Ingredients:
2 cups mashed potatoes
1 cup all-purpose flour
1 onion, diced
1 egg
½ teaspoon ground black pepper
½ teaspoon salt
½ cup vegetable oil, or as needed
Directions:
Mix mashed potatoes, flour, onion, egg, black pepper, and salt together in a bowl until batter consistency.
Heat vegetable oil in a skillet over medium heat. Drop 4-inch circles of batter into hot oil. Cook until golden brown, about 5 minutes per side. Remove with a slotted spoon and drain on paper towels. Repeat with remaining batter.
