Grate the potatoes and onion in a food processor with a fine shredding/grating disc.
After grating, it's crucial to remove as much moisture as possible from the potatoes and onions. This step ensures the perfect texture for your pancakes.
Transfer the grated potatoes and onions to a large bowl; add the eggs, breadcrumbs, milk, chives or parsley, and garlic. Mix to blend. If the mixture is too loose, add more breadcrumbs.
Shape the batter into 6 to 8 pancakes.
Heat 2 tablespoons of vegetable oil over medium-high heat until it is hot but not smoking.
Add a few pancakes to the hot oil without crowding and cook for 3 to 4 minutes on each side until golden brown and crispy.
Transfer the pancakes to paper towels to drain while cooking the next batch.
Serve hot with sour cream, chives, applesauce, or your favorite toppings.
