In a large mixing bowl, combine the ground beef, breadcrumbs, onions, bell peppers, corn, black beans, egg, ketchup, tomato paste, and all the seasonings. Mix until just combined; avoid over mixing for a tender texture.
Form the mixture into a loaf shape that fits comfortably in your air fryer basket or tray. Use parchment paper or foil underneath for easier handling if needed.
Place the meatloaf in the air fryer basket. Cook at 375°F (190°C) for 25–30 minutes. Check halfway through to ensure even cooking.
In a small bowl, mix ketchup with hot sauce or taco sauce. After 20 minutes of cooking, spread the topping over the meatloaf for a flavorful glaze.
Continue air frying until the internal temperature of the meatloaf reaches 160°F (71°C). Use a meat thermometer for accuracy.
Let the meatloaf rest for 5–10 minutes before slicing. Serve with mashed potatoes, roasted veggies, or a fresh Southwest salad.
