In a large mixing bowl, stir together black beans, cream of chicken soup, fire-roasted tomatoes, green chiles, cumin, and chicken.
Choose a deep-dish casserole dish that fits in your air fryer. Spray with non-stick cooking spray.
Layer ½ of the tortilla pieces in the bottom of the casserole dish.
Top the tortilla layer with half of the bean and chicken mixture. Sprinkle 1 cup of cheese over the chicken mixture. Layer with the other half of the tortilla pieces, then the remaining bean and chicken mixture.
Bake, covered with aluminum foil, at 350°F in the air fryer until hot and bubbly all the way through (about 45 minutes.)
Remove the aluminum foil and top with remaining cheese and crushed tortilla chips or corn tortilla pieces.
Place the dish back into the air fryer and continue cooking until cheese is melted and chips are becoming a bit golden.
Top with diced tomatoes, chopped cilantro, and some sour cream if desired
Plate, serve, and enjoy!
