What is corn casserole?
Corn casserole goes by several names depending on where you are, including corn pudding, corn spoonbread, and sometimes even scalloped corn. Whatever you call it, it is still a delicious dish that everyone will go back to for seconds.
So what is it? Think of corn casserole as a soft cornbread that is filled with delicious corn. It has a soft and fluffy texture that melts in your mouth, and the added corn gives it much more texture and flavor. This is not your dry, crumbly cornbread.

Ingredient notes and substitutions.
- Dairy-free corn casserole.
You can easily make this a dairy-free corn casserole. To do that, swap out the butter for a dairy-free alternative and use dairy-free greek yogurt instead of sour cream. Store-bought canned cream corn is usually dairy-free.
- Don't want to use canned creamed-style corn, or you forgot to buy it?
To make creamed-style corn, follow these steps.
- Drain a can of plain corn or defrost some frozen corn. (about 1 ½ cups)
- Puree the corn with ½ cup of milk per can worth of corn.
- Use it as if it was canned.
Use dairy-free milk to make this dairy-free creamed corn.

- Don't want a sweet corn casserole? - That's okay; you can reduce the sugar or even omit it for a more savory casserole. Don't worry; it won't affect the casserole.

Corn casserole FAQ
Most canned creamed corns are gluten-free and are usually thickened with corn starch. Major brands like Del Monte and Green Giant are gluten-free. However, it is always important to check the labels as some brands could use traditional flour as a thickener.
Yes, canned corn should be gluten-free, but it is always a good idea to check the label in case anything was added.
Cornmeal is just coarsely ground corn kernels and is naturally gluten-free. Cornmeal can become not gluten-free when it is processed on shared equipment. Brands like Bob's Red Mill sell gluten-free cornmeal. It is always a good idea to check the label to see if it is gluten-free before using it.
Jiffy makes their mixes with traditional flour, which means they are not gluten-free. At this time, they do not make a blend that is gluten-free. Brands like King Arthur and Pamelas GF both make gluten-free cornbread mixes.
Make corn casserole ahead of time.
I get it; it takes a lot of time to prep Thanksgiving and even sometimes a potluck to watch the game. Making it a gluten-free menu can mean adding even more prep. This gluten-free corn casserole is the side dish recipe you need because it's beyond easy and fast to prep.
This side dish does not work well to make ahead of time and then reheat, but there are some things you can do to help if you really want to prep ahead of time.
- Mix the dry ingredients the day before. - Measuring out the dry ingredients is what takes the most time. Measuring and mixing this ahead of time means you just have to toss in the wet ingredients and bake when you want it.
- Mix the casserole, place it in the baking dish, and cover it unbaked in the fridge overnight. - Mixing the full casserole ahead of time is not ideal, but it doesn't affect the texture too much to do so. Just make sure that you allow your baking dish to sit at room temperature, so you don't place a cold baking dish into a hot oven. Doing so can increase the chances of the baking dish cracking.
If you are short on oven space for Thanksgiving, I suggest baking this gluten-free corn casserole along with other side dishes after the turkey or ham has been removed from the oven and is resting.
Or, you can actually make this corn casserole in the crockpot.
How to make corn casserole in the crockpot.
- Mix the gluten-free corn casserole recipe just like you were going to bake it in the oven.
- Lighty grease your crockpot.
- Pour the corn casserole mixture into the crockpot.
- Cook the corn casserole on high for about 2- ½ hours or on low for about 4 hours.
Storing and reheating.
If you have leftovers of this gluten-free corn casserole, it can be stored in the fridge in a container for up to three days. To reheat it, you can either microwave individual portions for about 30-45 seconds or place the dish back into a 350-degree oven for about 10-15 minutes or until warm.
Serving suggestions.
This gluten-free side dish is usually reserved for Thanksgiving but trust me; you can eat this gluten-free corn casserole all year long. It makes a perfect pairing with a big bowl of gluten-free chili or even pair it with a delicious roasted chicken. Trust me; everyone will be asking you for the recipe if you take it to your next potluck or tailgate, and it makes a delicious gluten-free bbq side dish with ribs.
