a large mixing bowl, combine the corn kernels, creamed corn, sour cream, and melted butter. Stir these together gently.
Next, add the corn muffin mix, shredded sharp cheddar cheese, eggs, milk, salt, and black pepper. Stir just until everything is combined — avoid overmixing to keep the casserole light and fluffy.
3. Bake the Casserole:
Pour the mixture into your prepared baking dish and spread it evenly. Place it in the oven and bake for 45 to 50 minutes, or until the casserole is set and the top turns golden and bubbly.
4. Let It Rest and Serve:
Take the casserole out of the oven and let it sit for about 5 minutes to set. If you’d like, sprinkle fresh thyme leaves on top for a pop of color and fresh flavor. Serve warm alongside your Thanksgiving feast and enjoy!
Can I Use Frozen Corn Instead of Fresh?
Absolutely! Just make sure to thaw the frozen corn and drain any excess water before adding it to the casserole to avoid extra moisture.
Can I Make Creamy Corn Casserole Ahead of Time?
Yes, you can prepare the casserole mixture a day in advance and keep it covered in the fridge. When ready, bake it fresh before serving to maintain the best texture.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
Can I Substitute the Corn Muffin Mix?
If you don’t have corn muffin mix, you can try using cornmeal with a bit of baking powder as a backup, but the texture might be slightly different.
