Make crispy, golden brown potato cakes using leftover mashed potatoes, cheese, and a simple coating.

Ingredients

Scale
  • 2 cups leftover mashed potatoes (cold)
  • 1/2 cup shredded sharp cheddar cheese
  • 1 large egg, lightly beaten
  • 1/4 cup all-purpose flour
  • 1 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup Panko breadcrumbs
  • 2 tablespoons vegetable oil (for frying)

Instructions

  1. In a medium bowl, combine the cold mashed potatoes, shredded cheese, beaten egg, flour, onion powder, salt, and pepper. Mix gently until just combined; do not overmix.
  2. Place the Panko breadcrumbs on a shallow plate.
  3. Scoop about 1/4 cup of the potato mixture and form it into a patty, about 1/2 inch thick.
  4. Dredge each patty lightly in the Panko breadcrumbs, pressing gently so the crumbs adhere to both sides.
  5. Heat the vegetable oil in a large skillet over medium heat.
  6. Carefully place the patties in the hot oil, ensuring not to overcrowd the pan. Work in batches if necessary.
  7. Cook for 3 to 4 minutes per side, until the cakes are golden brown and heated through.
  8. Remove the cakes from the skillet and place them on a paper towel-lined plate to drain excess oil.
  9. Serve immediately.

Notes

  • For an air fryer method, lightly spray the breaded patties with cooking spray and air fry at 375 degrees Fahrenheit for 10 to 12 minutes, flipping halfway through, until golden.
  • If your mashed potatoes are very loose, add an extra tablespoon of flour.
  • You can substitute Gruyere or Monterey Jack cheese for cheddar.
