Easy fried mashed potatoes. All you need are cold leftover mashed potatoes and butter.
Heat the butter in a 10-inch nonstick skillet over medium-low heat. Cook until butter just begins to brown.
Add the cold mashed potatoes. Spread evenly into pan. Cook for about three minutes until the bottom browns. Turn the mashed potatoes with a heatproof-silicone spatula. Repeat until the potatoes are spotted and golden brown. This takes about 10 minutes.
Season with salt and pepper to taste.
Before serving, top as desired. (optional)
