Peel the potatoes and grate them using a box grater or food processor. Rinse the grated potatoes in cold water to remove excess starch.
Drain the grated potatoes in a colander and press out as much moisture as possible with a clean kitchen towel or paper towels.
In a mixing bowl, combine the drained grated potatoes, salt, black pepper, onion powder, garlic powder, and olive oil. Mix well until the potatoes are evenly coated with the seasonings.
Preheat your air fryer to 375°F (190°C) for about 3-5 minutes.
If desired, line the air fryer basket with parchment paper for easier cleanup. Spread the potato mixture evenly in the air fryer basket in a single layer.
Cook at 375°F (190°C) for 10 minutes. After 10 minutes, use tongs or a spatula to flip the hash browns to ensure even cooking.
Cook for an additional 10 minutes, or until the hash browns are golden and crispy.
Once cooked, remove the hash browns and let them cool slightly before serving. Top with optional toppings if desired.
