**Prepare the Potatoes:** Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat. Grate the potatoes using a box grater or food processor. Place the grated potatoes in a clean kitchen towel and squeeze out as much moisture as possible.

**Mix the Ingredients:** Transfer the grated potatoes to a mixing bowl. Add the chopped onion, olive oil, salt, pepper, garlic powder, and smoked paprika. Toss until well combined.

**Spread the Potatoes:** Evenly spread the potato mixture in a thin layer on the prepared baking sheet. For extra crispiness, press the potatoes down firmly.

**Bake the Hash Browns:** Bake for 20 minutes, then use a spatula to flip the potatoes and bake for an additional 15-20 minutes, or until golden brown and crispy.

**Serve and Enjoy:** Remove from the oven and serve immediately with your favorite breakfast accompaniments.
