Make this hearty Mexican Cornbread Casserole for a satisfying one-dish dinner. This recipe layers seasoned ground beef and vegetables beneath a simple, cheesy cornbread topping.

Ingredients

Scale
  • 1 pound ground beef
  • 1 small onion, diced
  • 1 packet taco seasoning
  • 1 can (10 ounces) diced tomatoes with green chiles, drained
  • 1 cup corn kernels, drained (canned or frozen)
  • 1 cup shredded cheddar or Mexican-blend cheese
  • 1 box cornbread mix (such as Jiffy)
  • 1 large egg
  • 1/3 cup milk
  • 2 tablespoons unsalted butter, melted

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease an 8×8 or 9×9-inch baking dish.
  2. Place a skillet over medium heat. Brown the ground beef with the diced onion until the beef is fully cooked. Drain any excess grease from the skillet.
  3. Stir the taco seasoning, drained diced tomatoes with chiles, and corn into the cooked beef mixture. Simmer this filling for 2 to 3 minutes.
  4. Spread the beef mixture evenly into the bottom of your prepared baking dish. Sprinkle the 1 cup of shredded cheese over the beef layer.
  5. In a separate bowl, mix the cornbread mix, egg, milk, and melted butter until the batter is just combined. Do not overmix.
  6. Gently spread the cornbread batter over the cheese and beef layer in the baking dish.
  7. Bake uncovered for 35 to 40 minutes, or until the cornbread topping is golden brown and set when lightly touched.
  8. Let the casserole rest for 5 to 10 minutes before you cut and serve it.

Notes

  • For extra creaminess in the filling, stir in 1/2 cup of sour cream with the beef mixture before topping with cornbread batter.
  • Add 1/2 cup of sliced jalapeños or pickled jalapeños to the beef mixture for more heat.
  • Garnish the finished casserole with chopped fresh cilantro or green onions before serving.
