1½ pounds russet potatoes, peeled and grated (using large holes of box grater)
1 onion, grated (using large holes of box grater)
1 1/2 teaspoons kosher salt
1/2 teaspoon freshly ground black pepper
1/4 cup chopped fresh parsley
How to Make It
Melt the butter over medium heat in a large skillet. Add the potatoes and onion and sauté until tender, about 5 minutes. Season with the salt, pepper, and parsley. Use a spatula to press the potatoes into pan. Cook until a crust forms, about 5 minutes. Using the spatula, break apart the potatoes, press down again, then let stand to form another crust. Cover skillet, reduce heat to medium-low, and cook for 10 minutes more.
