Taco Corn Casserole Recipe

One of our favorite family recipes is corn casserole, so the past few months I’ve spent some time developing some alternative ways to enjoy the classic 5 ingredient corn casserole. Think not just side dish…but main dish recipes, meat included. Because we love Mexican flavored food, this taco corn casserole was born.

Leftover Taco Meat

Do you ever have leftover taco meat in the fridge? Honestly, we rarely do. The kids DEVOUR tacos, so if we do have a little bit of taco beef leftover, it won’t last more than a day. If you’re lucky enough to have leftovers, that makes this recipe extra easy. Just use about a pound of taco meat (maybe 1 ½ cups?).

If you tend to not have any leftovers, cook one pound of ground beef and then season it with about 3 tablespoons of taco seasoning to prepare this recipe. 

How to Make Taco Casserole

This recipe is literally dump, mix and put in a pan to bake.

  • Be sure to drain the can of whole kernel corn (not the creamed corn) and the green chilies.
  • Use jalapeno peppers instead of or in addition to the green chiles if you’re looking for spice.
  • We like to use cheddar cheese, but you can use a Mexican cheese blend if you’d like.
  • This casserole will take about 60-70 minutes to bake if using a square 9×9 baking dish or 45-50 minutes in a 9×13 baking pan. It should be slightly puffy and totally set in the center.

Can I make taco casserole ahead of time?

Yes! You can mix the ingredients for this casserole together, spread it in the baking pan, then cover and refrigerate until you want to bake it. Remove the casserole from the refrigerator 30 minutes before baking so the chill comes off.

Can I make taco casserole in the 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.

What to Serve on Taco Casserole

This taco casserole has a very simple flavor. We like to pile it high with fresh pico de gallo…or you can use your favorite salsa recipe. Top it off with a dollop of sour cream.

What to Serve with Taco Casserole

We like to serve a simple side salad with this casserole. You could also serve green beans, tortilla chips or refried beans.

  • 1 pound taco seasoned ground beef (either leftover meat or beef cooked specifically for this purpose)
  • 8 ounces Jiffy Corn Muffin mix (1 box)
  • 15 ounces whole kernel corn (drained)
  • 15 ounces creamed corn (not drained)
  • 1 cup sour cream
  • 1/2 cup melted butter
  • 1 cup shredded cheddar cheese
  • 1/4 cup diced green chilies (drained)



  • Preheat the oven to 350 degrees.
  • In a bowl, mix all of the ingredients together and pour into a greased 9×9" or 9×13" baking pan. (NOTE: Ours fit in an 9" baking pan with deep sides. This casserole WILL expand slightly while baking so if you are afraid of it spilling over or want it to bake more quickly, use a 9×13 baking pan. Baking time will change if you use a different pan.) 
  • This casserole will take about 60-70 minutes to bake if using a square 9×9 baking dish or 45-50 minutes in a 9×13 baking pan. Bake until lightly browned and set in the center. (The exact time will depend on the pan you use so watch it closely. The center should not be jiggly. If it is a deep casserole it will take longer to bake.)
  • Serve immediately with fresh salsa and a dollop of sour cream.



**The time needed to cook this casserole may vary slightly depending on the pan you use. Most times it takes us a full hour to cook it. Plan for up to 70 minutes of baking, but check it several times.
The calories shown are based on the recipe serving 8 people, with 1 serving being ⅛ of the casserole.

Found this to be exceptionally greasy. It could have been due to the olive oil spray we used on the pan. Next time I’d use half the butter and half the sour cream.

I made this a couple years ago and thought it was amazing!! Did it again tonight but instead I split the mixture into two 7×11 pans and baked for 45 mins and it came out near perfect!! Could have used maybe 5 less minutes in the oven. Do you think it could be frozen after baking?

Can I prepare this the night before and cook it the next morning…will it need to cook longer since it will be cold? I have made this in the past and we love it!

I wanted to double this recipe. What size pan should I use and any ideas how much longer it would take to cook?

Seemed undercooked with the temp given, but I’m not sure how cooked it was supposed to be anyway.. 🤷🏼‍♀️ If you prefer, you can always add chips like the hubby! All that matters is that (1) the photos of this dish do NOT do it justice! And I say that because (2), in fact, this dinner is absolutely great! Definitely recommend trying!!

It didn’t turn out very well for me.. I put in more chilies than the recipe called for, but made everything like it said. We didn’t really taste them sadly. The cornbread didn’t cook all the way thru. Baked it for over 70minutes in the 9×13 casserole dish. I do want to know with the taco meat do you make it with water and the taco seasoning? I didn’t use the water.

Can you use two cans of regular corn drained (I don’t have cream style on hand) ?

Can you use leftover cornbread instead of the jiffy mix?

Definitely needs a 9×13!!!

Could salsa be used instead of the green chilies or could they be omitted altogether?

Do I mix the jiffy corn mix by package directions before mixing it with all the other ingredients?
