Step-by-Step Instructions

1. Preheat and Prep

  2. Add the diced onion and minced garlic to the skillet and cook for 2–3 minutes, until softened.
  3. Stir in the taco seasoning, black beans, corn, diced tomatoes with green chilies, and optional jalapeños. Cook for 5 minutes, stirring occasionally, to let the flavors meld.

3. Assemble the Casserole

  1. Transfer the beef mixture to the prepared baking dish, spreading it out evenly.
  2. Sprinkle 1 cup of shredded cheese over the top of the beef mixture.

4. Add the Topping

  1. Sprinkle the crushed tortilla chips evenly over the cheese layer.
  2. Top with an additional 1/2 cup of shredded cheese for extra gooeyness.
