Preheat the Air Fryer to 400°F (200°C).

In a skillet over medium heat, brown the ground beef with diced onions and bell peppers until cooked through. Drain excess fat.

In a large bowl, combine the cooked meat, black beans, corn, diced potatoes, taco seasoning, and salt and pepper. Stir until well mixed.

Pour the mixture into the air fryer basket and spread it evenly.

Air fry at 400°F (200°C) for 15-20 minutes, shaking the basket halfway through for even cooking.

Sprinkle the shredded cheese on top and return to the air fryer for an additional 3-5 minutes until the cheese is melted and bubbly.

Let the casserole cool for a few minutes, then serve hot and enjoy!
