Preheat your oven to 400 degrees Fahrenheit.

Grate the peeled potatoes using a box grater or food processor with a grating attachment.

Place the grated potatoes in a clean kitchen towel and squeeze out as much moisture as possible.

In a large bowl, mix the dried grated potatoes with olive oil, salt, pepper, garlic powder, and onion powder until well combined.

Spread the potato mixture evenly on a baking sheet lined with parchment paper, pressing down slightly.

Bake in the preheated oven for 20-25 minutes, then flip the hash browns over and continue baking for another 20-25 minutes, or until they are golden brown and crispy.

Remove from the oven and serve hot.
