A creamy, cheesy, savory-sweet side dish that is simple enough for a busy weeknight and elegant enough for any holiday table.

Each summer I pick up a couple (…or four) bushels of delicious corn from one of my favorite local farms. This particular farm is about an hour and a half away from our home, but it is so worth the drive! We get to enjoy the quiet morning drive in the country, meet some fantastic farmers and workers, and enjoy the deliciousness of locally grown sweet corn.
It is a lot of work to process the corn once we get it home and it usually takes us a few days to get it all squared away. Thankfully it becomes a family project that makes it a bit more fun. I like to preserve the corn in multiple ways, freeze-drying, canning, and freezing. This recipe works great for fresh, home-canned, freeze-dried, or store-bought.
Why You’ll Love This Creamy Corn Au Gratin
This recipe is one of our favorites, especially around the holidays. It starts with that delicious corn and butter, the perfect seasoning blend, cream, and lots of cheese. The best part is that it comes together quickly and is from oven to table in about 30 minutes!
What to Serve with Creamy Corn Au Gratin
On a busy weeknight, I like to pair this easy side dish with a slow-cooker favorite, Salisbury Steak, classic meatloaf, or homemade fried chicken. It’s also a luxurious addition to the holiday table with sides like roasted potatoes, homemade mac and cheese, and honey butter yeast rolls.

What Ingredients Are Needed To Make Creamy Corn Au Gratin
Butter - The real stuff will give you the most flavor for your dollar.
Corn - Fresh, frozen, home-canned, or freeze-dried. Whatever you have works. If you’re using freeze-dried, you’ll want to ensure that it is fully rehydrated before using. Be sure to drain any excess liquid.
Seasonings - Simple is the secret to this recipe. You want the flavor of the corn to be the star. I stick to basics like garlic powder, onion powder, salt, pepper, and crushed red pepper flakes.
Heavy Cream - This will help to give that creamy, decadent flavor. Whole milk or even 2% will work here as well, but you may need to increase the amount of flour to help create a thicker sauce.
Flour - Just a general all-purpose flour will do the trick. It will act as a thickener for the sauce.
Cheese - We love freshly grated Parmesan and Asiago in this dish. You could also use a mild cheddar or for a little kick, Pepperjack.
