This Easy Tex Mex Casserole recipe has turned into a favorite meal at our house! Flavorful ground beef topped with cornbread makes an easy casserole even the kids will love! It’s a tasty ground beef casserole topped with a sweet cornbread and packed with veggies and salsa-y goodness. 

The best thing about casseroles — and this tex mex casserole is no exception — is how versatile and adaptable they are. If you’re missing an ingredient, chances are you have something else that will substitute just fine!

Want to add extra protein to your meal? Add some beans. Want more spice? Throw in a can of diced green chiles or a chopped jalapeno! Need it more mild? Use tomato sauce instead of salsa.

Don’t have cornbread mix? Make your own (we recommend this Homemade Cornbread recipe)! 

Casseroles mean endless possibilities, combinations, and substitutions. So don’t be afraid to try this recipe! Whether you follow my instructions or tweak it and make it your own, I’m sure you and your family will love it!

What makes a casserole a casserole? 

Casseroles are made throughout the world and have existed in some form for millennia; though the casserole as we know it is more recently traced to the late 1800’s. 

A casserole typically contains a protein, vegetables, and a binding sauce or starch. Many tend to have cheese as well. There’s a lot of wiggle room within these parameters to make any number of unique casseroles.

What do you need to make Tex Mex Casserole?

To make this tasty ground beef cornbread casserole, you’ll need the following ingredients: 

  • Ground beef – this is the protein in your casserole. If ground beef isn’t your thing, you can substitute another protein. Black beans for a vegetarian or vegan variation, rotisserie chicken, leftover turkey meat, or pork are all great options! 
  • Onion – diced onion adds nutrition and flavor to your recipe. 
  • Green bell pepper – another vegetable component in your casserole. For more spice, you can substitute poblanos or jalapenos. Any color of bell pepper will also work great! 
  • Cumin – something I learned recently — make sure you have a decent cumin, or it can make your flavors wonky! McCormick has you covered. The $1 Great Value cumin … not so much. 
  • Salsa – you can use whatever you prefer! This is the binding sauce in the casserole recipe. Use green, red, hot, mild — make it your own! (I used a corn and black bean salsa – hence the black beans in the photos).
  • Canned corn you can also use frozen! 
  • Cornbread mix – Jiffy works, but I find that Famous Daves brand is our favorite store bought corn bread.  If you want to make your own cornbread, our homemade version is great!

How do you make Tex Mex Casserole? 

This hamburger cornbread casserole is so easy to make! That’s the nature of casseroles, right? Simplicity, great flavor, and tastes like home. 

To make this easy Tex Mex Casserole recipe you’ll need to follow 4 simple steps.

  1.  Cook your beef and vegetables 
  2. Whip up your cornbread
  3. Assemble.  Meat on the bottom of your dish and cornbread poured over the top!
  4. Bake!  Once baked, simply serve and enjoy!

What goes with Tex Mex Casserole?

One of the many great things about casseroles is they’re pretty much an entire meal in one dish. In this Tex Mex Casserole recipe, you have your protein, vegetables, and grains all covered! But if you want to add more variety to your meal, I recommend the following recipes and ideas:

Can I make Tex Mex Casserole ahead of time? 

Yes, you can make Tex Mex Casserole ahead of time! Simply prepare as directed and refrigerate for up to 12 hours if you’re planning to cook it later that day. 

Another option is to prepare the ground beef filling FAR ahead of time. You can freeze the filling for up to 3 months in a zipper freezer bag or other airtight container. DO NOT prepare and freeze the cornbread mix. 

When you’re ready to prepare your Tex Mex casserole, thaw the ground beef mixture in the fridge for 12-24 hours. If you forget to pull it out of the freezer (it happens to all of us!), run the bag under warm water until you can loosen the contents enough to remove.  

Place the filling in a 9×9 casserole dish. NOW you can prepare the cornbread mix. Top the thawed ground beef mixture with your prepared cornbread mix and cook for 20-25 minutes in the preheated oven. If your mixture is still a little frozen, you’ll probably need the full 25 minutes or perhaps even a little longer. After 25 minutes, keep an eye on the casserole so you don’t overcook the cornbread.

I recently tried this recipe with a few minor tweaks and its now on the keeper list with my kids and husband. I added some sour cream and shredded cheddar to the casserole. Then instead of cornbread I used 6 biscuits left from breakfast cut in half. I tucked them into the casserole with about 10 minutes left on the baking time and it was so good.

This came out delicious! Thank you. I did not have a bell pepper, so I subbed in a can of hatch green chilies and the flavor was still wonderful. I'm actually thinking of using the recipe as a meal prep for my lunches. It's healthy and low calorie and yummy!

I made this again last night but changed it up by using ground chuck instead of lean ground, and added fresh salsa (instead of regular bottled variety), made my favorite cornbread recipe (we don't get box mixes in Canada anyway) and swap out cumin and salt for taco seasoning. Amazingly awesome. Husband said he was only taking 1 serving but went back for more because 'it is too da#n good '. Thanks for sharing!

Loved this! I added jalapeño juice minced garlic, chili powder and a little more cumin (great value 😂). I used green onion instead because that’s all I had. I also added pinto beans and used rotel for my salsa. Thank you for this recipe. It was fun to play around with and so tasty!
