Place grated potatoes in a clean towel or cheesecloth and squeeze out any excess moisture.
In a mixing bowl, combine potatoes, onion, egg, starch, flour, parsley, herbs, salt, and pepper. Mix until well incorporated.
Heat vegetable oil in a skillet over medium heat.
Form the mixture into small patties with your hands or a spoon.
Fry patties for 3–4 minutes per side, or until golden and crispy.
Transfer to a paper towel–lined plate to remove excess oil.
Serve warm with sour cream, garlic yogurt sauce, or a light salad.
