Fill a large bowl with cold water and set aside.
Peel the potatoes and shred them with a box grater or the shredder attachment of a food processor.
Put the shredded potatoes in the bowl of water and let them rest for 20 minutes.
Preheat your air fryer to 400°F (200° C).
Drain and rinse the potatoes. Wipe the bowl out with a paper towel, and put the potatoes back in the bowl. Microwave them for 3 minutes.
Transfer the potatoes to a paper towel or a clean tea towel.. Cover them with another paper towel and squeeze out any excess water. If using a tea towel, squeeze as much water out as you can.
Transfer the shredded potatoes back to the bowl and add the olive oil, chopped red onion, garlic powder, onion powder and breadcrumbs.
Spray your air fryer with cooking spray to prevent sticking.
Shape the mixture into individual disks shapes and put them in the air fryer in a single layer. You might need to work in batches, depending on how big your air fryer is.
Air fry for 15 minutes, flipping once half way through.
