Preheat your air fryer to 400°F (200°C).

In a small container, combine 1 teaspoon each of garlic powder, onion powder, and Cajun seasoning. Sprinkle the spice mix evenly over the steaks.

In a shallow bowl, mix together the flour, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and 1 teaspoon of Cajun seasoning.

In a second bowl, whisk together the buttermilk, eggs, and hot sauce (if using).

Dip each seasoned steak into the flour mixture, then into the egg and buttermilk mixture, and finally back into the flour mixture. Make sure each cubed steak is thoroughly coated, shaking off any excess flour.

Generously spray both sides of the steaks with nonstick spray and then place the coated steaks in a single layer in the air fryer basket. Make sure they are not overcrowded.

Air fry the steaks at 400°F (200°C) for 10-12 minutes, very carefully flipping halfway through the cooking time. Cook them until the coating is golden brown and crispy, and the internal temperature of each steak reaches a minimum of 145°F (63°C) when measured with an instant-read thermometer.

Once cooked, remove the crispy chicken fried steaks from the air fryer and set aside. Repeat the process with any remaining steaks if necessary. Serve the chicken fried steaks immediately, topped with white country gravy or brown gravy, and accompanied by mashed potatoes, green beans, or peas.
