Preheat your waffle maker according to the manufacturer's instructions.
In a large bowl, combine the grated potatoes, salt, black pepper, garlic powder, and onion powder. Mix well to ensure the seasonings are evenly distributed.
Add the olive oil to the potato mixture and stir until all the potatoes are coated.
Lightly spray the preheated waffle maker with cooking spray to prevent sticking.
Place half of the potato mixture onto the waffle maker, spreading it evenly.
Close the waffle maker and cook for about 8-10 minutes, or until the hash browns are golden brown and crispy.
Carefully remove the hash browns and repeat with the remaining potato mixture.
Serve hot with your favorite toppings, such as sour cream, chives, or cheese.
