Ingredients

  • Vegetable Oil: 2 tablespoons
  • Chicken Breast: ¾ pound skinless, boneless, cubed
  • Taco Seasoning Mix: ½ 1.25-ounce package
  • Black Beans: 1 15-ounce can, rinsed and drained
  • Sweet Corn: 1 8.75-ounce can, drained
  • Salsa: ¼ cup
  • Water: As needed to prevent dryness
  • Mexican-Style Cheese: 1 cup shredded
  • Tortilla Chips: 1 ½ cups crushed

Instructions
 

Preheat Oven:

  1. Preheat the oven to 350°F (175°C). Prepare a 9x13-inch baking dish by lightly greasing it.

Cook the Chicken:

  1. Heat the vegetable oil in a large skillet over medium-high heat. Add the cubed chicken and sauté until thoroughly cooked and no longer pink inside, approximately 6 to 8 minutes. Ensure even cooking by stirring occasionally.

Incorporate Seasoning and Vegetables:

  1. Add the taco seasoning mix, black beans, corn, salsa, and a small amount of water to the skillet. Stir thoroughly to combine all ingredients. Reduce the heat to medium-low, cover, and simmer for 10 minutes to allow the flavors to meld.

Transfer to Baking Dish:

  1. Transfer the cooked chicken mixture into the prepared 9x13-inch baking dish. Spread evenly to ensure even baking.

Add Cheese and Tortilla Chips:

  1. Sprinkle ½ cup of the shredded Mexican-style cheese over the casserole. Add the crushed tortilla chips in an even layer on top.

Bake the Casserole:

  1. Place the baking dish in the preheated oven and bake for 15 minutes.

Add Remaining Cheese:

  1. After 15 minutes, sprinkle the remaining ½ cup of cheese over the top. Continue baking until the cheese is fully melted and bubbly, approximately 5 additional minutes.

Cool and Serve:

  1. Allow the casserole to cool for several minutes before serving. Serve warm and garnish with desired toppings such as sour cream, avocado, or jalapeños.
