Jalapeno Cheddar Corn Casserole

I had been dreaming up different ways I could change up our most-loved corn casserole recipe. It’s so delicious on it’s own, but there are countless tweaks you could make to this easy side dish…and Jalapeno Cheddar Corn Casserole had to be the first!

Fresh Jalapenos vs Canned Jalapenos

We added 2 freshly diced jalapenos to this casserole. If you’d like, you can use a 4 ounce can of diced jalapenos. Just be sure to drain it first! There’s really not much difference. The fresh jalapenos will not be 100% soft after baking in this casserole, so if you’d like them to blend in a little better, use canned. With canned you can control the heat a little more easily too.

Remember that if you use fresh, most of the heat is in the seeds and membrane, so remove those if you don’t want it too spicy.

How do you make corn casserole?

Corn casserole is one of the easiest side dishes to make. This version is just 7 ingredients

  • Jiffy cornbread mix
  • 1 can creamed corn
  • 1 can whole corn (drained)
  • 1 cup of sour cream
  • 1 stick of melted butter
  • 1 cup of cheddar cheese
  • Jalapenos

Mix this all up, put it in a greased pan and bake it in a preheated oven for about 45 minutes. That’s it! So, so easy.

Can I make corn casserole ahead of time?

If you’d like, you can mix up the corn casserole in advance and put it in the prepared pan. Cover the casserole and refrigerate it. Remove the dish from the fridge for about 30 minutes before you bake it. Then, bake as the recipe states.

Can I cook this corn casserole in a slow cooker?

Yes! Simply spray the liner of the slow cooker with cooking spray, then add the corn mixture to the slow cooker. Set on low and bake until the center is set. It should take about 4-6 hours.

I want to make this cornbread for Thanksgiving but would like to make mini muffins instead of in a casserole dish or cast iron skillet. Can this be done and if so, how long would it take to bake it?

Can I mix this up the day before & bake it off Thanksgiving Day? Also, do you add the egg & milk with the jiffy mix?

Can I cook this in a crockpot on low? I was thinking that I could cook it on low for like 10 hours or something but wasn’t sure if maybe High for shorter was the way to go? Thanks!

Can you prepare this the night before & bake in the morning?

Do you use the egg and milk that the jiffy box asked for. Or just the box of jiffy itself?

I made this and was excellent! Doubled the recipe, but when I didn’t have enough sour cream I improvised by adding cream cheese whisked with juice of japapeno peppers. Was fantastic!

I double this recipe and omit the jalapeño peppers for the most asked for side dish ever! It’s now included on Thanksgiving, Christmas and Easter dinner! ❤️👍🏻
