- Ground beef: Provides hearty, savory protein that forms the base of the casserole’s robust flavor.
- Medium onion, diced: Adds a subtle sweetness and depth when sautéed with the beef.
- Taco seasoning packet: Infuses the beef mixture with aromatic Mexican spices for authentic taste.
- Can of diced tomatoes with green chilies, drained: Adds moisture and a gentle heat that brightens the dish.
- Can of corn, drained: Brings sweet bursts of texture that complement the spicy elements.
- Shredded cheddar cheese: Melts perfectly on top, creating a golden, gooey crust.

How to Make Mexican Cornbread Casserole Recipe
Step 1: Prepare the Baking Dish and Brown the Beef
First things first, preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking and help with even cooking. Then, brown the ground beef in a skillet over medium heat, mixing in the diced onion as it cooks. This step is essential—not only do you want the beef fully cooked, but browning it with the onions builds a deep savory flavor foundation for the casserole. Once cooked through, drain any excess fat to keep the dish from becoming greasy.
Step 2: Season and Combine the Beef Mixture
Stir the taco seasoning packet into the browned beef and onions, coating everything evenly with those beloved spices. Next, add the drained diced tomatoes with chilies and the corn to the skillet. Allow everything to cook together for about 5 minutes so the flavors meld nicely. This stage ensures that your filling is bursting with both a hint of sweetness and just the right amount of gentle heat.
Step 3: Prepare the Cornbread Batter with Sour Cream
While your beef mixture simmers, prepare the cornbread batter according to the directions on the box. Here’s a little secret that makes all the difference: stir in one cup of sour cream to the batter. This simple addition makes your cornbread batter extra moist and tender, providing a luscious contrast to the savory filling below once it bakes.
Step 4: Layer and Bake the Casserole
Now for the fun part: assembling the casserole! Spread the seasoned beef mixture evenly at the bottom of your greased baking dish. Next, pour the enriched cornbread batter on top, smoothing it out gently. Sprinkle the shredded cheddar cheese liberally over the batter to guarantee a beautifully golden, cheesy crust after baking. Bake the entire casserole for 30 to 35 minutes until the cornbread topping is golden brown and a toothpick inserted in the center comes out clean.
How to Serve Mexican Cornbread Casserole Recipe

Garnishes
To elevate your Mexican Cornbread Casserole Recipe, consider fresh garnishes like chopped cilantro, sliced green onions, or a dollop of guacamole or sour cream. These toppings add color, freshness, and an inviting creamy contrast that make every bite even more delightful.
Side Dishes
This casserole pairs wonderfully with crisp, refreshing side dishes such as a simple green salad, Mexican street corn, or zesty black bean salad. The crunchy textures and bright flavors of these sides beautifully offset the casserole’s warm, hearty richness.
Creative Ways to Present
For a festive dinner party or family gathering, serve your casserole in individual ramekins or cast-iron skillets to impress guests. You can also layer it in a large glass dish so everyone can admire the vibrant, cheesy topping through the sides before serving—pure comfort food with a welcoming look!
Make Ahead and Storage
Storing Leftovers
Leftover Mexican Cornbread Casserole Recipe keeps well in an airtight container in the refrigerator for up to 4 days. Just cover tightly to preserve moisture and prevent it from drying out, ensuring you can enjoy the warm flavors again later in the week.
Freezing
If you want to make this casserole ahead of time, it freezes beautifully. Assemble the casserole completely but do not bake. Wrap the dish tightly with plastic wrap and foil, and freeze it for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator before baking as directed.
Reheating
To reheat, pop a portion in the microwave or warm the whole casserole in a 350°F oven until heated through. Cover with foil while reheating to keep the bread moist and prevent the cheese from over-browning. A little extra sprinkle of fresh cheese before serving can revive that melty finish!
FAQs
Can I substitute ground turkey for the beef?
Absolutely! Ground turkey works well and creates a lighter version of the casserole while keeping all the wonderful flavors intact. Just be sure to season it thoroughly for maximum taste.
What if I don’t have a taco seasoning packet?
No worries! You can easily make your own with a mix of chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper. Adjust the amounts to suit your taste, and you have a fresh, customizable taco seasoning blend.
Is it possible to make this dish vegetarian?
Yes, simply swap the ground beef for a plant-based protein like seasoned black beans or lentils. This keeps the texture hearty while still letting the corn, cheese, and spices shine through beautifully.
Can I use homemade cornbread instead of mix?
Definitely! Using your own scratch cornbread recipe adds a lovely personal touch. Just fold the sour cream into your batter to maintain that moist, rich texture that pairs perfectly with the filling.
How spicy is this casserole?
The heat level is mild to moderate thanks to the taco seasoning and green chilies in the tomatoes. You can adjust the spice by choosing a mild or hot taco seasoning or adding extra chilies depending on your preference.

There is something truly special about the way this Mexican Cornbread Casserole Recipe brings comfort food and vibrant Mexican flavors together in one dish.
