Ingredients

Scale

For the Potato Pancakes:

  • 2 cups leftover mashed potatoes (cold)
  • 1 large egg
  • 1/4 cup all-purpose flour (plus more if needed)
  • 1/2 teaspoon salt (adjust to taste)
  • 1/4 teaspoon black pepper
  • 12 cloves garlic, minced (optional)
  • 1/4 cup finely chopped onion (optional)
  • 12 tablespoons fresh chives, chopped (optional)
  • 1/4 to 1/2 cup shredded cheese (optional)
  • Vegetable oil for frying (about 1/2 cup)

For Serving:

 

  • Sour cream
  • Fresh chives or scallions, chopped
  • Applesauce (optional)

Instructions

  • Prepare the Mixture: In a large bowl, combine cold mashed potatoes, egg, flour, salt, pepper, and any optional ingredients (garlic, onion, chives, cheese). Mix with a fork until just combined. Don’t overmix. Let rest for 5-10 minutes.
  • Form the Patties: Wet your hands with cold water. Scoop 1/4 cup of mixture and gently form into a 3-inch diameter patty, about 1/2 inch thick. Place on a plate and repeat with remaining mixture.
  • Heat the Oil: Pour vegetable oil into a large skillet to a depth of 1/4 inch. Heat over medium-high heat until shimmering (350-375°F). Test by dropping a small piece of potato mixture it should sizzle immediately.
  • Fry the Pancakes: Working in batches, carefully place 3-4 patties in the hot oil, leaving space between them. Cook undisturbed for 3-4 minutes until golden brown on the bottom.
  • Flip and Finish: Carefully flip pancakes with a thin spatula. Cook for 2-3 minutes until the second side is golden brown and crispy.

 

  • Drain and Serve: Transfer cooked pancakes to paper towels to drain excess oil. Season with a pinch of salt if desired. Serve immediately with sour cream and fresh chives.

Notes

Recipe Notes:

  • Cold potatoes are essential for the best texture and easiest handling
  • Don’t flip too early wait for a proper golden crust to develop
  • Maintain oil temperature between batches for consistent crispiness
  • Keep finished pancakes warm in a 200°F oven while cooking remaining batches

 

Storage: Refrigerate in an airtight container for up to 4 days or freeze for up to 3 months.
