This mashed potato patty recipe turns leftover mashed potatoes into tender potato cakes with a crispy, golden outside and soft center. These easy leftover mashed potato patties are delicious for breakfast, served as a simple lunch, or paired with your favorite main dish for dinner.
Combine the cold mashed potatoes, egg, flour, and scallions with a fork until evenly mixed.
Portion the mixture into 1/4-cup scoops and place them on a silicone-lined baking sheet. Freeze for 10 minutes to firm up the mixture.
Shape each chilled portion into a 1/2-inch-thick patty.
Heat the olive oil in a skillet over medium heat. Fry the patties in batches for 3 to 4 minutes per side, until crisp and golden on the outside and heated through.
Serve hot with your favorite dipping sauce.
Notes
The consistency of leftover mashed potatoes varies. If the mixture is too soft to hold its shape, add a little more flour as needed.
Taste before adding any additional seasoning, as the mashed potatoes may already be well seasoned.
Refrigerate leftover cooked patties in an airtight container for up to 3 days. Reheat in a lightly oiled skillet until hot and crisp.
Freeze cooked patties individually until firm, then transfer to a freezer-safe container or bag for up to 3 months. Thaw overnight in the refrigerator before reheating in a skillet.
