How to Make Mexican Cornbread Casserole
Step 1: Preheat and Prepare Your Baking Dish
Start by preheating your oven to 375°F (190°C), ensuring a toasty, even bake for your casserole. Lightly grease a 9×13-inch baking dish with your favorite cooking spray or a little butter. This not only prevents sticking, but also keeps clean-up blissfully easy—always a win!
Step 2: Sauté the Beef and Onions
In a large skillet set over medium heat, add the ground beef and chopped onion. Cook them together, breaking up the meat with a spatula until the beef is deeply browned and the onions turn soft and fragrant. If there’s any extra fat, just drain it off so the finished dish isn’t greasy.
Step 3: Add Corn, Rotel, Beans, and Seasoning
Now, it’s time for all those Tex-Mex flavors to mingle. Stir the canned corn, Rotel tomatoes with green chilies, black beans, and taco seasoning into your browned beef mixture. Let it all simmer for about five minutes to concentrate the flavors. As the aroma fills your kitchen, try not to sneak too many tastes!
Step 4: Stir in the Cheese
Remove the skillet from the heat and mix in 1 cup of shredded cheddar cheese. The cheese will melt into the warm filling, creating luscious threads throughout the savory mix. This step is where the magic happens—it holds all the ingredients together! Spread this meaty mixture evenly in your prepared baking dish.
Step 5: Mix the Cornbread Batter
In a large mixing bowl, combine the Jiffy corn muffin mix, egg, milk, and sour cream. Stir until the batter is just smooth—don’t overmix! This soft, creamy batter will bake into a perfectly golden, pillowy top crust that complements the hearty base underneath.
Step 6: Assemble and Bake the Casserole
Pour the cornbread batter over your beef mixture, smoothing it gently with a spatula so it evenly covers the surface. Pop the casserole into the preheated oven and bake for 25–30 minutes, until the cornbread is golden and set. For irresistible gooeyness, sprinkle extra cheddar cheese on top during the last five minutes of baking, then slide it back in until melted.
Step 7: Rest, Slice, and Serve
Once baked, let the Mexican Cornbread Casserole rest for about five minutes. This makes slicing easier and gives the flavors a chance to settle. Serve it up warm and watch everyone rush to the table!
How to Serve Mexican Cornbread Casserole

Garnishes
The right toppings can make your Mexican Cornbread Casserole feel truly restaurant-worthy! Classic garnishes include a dollop of creamy sour cream, a generous sprinkle of chopped fresh cilantro, or some sliced green onions. Sliced jalapeños or a dash of hot sauce are perfect for those who love a little extra heat.
Side Dishes
This casserole is filling all on its own, but pairing it with sides makes dinner feel like a fiesta. A crisp green salad with lime vinaigrette, smoky roasted veggies, or a scoop of tangy black bean salsa are all fabulous partners. Even some classic Mexican rice rounds out the meal beautifully.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftovers of Mexican Cornbread Casserole hold up beautifully! Cool the casserole to room temperature, then cover the dish or transfer portions to airtight containers. Store in the fridge for up to 4 days. The flavors somehow get even bolder overnight, making next-day lunches a true treat.
Freezing
Planning ahead? You can absolutely freeze this casserole! For best results, slice it into portions and wrap each in foil before placing in a freezer-safe bag or container. It’ll stay delicious for up to 2 months—just thaw overnight in the fridge before reheating.
Reheating
To reheat, you can pop slices in the microwave for a quick fix, or cover the dish with foil and warm it in a 350°F oven for about 15–20 minutes. If the cornbread seems a bit dry, just add a splash of broth or a sprinkle of cheese on top before reheating for extra moisture and flavor.
FAQs
Can I make Mexican Cornbread Casserole vegetarian?
Definitely! Swap the ground beef for plant-based meat, cooked lentils, or even extra black beans and corn. The seasoning and flavorful cornbread topping mean you won’t miss the meat one bit.
What can I use instead of Jiffy corn muffin mix?
If you can’t find Jiffy or want to go from scratch, mix together 1 cup cornmeal, 1/4 cup flour, 2 tablespoons sugar, 1 teaspoon baking powder, and a pinch of salt. Add the egg, milk, and sour cream as directed and proceed with the recipe.
Can I add more veggies to the casserole?
Absolutely! Bell peppers, diced zucchini, or even spinach would mix in well with the ground beef layer. Sauté them with the onions for best results.
Is it spicy?
Not particularly—it has gentle heat from the Rotel tomatoes with green chilies, but you can choose mild or hot based on your preference. For an extra kick, add sliced jalapeños or more taco seasoning.
Can I double the recipe for a crowd?
Mexican Cornbread Casserole scales up like a dream! Double the ingredients for a larger pan (or two 9×13-inch pans) and you’ve got a guaranteed crowd-pleaser. Just add a few more minutes to the baking time if the casserole is deep.
