Transform your cold mashed potatoes into golden brown, crispy mashed potato cakes. This easy recipe incorporates cheddar cheese and chives for a comforting side dish or snack ready quickly.

Ingredients

Scale
  • 3 cups leftover mashed potatoes (cold)
  • 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
  • 1/4 cup panko breadcrumbs (optional, for extra crispiness)
  • 3 tablespoons butter or cooking oil, for 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. If using panko breadcrumbs, spread them on a shallow plate.
  3. Scoop about 1/3 cup of the potato mixture and form it into a patty, about 1/2 inch thick. If using panko, lightly press both sides of the patty into the breadcrumbs.
  4. Heat the butter or oil in a large skillet over medium heat. You need enough fat to coat the bottom of the pan.
  5. Carefully place the potato cakes into the hot skillet, ensuring you do not overcrowd the pan. Work in batches if necessary.
  6. Cook for 4 to 6 minutes per side, until the mashed potato cakes are golden brown and crispy on the exterior.
  7. Remove the cooked cakes from the skillet and place them on a plate lined with paper towels to drain excess oil.
  8. Serve your crispy potato cakes immediately as a delicious side dish or snack.

Notes

  • For the crispiest results, ensure your mashed potatoes are cold before mixing.
  • You can bake these at 400°F (200°C) for 15 minutes, flipping halfway, for a healthier option.
  • Air fryer mashed potato cakes work well: spray lightly with oil and cook at 375°F (190°C) for 10-12 minutes, flipping once.
  • Add 2 tablespoons of cooked, crumbled bacon bits to the mixture for loaded mashed potato cakes.
