Description

A quick and flavorful Mexican casserole layered with seasoned beef, beans, corn, tortillas, and cheese. Perfect for busy weeknights and make-ahead meals.


Ingredients

  • 1 pound ground beef
  • 1 small onion, chopped
  • 1 packet taco seasoning (1 ounce)
  • 1/2 cup water
  • 1 (15-ounce) can black beans, drained and rinsed
  • 1 (15-ounce) can corn, drained
  • 1 (10-ounce) can diced tomatoes with green chilies (such as Rotel), undrained
  • 2 cups shredded cheddar cheese
  • 6 small flour tortillas (or corn, if preferred)
  • Cooking spray or oil for greasing the baking dish
  • Optional toppings: sour cream, chopped cilantro, diced avocado, sliced jalapeños

Instructions

  1. Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  2. In a large skillet over medium heat, cook the ground beef and chopped onion until beef is browned and onions are soft, about 6–8 minutes.
  3. Drain any excess grease, then stir in the taco seasoning and water. Let it simmer for 2–3 minutes until thickened.
  4. Mix in the black beans, corn, and diced tomatoes with green chilies. Cook for another 2 minutes to heat through.
  5. Place two tortillas on the bottom of the baking dish, tearing as needed to cover the base.
  6. Spoon a third of the meat mixture over the tortillas and sprinkle with a third of the cheese.
  7. Repeat layers twice more—tortillas, meat, cheese—ending with cheese on top.
  8. Cover loosely with foil and bake for 20 minutes. Uncover and bake an additional 10 minutes until cheese is bubbly and slightly golden.
  9. Let the casserole rest for 5–10 minutes before slicing and serving with your favorite toppings.

Notes

  • Swap ground beef for turkey or shredded chicken for a lighter version.
  • Make it vegetarian by omitting meat and doubling the beans.
  • Add cooked rice or quinoa to make it more filling.
  • Use a Mexican cheese blend or pepper jack for added spice.
  • Add enchilada sauce between layers for a saucier casserole.
