Start by peeling and grating the potatoes, then place them in a bowl of water to rinse off the starch.
After rinsing, transfer the potatoes to a strainer and use paper towels to squeeze out any excess water.
In a clean bowl, season the grated potatoes with salt, pepper, and olive oil, mixing everything together thoroughly.
Heat a pan and add one tablespoon of butter along with the seasoned grated potatoes.
Press the potatoes down with a spatula, then cover with a plate and carefully flip them to cook the other side.
Once cooked, serve the hash browns topped with flaky salt.
