Step 2

Peel and grate potatoes, then place in a colander and set over a large bowl. Using your hands, squeeze out excess liquid from the potatoes. Pour off liquid and place potatoes in bowl. Grate onion and add to potatoes along with parsley, flour, baking powder, salt, and pepper, and mix well.

Step 4

Preheat oven to 275 degrees. In a large skillet over medium heat, heat a thin layer of oil. Take a heaping tablespoon of batter and flatten it before gently placing it in hot oil. Make three or four more potato pancakes this way, and add to skillet without crowding pan. Fry until golden brown on both sides, turning once, about 8 minutes total.

Step 6

Repeat with remaining potato mixture, adding more oil as necessary. Remove cooked potato pancakes to paper towels to drain, then transfer to an ovenproof platter and keep warm in oven until all pancakes are cooked.
