Creating the ultimate hash browns at home is a breeze if you follow these simple steps:

1. Prep the Potatoes: Peel the russet potatoes and grate them using a box grater or food processor.
2. Rinse and Drain: Place the grated potatoes in a bowl of cold water. This helps remove excess starch. Rinse thoroughly and drain well.
3. Squeeze Out Moisture: Use a clean kitchen towel to squeeze out as much moisture as possible from the grated potatoes. This step is crucial for achieving a crispy texture.
4. Chop Onion (Optional): If using onion, finely chop it and mix it with the grated potatoes.
5. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat until shimmering.
6. Add Potatoes: Spread the grated potatoes (and onion, if using) evenly in the skillet. Press down gently with a spatula to form a compact layer.
7. Season: Sprinkle salt, pepper, and any additional spices over the top.
8. Cook: Let the potatoes cook undisturbed for about 5-7 minutes or until golden brown.
9. Flip: Carefully flip the hash browns using a spatula. Cook for an additional 5-7 minutes on the other side until golden and crispy.
10. Serve Hot: Once cooked, transfer the hash browns to a plate lined with paper towels to absorb excess oil. Serve immediately.

These straightforward steps will guide you in creating crispy and delicious hash browns easily.
