Ingredients

Scale
  • 1 pound ground beef
  • 1 medium onion, chopped
  • 1 (15 ounce) can black beans, rinsed and drained
  • 1 (15 ounce) can whole kernel corn, drained
  • 1 (10 ounce) can Rotel diced tomatoes and green chilies, undrained
  • 1 teaspoon chili powder
  • 1/2 teaspoon cumin
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup shredded cheddar cheese, divided
  • 1 box (8.5 ounces) Jiffy Corn Muffin Mix
  • 1 large egg
  • 1/3 cup milk

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large skillet over medium heat, cook the ground beef and onion until the beef is browned and the onion is soft. Drain off any excess grease.
  3. Stir in the rinsed black beans, drained corn, Rotel tomatoes (with liquid), chili powder, cumin, salt, and pepper into the skillet with the beef mixture. Cook for 5 minutes, stirring occasionally.
  4. Remove the skillet from the heat. Stir in 1/2 cup of the shredded cheddar cheese into the beef mixture. Spread this mixture evenly into the prepared baking dish.
  5. In a medium bowl, prepare the Jiffy Corn Muffin Mix according to the package directions, using the egg and milk specified on the box. Do not overmix the batter.
  6. Pour the cornbread batter evenly over the top of the beef mixture in the baking dish.
  7. Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the cornbread batter.
  8. Bake for 25 to 30 minutes, or until the cornbread topping is golden brown and a toothpick inserted into the center comes out clean.
  9. Let the Cowboy Cornbread Casserole rest for 5 minutes before slicing and serving.

Notes

  • For extra flavor in the beef layer, add 1 packet of taco seasoning along with the chili powder and cumin.
  • If you prefer a slightly sweeter cornbread topping, use a sweet style Jiffy mix if available.
  • This hearty ground beef casserole freezes well after baking; cool completely, wrap tightly, and freeze for up to three months. Reheat covered at 350 degrees until heated through.
