Equipment

  • Oven
  • Mixing bowls
  • 9×13 Baking Dish
  • Spoon or Spatula

Ingredients
  

Cornbread Batter

  • 2 boxes Jiffy corn muffin mix (the blue box, not the honey one)
  • 2 eggs
  • 2/3 cup milk (any kind)

Filling and Cheese

  • 1 can black beans 15 oz, drained
  • 1 can corn 15 oz, drained
  • 1 can diced tomatoes 14.5 oz, drained well
  • 1 packet taco seasoning
  • 1/2 cup sour cream
  • 2 cups sharp cheddar cheese shredded
  • 1 cup Monterey Jack cheese shredded

Other

  • 2 tbsp olive oil for greasing pan

Instructions
 

  • Preheat oven to 400°F. Grease a 9x13-inch baking dish with olive oil or cooking spray.
  • In a mixing bowl, combine Jiffy corn muffin mix, eggs, and milk. Stir until batter is smooth.
  • Pour half the batter into the greased baking dish and spread evenly.
  • In a separate bowl, mix black beans, corn, diced tomatoes, taco seasoning, and sour cream to create the filling.
  • Spread the filling mixture evenly over the cornbread batter in the dish.
  • Top with shredded cheddar and Monterey Jack cheese.
  • Dollop and spread the remaining cornbread batter over the cheese layer. It’s okay if it doesn’t fully cover the cheese.
  • Bake for 18–20 minutes or until the top is golden brown and no longer jiggles in the center.
  • Let the casserole rest for 5 minutes before slicing and serving.

Notes

Use pre-shredded cheese for convenience. Swap Monterey Jack for more cheddar if needed. Greek yogurt works in place of sour cream. Taco seasoning can be replaced with a blend of chili powder, cumin, garlic powder, and paprika.
