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.

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.
