Grate the potatoes and onion using a box grater (large holes) or use the grating blade of your food processor. Transfer the grated potatoes to a muslin cloth and squeeze out as much moisture as possible.
Add the grated potatoes to a large bowl with the eggs, matzo meal, garlic powder, salt, and pepper. Mix until well combined and allow it to rest for 5 minutes.
Preheat the Air Fryer to 375F.
Lightly grease your air fryer basket with cooking spray or line it with parchment paper for easy clean up. Add the potato mixture (1/4 cup per latke) into the air fryer in one single layer, flattening with a spatula to form a patty.
Lightly spray the latkes with cooking spray on top and air fry for 8 minutes. Flip them over, spray with more cooking spray, and continue to cook for 4 more minutes, or until golden brown and crisp.
Garnish with fresh chopped chives and serve with sour cream and apple sauce.
Notes
Don't overcrowd the air fryer basket, working in batches will allow you to get crsipy latkes.
