Mexican Corn Casserole

by Alli

If you’re tired of the same old boring side dishes or need an easy, delicious casserole for a potluck or family get-together, my Mexican Corn Casserole fits the bill. It’s comfort food to the max!

Every single time I serve this casserole, there are zero leftovers. None. Ever. And it makes 12-15 servings.

The smell of this creamy, corn infused casserole wafting through the house just screams deliciousness! It’s a spoon bread on steroids, in a good way.

My recipe calls for regular cornmeal and baking soda because I’m well aware that self-rising cornmeal is not available in some areas.

Since I live in the south and self-rising cornmeal is always available, I use self-rising cornmeal mix and omit the baking soda.

This casserole is the perfect side dish. I’ve been known to eat it as a main dish as well.

For this recipe, you will need the following ingredients:

  • Eggs
  • Whole kernel corn, drained
  • Cream-style corn
  • Cornmeal
  • Buttermilk
  • Butter 
  • Green chilies
  • Chopped onion
  • Baking soda
  • Cheddar cheese

Why use Buttermilk?

Usually, buttermilk is used in recipes not just because it has a more complex flavor than regular milk, and because it’s more acidic than milk.

The acidity allows buttermilk to react with ingredients such as baking soda or baking powder to produce carbon dioxide bubbles. That means light, tender and delicious.

What Can I Substitute for Buttermilk?

If you don’t have any buttermilk on hand, you can easily create a substitute by pouring 1 tablespoon of lemon juice into a liquid measuring cup. Add milk to reach the 1 cup mark. Allow the mixture to sit at room temperature for 5-10 minutes.

No lemon juice? Use white vinegar instead and follow the same directions.  You can also use sour cream or plain yogurt mixed with 2 Tablespoons of milk or enough to create the consistency of buttermilk.

Mexican Corn Casserole is my favorite fall/winter comfort food.  What’s yours?

This looks great. I also want to try your leftover turkey ring, too. Great recipes. I love your helpful hints part, too.

Alli December 3, 2014 - 9:41 am

I ended up making a turkey ring and a ham ring this past weekend. My grown sons were here and they scarfed them right down.

Shirley Wood December 3, 2014 - 7:10 am

Sounds and looks delicious! It is a busy time so easy recipes are much appreciated. I think my husband and I would both enjoy this. I’m so thankful my husband enjoys casseroles!
Our favorite winter comfort food is my Meat & Potato Casserole.

It’s probably my family’s very favorite side dish. It’s so good on a cold winter night.

Michelle December 3, 2014 - 10:02 am

LOVE the idea of cheese, it just takes it up another notch! We’ve done the chiles but not the cheese!

Alli December 4, 2014 - 7:24 am

Cheese makes everything better! 🙂

I’ve never had a MEXICAN Corn Casserole – interesting! I make a regular one, normally right at this time of the year for one of our big family parties! I wonder if they would balk at me getting out of the box a bit with this one?

Alli December 4, 2014 - 7:20 am

I like that it’s spicy, but not too spicy, not even for the kids.

Kristen from The Road to Domestication December 10, 2014 - 3:24 pm

Awesome! Thanks so much for linking up to the #homematters linky party! We hope to see you again this coming Friday!

Yummy! I love corn casseroles but have never had a mexican corn casserole! I’ve printed this recipe off and plan on trying it here soon! Thanks for the share!!!

Reginia Cordell December 3, 2014 - 12:09 pm

Of course you had me at Mexican but now you’ve put Mexican and casserole in the same recipe. It sounds like a comfort food delight. Now, should I put it with a beef dish or fried chicken?

Alli December 4, 2014 - 7:19 am

Both! 🙂

Megan L. December 3, 2014 - 3:44 pm

This looks delicious and is definitely different to anything I’ve ever had before. Will have to whip this up for me and the husband one night! Fab recipe!

Sarah Sofia Knepp December 3, 2014 - 4:28 pm

Zan December 3, 2014 - 5:42 pm

This looks delicious, Alli. I love all things corn and I am sure this would make a great addition to my Hispanic dinners!!

Just made this. Not a big fan. It has too much onion flavor and needs a little sugar. I am used to the sweeter version you find in restaurants.

Alli March 7, 2020 - 7:38 pm

Thanks for the comment. Nope, no sugar in this recipe. I don’t like it sweet. Have a blessed evening.
