This easy crockpot corn casserole recipe is cheesy and perfect vegetarian side dish at Thanksgiving or Christmas! Moist sweet Jiffy corn pudding dish you’ll love.

This easy crockpot corn casserole recipe is always a Thanksgiving and Christmas side dish hit. It’s actually so good I make it throughout the year. Leftovers are amazing too! 😉 It’s one of our favorite side dish crockpot recipes here on The Typical Mom blog for sure. (originally published 8/17, affiliate links present)
Slow Cooker Corn Casserole
Each holiday I make this cream corn casserole recipe but this year I wanted to figure out how much time it would take in my slow cooker and Instant Pot as well.
If you’ve never tried this tasty creamed corn side dish it is one of my favorites.
FIRST – You should sign up for my free newsletter so you get new posts emailed to you twice a week and never miss out on anything! Let’s talk a little bit about slow cooking shall we?? First off I have a few different varieties and I love them all. Each one has an occasion to be used like….
- This is my favorite 6 quart programmable one with a locking lid so it’s great for bringing to a potluck too.
- If you just want to serve a few appetizers you should get this one that sit side by side one another.
- I prefer not to use liners, but rather just spray olive oil inside before adding my food for easier cleanups.
Let me give you a peek of my pretty thang I bought recently. It goes with my kitchen so I can just leave it out on the countertop all the time. 😉

Jiffy Corn Casserole Crockpot
Made with Jiffy cornbread mix it is inexpensive and quick to throw together.
There’s a bit of sweetness to it that everyone loves too. I use my 6 or 8 quart crockpot for this so the mixture can spread out and cook evenly.
- Like other casseroles the edges will get a bit more done than the center so keep that in mind.

Crockpot corn casserole
Of course you’ll need your favorite slow cooker. A larger size is better so batter can spread out and cook evenly.
- Jiffy corn muffin mix
- Sugar
- Sour cream
- Eggs
- Corn and cream corn in a can
Drained diced chiles are optional but I think it is a great add in for sure. If you are serving a crowd you might want to make a batch of this and buy more boxed mix to cook a pot full of Crockpot cornbread.

Crock Pot Recipe for Corn Casserole
Cheese on top is optional but not for us. We add a bit inside the mix and on top at the end.
If you want the top to be a bit golden and brown you can. Just stick the whole Crock under the broiler for a few minutes.
Some non stick cooking spray or liners are great to use inside your pot for an easier cleanup later

Why do I love crockpot side dishes? Because during the holiday season you have a lot going on in your oven. Being able to eliminate even one dish is always helpful. It is kinda’ a dump and go side too because it can be served right out of your Crock!
What about doubling this recipe?
- I haven’t done this but I suppose you could. Cook time would probably need to increase and I’d use at least an 8 quart slow cooker so the mix spreads out and it cooks evenly.
If you’re having a rather large holiday meal you might need to try this.
Slow cooker corn casserole recipe
- Shredded cheddar cheese or pepper jack cheese on top
- Sprinkle on top for the last 30 minutes of cook time so it melts
- As I said I’ve added 1 can of drained diced chiles into the mix before
- You could finely dice a seeded jalapeno into the mix for heat
Some have added a bit of room temperature cream cheese to their mix. I haven’t tried this yet.
Some people call this corn pudding, others say Jiffy corn casserole. They’re all very similar with slight tweaks.

Here are the basic instructions to follow:
- Mix all ingredients together in a bowl. It will be a bit chunky but that is okay.
- Spray your Crockpot with non stick spray
Mix together sweet corn kernels, creamed corn, corn muffin mix, eggs, sour cream and sugar in a bowl.
- Pour batter into large slow cooker. Spread out evenly so it cooks on outsides and center properly.
- Melt butter and pour over top.
- Cover and cook on high for 2-3 hours until center is set and firming up.
Use toothpick to ensure it comes out almost clean (it is supposed to be a soft kinda’ looser dish)
If you want to add cheese to top, do so 30 minutes before it is done so it can melt.

Is corn muffin and cornbread mix the same?
Most traditional corn muffins contain corn, cornmeal, water, butter, flour and sugar. Some people sweeten the corn muffins further with honey, yogurt and vanilla extract.
Cornbread muffins though are traditionally made with cornmeal, water, butter and flour.
- SO yes they are very similar, but have a few differences.
- If you cannot order or find Jiffy you could try whatever variety you can find. Just use about 9 oz. of it.
Does cornbread casserole need to be refrigerated?
Yes! If there are leftovers you should put them in an airtight storage container.
Alternatively you can put it on a bowl and cover with plastic wrap and refrigerate. Pint size freezer bags are another great storage option.
If you’re looking for a meatless side dish you can opt for this vegetarian Jiffy muffin mix. We have made this quickly to using our Instant Pot corn casserole recipe!

There are several variations of this east Crockpot corn casserole recipe, but I love this one. I’ve made it for years.
The only thing I’ve added differently this time were some chiles which added more flavor, not spice.
I use a can of mild diced chiles but you can choose the amount of heat. Medium would be great too.
Can you freeze corn casserole?
I honestly prefer to refrigerate what’s left and eat it the next 2 days or so. It reheats well in the microwave in about 30 seconds.
BUT if you have a bunch you can use freezer bags and store for longer periods of time in the freezer too. To reheat allow it to reach room temperature ideally, and then warm in microwave or oven.

Want to make another Crockpot side dish? We love slow cooker cabbage too.

I have doubled the recipe before and it worked super well! I usually stir it up after an hour or so, just as the edges get a little firm so that they don’t burn too bad with the slightly longer cook time. It doesn’t hurt the consistency of the dish at all in the end! I don’t usually use the extra sugar because the corn is already sweet, but I may have to try that now!
