Uniform size ensures even cooking.

This removes excess starch and helps with crispiness.

Dry thoroughly before cooking.

  • Pepper
  • Desired seasonings

Step 4: Preheat Air Fryer

Preheat to 380°F (193°C) for 3–5 minutes.

Step 5: Cook

Place cubes in a single layer.

Air fry at 380°F (193°C) for 12–15 minutes, shaking halfway.

Step 6: Check for Doneness

Cubes should be:

  • Golden brown
  • Crispy on edges
  • Soft inside

Step 7: Serve

Serve immediately for best texture.
