What Kind of Cornbread Mix Should I Use?

You can go with any boxed cornbread mix you like, but I usually reach for Jiffy—it has the perfect balance of sweetness and texture for this casserole. If you’re more into savory flavors, you can choose a stone-ground or Southern-style mix that’s a little less sweet. You can also make your own cornbread batter from scratch if you prefer a homemade touch. Either way, the key is making sure the batter is thick enough to hold its shape on top of the meat layer but not too dense that it dries out during baking.

Options for Substitutions

The beauty of Mexican Cornbread Casserole is how flexible it is. Don’t have everything on hand? No problem. Here are some easy swaps:

• Ground Beef: Swap it out for ground turkey or even shredded rotisserie chicken for a leaner version.
• Cheese: Use Monterey Jack, pepper jack, or a Mexican blend if you want more flavor depth.
• Corn: Frozen or canned both work well—just drain it first if using canned.
• Toppings: Not into jalapeños? Try sliced olives or green onions instead.
• Sour Cream: Plain Greek yogurt works great if you want a lighter topping.
• Beans: Add a layer of black beans or refried beans for extra heartiness.
• Spices: Add taco seasoning or your own blend of cumin, chili powder, and paprika for added depth.

Feel free to make it your own!

Ingredients for This Mexican Cornbread Casserole

• Ground Beef
  This is the savory base of the casserole. I use 80/20 ground beef for the best flavor and juiciness, but you can go leaner if you prefer.
• Onion
  A small chopped onion adds sweetness and aroma as it cooks with the beef, bringing a deeper flavor to the meat layer.
• Taco Seasoning
  This gives the beef that signature Tex-Mex kick. You can use a packet or make your own with chili powder, cumin, garlic powder, and paprika.
• Canned Corn
  Sweet corn adds a burst of texture and sweetness that balances the spice and saltiness of the beef and cheese.
• Diced Tomatoes (or Rotel)
  These bring acidity and moisture to the filling. If you want a little heat, go with Rotel.
• Cheddar Cheese
  Melty, golden, and essential. It binds the top layer and gives every bite that rich, cheesy pull.
• Cornbread Mix
  The fluffy top layer that makes this a true casserole. It’s the perfect contrast to the spicy meat filling below.
• Milk & Eggs
  These bind the cornbread mix into a smooth batter that bakes up tender and moist.
• Sour Cream
  Cool, tangy, and perfect for topping. It adds a creamy finish to each bite.
• Fresh Cilantro & Jalapeños (optional)
  For garnish and an extra pop of flavor and color.

Step 1: Brown the Beef

Start by cooking your ground beef in a skillet over medium heat. Break it apart with a wooden spoon as it cooks. Once it’s nearly browned, add in the chopped onion and let it sauté with the meat until soft and translucent.

---

Step 2: Add Seasoning and Mix-ins

Drain any excess fat from the beef, then stir in the taco seasoning. Add the canned corn and diced tomatoes (drained if using canned). Let everything simmer for a few minutes so the flavors meld together.

---

Step 3: Prepare the Cornbread Batter

While the beef mixture simmers, mix the cornbread batter according to the package instructions—usually with milk and eggs. You want a pourable consistency, but not too thin.

---

Step 4: Layer the Casserole

Pour the meat mixture into a greased baking dish or cast iron skillet. Spread it out evenly. Then carefully pour or spoon the cornbread batter on top, smoothing it gently so it covers the beef layer completely.

---

Step 5: Add Cheese and Bake

Sprinkle shredded cheddar cheese over the top of the cornbread batter. Pop the dish into a preheated oven and bake until the cornbread is golden and cooked through, usually around 25–30 minutes.

---

Step 6: Garnish and Serve

Let the casserole cool slightly. Then top with sour cream, fresh cilantro, diced tomatoes, and sliced jalapeños if desired. Slice and serve warm!

How Long to Cook the Mexican Cornbread Casserole

You’ll want to bake this casserole at 375°F (190°C) for about 25 to 30 minutes. Keep an eye on the top—the cornbread should be golden brown, and a toothpick inserted in the center should come out clean. If you’re using a deeper dish or doubling the recipe, it may need an extra 5–10 minutes. Let it rest for 5 minutes before slicing so everything sets nicely.

Tips for Perfect Mexican Cornbread Casserole

• Drain the beef well after browning to avoid a soggy bottom layer.
• Don’t overmix the cornbread batter—just stir until combined to keep it light and fluffy.
• Spread the batter gently over the meat layer to keep the layers distinct.
• Add cheese halfway through baking if you prefer a gooey top with less browning.
• Use a cast iron skillet for even heat and a crispier crust.
• Customize the spice level with mild or hot diced tomatoes and jalapeños.
• Let it rest before serving so the layers settle and slice more cleanly.
• Double it up for a crowd—just increase baking time and use a larger dish.

Watch Out for These Mistakes While Cooking

• Using too much liquid in the meat layer – If your tomato or corn mix is too watery, the cornbread can turn soggy. Drain canned ingredients well.
• Pouring hot filling over cold cornbread batter – Always layer the batter on top of the filling, not the other way around, or the texture will be off.
• Skipping the cheese topping – It’s not just for flavor; it also helps keep the cornbread from drying out during baking.
• Overbaking – The cornbread can become dry quickly, so start checking at the 25-minute mark.
• Not seasoning the meat enough – Bland meat makes the whole dish fall flat. Be generous with your taco seasoning.
• Using too small a baking dish – If your dish is too small, it might overflow. Aim for a deep 9×13-inch pan or large skillet.
• Not letting it rest – Cutting into it too soon can make the layers collapse. Give it at least 5 minutes to firm up.
• Using too much batter – If you overload the top with thick cornbread, it may not bake through evenly. Stick to the mix’s recommended amounts.
