Turn leftover mashed potatoes into golden, crispy pancakes in 25 minutes.

Prep Time:10 minCook Time:15 minTotal Time:25 minServings:4Difficulty:Easy

If you’ve got leftover mashed potatoes sitting in the fridge, don’t reheat them — transform them. These crispy potato pancakes are quick, forgiving, and utterly addictive: creamy potato inside, golden and crunchy outside. They’re the kind of recipe that makes friends and family ask for seconds before you’ve even cleared the pan.

The batter is flexible: add cheese, herbs, or bits of bacon to make them your own, and if your mash is a little wet you can easily firm it up with a splash more flour. Fry them hot and don’t crowd the skillet so each pancake gets a beautifully crisp crust.

    Stir in the flour, green onions, salt, pepper, and garlic powder until a slightly sticky batter forms. Fold in cheese or other add-ins now, if using.

  3. 3

    Heat a large skillet over medium-high heat and add 1 tbsp oil. When hot, drop 1/4-cup portions of the potato mixture into the skillet and flatten gently with a spatula into 3-inch rounds.

Ingredients

  • Leftover mashed potatoes:2 cups
  • Large egg:1 piece
  • All-purpose flour:1/3 cup
  • Chopped green onions:2 tbsp
  • Shredded cheddar (optional):1/2 cup
  • Salt:1 tsp
  • Black pepper:1/2 tsp
  • Garlic powder (optional):1/4 tsp
  • Vegetable oil (for frying):3 tbsp
  • Butter (optional, for flavor):1 tbsp

Tips & Notes

  • If the mashed potatoes are very wet, add up to 2 tbsp more flour or a handful of breadcrumbs until the mixture holds its shape.
  • For extra-crispy edges, fry in a mix of oil and butter and make sure the skillet is hot before adding the pancakes.
  • Make them ahead and reheat in a 375°F oven on a wire rack for 8–10 minutes to restore crispness.
  • Try mixing in cooked bacon, sautéed onions, or fresh herbs for different flavor profiles.
