Heat up oil in a large skillet for frying. Process potatoes and the onion in a food processor fitted with the grater blade. Transfer the mixture to a large bowl, and strain any liquid that has pooled to the bottom.
Add in the remaining ingredients and mix well. Form the latkes into a ball shape and carefully transfer to the hot oil. Flatten with a spatula and cook until golden. Flip and cook the other side.
Remove from the oil and place on a paper towel lined plate. Repeat with remaining mixture.
