Make perfect potato croquettes with a golden, crispy exterior and a creamy, cheesy interior. This recipe uses leftover mashed potatoes to create a satisfying appetizer or side dish.

Ingredients

Scale
  • 3 cups cold, leftover mashed potatoes
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup diced cooked ham (optional, for ham and cheese potato croquettes)
  • 1/4 cup all-purpose flour
  • 2 large eggs, beaten
  • 1 1/2 cups panko breadcrumbs (for extra crispy potato croquettes)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Vegetable oil, for frying

Instructions

  1. In a bowl, gently combine the cold mashed potatoes, shredded cheddar cheese, and diced ham (if using). Mix just until combined; do not overmix.
  2. Place the flour, beaten eggs, and panko breadcrumbs into three separate shallow dishes. Season the flour lightly with salt and pepper.
  3. Scoop about 2 tablespoons of the potato mixture and shape it into a small log or cylinder shape, about 2 inches long. This is your homemade croquette.
  4. Dredge each potato croquette first in the seasoned flour, shaking off any excess.
  5. Dip the floured croquette completely into the beaten egg. Let any excess drip off.
  6. Roll the egg-coated croquette thoroughly in the panko breadcrumbs, pressing lightly to make sure the crumbs adhere well to all surfaces. This step creates the crunchy potato appetizer crust.
  7. Place the breaded croquettes on a baking sheet lined with parchment paper. Chill them in the refrigerator for at least 30 minutes. Chilling helps them hold their shape during frying.
  8. Pour vegetable oil into a deep, heavy-bottomed pot or Dutch oven to a depth of about 2 inches. Heat the oil to 350°F (175°C). Use a thermometer to monitor the temperature for best results.
  9. Carefully place 4 to 5 croquettes into the hot oil, ensuring you do not overcrowd the pot.
  10. Fry for 3 to 4 minutes, turning occasionally, until the potato croquettes are deep golden brown and crispy on all sides.
  11. Use a slotted spoon to remove the croquettes from the oil and place them on a wire rack set over paper towels to drain excess oil.
  12. Serve the crispy potato croquettes immediately as a savory potato snack or party finger food.

Notes

  • For the best texture, your mashed potatoes must be cold. Warm potatoes will make the mixture too soft to shape properly.
  • If you prefer an Italian potato croquettes style, add 1 teaspoon of dried oregano and 1/4 cup of grated Parmesan cheese to the potato mixture before chilling.
  • If you do not want to fry, you can bake these at 400°F (200°C) for 15-20 minutes, flipping halfway, until golden. Frying yields a superior crispy exterior.
