Transform your leftover mashed potatoes into crispy, golden potato cakes. These easy mashed potato cakes are crunchy outside and creamy inside, perfect as a quick side dish or savory snack.

Ingredients

Scale
  • 3 cups cold leftover mashed potatoes
  • 1 large egg, lightly beaten
  • 1/2 cup all-purpose flour
  • 1/2 cup shredded sharp cheddar cheese
  • 2 tablespoons chopped fresh chives
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 3 tablespoons butter or oil, for pan-frying

Instructions

  1. In a medium bowl, combine the cold mashed potatoes, beaten egg, flour, cheddar cheese, chives, garlic powder, salt, and pepper. Mix gently until just combined. Do not overmix.
  2. Form the mixture into small patties, about 1/2 inch thick and 2 to 3 inches wide. You should get about 8 to 10 cakes.
  3. For Pan-Frying: Heat the butter or oil in a large skillet over medium heat until shimmering. Carefully place the potato cakes in the hot skillet, ensuring not to crowd the pan. Cook for 4 to 5 minutes per side, until deeply golden brown and crispy.
  4. For Air Frying: Preheat your air fryer to 375°F (190°C). Lightly spray the air fryer basket with cooking spray. Place the potato cakes in a single layer in the basket, spraying the tops lightly with oil. Cook for 10 to 12 minutes, flipping halfway through, until golden and crisp.
  5. Remove the crispy potato cakes from the heat and place them on a plate lined with paper towels to drain any excess oil.
  6. Serve immediately with sour cream or your favorite toppings.

Notes

  • Use cold mashed potatoes; this is the secret to firm patties that hold their shape.
  • If your leftover mash is very soft, add 1 extra tablespoon of flour until the mixture is workable.
  • For loaded mashed potato cakes, mix in 1/4 cup cooked, crumbled bacon along with the cheese and chives.
