Scalloped corn casserole takes just an hour to bake, and you can put it together the night before. This time-saving hack helps to make it the perfect side dish for any special dinner.
As a bonus, our corn casserole has one secret ingredient that makes it better than the rest. I’m not very good at keeping cooking secrets so let me just say there may be some cheese involved!
What is it?
Scalloped corn casserole is a must-make holiday side dish in our family. It is my favorite Thanksgiving corn recipe which is why I’ve been making it for 40-some years.
My mom always made it for holidays but it is my sister-in-law who brought this old-fashioned corn casserole to an entirely new level.
This is a great side dish to bring if you are a guest at Thanksgiving, Christmas, or Easter dinner.
Ingredients and notes
Our scalloped corn casserole has a base of egg and cheese. Those two things help form a custard around the sweet corn. They also put the “scallop” in the casserole that bakes to a savory perfection.
Corn – Use fresh, frozen, or canned. If your corn is frozen or canned, be sure to drain it before adding it to the other ingredients.
Cheddar Cheese – This is the secret ingredient that makes our scalloped corn better than the rest. The cheese adds a creamy flavor and texture that is the perfect match to the other ingredients. It also helps to bind and hold a scalloped corn casserole together.
Pro Kitchen Tip – Use shredded cheese for this corn casserole but do yourself a favor and buy a block of cheese and shred it yourself. The pre-shredded cheese has potato starch and other filler in it, which is why it doesn’t melt as evenly. It also doesn’t taste as good, in my humble opinion!
If you don’t like mushrooms, leave them out! The same goes for the onion and sweet bell pepper. Make it your own!
How to make it
This is how I like to make my scalloped corn but you can personalize it to your taste. Another reason to love this easy and versatile dish.
One thing that makes this corn casserole so great is that it is super easy to put together. I always use frozen corn since this is usually made for a holiday side dish. There isn’t a lot of fresh sweet corn to be had in Wisconsin, after August!
- Dice whatever vegetables you want to use, and melt some butter in a skillet.
- Saute the veggies over medium-low heat until they are soft.
- Combine the remaining ingredients in a mixing bowl and mix them all up, then add to skillet.
- At this point you can either seal and refrigerate overnight until ready to bake. Or bake as directed below. Be sure to allow the sauteed vegetables to cool before mixing with the other ingredients, if storing in the fridge.
- Bake the scalloped corn at 400° F. for 45 to 60 minutes, uncovered.
- Do not over-crowd the saute pan when sauteing the vegetables. This will result in “sweating” the vegetables, or cooked in their own juices. You’ll get better flavor with a slow saute!
- For a little extra-flavor, brown about 6 oz of pork sausage to stir into the mixture.

Common recipe questions
You can put this scalloped corn together a day ahead of time. Just seal and refrigerate until you’re ready to bake. This makes is a great make-ahead Thanksgiving corn recipe!
Like our crock pot scalloped potatoes, you can make this corn recipe in a slow cooker as well! Spray the inside with a non-stick coating. Then add the other ingredients. Slow cook for 2 to 3 hours until it reaches an internal temperature of 165°. (Remember, there is an egg in this recipe.) Here is some useful information about egg safety.
I like to saute the vegetables before adding them to the crockpot for this recipe. Check the sides often to make sure they are not getting too brown because slow cookers can vary in temperature.
We always make this corn casserole for our holiday dinners. Serve it with all the fixings, plus the main entrées.
Scalloped Corn with Crackers
Instead of using bread crumbs, you can make this corn casserole with crackers.
- For a more buttery flavor, use club crackers or Ritz crackers in the casserole and as a topping.
- To add some crunchy texture and a bit more salt, use some crushed saltine crackers in this corn casserole.
Instead of cheddar cheese, you can add a little kick this scalloped corn by use pepper jack cheese (use the same amount.)
You don’t need to add the mushrooms, onion, or sweet bell peppers, in case you don’t like any of these ingredients. The scalloped corn will still be delicious!
To Make this Gluten Free – Use cornstarch instead of flour and substitute some almond flour for the breadcrumbs. Both lend body to the casserole and the almond flour with give a mild, you some mild and nutty undertones.
