Step 1

In a large mixing bowl, add mashed potatoes, Parmesan cheese, egg, green onions, flour, garlic powder, salt, and pepper. Mix well until smooth.

Step 2

Use your hands to shape the mashed potato mixture into balls or you can use an ice cream scoop for even pieces.

Step 3

Add dredging flour into a shallow plate and coat each mashed potato balls in flour. Use your hands to gently flatten them into patties. Set aside on a parchment-lined baking pan or plate.

Step 4

Heat 2 tablespoons of oil in a large non-stick skillet over medium heat until the oil sizzles, about 2 minutes. Add patties in batches (about 5-6 per batch) and cook for 4-5 minutes on each side until golden brown. Add 2 tablespoons of oil in the beginning of each batch.

Step 5

Let cool for 5 minutes and serve with sour cream and chives, if desired.
