While air fryer preheats, add olive oil, salt, garlic powder and onion powder to a large bowl. Stir to combine.
Wash and dry potatoes. Dice into 1 inch cubes and add to the bowl. Stir to coat potatoes in oil and seasonings.
Add potatoes to air fryer basket and cook at 400 degrees F for 18-20 minutes, shaking after 10 minutes.
Plate and enjoy!
Notes
All air fryers cook differently. Pierce the potatoes with a fork before removing from the air fryer to make sure they are cooked through in the center.
Cook time may depend on the size you cut your potatoes. If you cut larger than 1 inch cubes, you may need to increase the cook time.
