Tips for the Best Results
- Drain the beef: After browning, drain excess grease to keep the casserole from becoming oily.
- Season well: Taste and adjust spices — bold seasoning makes the dish sing.
- Add vegetables: Bell peppers, onions, or jalapeños can be sautéed with the beef for more texture and flavor.
- Mix cornbread lightly: Stir just until combined so the cornbread stays tender and fluffy.
- Let it rest: Allow the casserole to cool a few minutes before serving so it slices cleanly and flavors meld.
- Toppings: Serve with sour cream, fresh pico de gallo, avocado slices, cilantro, or extra salsa.
How to Make Easy Mexican Cornbread Casserole

- Preheat: Heat oven to 400°F. Spray a 9×13 baking dish with nonstick spray.
- Brown the beef: Cook ground beef in a skillet until no pink remains; drain off excess fat.
- Add the base: Stir in the cream of mushroom soup, undrained corn, and undrained Rotel. Add taco seasoning, salt, pepper, and onion powder. Stir to combine.
- Simmer briefly: Bring the mixture to a boil and let it cook about 5 minutes to meld flavors.
- Cheese: Remove from heat and stir in 2 cups of the shredded Mexican cheese. Spread the beef mixture evenly into the prepared baking dish.
- Cornbread topping: In a bowl, whisk the cornbread mix, eggs, and milk until just combined. Spread the batter evenly over the beef mixture.
- Bake: Bake 15–20 minutes, or until the cornbread is lightly browned and set.
- Finish: Remove from oven, sprinkle remaining 1 cup of cheese over the top, and return to oven 2–4 minutes until the cheese melts.
- Serve: Let rest a few minutes, then serve with sour cream, pico de gallo, and avocado slices if desired.
