Peel and grate the 4 medium potatoes, then drain excess moisture using a kitchen towel.

In a mixing bowl, combine grated potatoes, shredded mozzarella, salt, black pepper, green onions, and flour, mixing well.

Heat a skillet over medium heat with cooking oil until shimmering.

Shape potato mixture into ½ inch thick pancakes and place in the hot skillet.

Fry each pancake for 3-4 minutes per side until golden brown and crispy.
