Creamy Corn Casserole for Thanksgiving is a comforting side dish that’s sweet, tender, and perfectly creamy. It combines fresh or canned corn with a smooth, cheesy base that just melts into each bite. The texture is soft but with a little bit of crisp on top, making it a favorite alongside turkey and all the traditional fixings.

I love making this casserole every year because it feels like a warm hug on a plate. What I really like is how easy it is to prepare—just mix a few simple ingredients, pop it in the oven, and wait for that beautiful golden top. I find that using a little bit of cream cheese or sour cream really adds extra creaminess and richness that everyone seems to enjoy.

For serving, I usually bring it out right alongside the stuffing and mashed potatoes. It’s one of those dishes that kids and adults alike go back for seconds on without even thinking. And honestly, I’ve noticed leftover corn casserole tastes just as good the next day, which makes it a handy addition to the holiday spread or even a simple family dinner anytime.

Key Ingredients & Substitutions for Creamy Corn Casserole

Corn: Using a mix of whole kernel and cream-style corn adds both texture and creaminess. If fresh corn is available, you can use about 2 cups freshly cut kernels for a fresher taste.

Cornmeal: This gives the dish a gentle grainy texture and helps it set. You can substitute with fine polenta if you want a slightly smoother texture.

Sour Cream: Sour cream adds richness and moisture. For a lighter version, plain Greek yogurt works well and keeps the creaminess.

Butter: Melted butter adds flavor and helps the casserole brown nicely. You can use olive oil or a dairy-free butter substitute if needed.

Eggs: Eggs bind everything together and help with structure. For an egg-free version, try using a flax egg or a commercial egg replacer.

How Do You Get the Perfect Golden Brown Top Without Drying Out the Casserole?

Baking just right makes all the difference. Here’s how to get that beautifully browned top while keeping the inside soft and creamy:

• Use the middle rack of your oven for even heat around the casserole.
• Grease your dish well to prevent sticking and encourage browning.
• Check doneness by inserting a toothpick; it should come out clean, but the casserole still feels moist.
• If the top browns too fast, tent it loosely with foil for the last 10-15 minutes to avoid burning.
• Let the casserole rest 10 minutes after baking—it firms up and is easier to slice.

Equipment You’ll Need

• 9×9-inch baking dish – perfect size for even cooking and easy serving.
• Mixing bowls – one large for corn and one medium for dry ingredients keeps things organized.
• Whisk or spoon – for mixing the batter smoothly without lumps.
• Measuring cups and spoons – to get your ingredients just right.
• Oven mitts – to safely handle the hot casserole dish when taking it out of the oven.

Flavor Variations & Add-Ins

• Add 1 cup shredded cheddar or pepper jack cheese to the batter for a richer, cheesy taste.
• Mix in 1/2 cup chopped jalapeños or green chilies for a little spicy kick.
• Stir in 1 cup cooked and crumbled bacon for smoky flavor that pairs well with corn.
• Fold in 1/2 cup chopped green onions or fresh herbs like parsley for a fresh, savory note.

Creamy Corn Casserole for Thanksgiving

Ingredients You’ll Need:

Main Ingredients:

• 1 can (15 oz) whole kernel corn, drained
• 1 can (14.75 oz) cream-style corn
• 1 cup yellow cornmeal
• 1/2 cup all-purpose flour
• 1/4 cup granulated sugar
• 1 tablespoon baking powder
• 1/2 teaspoon salt
• 1 cup sour cream
• 1/2 cup unsalted butter, melted
• 2 large eggs, lightly beaten
• Fresh thyme or parsley leaves for garnish (optional)

How Much Time Will You Need?

This creamy corn casserole takes around 15 minutes to prepare and about 45-55 minutes to bake. After baking, we recommend letting it cool for about 10 minutes so it sets well and is easier to serve. In total, plan for roughly 1 hour from start to finish.

Step-by-Step Instructions:

1. Prepare the Oven and Dish:

Start by preheating your oven to 350°F (175°C). Grease a 9×9-inch baking dish or a similar casserole dish so the casserole won’t stick once baked.

2. Mix the Corn and Dry Ingredients:

In a large bowl, combine the drained whole kernel corn with the cream-style corn. In a separate bowl, whisk together the cornmeal, flour, sugar, baking powder, and salt. Pour the dry mix into the corn and stir gently to combine.

3. Add Wet Ingredients and Combine:

Next, stir in the sour cream, melted butter, and lightly beaten eggs. Mix everything well until you have a smooth, even batter with little to no lumps.

4. Bake the Casserole:

Pour the batter evenly into your greased baking dish. Place it in the preheated oven and bake for 45 to 55 minutes. The top should turn a warm golden brown, and a toothpick inserted in the middle should come out clean when it’s done.

5. Let It Cool and Serve:

Remove the casserole from the oven and let it cool for about 10 minutes before serving. This helps the casserole set and makes it easier to cut and serve. Optionally, garnish with fresh thyme or parsley leaves for a pop of color and fresh flavor.

Can I Use Frozen Corn Instead of Canned Corn?

Yes! Just thaw the frozen corn completely and drain any excess moisture before mixing it in. This helps prevent the casserole from becoming too watery.

Can I Make This Casserole Ahead of Time?

Absolutely! Prepare the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. Bake it when ready, adding a few extra minutes if baking cold from the fridge.

How Should I Store Leftovers?

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through.

Can I Add Cheese or Other Ingredients?

Yes, adding 1 cup of shredded cheese like cheddar or pepper jack adds great flavor. You can also mix in chopped jalapeños, cooked bacon, or green onions for extra taste and texture.
